EC or not EC: that is the question
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
For some reason, EC probes are relatively expensive. In most cases they are more expensive than pH probes, which to me seem a lot harder to make. So, I decided to make my own EC probe, as you can see below:The contacts are gold plated Studex ear piercing...

A lot of googling to start.
Log from LPC Serial Port
The first thing I did was try and find a device that could do what I wanted. I found this https://www.digikey.com/product-detail/en/maxlinear-inc/XR28V382IL32-0A-EB/1016-1974-ND/4515332 which should be exactly what I need. Its too much of a device for...

Everybody loves benchmarks! The numbers are in!
Log from Bit-serial CPU based on crossbar switch
When calculations are done 1 bit at a time, one should probably not expect blazing speed. To measure the clock cycles per operations, I simply baked a 8-digit BCD counter into the system and increment it at each cycle, and reset to 0 at each...

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...

Pro Trinket and Pro Micro Compatibility
Log from Pro Trinket USB Keyboard
In preparation for the next logs I wanted to talk a bit about the pin compatibility between the Pro Trinket and the Pro Micro. The reason why I also want to integrate the Pro Micro is that it's more commonly available and cheaper.---------- more ----------The...

In The Digital Domain
Log from Reverse-Engineering the milight on-air protocol
I also wanted to sniff the communication between the micro controller and radio IC, but couldn't get the case of the remote control open. At the next opportunity I brought the Mi-Light Wi-Fi controller with me and got that open more or less easily:Inside...

What shall we wrap it all up in?
Log from Commercial home automation
Any enclosure needs to be easy to access yet provide enough space to get all of our cables in and out without being too big. A tough challenge!---------- more ----------Once our technology solution is chosen, we have to mount it, cable it, make it all...

LVDS - VESA / JEIDA
Log from LD320EUN 32" Display for RasPI
The LG display allow to select the LVDS mapping between JEIDA and VESA. I encountered such issue again and images were generated to help diagnose the issue.The original image is pass through the conversion mapping to obtain the VESA and JEIDA images.----------...

Using a Counter for the ISR
Log from Simple Concurrent Tones for the Arduino
Using a counter for the ISRI received a suggestion to use a counter and trip method for the Interrupt Service Routine (ISR). While is was not keen as the method (Direct Digital Synthesis) is pretty standard and gives the best long term accuracy. But...

Controlling a Seeed Motor Shield with an ATtiny85 and Shift Registers
Log from One-Tiny Bot
In addition to a handful of TV-B-Gone kits, the feeding frenzy at Radioshack also yielded a dozen SeeedStudio Motor Shield V2.0 boards for a few bucks a piece. They aren't ordinarily the easiest, cheapest, or anything close to the best way of driving...

Programming Toolchain
Log from MIKBUG on Multicomp
There are some options for assembling 6800 code today. Ideally, a cross assembler would be good from Windows. Herb Johnson has adapted William C Colley III's A68 6800 cross-assembler. The A68 assembler runs in DOSBOX under Microsoft Windows. Output Format...

Analogue Wind Vane With Auto Set Up
Log from Arduino GPRS IOT Weather Station
As the amazing online GPRS Weather Station project continues, we have yet another upgrade to the vast array of sensors with a professional analogue wind vane, kindly donated by Vector Instruments. This device will eventually be hooked into the new, upgraded,...

[E1][R][X] AirBerries: Learning a custom keyboard layout
Log from Tetent [gd0090]
So I've recently got a fully electrically and mechanically complete CAD model of Tetrinsic and was, once again, doing some research for Tetent, mainly because I don't like how this featureless flat face looks: It turns out that the eteeController...

Augumented Reality: A primer
Log from SonoSight: The AR glass for hearing impaired
Augumented Reality is all the rage today thanks to the constant battle between the giants Apple, Google and Microsoft. Despite each of them trying to come up with their own AR glasses along with startups like META there is still no wide market AR glass....
