Question already asked, Can i re-use an old Pie first model with the 821 software or a Pie 3 is necessary ?

Yes, there are three versions of the A821 OpenWrt software.

One version for the Raspberry Pi 1.
One version for the Raspberry Pi 2.
And one version for the Raspberry Pi 3.

Thanks !

I ordered a separate one so I won't have to worry.  Not worth saving $100 to risk a $2000+ machine.  I'd say run all 741's on 1 controller, and all 821's on another controller.  Don't mix and match and won't have any worry.

This also applies to mixing A721 and 741's on 1 RiPi. To be specific, the A7/A8 on one controller caveat is to not flash the MM firmware (inside the miner on daughterboard) with both A7/A8 on 1 controller as it is applied to all miners at the same time. Only other thing to remember is that if you play withe voltage offset option, again, it will apply to all miners.

Sooo, just get a RiPi-3 from Amazon or whoever for $30-40, a nice case for it and flash the SD card with the latest controller firmware (which is really software....) from Canaan .

do you think this officially means that the 741 and 821 will need separate controllers? last i spoke with blokforge they werent sure if the 741 and 821 would be able to daisy chain together on the same controller--and that they would have to test it first on their end before they knew---hoping to be able to save a few bucks and use the same controller i have for my 741s now!

Someone posted on this thread already before it will be supported. You have to make sure you don't flash the firmware for example which would corrupt one of the miners.

I see blokforge has the avalon controllers in stock to buy for the 821 firmware now.  Just a heads up everyone who was waiting besides myself!

Here's the thing people. Stop complaining;  Wink

Unlike every other company out they go out of there way to list any extra units that become available for forum members. They even carve out a small slice for us from the main order.

It does suck when you try and can't get through or you happen to get there to late. I'm sure they will try and fix it, but really if you get to the end and it says out of stock, take a minute breathe, and then act like you just got there and there were none available.

If people keep shitting on their efforts where is the incentive for them to come here and give us a shot at units, and even a slight discount sometimes.

Yes, we are whining a bit, but it could all be avoided with a page that reads that they are having difficulties and aren't  able to fulfill sales like they had hoped(bug is you can get it in your cart but it immediately become invalid).   A little  transparency and honesty goes a long way.   We understand there being no availability, and not getting it in your cart to begin with. We just don't understand why it gets pulled from your cart - probably given to someone who was lucky enough to not experience the problem.

By the way I replicated this on three different machines running three different operating systems using a different browser on each machine(IOS/Windows/Linux using Safari/Firefox/Chrome). So I feel certain this is a shopping cart bug and not an browser/cookie/security settings issue. 

4876 people trying to simultaneously buy less than 200 units.  cart just has problems on the last few, its millliseconds between stock removal and addition for the last few.  It is not that it is getting pulled from your cart, the front end caching is not caught up with the backend and it was not available to begin with.  If you can replicate a way to have 4000 people checkout at the same time on three different browsers, send us a resume.  But for the few that emailed us saying they had problems and didnt tell us to eat a d**k we took care of them. Smiley

I wasn't complaining so much as I was pushing back a little bit against somebody who simply said we should be quiet and not say anything. I certainly could do without a miner and can wait for another batch.   And all of us do appreciate you putting a nice batch of miners - at a nice price I might add - up for sale for us.

My guess is quantities are getting committed to carts, not stock IDs. I am software engineer for a large national retailer and I work on the backend systems that support the web site.   When the website wants to commit a quantity, we return them a stock ID which is dynamically generated at the time. That stock ID is associated with the quantity for as long is the cart/session ID from the website is valid.  If they haven't tender a sale with that stock ID by the session expiration, the quantity is return to the inventory column. Works for us, so might work for you?  I am also somewhat familiar with woocommerce - familiar enough that I do understand your limitations and my suggestion  would require a customization to woocommerce on your part.  So it may not be feasible.

Thanks again and sorry if any frustration on my part came through in my posts.


We do not take any comments personal, I know the frustration.

The main problem is the handoff between the cart and the actual payment processing system, the sytem needs to hold inventory at different time intervals depending on what payment method is chosen as you know a bitcoin payment cannot be confirmed within 10-15 minutes, and we cannot risk letting inventory go from someone that has a processing payment.  We also cannot let items sit in peoples carts for 200 minutes while they just go watch a movie while people are trying to buy.

To answer the other comment here  after our first sale, we changed servers, and altered the site to handle the load, and thousands of sessions at once, we do not feel that is the issue at more as i am sure people saw, its the backend syncing with the front end when there are only 1 or 2 units left, and carts trying to hand to backend, than to payment processing sytem, than back and forth again.  Bitmain has billions of dollars and still has the issue, just only the last few orders see it, till they just pull the plug on the sale, lock inventory and clear carts "out of storage".  Nevertheless we are working on it.

Actually there are several companies that can do order systems front and back-end stress-testing on any scale you need.

On larger scales the likes of Amazon and CC companies et al, yes that is done in-house. A friend of mine with Phd in CS used to head AMEX's on-line services QA lab in Miami where they routinely simulated 10's of thousands of simultaneous customer sessions using every imaginable browser & OS configurations to verify the on-line sessions worked before taking changes live.

I can understand fighting for the cart, but after you finally get it you shouldnt have to have it suddenly removed again while filling out payment details. That just doesnt make sense. I feel like I had much less opportunity because I dont have some sort of strong fiber optic cable connection. I just wasted my time refreshing the carts and payment for 2 hours without getting anywhere. Would have gotten 6, then tried 3, then tried just 1. If future sales are the same then im not sure what to make of this particular distributor.

I only started buying new miners back in August; but have found it's often the same. You have so many people trying to buy a small amount.

Just visualize those insane black Friday videos we've all seen.

Like they said before if you email them and let them know the issue you had they try their best to make it up to you or help you out with a cancelled order

I can confirm that Blokforge does support their customers - they came through for me on a couple of transactions.  Based on the purchases I have done and their response to those of us in the forum, I will look there first for new miner related products in the future.  Hopefully when the 841s come out they will be priced competitively to the S9s, the 821s or whatever else maybe on the market and will be available from Blokforge.

I got one of the pricey 821s (with help from Blokforge)  snip

I'm actually a little surprised to see the final March pricing.  I wanted it to be $15-2000 like everyone else, but given the final price from Canaan $2900 was very reasonable.  Without hitching a ride on what really makes money on Broadway Road in Arizona I'm not sure we would be having a discussion at all.  Smiley  The overhead and HR resources to do what Blokforge is doing for us is pretty generous IMO.

I hope that they get bigger batches in the future to help justify this activity and guarantee we continue have the representation that we take advantage of.  Smiley

So I feel certain this is a shopping cart bug and not an browser/cookie/security settings issue. 

It's just how WooCommerce works with holding stock and pending orders. It doesn't subtract actual stock until an order is changed to processing. That doesn't happen until payment is confirmed.  The remaining few that you could still add to cart but not checkout were most likely stock from pending orders paid with BTC that didn't confirm yet. The message I saw showed pending orders cancelling after 80 minutes and I was able to checkout then. When the site is essentially under a DoS attack, it will make it more difficult.

"When the site is essentially under a DoS attack"

You mentioned you used auto-refresh... you didn't mention how much you were using it.. but then talk about waiting people out like you were part of the attack.
 
And who knows what other people were doing..  probably even worse

WooCommerce at it's finest. Did the guy complaining about Pangolin's Woo try getting one of these? lol

I had to automatically keep adding to cart for over an hour straight when there were only 6 left because of stock hold and everyone else doing the same. Once in cart, I had on auto-refresh and it would sometimes show the checkout but never go through due to pending orders/held stock. Sometimes it'd show FTP login too, so site was getting hammered. After an hour, others seemed to have given up, I checked out fine, and there were still a few left.

I got one of the pricey 821s (with help from Blokforge) but I do not have any regrets.  Those who bought knew they were taking a risk of never being super profitable.  Personally, I see mining as a risky investment - I mine as long as possible to get coins with the firm belief bitcoin will keep rising over the next 10-15 years.  Also, getting the Avalon miners is the best option if you are like me and run them at home in a spare room or basement.  I do not have a data center to properly house the crap jet-engine/unreliable hardware from Bitmain (I know they are industrial but they are still crappily built machines).  The 741s run so much better (cooler, quieter and with almost no failures) than any of the S5, S7, or S9s I have used (about 20 of them over the last three years).  Hopefully, the 821s (and 841s) will be just as good.
 
It sounds like some of the buyers are cancelling their 821 orders after the fact (possibly because the prices are going back down).  Unless there is a true hardship (like losing your job or health), this just doesn't seem honest - I guess I am an optimist or a fool!

Finally,  I am a supporter of Blokforge - it is nice to have a trustworthy place to buy from in the US.
