The Voltage Divider The AtTiny167 didn't have enough pins for two controllers so, for each port, I made a voltage divider out of three resistors which allows two digital inputs to be read by one analogue GPIO pin. You can see the circuit working...
New year, new hacks I've decided to finally have a go at the bulky thermometer with nixie displays that's been languishing in my cupboard. I bought it at the same surplus shop where my #Restoring a Beckman neon display clock came from. The box is quite...
I have found the SmartResponse-XE an interesting "Arduino-compatible" device. With BASIC installed and the added "Q" token (alias for PRINT) to allow realtime evaluation of simple math. However, the math functions of "+", "-", "/", "*" all...
Yes, there's an undeniably vast amount of famous pop and rock songs out there using a chord progression built around the Tonic (I), Dominant (V), Submediant (vi) and Subdominant (IV). You won't even need the submediant to cover all of blues, country...
The project has been designed to 'leave nobody behind' who does not have access to a 3D Printer, and as such, all the game components can be printed on thin paper and thin card if you have it. It is meant to be a provocation about what is possible if...
This project has several components, each of which might potentially be its own project:1) The modded monocular head-mounted display/goggles2) The haptic glove interface3) The dehumidification mechanism for the goggles4) The software stack for implicit...
To provide process optimization of metal fabricating self-replicating rapid prototyper (RepRap) 3-D printers requires a low-cost sensor and data logger system to measure current (I) and voltage (V) of the gas metal arc welders (GMAW). This paper builds...

Couldn't take a picture with my phone. The screen showed white block where the text should be. Their scroller example from https://hackaday.io/project/161859-2018-hackaday-superconference-badge/log/154558-basic-program-examples looks like:...
Time for technical details:1) Board recognition.We have used the camera (in android phone with IP Webcam app) to grab the photo of board and send it to the host computer. Next, the image is cropped translated to board square - then it is divided into...
current follower count,current account name and ID,three preceding follower counts. First of all, to manage to glean information from Twitter by avoiding any authentification process pertaining to the Twitter API, I chose to use a content delivery network...
At that moment in time, the "Hobby" computer was cut of the edge technology:- compatible with both of the major Z80 operating systems of the time: CP/M and ZX Spectrum- single (256 x 192) and double (512 x 192) screen resolution- hardware switchable...
This simple example can be extended in several ways and used in more complex gesture recognition cases, such as map navigation and routes creation, TV interface control when playing games or switching channels, control of children's toys by hand movements,...
Video showing the bat sonar in actionThis video shows the sensor in action. The left graph shows the identified targets. The size of the circles indicates the strength, and the location on the graph is their measured location. The graph...
The project's drive is to empower people by allowing them to have access to energy through a community driven project and a low-cost design.To this aim, this project's will explore the potential of building a low-cost alternator out of industrial plastic....
