My slim 2aa battery node tools

For (ftdi) programming @GertSanders very narrow and minimal switch node without removing the atmega I made a small board with pogo pins.
The processor needs to be connected on reset, tx, rx, vcc and gnd for FTDI programming. so only need those connections (pin 1,2,3,7,8)
soldering them neatly in the right position with the help of a few boards.
I used this type of the pogo pin (looks a little agressive :angry: ) but there are many variations. It depends on how you want to contact.the connection to ftdi header and a few components to have the circuit reset from the dtr pin. (10k resistor to Vcc and 100nF capacitor to dtr).
and that is the first victim board attached. I need at least one hand to press it against the pins therefore not really happy with the design.

@AWI : may you post the schematic diagram of your reset circuit ?
I got so many connection issue with my FTDI. I of course check internet but nothing is working correctly.Thanks !

@AWI no surprise. It's what I've done except for the capacitor on AREF pin but I'm pretty sure there is no link.
Thanks.Perhaps a problem due to my Mac. I don't know how I can check the connection and isolate the problem.

I'm pretty sure that a Mac and the DIP version of the atmega328 like each other. I have only used the DIP version and I also work on a Mac. -

I have only used the DIP version and I also work on a Mac.@GertSanders I tried today and now I can download sketch correctly. One strange thing is that I have to open the serial monitor to have the arduino working after the download ...
