Topic: [WTS] PaperLedger - Open source custom made crypto price ticker with alarms (Read 1389 times)

Hello i am interested i sent pm

$60 shipped? Make a offer if you think it's too much.
I figured it's a bit less then you would pay if you bought the parts and had a local place 3D print the case (at least around here) local 3d printing prices all over the place.
If you have your own 3d printer it's a different story.

I got a PM from a new user yesterday asking about it, so to be fair I want to give them a day or 2 to get back to me.

-Dave

how much are you looking for it?

Since the back end is still working as far as I can tell I would guess that at some point they figured out that there was no money to be made doing the hardware and went on to other projects. Or, like me figured "oh, this will take 'x' hours to do' and then found out that the 'x' amount was off by an large amount and dropped working on it.

As you said it's open source so anyone with the time can pick it up and run with it.

-Dave

may be interested. Wonder what happen to the developer? Since this is open source wonder if he is ok if development continues?

Sorry to necro bump this after close to two years, but I was cleaning up and found one of these.
Don't know if anyone is interested in them anymore but if you want one and are US based make me an offer.
Tested working. Can get you pictures if you want.

PM or post here.

-Dave

I lost my first PaperLedger, so I'm excited to either buy another one or gank the battery powered one.

any updates about the status of the battery powered model?

You can always have 2 product lines.
Sell the classic at a discount and the battery powered one for more.

I am also going to do some more router testing later this week. I was thinking about it the the one it is connecting to is an old one I keep in my office for the tech bench. That could be part of the issue.
Going to try the main office Wi-Fi, but I have to do that after hours. If I start bouncing it up and down during the work day it would be bad.

-Dave

Thank you for testing this.

I have implemented the battery and there is only a few issues to solve and testing before the new device becomes available.
Along with the battery comes a major firmware update that incorporates a Status bar that provides more information of the device connectivity.
The connectivity is handled slightly differently with the new firmware but i'll make sure to test router outages in order to ensure that if something happens at least the user is informed.

One thing to note is that due to the battery requirements unfortunately the main board and the case need to be upgraded.
Maybe i'll come up with a retrofit package only available for legacy devices.

Did some testing:
If I pull the wan port cable from the router and plug it back in ~ 5 minutes later it's fine.
If I pull the wan port cable from the router and plug it back in ~ 30 minutes later it stops updating and never comes back.
If I pull the power from the router and wait a minute and plug it back it in may or may not start updating.
If I pull the power from the router and wait a good long time (20+ minutes)and plug it back in it seems to start updating.

Did not do "extensive" testing just 2 or 3 tests for each due to the time involved in some of the testing.

-Dave

Fairly well.
For some reason every now and then it stops updating and I have to reboot it.
I *think* that when the router looses internet is when it happens, I have to actually test that to verify.

-Dave

Hi Dave, great timing.

I have been in contact with the board manufacture and have received the new boards last week.
Planning on doing the necessary software/hardware changes over this weekend and will post some updates then.

How is your device going?

Any luck with the battery powered option?
Have not seen any updates on github since mid May.

-Dave

At the moment the device is still usb powered but some work has been done towards converting them into battery power.

The most time consuming actions would be some potential changes to the case layout in order to refit the battery charging port and on/off switch and rewiring the charging circuit to the external usb port.
Although time consuming these modifications can be made rather quickly if enough effort is put into it.

I have some spare time next week and I will actively work on it and keep you updated.

Progress can be followed here:
https://github.com/AIFanatic/PaperLedger/issues/50

any status updates, concerning the progress of the battery-powered model? 

Yes, it's there, it looks like it's getting worse
With the screen all black screen with my phone camera you can't see any of the missing pixels but you can see more missing here.
Unless it's May C9 2019.

I will pull the back off later and see if putting some pressure on the corner fixes it. I fixed a 1st gen kindle that way once.....



Thanks,
Dave

Good to know that the first situation seems to be addressed.

In regards to the line, can you please send the following payload to the device:

The screen should turn all black and will be easier to check for "missing lines", not to be confused with the normal artefacts that caused by how ePaper displays work.

I'm not seeing it on mine.

So, it's been 2 weeks or so. No more crashing / so the new firmware seems to have fixed it.
Still has the line. Anyone else seeing it?

-Dave

Updated the firmware.

Signal -40dBm
Will keep you posted about the going to the attempting to connect screen.
And it turns out it looks like I have a dead line of pixels on top or is this just the way it's being displayed?



Thanks,
Dave

If you have a chance please flash the firmware.bin file located at: https://github.com/AIFanatic/PaperLedger/files/3121298/firmware.zip

The update can be performed through the web portal->settings->update firmware

This build includes the ticker updated time which should provide some more information on what could be happening. (thanks BitcoinMitchell for putting the effort into the project)

Also, if possible, can you let me know the wifi signal strength of the device? (setup->status->network signal) I suspect it may be getting stuck while fetching the tickers.

And I came into the office this morning and it was on that screen again.
Seems to be random. But I really don't know if it went off @ 7:01 PM last night as I walked out or 8:45 AM this morning just before I walked in

-Dave

Just happened now.
It is this screen:


The left button does work.

-Dave

I don't think any of the buttons work. Next time it happens I will give them all a good push to test again. Since pulling the USB and putting it back in works that has been my regular fix.
I don't know if it's consistent, but it does happen regularly say once every few days. Not sure if it's every "X" days or "X" hours. I'll pay more attention.
Now that you ask I am not 100% sure of which screen it is on, next time it happens I will let you know.

Thanks
Dave

Does the device go to the "Welcome to PaperLedger" screen or the "No Internet" screen?
None of the 4 buttons work? At least the left button should work as its hardwired to the reset pin on the board.
The ok button (3 button from left to right) its also mapped through software and should take you to the setup menu.
If the ok button does not work it seems that the device is getting stuck.
Is this consistent? Say after 2 weeks the issue happens?

Thanks for reporting this issue.

Same here. Pretty minor issue, but annoying when it happens.

Having an odd issue every now and then. The ledger will go to the connecting to internet screen and stay there. None of the buttons work when this happens. A 1 second pull of the USB cable and plugging it back in and it's good to go.

Is anyone else seeing this?

-Dave

I've received my PaperLedger a few days ago and I've been very pleased with it. I did notice that weird price that was displayed because of CoinGecko, so I'll try and add BitcoinAverage to the device.

Hi StackGambler,

The prices are pulled from CoinGecko, I have noticed the same thing yesterday and CoinGecko was showing the same price ~$4700.
Was weird that when the website first loaded it was showing ~$5000 then quickly changed to ~$4700, seems to be a bug on their end.

Where is price data pulled from? My PaperLedger shows the price of BTC as $4704 (it's been refreshing, and in that range for the last few minutes) even though the current price is $5,000+ on most major exchanges (Bitfinex, Bitstamp, Coinbase, etc). Think it's a bug, or am I just missing something? I also tried removing and re-adding the ticker.

Hey tweetious,

Yes the battery version will work with both external power source and the battery at the same time, no need to disconnect it.
When connected to an external power source it will charge the battery (very similar to charging a phone).
There is a power switch that is not used at the moment that needs to be made functional since, with battery, the device will be on all the time, although this probably can be handled with software by putting the device into sleep mode.

My wallet is ready, waiting.... when your battery-powered model will be ready.  

Will this model work with external power source (usb cable) as well? will I have to manually disconnect the battery (in order to plug it to a power source)?  Or I will be able to plug it into power, even with the battery attached? (model will have something like an internal switch, when external power is discovered, to disable the battery source)

Posted some thoughts on your product on my channel 

Glad you got it working

And here is a little teaser:

Thank you for the prompt and detailed reply! Browsing through the device's IP worked like a charm; I added a bitcoin ticker and the device looks great. Thanks for this it's perfect! Do shoot me a PM when you come out with a version that has a battery; I'll be the first to buy it.

Hi StackGambler,

Have you tried browsing through the device IP? It should be 192.168.1.1 (http://192.168.1.1)
Note that its not "https", some browsers redirect to https by default.

If you are using a VPN or similar the IP's may clash and it will give similar symptoms to what you are describing.
Seems unlikely since you mentioned that both the phone and pc give the same results but on the phone it may be a DNS issue.

To further debug please do the following:
1 - Connect to the PaperLedger network
2 - Open a terminal/command prompt
3 - If on windows type ipconfig, if on mac/linux type ifconfig (if ifconfig does not work type ip addr)
4 - Look for the wireless interface and see if there is any ip's mentioned on the gateway entry
5 - Type ping ip (ping 192.168.1.1)
6 - If ping does not come with a time out message it means that your computer is able to "see" the device and you should be able to browse it using http://192.168.1.1

Hey, I'm running into an issue when attempting to connect the device to WiFi (might be on my end). The device is on, the WiFi network shows on my computer, but when I try connecting to paperledger.local whilst connected to PaperLedger's network, it shows either a blank white screen, "domain not found" or "no internet". I got the same result on both my computer and my phone. Any ideas?

I received my PaperLedger today. Very happy with my name on the e-ink display; wonderful touch! I haven't gotten the chance to set it up yet, but it looks very promising. Thanks for a swift delivery and a smooth deal!

I'll play with it and see.
Had another idea of adding it to the rotation of coins. Screen would go BTC--> LTC --> ETH --> Last Update Time --> BTC and so on.

Will try some other ideas also too so if they work.

-Dave

Hi DaveF,

Do you have an idea on where the last update time could be placed?
It was in my plans to have the time and the data is already being stored but I could not find a place to put it that fits and is clearly visible.

The device has certain API's that can be accessed through wifi and you can draw any text into the display using the following format:


Example using cUrl:

Note: You may have to replace paperledger.local with the device ip which can be found in Setup->Status->Network IP

Can you add to the display last time updated? Mine was going thought the cycle showing yesterdays prices for some reason.
Gave it a reboot and all is good again.

Thanks,
Dave

Haha. That makes sense. Will follow the topic and wait for the wallet.

Hi stanlee2018,

Not offensive at all, all feedback is good feedback.

This product is more like a gimmick/niche product for crypto enthusiast that are looking for something different/unique.

Similar to wearing a watch or having a custom crypto painting for example.

Also keep in mind that a full fledged wallet is planned to be incorporated when time allows, this would bring some more usable functionality to the product.

I am not offending, but I do not understand, why I should use this? I can just download an app on my phone to help me to monitor and alerts me.

I have added the list of materials required to build a device.
It can be found here

The assembly guide will come shortly.

If you do build one please post a screenshot.

Happy building!

Hi gr3y,

I'm still waiting on the batteries to arrive.

I still have to publish the BOM list of the project but essentially the device consists of a TTGO ePaper ESP32 2.9' v2.2 and a micro usb breakout board.

Will update the GitHub page maybe on the weekend with some assembly guide to.

Any update on battery version?

You said you open sourced it but I can't find a hardware list?  I have a 3D printer and would love to build this from scratch with my son!  Awesome work!!

Pop off back. 1 Small piece of black electrical tape and poof no more green light shining through the case.
-Dave

Bummer. Sitting in a dark room it's annoying. Will have to take it apart to see what I can do.

Yes it is, I did not see it the 1st time around. It's there now. Strange.


Excellent. 

Thanks,
Dave

Hi Dave,

I'm sorry for that, my handwriting is not the best.

Q: can I turn off the green light?
A: Don't believe you can, the LED seems to be hardwired to the power line and I've tried to turn all the available pins off and it does not change the state of the power LED.

Q: can you add GBYTE to the choice of coins.
A: Is GBYTE called OBYTE? (https://coinmarketcap.com/currencies/obyte/). If so, OBYTE is in the list of available coins, by searching for it in the coin input box it will show up.

Q: since you are 3d printing the case can you post the STL files so we can print different ones?
A: Yes, I have decided to fully open source PaperLedger. You can get the frontend, firmware and hardware at https://github.com/AIFanatic/PaperLedger

Got mine in yesterday.
Would have been here sooner but someone (let call them PooperLedger) put the wrong zip code on the international pack so it took a trip around Texas before coming to New York
[Bryan TX = 77803 Plainview NY = 11803]

Love it and it's working great.

Question #1, can I turn off the green light?
Question #2, can you add GBYTE to the choice of coins.
Question #3, since you are 3d printing the case can you post the STL files so we can print different ones?

Thanks,
Dave

It's a great unit and for it's price you get more than you probably deserve. Enjoy it!

I've paid for a unit. I'll let you guys know when it comes in. This does indeed look promising: I've been looking for an ePaper price tracker for quite a while. The price is pretty good, too!

Keep up the good work and you'll get there in no time. I'm very hopeful about any updates/improvements you'll make, this thing is really great and I've had a bunch of different tickets that are either very big or have very strange software. Love your dashboard, you'll be able to build upon that a lot I reckon.

Thanks again

Hi Hhampuz,

Thank you so much for your honest feedback.

I will address the cons as soon as possible and work towards a 10/10.

Again, thank you very much.

Got my PaperLedger today and have to say I'm impressed.

Firstly, the welcome message with my username is an awesome touch, thank you for that one guys!

Pros:
Easy to setup (Literally 60s).
Lightweight unit.
Connects to wi-fi without issues.
Dashboard is GREAT!
Screen quality is absolutely gorgeous. Very clear both when it's dark and if the sun is shining right on it, so that's a big pro.
Seemingly an endless supply of coins that can be added as tickers.

Cons:
Some issues with the guide, I had to disconnect/connect power once I had connected to my wi-fi although guide said it would reboot automatically. But that's just some print that can be edited (and it's a non-issue).
The buttons on the top are bit wonky, they work great but can be slow (having to wait 1-2s before being able to move the arrow again for example). This could probably be better optimized but again, not a big con.
Adding tickers was a bit confusing. When I wanted to add BTC it gave me like 100 hits with coins that I don't even think exist, it would be great if it could default to the big coins when you do search (and perhaps even if you don't search it could show you the top 10 or whatever). There was no guide on how you add tickers but through the dashboard it is very straightforward and no explanation was needed.

---

After having used plenty of tickers through the years I'll rate this 8/10 with room for improvement. The overall quality and how easy it is to setup and get it going really pushes that rating up there.

Considering you're tinkering with having it run on battery I'd say it'll be a homerun, especially with the pricetag you currently have on it.

Keep up the good work guys, I'll def. buy some of these and if you'll introduce skins as well that will only enhance it all and make me more prone to buying and give away to friends/family.

Thank you for the response. Kindly PM me an address, and I will send over the funds when I have them ready. Appreciate it!

Hi StackGambler, thank you for your interest and feedback.

Q: Do you ship to Singapore?
A: Yes

Q: I don't have the money right now, but I will get it soon. When I get the money, I will forward it to the BTC address you provide to me via PM. Can I send you 59+12 USD based on the preev.com conversion rate at the time, or must I confirm with you before I send the BTC? (I will probably be able to purchase this within a week or two.)
A: The rate will be taken at the time of purchase and you can send the BTC without confirmatin. Although you can use preev.com I would prefer something like coinmarketcap since the rates are auditable.

Let me know if you would like me to send you an address, alternatively I will be available when your ready to purchase.

Hi lucianus_luciferus, thanks for your feedback.

The cases should be smooth, the pattern that is seen in the photos is due to them being 3D printed.
Usually with most FDM 3D printers you can see the individual layers, thus why I mention that quality is the biggest issue with different colors.
White filament reflects light really well so its almost imperceptible, with red it becomes more noticeable and black is the hardest (at least in my experience).
The glossy finish is because the cases are being printed on glass, the sides of the case are opaque.

Nice thinking on the gold, actually I have some gold filament available, will definitely give it a shoot and report back.

this is so cool! do the cases have some kind of pattern on them? it sure looks like that from the pictures.
when you do the black cases pls post a pic. a gold case would be cool for bitcoin lovers

Quick update:
- Added a basic documentation on how to perform the initial setup https://github.com/AIFanatic/PaperLedger/blob/master/docs/setup.md
- Red case sneak peak

Hi wheelz1200,

I have just run some tests and the device supports 100+ tickers, running with 105 and there is still plenty of RAM available.
The support for scrolling is already implemented and the user can customise the scrolling rate (defaults to 10 seconds per ticker).

Here are some screenshots:

Pretty  nice looking ticker.  I'd probably be interested in one if you can monitor a bunch of coins.  Will wait for your test report but I'd probably be interested in one for sure if it can handle a bunch of different coins with a scrolling ticket function.  Watching, thanks.

Hi tweetious, thank you for your feedback.

After a very quick assessment there are a lot of batteries that will fit without any case changes, mostly ~600mah, at around ~1200mah the case would have to grow around 3mm in thickness.

It seems that there is a general demand for portability and as such I will start working on incorporating a battery into the device and the proper software changes and report back.

I am interested in getting one that works with a battery (as krogothmanhattan said, I also bought a ticker from another Aussie & have 1-2 more different tickers, but none of them works with a battery). However, since it will need a new case (to fit the battery) it would be a step to pay additional shipping fees (+ case cost),  just for the new case delivery.

Hence, whenever you are ready with the battery integrated model, just let us know

Very nice indeed. Will think about this as I already bought a ticker from another Aussie last year.

Hi Zebedee23, thank you for your interest.

Q: can u do in different colours??
A: Soon I will have red and black available (quality is the biggest issue when dealing with different colors).

Q: How many coins can u keep track of and does it scroll through yr coins automatically???
A: I have not tested this (will report back once tested), but I would say 20+. Yes, the device scrolls the coins automatically and the scroll frequency can be adjusted in the settings tab of the web portal (defaults to 10 seconds per coin). You can also re-arrange the order of the coins in the web portal by dragging them to a new place on the list.

Regards,
PaperLedger

Hi klaaas,

Q: When you are saying that it is in your plans to add the battery, what do you mean? You will release a different model that supports a battery, or all the previous sold models, will be compatible with the battery integration?
A: All of the devices are already compatible with a battery, as the electronics already have a battery connector and a charging circuit. At the most the case will have to change in order to fit in the battery.

Q: What do you mean "Some similar devices can run for more than 1 year on a single charge". So, can we charge this device (and hence work without a constant power supply) or not?
A: The current model does not come with a battery. Firmware adjustments will have to be made, as at the moment the goal was not to make the device power friendly.

Q: Any other color case option, except of white?
A: Soon I will have red and black available (quality is the biggest issue when dealing with different colors).

Q: Does the device work over Wi-Fi?
A: Correct, soon I will post a guide on how to perform the initial setup. Basically the device create an access point if no wifi is found named PaperLedger. The user then connects to the access point and browses the web portal at http://paperledger.local. A prompt will appear to setup the network. Once that's done the device will connect to the wifi and tickers/alarms can be added using the web portal

Hope this answers your questions.

looks good , can u do in different colours?? How many coins can u keep track of and does it scroll through yr coins automatically??? definitely interested

Looks really nice! I will wait for first review and maybe buy one!

So, in the current state, it works (i.e. takes power) only if it is connected with a micro usb cable. When you are saying that it is in your plans to add the battery, what do you mean? You will release a different model that supports a battery, or all the previous sold models, will be compatible with the battery integration?

What do you mean "Some similar devices can run for more than 1 year on a single charge". So, can we charge this device (and hence work without a constant power supply) or not?

Any other color case option, except of white?
Does the device work over Wi-Fi?

Hi klaaas, thank you for your interest.

Yes, the last image will be retained until the next boot cycle (in the photos the device is not powered on).

At the moment it only runs out of a micro usb cable, but the pcb inside already has a battery connector and charger.

It is within my plans to add the battery and make it more power efficient.

Some similar devices can run for more than 1 year on a single charge (querying data once a day) and using deep sleep.

Cool ticker with cool features to come!  I like this case design with a epaper display.
When i turn off the device will the last image remain visible ?

Does it run on a battery ? if so how long ?

+1 for review!

Thank you for your feedback, PM sent.

I'd gladly review this product, it looks neat!
