Tested the reworked protoboard tonight. Turns out I missed a line I was supposed to connect, so I had to put that in. After that I was able to test all the 5v and ground pins were working. To test the signal pins, I decided to wire it all up so far and...
While the eclectic nature of our shop has a certain charm, several areas beg for a bit of standardization. So from now on all new cordless tools will be DeWalt 20v lithium, and all new shop vacs will be Ridgid 14gallons. Obviously interchangeability...
What a hot day it is! Too hot to drive and ride and I am thinking of making a temperature measurement sensor. MLX90614 (a noncontact IR temperature sensor) on hand, let’s do it! Hardware &software in need Hardware in need Hardware ListFireBeetle ESP32...
Saturday, 08/07/2023, 09:37. Well, I just woke up and I'm already done with this project log, I will take a few days off and I'm not in the mood... Edit¹: Forget everything I said in this project log. Just now I understood what I was...
Introduction The typical machine vision systems I'm familiar with need to get the camera sensor data coded onto a protocol, transferred from the camera to the microchip, then decoded, and finally fed onto a pre-trained model which is solved by an IC,...
I had a few moments break yesterday from the rat race. I have made some good progress lately on the main DAQC python script. It is reliably pushing data to initialstate. (so much so I maxed out my free account) Tonight (friday cause i'm a geek) I am...
This project started as a way to understand how the 6502 processor works. Building an entire system with memory mapping and peripherals seemed daunting. There also didn't seem to be any good way to know what was going on inside the processor if something...
The SparkFun Qwiic MicroPressure Sensor is a miniature breakout equipped with Honeywell's 25 psi piezoresistive silicon pressure sensor. This MicroPressure Sensor offers a calibrated and compensated pressure sensing range of 60 mbar to 2.5 bar, easy...
Features It's a hybrid of a finger brake and a wiping bender. It uses holes for alignment rather than working off the edges of the sheet metal. Machine screws sandwich the upper hinge, the workpiece, and the finger. The position of the bend is determined...
In Part 2 of this mini magnum opus, we introduced the concepts of voltage (V), current (I), and resistance using a water analogy (we also extended our analogy to introduce the concept of charge). Now it’s time to delve a little deeper into the way in...
Still Thursday or whatever, 21:22, 08/12/2022Thursday, 16:41, 15/12/2022 - it took me an entire week to finish this incomplete project log.Also, I will skip the part were I fix grammar mistakes, this Project Log is just so long that it is lagging...
Thursday, 08:31, 24/08/2023 Well, morning. By the time that I actually start making the exo/endo-skeleton, it will be buried under 3983932382 project logs. ... But I think this is relevant, because I need to talk about Dielectric Elastomers...
Introduction This tutorial will teaches you how to build a weighing machine with the Arduino using a load cell and the HX711 amplifier. First, you’ll learn how to wire the load cell and the HX711 amplifier to the Arduino to build a Weighing Machine....
It is Wednesday my dudes, 15:56, 22/02/2023 Well, let's see if I can get this right this time. I will first try to make that dang equation work, and then I will try to see articles using actual heavy duty McKibben muscles and guess the dimensions...
******LATEST NEWS********7 September 2016: This weekend I ran a standing mile race here in Sweden with my old 170hp engine, I ran a personal best of 284.8km/h and I have a trick or two up my sleeve to tune the engine for next year so I can break the...
