MIDI-IR Build Tips

Look at this picture on my flickr site which gives a good picture of where everything goes.
The IR LED's, the battery holder, and the MIDI connectors all go on the BOTTOM of the PCB. Very important.
Solder the battery holder LAST. In order for it to fit flush against the PCB you may have to trim the leads of the 6-pin header and the button.
The IR LED's are the pinkish ones, the bi-color LED is the milky white one. They look similar so be careful.
For LED's I made up this rhyme: "Long is round, square is ground". That means the long lead goes in the round hole, and the short lead goes in the square hole. The square hole is also the flattened side of the LED, and since it is the cathode it is often attached to ground (or the lower voltage).
The big black diode is a Schottky and goes near the battery connectors and 78L05. The little red diode is a general purpose 1N4148 and goes near the MIDI connectors. Make sure you get the polarity right.
The socket is for the PIC 16F688 microcontroller. I think the software is pretty solid, but if you find a bug I can mail you a new PIC, as long as you put it in a socket.
The 1K resistor is a 1% resistor so it is blue. The rest are 5% resistors so they are brownish.
I changed the 500 ohm resistor to a 270 ohm resistor to make the LED's brighter. The board and schematic are still marked 500 ohm.
