Agon Light?
Kastrup Sep 14,2022
Agon? is a modern, fully open-source, 8-bit microcomputer and microcontroller in one small, low-cost board. As a microcomputer, it is a standalone device that requires no host PC: it puts out its own video (VGA, various modes, 64 colors), audio (2 identical mono channels provided via a stereo audio port), accepts a PS/2 keyboard and has its own mass-storage in the form of a μSD card.As a microcontroller, it has a control port featuring SPI, I2C, 20 or more distinct GPIOs (including UART lines), ...

ATtiny45/85 Breakout Board With FabISP for use with Arduino projects
Pierce Sep 14,2022
This is a spinoff of my other board:"ATtiny45/85 Breakout Board for use with Arduino projects"https://www.pcbway.com/project/shareproject/ATtiny45_85_Breakout_Board_for_use_with_Arduino_projects.htmlI added the FabISP Circuit to my board so I could upload over usb instead of needing to use an AVR Programmer to flash the chip. Without the ATtiny45/85 IC installed this board would function as a FabISP and could program my other boards over the AVR headers.I made this breakout board for the AT...

Fall Detection client-server system with Machine Learning
Bandini Sep 12,2022
Falls could be dangerous in any situation but for certain working scenarios, consequences are definitely worst, therefore came the idea of developing a Machine Learning fall detection/report system. Each worker has a small TinyML device in charge of detecting falls with accelerometer data and reporting to a server through Bluetooth. The server is a Raspberry Pi running a Python script that scans specific BT announcements, parse fall information and store it into a SQL Lite database for reports a...

FOC controller with Arduino
ELECTRONOOBS Sep 12,2022
Watch Full TutorialToday we will take a look over what is FOC control, create an awesome PCB and control a triple phase brushless motor with it at very low speeds and precise movement. FOC is a very common and useful method of controlling brushless motors and is used a lot in robotics. I want to explain to you how it works, how the PCB is made and show you the code and an example for an open loop control and then a closed loop control using a magnetic encoder which is also very important. A...

Jam Electronic Timer (JET): Compact Edition
CHUNG Sep 12,2022
A version of the P8 Jam Timer (JETT) designed to have all electronics (except a single horn speaker) contained in the main enclosure.Hardware has been simplified somewhat, but still uses the same Arduino firmware as its predecessor. The audio amplifier in the original has been replaced by a TDA3116D breakout board with minor modifications:Remove and short C9Remove and short C10Connect Left Input to GND (performed on the PCB)Replace R2 with 75KReplace R3 with 47KRemove R1

Turning a 1980s typewriter into a Linux terminal
Artillect Sep 10,2022
From the late 1800s to the late 1900s, a typewriter was one of the best tools for writing documents. Sadly, they were largely rendered obsolete by the rise of home computers. I didn’t grow up using a typewriter, but a couple months ago I bought a Brother AX-25 electronic typewriter. It uses a daisy wheel (a spinning wheel with letters molded into it) and a motorized hammer to type text, rather than type bars (or strikers) like in a traditional typewriter. The sound it makes is unmatched eve...

Dedicated Control Board for Mobile Robots with Wheels
silicioslab Sep 09,2022
IntroductionFor a long time we developed several prototypes and teaching kits of mobile robots and we always used different modules to build them.Among these modules, we highlight: module to drive motors, module TP4056 to charge the project's batteries, an Arduino board and a shield for connecting the wires to the Arduino's digital inputs.This amount of modules often generates problems with bad connections and also makes connections more complex, with more wires. Also, they are not feasible to b...
