  • Camera and Image Processing Software
  • Log     from Portrait Plotter
  • So far my experiments had used image data produced by hand in Photoshop. The goal is to have this completely automated, so that a visitor has their picture taken by a webcam and gets a live preview as far as possible, and upon a button press the system...

  • Indicators
  • Log     from KAPCOM
  • I got the first of the outputs working. I can set an LED based on JSON from serial. It works fine manually, but with the Python script the Arduino doesn't like the JSON it sends. While trying to debug this, I discovered that the Arduino is sensitive...

  • Pipeline Overview
  • Log     from 100MHz TTL 6502
  • Let's now take a closer look at the pipeline in this design. The objective is to reduce the cycle-time while keeping the cycle-count fixed. The critical path in the CPU falls squarely on the ALU, and associated pre- and post-processing. Rather than cramming...

  • X11 Application Migration pt. 1
  • Log     from Metaverse Lab
  • I needed more than just having an SSH tunnel from within Janus. The ability to have remote X applications migrated into VR gives a metaverse developer much more power to access and create content without having to leave the client. I strongly believe...

  • Reverse Engineering the Screen
  • Log     from Bistable LCD e-Paper eReader
  • Origin I first saw this screen on the ZBD EPOP 900 electronic shelf label (ESL). Thought it is going to be fun just reverse engineer them, so I bought a few of them: PCB After I got them, the first thing I tried was powering them up. And... I got nothing....

  • Step 8. Tesla Coil & UV Lamp
  • Log     from UV Sanitizing Autonomous Robot
  • Tesla Coil A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. It is used to produce high-voltage, low-current, high frequency alternating-current electricity. Tesla experimented with a number...

  • Control Sub-System
  • Log     from Apollo Guidance Computer
  • I have drawn initial schematics for this sub-system, but have not started wiring it up.Here are design notes that help understand the schematics.Clock: At the heart of the Clock module is a 4 MHz crystal that is divided into four non-overlapping...

  • New Connector Masterboard
  • Log     from Seiko Robot Custom Controller
  • 11/5/14 With Aaron, we tried to trace the controller cables. I documented the wirewrap job that had been done, probably at Case, as well as the connectors. Then I removed the offending innards and placed them aside, including an obsolete sort of motherboard....

  • Transistor Placement
  • Log     from Voice Recognition Touch-Tone Phone
  • So that we have our pads/traces setup, the next question is how do we best connect our transistors ?For a refresher on transistors SparkFun has a pretty good tutorial, including amplifier applications, so here just the basics we need for this project.Also,...

  • Manual placement of 78 APA102-2020 chips
  • Log     from The Glowy Heart of Blink
  • Here’s a funny queston. How do you solder 78 separate APA102-2020 onto a board? Just in case it isn't clear, each of these has 8 pads (6 active) and each unit only 2mm on each side. These parts are TINY! I normally make SMT prototypes by dabbing the...

  • First design
  • Log     from VGA video generation card
  • Let's make a start with describing the design. Before I forget how everything is supposed to work. It's rather complicated. The schematic (at it's current state) can be found in the file section of this project. Note that most IC's are HC in the...
