good luck to your build. my camera will arrive monday already.

when i bought my equipment the hammer pins were sold out. therefore i had to buy the normal pins. i thought it would be easy to solder but it was not.

i started the project last year but i messed up all connector holes with solder lead. all connector holes were filled.

i even tried to convert the pi into a trezor wallet using opentrezor. when you do that you have to connect some pins with each other which makes soldering even harder. i am glad i did not do it and continued to work on the seed signer. there is not even a comparison...

yesterday i bought a new solder iron with a smaller tip, the only one available here at walmart and melted the lead out of the holes. it took me almost two hours because the tip is still too wide.. some holes were still blocked. finally i got the row of pins attached to the pi. some pins looked not soldered, some were clearly connected with soldering lead. when i tried the seadsigner out it did not come up. i had to go back to soldering (i kept the iron warm lol) and put more solder lead on the visibly disconnected pins.

then the pi came up and i could play around with seeds. suddenly it had a malfunction. i thought it was a bug but it turned out that it was a loose contact. i had to solder again. after that it did not come up any more. i had to solder for three more rounds and then it worked flawlessly. i have tried it out yesterday and today at least twice every hour and it had no more loose contacts. i even pushed it and tested it. all good.

you can be glad that you bought the hammer pins. after the connection with the display everything was easy and straightforward.
