USB Gameboy cartridge project

[Jose] thinks that the Little Sound DJ is too expensive and hard to find. Now he’s trying to build an inexpensive USB programmable GameBoy cartridge. Currently he’s working with a LPC2148 development board. It’s not quite clear where he’s going with this. He certainly wants to add USB programming, but it seems that he’s trying to hack a mp3 decoder in there as well. [update: yes, I know how to spell cartridge!]

Followup: Soldering How-To

The response to the soldering How-To was fantastic. You guys seem to want more and we’re looking forward to bringing you more How-Tos in the near future. If there’s a specific topic you’d like to see, let us know and I’ll see what we can do.

[justin] suggests picking up a flux pen with your next electronics order. I’ll probably take him up on that idea. [xrazorwirex] suggests using a pure form of alcohol like everclear for cleaning boards. I keep a few bottles of tape head cleaning solution – it won’t leave residue like rubbing alcohol and you don’t have to be 21 to buy it. [MattS] suggests cutting your leads and then soldering to prevent corrosion later on. This usually isn’t a problem for small projects, but it’s a good idea for anything that’ll see a less than ideal environment later on. [Josh Malone] is fond of his Hakko 936 soldering iron. I have to agree with everyone that a temperature controlled iron is the way to go. I was very happy with my Tenma which lasted well over 10 years. [David Moisan] suggests buying purpose made soldering sponges from MCM to preserve the plating on your soldering tip. Considering the varied contents of kitchen sponges, this is definitely a good idea. [Forrest M. Mims III] freaked me out a bit when he commented on the post – he notes that he taught his son to solder when he was 4 years old! I’m a bit more conservative, but lets be honest – I learned how to solder from his books when I was a kid.
