hi im an relativly new in this comunity ( im aware of bitcoint one mouth ago )
since then i fascineted with bitcoin i will make some projects for this comunity
once a week i dewlop some device with pic microcontroler
i write directly in assembler and do not use any library in that way only my fault mey result in failure of device
main adventage is that i cen do many things in cheap microcontrolers
mometaly i learn ewriting i need for btc structure and i will post a dyi project for hardware wallet with wery low cost meybe less the 7 eur
:D:D
that is my target
alredy writed asm code for sha256 for microcontrolers now write code for other crypto function
i do a lot of big led displays,cotrolers for cooling and heating devices , sports scoreboard, a lot of devices for industry all on microcotrolers
all in assember and all my own pcb design more the 100 projects (but mosty on chep microcontrolers)
have experierience with pcb design i design pcbs for all my devices but this is mainly 2 layers
i do not know what is ur problem u do some patch on old devices please make me clear what wil be job to pcb dewelopwer
sorry for my bad english
