Linus Akesson and friends have created the “Craft” demo – using an ATmega88 to generate 4 channels of 8-bit sound and 3D graphics. Timing is crucial: One display line takes 24 μs, and is followed by a 7.75 μs break called the horizontal blanking period. After 480 such lines, there’s a longer break (1428.75 μs, […]
The Noise Toy kit is fun to use, but if you’re like me – leaving that little “PROGRAM” port unused will drive you crazy. With little knowledge of AVR programming beyond some fun with Arduino, I taught myself how to upload and hack source code for it. Read on to see how the deed was […]
The Noise Toy kit by Loud Objects is an easy build that delivers some impressive bit-bleeping goodness. After some simple soldering, you’ve got an excellent little synth-noise generator that can double as a programmable experimenter’s board – great for those interested in microcontroller sound synthesis. Next week, we’ll go into more detail regarding such programming […]
Getting a computer to “talk” with a CMOS camera can be difficult, if not impossible, at times. The site has links to PDF files that contain the schematics and theory of operation. There is also a link containing all the code. It’s a nice solution to a common problem. The aim of this project is […]
Having the doorbell ring just when you fell asleep, after your all-night soldering frenzy, can be a real annoyance. This simple project will allow you to turn off the buzzer or bell for 10 hours, allowing for a nice long nap. – Link
Dane has another interesting project that asks the question “Can PWM from a simple micro-controller duplicate complex sounds?” The answer is yes, with surprising results. Wouldn’t it be sweet if you could have your micro play back complex things, over audio for an extremely low cost? Imagine replacing that one i/o line that used to […]
