I'm having some trouble keeping the kit in stock since the Nut and Volts article came out. If I'm out of stock, try ordering from the Nuts and Volts store at
Thank you for your patience and understanding!
I assembled the first board, using a Zero Insertion Force (ZIF) socket for the microcontroller. The socket has a lever to release the microcontroller so it can be inserted and removed without any force. This allows it to be removed a lot easier for programming.
I adjusted the code for changes in the pin assignments and got the new clock working, except the alarm sounds strange. I suspect it’s a software issue of some sort, but will have to troubleshoot it later.
I mounted the board in a frame and installed some switches to aide in troubleshooting and code development.
