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...
For those wondering how we assembled the boards, we compiled a video of all the different steps. We started off with prototype machinery (Mechatronika M10 and Mechatronika MX70), manual solder paste dispensing using a eC-Stencil-Mate and reflowing...
The rest of the boards just came:I think I will connect them together through wire-wrapped "motherboard" (lets call it "NEDONAND-10" ; )All of these NEDONAND components could be tested one by one using PIC microcontroller (connected to PC through RS-232)...
I'm in the process of porting over the Google Chromium OS code into a standalone library for USB Power Delivery. I started with just the FUSB302-specific code. You find the github repo here. The example explains how to connect this breakout board to...
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...
The sun tracking system consists of: 1. Two roller shutter/awning motors: These motors are industrial, easy to purchase, cheap, and with a high torque (10Nm being the lowest). Average price of each motor around 30€...
Revisiting the RAM signature stamping knowing what I know now, I can better see what's going on and record that knowledge. The RAM stamping routine now looks like this:F723 ; stamp 'ram valid signature' on RAM page 0 and 3 F723 stampRAMsignature_F723:...
In a previous log I said, "I'm not going to overthink this. Random selection from the chess openings is working.". Well I lied. I am going to overthink this. (Well at least think it.) Something I should have done when working on the opening moves was...
An article recently published on MOONGIFT, a Japanese developer site, has showcased RasDash! The article is entirely in Japanese and Google Translate won't accept the URL as it has special characters but YANDEX does. Below are some links and a basic...
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...
