Just a quick experiment to show that the NESpad library I wrote for the Arduino microcontroller actually works. An NES Advantage joystick acts as a mini MIDI drum pad.
I wrote this library, called NESpad, for anyone who wants to interface an NES game pad with the Arduino microcontroller. I also made an SNES library (SNESpad), but I haven’t tested it with an actual SNES joystick.
Joysticks 101. Basically, we’ve got two types of joysticks: analog and digital. You’ve probably used both kinds. The buttons work pretty much the same on either kind – you either click it or you don’t – but the actual “stick” part is what makes them different. This post starts out with some basic joystick info and then some info about how you can use a joystick with a microcontroller.
A while back, I converted my 1994 Ford E-350 van to run on vegetable oil. I never took really good notes on what I did to convert the van, but I had all kinds of scribble-sketches hanging around all the time. Some of them are here.
My stylish project amp, in all its monophonic glory…
I’ve been trying to make music and noise from electronic gadgets and components. I wanted to make an amplifier that I could accidentally fry and not be upset about, so I made this one from the “Hit Guitar” that I found at Savers.
I tried to make a time machine using an AVR Tiny13 and a peanut butter jar. Okay, so maybe it’s not really a time machine, but it’s definitely a kind of trippy time-manipulator ala Doc Edgerton’s stroboscope experiments. Either way, it works and it’s pretty cool.
I have a few bicycles but these are the cooler ones. Continue reading “My Bicycles”
Back when I had my SV, I got a nail in my tire and I documented the process of getting it fixed so I could remember what I did the next time. This info could help you out, but obviously I’m not Suzuki so don’t come looking for me if your wheel falls off.

motd stands for “message of the day” and it’s the message that you see when you login to a unix-like system via ssh, telnet, the console, etc. Some people like to put cute sayings or “welcome” messages, but if I’m setting up a server for someone else, I generally want to put a less friendly motd in place.
This is a list of different ways to determine exposure times for your pinhole cameras
Okay, so you’ve built a pinhole camera and put some photographic paper or film inside. You’ve pointed the camera at your subject. Your finger is poised over the start button of your stopwatch. Now you need to know how long to leave the shutter open. This page contains a list of all the methods I know for calculating the exposure time. Choose the one you like best.
