In May I already shared here that I worked on the BTClock (#175847). Together with another bitcoiner we designed a kit with a custom made PCB which you can order on the webshop, so you can build it yourself. To build it you do to order the ePaper displays and the ESP32 (Wemos S3 mini) on AliExpress.
On the wiki there is a step-by-step guide. Also there is a Telegram-group where users and builders can ask questions and ask/give support.

Nicely done. Any chance of worldwide shipping anytime soon?

I'm looking for a way to manage the shipping costs for outside the EU while keeping costs and customs forms the lowest. For the US it's coming soon at https://btc-hardware-solutions.square.site/
May I ask what country/continent you're from?

Can the clock accommodate seven (or eight 😅) digit prices? What would it look like?
reply
Sats per dollar fixes this
reply
Good point. But I'd say it fixes it partially. Ideally, I would still like to see dollars per BTC, and I was wondering if something clever happens when the number of digits expands.
reply
There are many possibilities, you can code one yourself. This I just implemented:
Other ways I could think of is writing it as 100K.

Very nice, thank you.

175€ lmao! You guys are crazy.
Stack sats, don't waste fiat on unnecessary things.
reply
It's €125 if you build it yourself. It is designed to be a fun and open-source DIY project by bitcoiners, for bitcoiners. Some people are not able or have the time to solder it themselves. Also I only accept sats as payment.
reply
175 or 125, DIY or not, doesn't matter, that was not my point
people should be stacking sats, not wasting money on expensive eletronic waste.
reply
This is getting off-topic but I disagree, people should indeed think about what they spend their money on and if you think this is not useful that's perfectly fine.
However, people should also spend their sats. Huge fan of this article which explains why.
Last but not least, the repairability of open source hardware projects is very high. If it breaks you can just replace one of the components to repair it cheaply or use the components in other projects. In both cases it doesn't become electronic waste as closed, proprietary stuff often does when it breaks.

So the BTClock give the data of block height, mined BTC and the likes right?
reply
Thats right! Here is a screenshot of the web-interface so you can see all the features:

Sats per byte & Mempool size would be killer additions
