In the original configuration, the airswimmer is propelled by the tail fin, which can be flapped left-to-right using the remote. The whole fish can also be tilted up or down by moving the gondola, which holds the battery and receiver, forward and back...
I've done this project twice. The first keyboard completely died shortly after I made my spare. Unfortunately the new one's USB hub is less reliable. The keyboard doesn't get activated soon enough to send keypresses during booting... I've been...
IntroductionVaporization is done by off-the-shelf ultrasonic atomizers, either really cheap ones (the black ones in the picture below, 2.50 $ each) or some more rigid ones (the silver one, a Fogstar 300, 290 € each), air is moved by an array of...
I've been busy with other projects, summer and the day job, but here's an update on the Pinstax. After weeks of perking this project through my brain, I enjoyed some frenzied productivity as ideas came to 3D printed reality. One of the problems...
Design choices:-ATmega 328 μController + DS1307-Supertex HV5812-IN-12 Russian Nixie Tubes-Use of reed switches to allow control while not having buttons showing
The idea behind this project was for my sons birthday party. He wanted a robot themed party, so I figured this would be the easiest to build. Similar to the commercial claw machines, the idea is to grab a toy and successfully get it transferred over...
This HOW-TO explains a quick and easy way to speed up NetBSD pkgsrc compiling on retrocomputers. It was written because there are altogether too many distcc how-tos which are complex, require special build environments or make assumptions without explaining...
4 voice (Bass drum, snare drum, open hat, closed hat) analog drum machine originally controlled from an Android device via IOIO (microcontroller) thanks to MackeMints (http://projects.hackaday.com/hacker/812) pro programming skillz.Version 2 is under...
The local club needed another scoring box, and the things cost a fortune. So naturally I thought, "Hey, I can totally build one of those!". And I did, sort of.First attempt was way too elaborate. it was a whole enclosure with EL panels...
For my GPSDO project I’ve opted for a Piezo 2940210 VCOCXO at 10 Mhz. There is a dearth of information on this particular module available online.(A notation notation: I utilize “E” notation to indicate orders of magnitude; thus 1.5E-6...
Pretty neat and cheap project I put together last night with basic components. They call for an LM348, but I used an LM324 and it works fine. I enclosed it with some thin oak I had leftover from a different project and bent copper wire in the shape of...
After gutting a car for the engine in an auto shop class, I found myself with a trove of interesting spare parts. I recycled the car's RPM gauge into a clock that sweeps out the seconds from 1 to 60 and displays a digital time readout. A Basic Stamp...
[Intro] {Updated 2/25/2016}VisualK-OS collectively refers my custom-built system of lighting devices, intended for use with my band's (Saturn's Iris) live shows. To date, the system consists of: The main control center, Thor and the Flood Bank Array...
The point of this project is to make a CMYK compatible 3D print method that only uses one filament to extrude with dyes. That way we can replace the current method of using 3 filaments. This will reduce the physical footprint, lower power usage, and...
Think of this tablet as not as some toy, but as a computer in whole. This Tablet is designed to be Modular by using USB as the main communications line. Though it is a modified version of USB so that way any one attachable card can be a power source,...
