LED Matrix part three






Another five boards etched. The circuit is printed onto the transfer sheet on a laser printer. The transfer is then ironed onto a sheet of copper backed board. After sawing into five individual boards we drop it all in the etching fluid for a half hour. The boards then need scrubbing (to remove the ink) and drilling.

We've soldered a bunch of the LEDs to wires in readiness for when we get drilling and soldering tomorrow.
