fabISP
The FabISP is an in-system programmer for AVR microcontrollers, designed for production within a FabLab.
We will use it in order to program the microcontrollers on the boards that we build.
We mill the circuit board on a Roland Modela Milling Machine
Once ready the board, I tried the various components to be welded:1 ATTiny 44 microcontroller
1 Capacitor 1uF, 2 Capacitor 10 pF, 2 Resistor 100 ohm, 1 Resistor 499 ohm, 1 Resistor 1K ohm, 1 Resistor 10k, one 6 pin header, 1 USB connector, 2 jumpers - 0 ohm resistors, 1 Cystal 20MHz, two Zener Diode 3.3 V, one usb mini cable, one ribbon cable, two 6 pin connector.
I had already welded before, but never so small components and at first I had some difficulties.
After having made some small mistakes I managed to complete the job.
Unbelievable but it works!!!
