Few days ago I found a perfect open source alternative for expensive overpriced blockclock by coinkite(coldcard.
I am already boycotting all NVK-coldcard products and I hope he won't be angry and pissed (again) because someone made cheaper and better product (again) and made it open source.
Let me present you BTClock , made by Djuri B. from Netherlands.
Open-source block-shaped clock that is showing Bitcoin related information including Block height, Moscow Time (Sats per Dollar), Price, Time, Halving Countdown.
You can currently purchase BTClock fully assembled and tested for €190, or you can purchase individual parts and build it yourself.
It is using genius design with multiple small eInk displays mounted on top of PCB.
