The first step is to remove the existing W25Q128 flash device and replace it with some pin header to connect up a custom board. The 1.27mm pitch SOIC-8 package is pretty easy to remove. First start by cutting each of the eight pins with a...
This is the "classic" MK-52 speed test adapted from Dr.Shelest book.On the actual ESP32 hardware, it executes about 175 times faster. Actually, the processor speed is even faster, but the Resurrect updates the screen and checks for the STOP button 3...
Date: 14 / 8 / 2019 - 17 / 8 / 2019 Testing for capacitive sensing, LED strip and dc motor. Used random jumper wire and breadboard •Touch on the copper tape to activate capacitive sensor. •Test on two LED, placed LED with the L298N....
Demo Background I am electrical engineer by trade, but in my spare time I like to make custom toys for my kids, particularly my son Ethan. Ethan has autism and sensory needs, which make most store-bought toys challenging for him to play with appropriately....
To build the Bell & Howell digital multimeter based digital dice tower, you first need to get a Bell & Howell IMD 202-2 Digital Multimeter. These were originally kits that were assembled as part of the Bell & Howell electronics curriculum back in the...
On Monday, December 4th, we'll be at Vancouver Hack Space to fix some LipSyncs. We've held a number of buildathons over the past year at schools, at corporate team-building events, and in makerspaces. Some of the LipSyncs built at these events need a...
Well, I lied, because projects like this one are never actually finished. But let's say I'm not going to do any major rework from now. It took one more board revision and a little bit of coding to come up with final hardwareIn the meantime, I made some...
In another page, I described my adventures converting an Ubuntu DEB package to an RPM package. This provided me with a native toolchain for my Linux workstation. I wished though that there was a solution that would allow far more Linux users, no matter...
Arduino compatible Electronic Load 19V/5A/15W This the second revision of my electronic load. It is intended for testing DC power supplies, solar panels and battery capacity. It is special because the hardware and software is open source, it is Arduino...
Modified from James Bruton's sketch example. This sketch uses the serial connection to listen for servo addresses 100 through 115, then activate, pause, and return each servo called.The Unreal Engine app only has to send the address followed by a newline.This...
Working on a flow sensor test setup the breadboard suddenly exploded! And I though blue smoke was the worst that could occur.. ---------- more ----------Yesterday I made a great step forward testing the flow sensor. I made a simple breadboard setup to...
Steps: 1. Solder the pin2 with pin6. 2. Connect the pin6 to pin7 with a 1M resistor. 3. Follow the steps above to make 2 chip sets. 4. Pin4 and 5 of the 1st chip are correspond to the pin4 and 5 of the 2nd chip. 5. Connect the pin5 and pin6 of the...
Hardware hackers love their test equipment. There are entire forums dedicated to talking about multimeters, oscilloscopes, signal generators, and other common bench tools. At times it seems we spend more time talking about our tools than actually using...
