The issue was a dead left speaker. Everything else was fine. Curiously, it got back to life after poking on the speaker wires. But it died again after a few hours of use. From this behavior, I assumed that the speaker itself was not the problem. Instead,...
There are four main components:1. The control board (that I'm making myself)2. A Tamiya tank chassis and gearbox3. A raspberry Pi with web server and fcgi API1. The control boardGoing on Version 7 (Minified3).MCU used is AT32UC3L0.Using separate battery...
I will use mini geared motors to actuate each one of the fingers individually and 2 of the motors to actuate the thumb and perform the thumb roll. I think with an automated thumb roll the InoDex prosthetic hand will be able to better simulate the human...
The circuit is very simple and it only consists of few components. For the regulated output to the sensors we have the LM317 adjustable voltage regulator, we have two 1N4007 diodes to prevent any reverse current flow in the event of a power loss, a 1k...
This 5-bar robot was designed with modularity in mind, so that not only you can make different components for the robot with relative ease, but also to easily visualize the changes on its task-space based on its current geometry. You can change the length...
The idea is quite simple: Stick some resistive wire under the build plate and tap into the 19V power supply of the Cetus to heat it up. I started by drawing some guide lines on the under side of the Cetus' build plate: I then covered everything except...
Notice: this project's name has been changed from "Tyfone" to "TyTelli" to avoid confusion with Tyfone Inc.Note that in the video TYOS 0.1.0 is used. Many, many new features have been added since then.HardwareThe TyTelli is made up of a few basic components:The...
I wanted to make a portable outdoor sound system that actually sounded good, and could be heard.I didn’t think this was much of a hack, I am just connecting off the shelf stuff, but a friend said I should send it to hack-a-day. I go camping(if you can...
Here is a diagram of the first version of my switch. I used a simple arduino relay module as the relay. This worked in testing but once I tried with with my vacuum it failed. I didn't take into account how much amperage the vacuum...
A Bit Pushy is Pantri's first device! It's a cool little button that works with the Pantri API. Why would you want to have one? You'll end up with a swanky button that you can press to connect to the Pantri service where you track & re-order grocery...
The main system is run on a Raspberry Pi 3b, which displays on a 15" LCD salvaged from an old laptop and run through an HDMI driver board. All components are mounted into a modified aluminum briefcase, which contains a weirdly-practical custom 2 layer...
I've been a fan of Apple's hardware since the early 2000's when they first introduced OS X. I had enough of Windows, its inferior architecture, and poor stability. OS X was stable, fast, and under the hood was Unix. The PowerBooks were...
Hackaday.io is all (mostly?) about sharing projects, so a key aspect should be how to create a project. I've made a couple but only rarely, so i forget the process. Looking around, about the only HELP available is this thing called Everything...
The mask is controlled by Arduino Lilypad board with FlashForth system installed on it. FlashForth has prebuilt firmwares for Arduino boards with ATmega328P running at 16 MHz. In the LilyPad board ATmega runs at 8 MHz. I tried to build FlashForth...
The process involves removing the A4988 IC from the board (either by severing the connection closest to the chip or using hot air to lift the chip off) and then tapping off of the logical voltage connections on the board (refer to the picture below)...
