  • ST3Mbot
  • Details     from ST3Mbot
  • STEM Sussex Big Bang Fair requires loud, bright attractions to engage with the visiting students. ST3Mbot meets those needs. He started life as an old flip top bin, that had a nice Chrome lid (or head). I chopped the bin in half with a dremel, and welded...

  • Camera and Image Processing Software
  • Log     from Portrait Plotter
  • So far my experiments had used image data produced by hand in Photoshop. The goal is to have this completely automated, so that a visitor has their picture taken by a webcam and gets a live preview as far as possible, and upon a button press the system...

  • Force Gauge
  • Log     from RC Plane Force-Feedback System
  • The centerpiece of this project and the component that took the most time to develop is the force gauge. The basic idea of most force measurement is knowing the relationship between the displacement of an object to the force that caused that displacement...

  • WiFi Clock
  • Details     from WiFi Clock
  • It’s a glue up of a 3 x 2,5 inch by a 1/4” piece, with 1/4" square strip, to hide the end grain. Another row of 1/4 strip is used to make a housing for the connector and hide the connection to the brass frame. Then some holes and a coat of flat...

  • And the Answer Is...
  • Log     from Think-a-Tron 2020
  • The Hardware I did a fair amount of research before I decided to use QR codes to encode my answers. I discovered that there was a lot of activity around using the ESP32-CAM module to read QR codes.  The ESP32-CAM is a very small camera...

  • CO₂ Cubed!
  • Details     from CO₂ Cubed!
  • Ventilation & Carbon dioxide: Good ventilation is important for indoor air quality, especially for reducing the concentrations of pollutants and airborne viruses (looking at you, COVID-19!).  Measuring carbon dioxide (CO₂) can be a useful proxy...

  • [P] Concept prints and print settings
  • Log     from Tetrescent [gd0150]
  • [9 Sep 2023] The actual changes that I've implements aren't that numerous -- I plan to use a 2.0" transflective LCD positioned closer to the north edge, the Thumb Tetrinsic has been moved north to be the same disance from the edge as the left/rightmost...

  • 7404/14 - Not all inverters are the same.
  • Hacker page     by Dave Collins
  • The Problem: While debugging the HB6309 PCB REV1 I wanted to build a very stable oscillator I could drive the CPU and the Arduino with, I knocked together my standby: 1/2 of a 74HC00 and a 1K resistor and crystal with fairly mediocre results: This is...

  • Arduino Spider robot (Quadruped)
  • Details     from Arduino Spider robot (Quadruped)
  • Hey guys! Here is a new tutorial to guide you step by step while making this kind of super amazing electronic projects which is the "Crawler robot" known also as "Spider Robot" ou a "Quadruped robot". Since every body noticed the high speed evolution...

  • Physics Model
  • Log     from 2021 HDP Dream Team: EJA
  • To predict how our robot may perform in the real environment, a physics model would be useful to understand the forces at play. The calculated results serve as data points that can be verified experimentally to see how they differ in the real world....

  • Pulse Generation Circuits
  • Log     from DC Current Transformer
  • In the last posts we saw how a fluxgate works in simulation.  Simulations are all good when you can just add a pulsed voltage source - everything is perfect.  In the real world, we have some challenges:1) We need very low DC offset to avoid...
