Base building
Log from 3D Moving Machinery
More than three month ago I had a conversation with my son. He told me that he want to build a "drawing machine" essentially a pen plotter together with me. I started to design one. After a few conversation he told me that he wanted to build it from...

Design Considerations
Log from DFRobot Turtle Robot
If accuracy and precision are the goals, then most of the design decisions will rotate around the stepper motor (pun intended). The geared 28byj48 steppers (http://a.co/8bPbFhK) I've been using are incredibly cheap and work reasonably well, but...

Quantifying performance for the bigger 14-LED ring
Log from CIRTS - Configurable Infra-Red Tomography systems
Seeing images reconstructed from the new, larger ring was pretty cool. But did it offer improvements besides making pretty pictures? In this test, I try to quantify that.First, some background. With the first ring of sensors I built (8 LEDs, 8 PTs) I...

Log from Poor Man's Mini 3D Printer
I decided to work on the print bed today so I could measure and estimate just how big my print dimensions will be. I salvaged the plastic sheets from the inkjet printer I dissembled a few days ago. I will be replacing this with acrylic in the future...

Belt drive
Log from MultiBot CNC v2
It has been a long slow process, but I finally got my belt drive prototype finished. Modeling the gear was the tricky part, it took several tries and a lot of reading to finally work out how to make it fit the belt perfectly. I will...

A look at skin stimulus resolution
Log from Wearable Haptic Sensor
When I was in school (when tiny dinosaurs ruled the Earth) we did an experiment to map nerve endings on the skin. We had someone remove their shirt and lie down on a table, then we took 2 toothpicks and pressed against the skin of the back and asked...

Why?
Log from Feedbass! (microphone in loudspeaker)
I've been asked by @charleslinquist , why not add bass boost for that particular speaker+box with a filter network in front of the amplifier, instead of all this mess with microphone? Nice question. I actually have been doing that for a long time, but...

STL to kicad to gerber
Log from EOS RP repair
There was a guy who transferred a DXF file from fusion 360 to kicad, 4 years ago. It's now the File->import->Graphics dialog. Helas, these vector graphics formats are limited to sketches while the traces in the camera board are fusions...

Design
Log from Big roller based plotter/vinyl cutter
Frame The frame is mostly made from 700mm and 200mm 2020 aluminum profiles and various brackets. Then end plates where initially made with hand tools and a drill, but later versions are laser cut. This was still at the time when I tried to...

A basic script to monitor the controller input sent to the quadcopter by UDP
Log from Controlling a JJRC H37 Elfie quad from a PC
I'm in the process of making a small program to read the control input from a USB gamepad and send the commands to the quadcopter but first I wanted to make sure I got the UDP protocol right. Therefore, I wrote a small Python script that can be combined...

[X] No immediate leaks!
Log from Coaxial8or [gd0144]
[X] = Experiment / TestI wake up. It's 9am. I think "If I test the hotend now, I might be able to make it to the uni if things go wrong." It took 6 hours, with the first 3 hours just finding my seldom used soldering gear because the...

Log from Improve the Haber process
TL;DRI purchased and reverse engineered a cheap eBay ultrasonic power supply, to see if it held any value for the hobbyist.This first post explains the process of reverse engineering the (or any) board.A subsequent post will discuss the specifics of...

G Code
Log from 3D Printed PCB mill
So G Code is dumb, luckily FlatCAM outputs G Code that makes sense to me. Instead of having a whole line of commands, that need to be interpretted in a different order then the order recieved, it just sends one command at a time which is easy to interpret...

Magnetic Ball Joints
Log from Delta 3D Printer
One of the causes of slop in my printer linkages was the Traxxis ball joints. They have quite a lot of play unless they are pre-loaded. I worked around this by using elastic to pull the two arms together. This worked surprisingly well but showed slight...
