We have just published a tutorial on how to properly setup and calibrate your Incremental Quadrature Encoders with SOLO to control the Torque, Speed and Position of your BLDC, PMSM or Coreless Brushless EC Motors. https://www.solomotorcontrollers.com/how-to-connect-quadrature-incremental-encoder-to-solo/...
The rebalance is still progressing. It's particularly slower because I also changed the failure domain on my cephfs EC pool from OSD to HOST which increased the number of PGs that needed to be remapped. Aside from that, the rate of progression...
To build a tower you will need to print the 3D parts shown on the left of the image. The "Sensors float" part is optional, print it if you want to use the pH and EC sensors. You will need 12 times the part: "Basket". You can download the files...

This idea was born when i saw this project years ago: https://hackaday.io/project/170961-resistor-color-code-clock-v10 NOTE: There is a bug showing resistor values under 100 since gold nor silver can be displayed. AND the multiplier seems to be...
From OpenCores PDP-8 page: Features In this FPGA implementation, the PDP-8 CPU can be configured to emulate the instruction execution of a PDP-8 (Straight-8), PDP-8/S, PDP-8/S, PDP-8/I, PDP-8/L, PDP-8/E/F/M, PDP-8/A, HD-6100, or a HD-6120. The...
They say that a picture is worth a thousand words, so: As you can see, THE NEW PEAK DETECT CIRCUIT WORKS! It's always nice to see something work in real life versus simulation. It's kind of hard to see exactly how close the peak detect output...
Just a quick picture to show off the tremendous root growth. The plants are about 5 weeks old except the one on the bottom of the frame which is six weeks old. Click on the picture and zoom in to get a good view of how dense the roots are.You...
Redford did a whole lotta work reverse engineering the BIOS code and figured out that most of the interesting stuff (password check, challenge/response for lost password) is actually done by something off the main x86 processor. We figured out that it's...
I was looking for a way to make the Excel Paper Model for the Z30 calculate the stepping points so it would be a complete model of the machine. The example shown below is for a rotor with a Ring Setting of 4, the 1 mark on the ring is set to the 4 position...
I have squeezed some simple instructions into a 16-byte ROM that writes 0x04 into the I/O address 0x00, and repeats (http://www.homebrew8088.com/):A: MOV AL, 04 OUT 00, AL JMP AThis is then converted into machine code (https://defuse.ca/online-x86-assembler.htm),...
In this project, instead of using a standard embedded processor and programming it to execute 3 tasks at hand (parsing HEX character stream, generating HEX character stream, and writing character stream to video RAM driving VGA), I created 3 independent...
I'm currently working on the Python software to interface with the EC/pH/Control board and also developing the web interface. The web interface, shown below, uses webiopi. It's fairly programmer friendly and so far has been reliable. The...
One Bit CPUs There are a couple of one bit CPUs on the Internet. I have start with the MC14500B chip. This chip was used many years ago for PLCs but the documentation is still available: http://tinymicros.com/mediawiki/images/e/ec/MC14500B_Handbook.pdf...
Here is the plan. I plan to turn this into this And here is the design block diagram. There will be 3 sensor node and a nutrient control system. All of them is developed with ESP8266 board (either WeMos D1 mini or NodeMCU). I plan to use Blynk IoT...
