I've been into electric scooters for a long time. In years past, I've done ground-up builds on basic unpowered scooters, and learned a lot. This time, I wanted to see what the off-the-shelf electric machines were like, and I'm keen to find out how far...
For some more details, please visit the GitHub page of this project. Explanation of Front PanelSome YouTube Videos Description of the Microtronic, its CPU and Machine LanguageI was asked to provide some more details about the Microtronic and its machine...
Operation is simple, the user connects the phone to the GPS with Bluetooth. It connects to the GPS map. He writes his destination on the GPS OsmAnd application. Then the GPS shows him his way through the LEDs. Here below are the GPS indications: In this...
BOM available at https://wtfamps.files.wordpress.com/2016/05/muchedumbre-bom.pdf Notes on specific partsCAPSThe input coupling capacitor (.33uF) can be much smaller without sacrificing bass. The input impedance will be approximately the grid leak resistor...
So if we’re going to design and build a tube headphone amplifier that will work reasonably well with a variety of models, what should we consider?Damping factorProperly loading the tubesSufficient listening levelsFrequency ResponseSimplicityDamping FactorDamping...
Making your own PCBs is a lot easier than I imagined. Way back in the 80's I gave it a try. It involved marker pens transfer stencils and a whole lot of frustration. I recently got back into hobby electronics and with the aid of computers I have found...
The idea was to have a clock that does everything. The 3 main things I want to integrate in this project are: 1) Connect the clock to a bed shaker so my alarm clock can wake me up discretely without waking up my roommate, but also retain the ability...
In an ideal world, all clocks should synchronize with the network and deal with daylight saving hell automatically. Not only that, they should run for at least a year on a single AA battery and cost around the same price as current clocks.In this project,...
Conway's Game of LifeThis project implements well known Conway's Game of Life.Note that this implementation uses Periodic Boundary Conditions to simulate a field of an infinite size, i.e. each boundary is connected to the opposite boundary. This makes...
As my pint of commercial etchant reached the end of its useful life I began to wonder if I could make my own. The commercial stuff works well enough, but it costs an arm and a leg. I paid $20 for 500 ml (that's about pint for you non metric folks). Plus...
This project was created for a hackathon I participated in this weekend, but the hardware judging was removed so I thought the best place to put this is on here. Those software types didn't understand what I was doing anyway, to be fair. So now to get...
My finished product, a custom charging station for all of my power tools, based off of Snap-On's powerbank design.The whole box - finished product.Here is the basis of the project, a Harbor Freight 7 drawer 18" side cabinet, which I plan to attach to...
Capacitors are wonderful things - They allow the release of energy at tremendous rates allowing for endless entertainment with rail-guns, spark-gaps and all sorts of pulsed power applications. Batteries, specifically high power lithium variants, offer...
This is my very first development board project. After shrinking about 15k worth of equipment to a custom board the size of a credit card that can read your muscle signals, to winning TechCrunch Disrupt's 2015 Hackathon with an IoT device that tells...
Game programming is hard. Sure, you can easily throw together something in RPGMaker, RenPy or Unity3D, and it's great -- but you don't actually know how it works inside. There is a certain skill required to go from scratch, write your own main loop,...
