Motion Control
Log from Microwave Aluminium Printing
The hard work is done - we have successfully got the Aluminum to melt in our microwave kiln, and we have been able to cast objects from the molds that we designed. The system works - huzzah! Now, we must build a simple remote-controlled automation...

Pole
Log from Motorized Dual Color Zoom Backdrop
I simply used an 8 foot closet pole, the kind normally used in a closet to hang hangers on. It's a good diameter at 1.25 inch, relatively lightweight and quite stiff as it's thin steel. They do make a heavy duty version that is much heavier,...

Some adjustments
Log from Vending Machine for Birds
I reduced the sensitivity of the dispense sensor as it was triggering when a tiny piece of nut was dispensed. Now it dispenses more reliably, though sometimes 3-4 peanuts at a time. Also got a 20K mAh power bank to run the Pi camera - runs it for about...

Building a super cheap stereo camera
Log from Stereo Photonics
While there are plenty of commercial stereo cameras available they all tend to be a bit expensive. We needed a stereo camera, just to start experimenting with the algorithms needed for depth estimation, so we built a really cheap one using two old webcams....

IoP Satellite - pump head
Log from IoP water distribution
Here's what was supposed to be the initial concept for a plant automation system. A pump / control head is mounted to a reservoir with 1.5 .. 20 L volume. The head contains a small brushed motor peristaltic pump in a pipe clamp with vibration damping....

Log from Retro-futuristic automobile control panel
Greetings, dear Chinese hardware buyers,This update log can go straight to hackaday's chapter of biggest fails of the month.Two days ago I changed all the rear axle bearings because they made a horrible noise and they have not been replaced since around...

Physical Build details
Log from Captain Underpants Toilet
I am going to break up the project into three parts. Physical build, Arduino work bench sensors, and lastly integration of all the systems. For the Physical build I first needed to find a toilet to work with. I went to eBay, I found...

Cantenna: The Poor Mans' Directional Antenna
Log from CEMN - Community Engagement Mesh Network
Yagi or parabolic antennaes are the most effective at concentrating the power of the WiFi transmitter in a specific direction but they are complex to design and construct. In order to simplify the construction process and make it easy to construct locally,...

part 11: (attempted) bass-trapping, Blended Perception Curve
Log from DSP 01: hi-fi audio signal processor
in the previous update, i fretted about the 146Hz node in my listening room, and wondered if i could fix it. you can't just fix it by turning up the gain at 146Hz - it's like pouring sand into a black hole. the problem has to be fixed acoustically, so...

Stickvise Rules
