Improvement of the EC sensor
Log from UltraTower
It is better to read the EC sensor log before reading this one. I wanted to test the stability and accuracy of the EC sensor! So I replaced the EC probe with a fixed resistor (to mimic the resistance of a solution). The EC probe was replaced...

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...

LISP/80
Log from Homebrew CP/M-computer powered by Arduino Nano
Launched on the "nanocomputer" LISP/80 interpreter version 1.1 from Thomas W. Yonkman: Here is a note about this interpreter in BYTE magazine:

Basic-80
Log from Hacking the 4952
So, I've gotten Microsoft Basic-80 running, but as I've not found the keyboard, serial, or disk I/O yet, all it can do is proudly proclaim that it has 32KB of free memory at it's disposal.

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...

CP/M-80 emulation under CP/M-86
Log from V20-MBC: a V20 (8088 + 8080) CPU homebrew computer
I've released a new SD image that adds in the drive F: of the CP/M-86 Disk Set a CP/M-80 emulator under CP/M-86 using the V20 8080 mode (VCPM15.CMD). In this way it is also possible run Catchum or send/receive a file with XMODEM: For more info see the...

CP/M-86 with AUTO-SWITCH to CP/M-80
Log from V20-MBC: a V20 (8088 + 8080) CPU homebrew computer
Thanks to Stephen Hunt, the author of the VCPM15 utlity, it is now possible to automatically execute either CP/M-86 or CP/M-80 programs without the need of the VCPM emulator program that he wrote back in the 80s. See how in the new paragraph: "CP/M-86...

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....

TekMate KH-80 Video
Log from TekMate KH-80
Quick little video on the TekMate KH-80 showing a turn on and shutdown as well as some specs of the machine.

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...

BeagleLogic Standalone schematic capture is now 80% completed. The following components/features have been placed:Logic Analyzer frontendOSD3358 supporting circuitGigabit PHY (Microchip KSZ9031) and Ethernet PortUSB PortsSPI FlashSD Card slot and eMMCRTCThe...

The below 80 % finished
Log from How to use an aerial 36 inches lens
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...
