I did had the PCBs here for some time (were on same order as my new #PICTIL PCBs). Here are some Photos of a assembled one:

The breakable mounting holes do break off very easy. One did break of during assembling. And I did forget to put the reset PIN on a Testpad to program the IC. so I did soldered a tiny wire directly to the pad. All other Pins needed for programming are accessible over the Pin headers.

The processor was sold as ATmega8L. But I am not sure what it is. A think it is some reused parts because the fuse settings did not had the default values and the labelling is in bad quality. The suspicious labelling:

But at least the one soldered does work fine till now.

Looks great. Where did you get those shady microcontrollers from? It really gives this project a kind of a punk feel. Do you plan to add the reset pad to the PCB design?

  Are you sure? yes | no

Thanks.

I did ordered them on aliexpress.

And yes a pad for the rest pin is already added in the PCB file.

  Are you sure? yes | no

ah great, looks like a mini comb crossed with a capacitor bank... great design!
