I ended up using the key combination for On and Mode (it seemed appropriate) to change the mode, which basically is between TI-83 keyboard mode for the TI-83 emulator and Regular mode which allows through various submodes access to just about all of...
When I set about this project the first thing I wanted to work out was what LED I was going to use, as this would drive the requirements of everything else in the project, driver, lens, heatsinking, etc. Due to personal preference I decided that I wanted...
Z-Uno was designed to allow people to make their own IoT devices for their Smart Homes. Many times we were asked "Is there a pressure/radiation/water level/.../whate ever sensor in Z-Wave?" and we found that it would be cool if people can make their...
With the compass functionality tested on a breadboard, the next step is to transfer it to a universal prototyping board, adding a status display and IO expansion ports to drive a LED ring that simulates the horizon. For the board, I am going to use the...
July was a tough month, and August is no different. Due to some components arriving late, I've only been able to start my work on the Hackaday.io project with considerable delay. So I had to catch up with everything and squeeze the entire development...
I have continued debugging the hardware mock-up. The fundamental target was to program a simple RPN calculator UI with 6 operations plus a number of scientific functions. The integration with BASIC will come later, after all the hardware components are...
The idea was quite simple. Buy a linear actuator from OpenBuilds with a stepper motor, attach a camera on top of it, two tripods below, assemble a control box with some Arduino-compatible, WiFi-enabled board and write an Android application that would...
What if I told you it was possible to SAFELY use ANY SmartPhone as a robot brain? On any smartphone with a browser, load a freely hosted github.com webpage with Javascript that blinks areas on the screen to send motor commands to an e.g. Arduino....
The story so far... Update: Row scanning working.Known/working: Building and loading via JTAG new firmware into the main FPGA. This firmware is starting from scratch, we don't understand much yet about the default Barco firmware, although we've dumped...
Project Overview Video for Hackaday Prize 2023: The End Result The Plan In principle it is simple: by connecting different combinations of binary value resistors in parallel, and assuming a constant input voltage, we can consume any arbitrary amount...
In this project, we will build a 2.4GHz Wlan scanner using the nRF24L01 radio board. In this project, the output delivers all the interference and information in the scanned area in the form of ASCII codes. In the project of making this scanner,...
Table of Contents 1. Hardware2. The serial console 1 Hardware The Netgear ReadyNAS 3138 is a 1U rack-mounted NAS server with 4 3.5'' SATA drive slots. I have recently purchased such a device in order to use it as a small home fileserver and decided to...
Dyson V6 Setup and Running System Dyson handheld vacuum cleaners utilize high RPM brushless DC motors. Specifications indicate that some models can reach as high as 125000 RPM. I’ve disassembled DC56(V2), V6, and V10 models. Each has a brushless single-phase...
I'm going to use the details section to contain the code usedThere are three main modules, and these are all placed in the standard user directory that the ESP 8266 SDK uses for building code.tm1638.h#include "c_types.h" #include "user_interface.h" #include...
