4-Joint Integration Test
Log from Open-Source 6-Axis Robotic Arm
Time for a big update!Progress slowed a bit during summer months but a lot of big changes were made. This video shows 4 joints running simultaneously in something a lot closer to a "production" configuration than ever before. There's still plenty of...

Extruder for Prusa i3 MK3S
Details from Extruder for Prusa i3 MK3S
On the homepage of Slice Engineering [0], the manufacturer of the Mosquito hotend, I followed a link to a modified extruder for the Prusa i3 MK3S [1]. I had a quick look at it, but decided to improve my designing skills by creating a new extruder. In...

Copying this over to HaD to enter the 2017 contest. The main build log has thus far been over here:https://sites.google.com/site/dbtayl/blogRegarding how I've thought through the design ("Design Your Concept"), a lot of work has already gone into this....

New Custom Power Supply Build
Log from Open Sky Anchor WiFi Drone Brings The GIG
This project requires a highly reliable and relatively powerful power supply. It needs to operate in harsh conditions, handle near full load constantly and also have a built in backup in case of overheating or any other failure causing output to drop...

AL3050 LED Driver (for a torchlight)
Details from AL3050 LED Driver (for a torchlight)
CircuitThere isn't that much to say about the circuit itself as the AL3050 makes things so simple - I just followed the schematic provided in the datasheet . The AL3050 has an internal MOSFET and internal diode, so very few components are needed - an...

Salvaged Server PC
Details from Salvaged Server PC
Businesses are allowed to write off worn-out or obsolete equipment as a business loss, so they make less profit that can be taxed. Every year, tons of working IT equipment is scrapped after a few years service.My local museum is contractually obliged...

Designing a New Face
Log from reComputer 1000
Up to this point, everything had been kind of coming together without any sort of real plan. In fact, the cartridges had ended up taking more effort than anything on the deck had. But now it was time to get serious -- I had to design a faceplate...

Illumination
Log from Pi 5 Photo Booth
The current LED lighting setup is the 4th revision of what started as a $30 light ring from Amazon. Here’s the specs of what I’m using now: 4 high-CRI, super bright, reasonably priced ($3) Cree LEDsBrightness controlled through PWM by a GPIO output from...

Class D Subwoofer Amplifier Out of Scrap
Details from Class D Subwoofer Amplifier Out of Scrap
First Stage (Audio Modulator):This class D amplifier takes in a mono audio signal as the input to an lm393 comparator. The other input of the comparator is a 60Khz triangle wave using a 555 timer triangle wave generating circuit I pulled off the web....

Issue identified
Log from Semisolid Metal Printing
During the last test the metal filament kinked and the extruder clogged. I initially thought it was just due to the bend in the wire, but while the system was hot, the wire could spin freely, although it wouldn't budge when pushed in or pulled out. As...

A separate jamming issue
Log from Semisolid Metal Printing
Careful application of the X-Pando to the male threads, and replacement of the glycerol-borax flux with glycerol-zinc chloride flux removed the clogging issue at the nozzle, but now it appears that there is a new issue:As the wire approaches the heatbreak...

The clothes peg actuator
Details from The clothes peg actuator
Below is a description of the project following the design process step by step.High level designI needed a clamp with a stable closed position that I could control from a microcontroller. The clamp didn't need to be too strong so I decided to keep things...

Hackaservo.io
Log from GimbalBot
So I've come to the conclusion that my servos were designed to actuate smaller masses, and as such their control parameters aren't exactly suited for the larger than normal loads I'm putting on them. The vibration I'm seeing at the end of each stroke--particularly...

Controller (and conectivity)
Log from Stick / TIG converter
So I've started evaluating microcontrollers for the "brain" of this system. I think I've said before that I'll be using a PIC chip.The actual chip I'll use is still to be decided, but since I've got a few old chips laying about I'm going to start using...

Rev 1 post mortem
Log from Open Helmsman
Any complete redesign of a project needs a good understanding of what went right and wrong the first time. The board is above so I'll be working across the thing from left to right in the absence of any better ordering that comes to mind. While designing...
