and I think Ledger wallet would be hardest to reproduce as they are not 100% open source.

I doubt you could even obtain the propriety part (secure element), let alone combine it with other parts.

Although not 100% "DIY" coldcard has their entire build here:

Cool.
Not sure if anyone managed  to do this with Coldcard wallet and what the total price would be.

I guess you need to have strong will and nerves to make any DIY hardware wallet,
and I think Ledger wallet would be hardest to reproduce as they are not 100% open source.

When they 1st published it the price was ~$75 for 90% of the parts, picked up from local shops.
But, there are a few industrial areas somewhat near to me, and they all have 1 or 2 small electronic places in them.
Going online and ordering @ quantity 1 is probably going to cost more.

Do you know any better DYI hardware wallets?

Firmware, hardware, and part numbers.
From the security standpoint it's nice to build your own.
From the reliability standpoint...I guess it's how good are you working on soldering stuff to PCBs :-)

Is it worth the effort?

I don't think so, as you can buy brand new Trezor wallet if you pay just a bit more, or wait for some discounts,
but if you are tech geek and want to make your own custom stuff, then why not  Grin

I believe this might be worth the effort in countries where ledger/trezor do not ship wallets, specially developing countries with high taxes/fees/corruption for international shipments.

There should be some video in you tube teaching how to do that and which components to buy more precisely. But this is a very interesting solution for many people, certainly.

let's say it might be worth it and it might not make much sense to create it when you can buy it for just over $ 40, but I look to the creative side and it's a great pleasure for geeks to create the hardware of your wallet, I'm also working on creating it one of my using the trezor code, if I succeed I will write a special thread. in the meantime, thanks for the guide which is really fantastic

This is awesome !
Nevermind the 8$ saved, the concept is great.

Everybody knows what a trezor should look like,  but if you build it yourself and put it into a shape that is different you can hide it in plain sight.

Like, a TV remote control Trezor where the screen is hidden where the batteries (AA) are supposed to be.

Or even an old-style calculator, no one is going to steal a $20 texas instrument calculator.

Brilliant

For a DIY raspi zero and Trezor combo check out this project
and make your self a PiTrezor.
I could not find total price for this device on that blog post, but that is very cool combination HW to see.
It should be noted that private key will be stored on SD card, so you would need to take good care of it
and add extra password for protection.

Is it worth the effort?

I don't think so

I also believe that it doesn't worth the effort if the only goal is to save some bucks.
If you are into electronics, OK, it can be an interesting (short) project, but if you don't, you may end up breaking some parts and paying more at the end. ("It's hard to solder those without magnification", even the video tells that).

Also keep in mind that a Trezor is nowadays 59 EUR, not 89 EUR, like the (start of the) video shows.


Overall, I liked the idea, I'm going to save the YouTube link and maybe even make it again before the end of this year.

If you want to make sure you'll have it, I advise you save the video (mp4) not the link. It's a more.. future proof option.

It was worth the effort, but he did not explain in detail all the hardware parts or PCBs connection.
The 3D cover/case is not important.
It would be fun to start with it or check it out.

Shipping takes a lot of time so you will need a lot of enthusiasm to do so.

I did made few my own homemade electronic stuff, not for saving any money but more to make them custom and unique.
Geeks are crazy sometimes  Grin

There are some things money can't buy! Grin
Sometimes, you just want to be able to make something with your own two hands that gives you so much pleasure. At least that's the way I feel about it.

Too much hassle and time consuming for an 8$ savings and you can't guarantee the quality of the outcome. I believe even tech geek will not gonna do this DIY unless they have already spare parts for the required materials to build it. I believe the author didn't include the shipping for purchasing the parts since it is most probably not available in one shop.

I will not personally attempt to do this because I know that I'm gonna messed up on doing this. In summary, It's good to know that we can DIY a trezor which is very cool.  Cheesy

I agree it is to much of hussle, but video was made in 2018, and Trezor was more expensive back then.

In this interesting experiment Votlog decided to make his own homemade Trezor Hardware wallet.
Trezor is fully open source so this is possible and doable.

Things he needed to get:
- Download repository from official Trezor github page: https://github.com/trezor
- PCBs and parts listed in electronics folder
- 0.96 OLED screen
- 3d print enclosure with data from case folder

Buttons are not great and his 3d print is not great but it is working.
You can try with other 3d STL files for making Trezor case from plastic or meta.
