pH and EC Circuits Tested
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
I just got the pH portion of the circuit working. There actually wasn't anything wrong with the circuit. It turns out that the probe that I was initially was using was bad. I tried a different brand and it worked perfectly. The working probe is listed...

Orchestra 80/85 Support
Log from TRS-80 Model 1 on a PIC32
The PWM has been in-place for quite some time (and is used for the 'cassette sound' feature that many games use), but I had never gotten around to implementing the Orchestra 80 support, even though it should be simple. Part of the reason was that...

Cyrillic alphabets in Terminal-BASIC output
Log from Terminal-BASIC
My friend Dylan Brophy inspired me to investigate the ability to output the cyrillic text using different output devices, supported by Terminal-BASIC. 1. Using symbols others then capital latin in identifiers not possible and unnecessary. 2. USART output....

Getting somewhere, 80% efficiency =)
Log from Breadboard power supply
I've been having trouble getting by "big-ass" mosfet, from an old class D amplifier project I'd been working on, working with the 3.3V output from the teensy (gate charge, threshold voltage etc.).Eventually I managed to put together a circuit with a...

The donor for the below has been a leather couch cushion, in very good shape, given to me years ago by a neighbor, it's nearly exactly what was needed.I had tu unsew it all to do my patron, and with the help of Sabrina, my colleague from the "design...

80 Column Text
Log from Novasaur CP/M TTL Retrocomputer
The testing phase has been using NOR flash memory. The fastest version is rated at 70ns, and although much better performance was observed, it will not support a dot clock above 25MHz. The final design will use the 55ns rated Atmel AT27C020. A similar...

AC Analysis
Log from Total Harmonic Destruction: Distortion FX
Some quick and dirty AC analysis using LTSpice shows some interesting problems:[Figure 1: Three AC passes using LTspice showing both phase and amplitude. The blend control has been set at low, mid, and high illustrating the change between the diode saturation...

Re-UD-80 in case
Log from Re-UD-80 - a larger display for Epson PX-4 / PX-8
Here the first attempt for a case for the UD-80 replica. More tuning required. Here a STAT A:*.* and STAT C:*.* on the external display. The board inside the case. No internal mounting is required, the front and back panel keep the board in place when...

Install AC
Log from Big Old Bus RV Conversion
Bought a new window unit to cool the oven/bus had to remove entire window to install. I also added a 2x2 across the top of the ac for support as there is no window to pull down and seal it. I used parts of the window i took out to make the upper window....

AC Servo buying for test
Log from Open Source Cinema Robot
2020.3.20 // AC Servo buying for test update.As I was modeling, I was trying to figure out which motor would fit my robot, and I decided that AC servo motors were suitable, and I found a servo motor store in 'Aliexpress', a Chinese shopping mall that...

Colour 80-column text, finally!
Log from Neotron Pico
I've spent some time thinking about how to improve the PIO program that runs our Super VGA out. Currently it requires one 16-bit value per pixel, delivered from one of two ping-pong buffers each 1280 bytes long. Loading these buffers with RGB pixels...
