I came up with a nice (from my own standpoint) circuit arrange that tester each and every pin of my Arduino-compatible board:- Pins 0 and 1 = Serial communication with a PC, through the "Serial.print()" command- Pins 2 and 3= an LED connected between...
SolidCore CoreXY CAD Design In Fusion 360 All Metal Parts Our long term goal is to is to build a modular platform, not just a printer. Think of it as an ecosystem of parts that can be arranged in different configurations and adapted for unique applications....

This project is the continuation of this link Will we run out of water? There is water almost everywhere on earth but when we talk about fresh water, there is only 2.5% on our planet. Too many people on this planet do not have access to potable water....
Background If you have been following Hackaday for a while, you will have seen on numerous occasions the KENBAK-1, regarded by many as the first commercial personal computer. Ten years ago Mark Wilson introduced KENBAK-uino, a reproduction...
While reconfiguring my NAS setup made of a ReadyNAS 104 and a ICY BOX IB-RD3640SU3, I tried to connect the external bay to my laptop to access the drives. Only a single drive was accessible when configured as JBOD. With the RAID enable, the bay register...
This project began with a request from the Incredible AquaGarden, who were busy building an aquaponics system as part of their project located next to the high school in Todmorden, UK. After researching the subject I advised that the available...
PROJECT VIDEOHARDWAREHow to combine two 8-bit PWM output into one 16-bit DAC?Single PWM output can use one output pin to generate analog signals with 8-bit resolution (as we learned in LAB2). However, we can simply create another analog signal via another...

I plan on using this bus as the backplane for supporting R&D for my Kestrel Computer Project. Signals are as follows:SYSCON Signals.50MHZ. A 50MHz reference clock generated by the backplane. NOTE: This doesn't mean that the bus has to run at 50MHz; you're...
Counting the GPIOs... With the intention of using the Raspberry Pico micro controller, I needed to understand how many GPIOs would be required to carry all of the necessary signals: 16 X Address Lines8 X Data LinesMREQ signalWR signalRD signal....
The work by others to port Arduino BASIC to the Smart Response-XE device was of interest, but I wanted a few enhancements to extend battery life (auto shutdown) and I wanted an easier way to do math on the console rather than typing "PRINT" everytime...
Control the classic General Instrument SP0256-AL2 speech chip and AY-3-8910 sound generator with a Raspberry Pi and this Python library. The SP0256-AL2 was originally available in the early 1980s in speech add-ons for the VIC-20, Atari 8-bit computers,...

Blinking LEDs, what can be easier, right? For a recent project I needed to multiplex 2 sets of 6 LED each. The circuit schematic has the LEDs driven by 6 pins on an Arduino plus two pins to activate one bank or the other. LEDs are these ones from LCSC....
