The purpose of the project is to design a balancing robot based on the STM32 MCU. On the web, you can find many guidelines on designing the balancing robots. Nevertheless, I always had a hard time finding clear and complete instructions. For example,...
Keyboard The keyboard is a PocketType miniature ortholinear 40% keyboard kit available from Mechboards - https://mechboards.co.uk with numbers and symbols accessed by layer keys. It is microswitch based and OK for thumb based typing...
This is a project for a small benchtop galvanostat - a device that can be used for direct current or pulsed current galvanic deposition of metals on small conductive objects. Essentially, it is a voltage-controlled current source (based on Howland current...
Overview My personal goal has been to use this project as a learning platform for myself. So far, I’ve been able to explore all sorts of software and hardware that I hadn’t worked with previously. I’ve been kid-in-a-candy-store, getting to...
A seismometer, is an instrument used to detect and record ground motion caused by seismic waves, such as those generated by earthquakes, volcanic eruptions, or other sources of ground vibration. Basically, the seismometer consists of two parts,...
The initial board The initial circuit was published bye "Mdog" and did exist into two versions "solo" and "4axis". Both of these boards rely on the Ti LMD1845 H bridge circuit. The LMD18245 is a full-bridge power amplifier with 2• DMOS Power Stage...
I picked up a vintage HP 1600A/1607A logic analyzer set over the weekend which was state of the art back in 1975. I thought I would see if I could at least get them running and functional and then maybe develop some interesting stunt! I was surprised...
Introduction The project involves designing a PCB based on the ESP-12S module to create a WiFi repeater capable of extending the range of WiFi signals. This repeater will amplify and rebroadcast existing WiFi signals, effectively extending the coverage...
Phase 1: My goal is to design five PCBs that include resistors, capacitors, active devices and various input and output components. These will mount on a laser cut wood base similar to the original design, but smaller. One of the issues...
Overall Details. Normally you have an off-grid system that can, if necessary, be powered by a battery charger from the power grid. If there is less sun in the winter transition periods, the battery voltage drops due to discharging during the shade periods. ...
Especifications Power supply redundancy. Critical functions can run even during multi-days power outagesAll devices (RPi, Critical Nodes, Modem, DVR) can be powered on/off remotely. Current and Voltage are measured and logued. 4G backup internet...
1. Design The golden traces correspond to those of the T-800 brain chip (bottom view). 2. Schematic (old school) The brain chip is a TLC555, which is responsible for the Terminator's eyes blinking in a fading manner. 3. PCB
Overview of RVECC: RVECC encoder has a 32-bit data input (din) and generates a 7-bit output syndrome (ecc_out). The 7-bit output syndrome is prepended to the data and sent through the channel. The output of the channel is sent to the RVECC Decoder. The...
How It Works I built a quick-and-dirty proof of concept Android messaging app with the help of the MIT App Inventor. This app can receive text messages, and take some actions based upon them. There is a "Make Me Funny" button that feeds the text of...
Status The prototype is under testing for edge cases. Specification USB PD+PPS with CV/CC mode, 3.3V to 20V @ 5A continuous. Actual voltage and current output depend on your charger. Improvement from version 1: Better ESD protectionAdded Constant...
