Input Board

 

This is the input board, It has taken me a while to get all the things together which i needed to produce boards

I am using the "Pulsar PCB in a box" which is basically toner transfer from a laser printer, then transferred to the board using a laminator.

It has worked quite well, a couple of traces had to be repaired with a sharpie, but that worked fine.

First the board was designed on the computer.

then printed on special paper

the special paper and the board are run together through the laminator

then another stage with some green foil, which i also forgot to take a picture of.

Then the board was etched with ferric chloride.

The board is translucent white! it looks nice.

Holes were drilled on a Taig Mini lathe

And finally the parts were soldered in.

The LEDs were scavenged from a dead linksys router (for some reason LEDs in a bit of plastic cost almost 10 times as much as LEDs not in a bit of plastic)

All this board does is take the connections from the 13 pin guitar signal and MIDI in and route it to headers. the LEDs for the 13 pin will indicate the positive and negative power supply is working. the LED by the MIDI input is just a MIDI activity indicator.

The power for the 13 pin is needed because the Roland one i am using (and most other hex pickups as far as i know) has the preamp built right in , this power is usually provided by VG99 or whatever you are using the 13 pin system with.
