Some Toner-Transfer PCB Highlights

Some recent highlights from my home-made circuit boards using the toner-transfer method.

0.5 mm FPC breakout board

Yes, I have been told that I am crazy before… Designed in KiCAD

0.5 mm pitch FPC breakout board – before etching

0.5 mm pitch FPC breakout board – half-way etched

0.5 mm pitch FPC breakout board – almost done

0.5 mm pitch FPC breakout board – soldered

 

TQFP32 controller board (student project)

This one is actually not my design and it was drawn in Altium.

433 MHz wireless sensor node

…another recent student project. Designed in KiCAD.

433 MHz wireless sensor node with Arduino nano – peeling off the paper

Soldering exercise for the MakerSpace

Designed in KiCAD.

SMD multivibrator with two blinking LEDs

 

IR remote control

Designed in KiCAD

Final assembly in the 3D-printed casing.
