Everything is on a COB.
Log from Interdimensional Portal Gun
Broke down last week and got 3 10W COB LED chips. They were about $3 each and each one should provide 1100 lumens. I didn't get the driver, but they run on 9-11V @1A so it's conceivable I could PWM them with a ballast resistor....

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...

Log from Novena Laptop
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...

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...

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...

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...

Introduction + First Look at PCB
Log from HomeKit enabled Aquarium Lighting
Recently we bought a BiOrb Flow 15L aquarium for our two fish. It looks pretty sleek (as you can see in the picture that I grabbed from the internet) and has a built-in filter and white LED light, both powered from a single AC-AC adapter (that has two...

Power Supply Design
Log from Novasaur CP/M TTL Retrocomputer
The remaining instability in the Rev. 1 board is down to power issues. The power distribution was deliberately underspecified to highlight problem areas and test different designs. There are two main areas of concern: inductance and current consumption....

Passive Water Cooling
Log from Multitool 3D Printer - Blackbox
Passive water cooling was one of the innovations I brought in with the Blackbox. There are three reasons why I prefer water cooling: I had only good experiences with water cooling before, the Kraken Hotend which I used for a while never failed...

Version 0.3 is calm, cool, and collected
Log from Plasma Toroid (sky-guided PCB edition)
Revision 0.3 of the induction driver creates a plasma toroid that's stable and controllable, and does so without overheating. I'm closing in on a finalized version of the driver. Soon, both the induction coil and driver circuit will be unified into a...
