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...
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,...
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...

Links to project details (GIT, Wiki, Docs) are on the left. The laziest intro to this project is the 2-minuite video created for THP Quarterfinals (i.e. the first video I made):Or even better, see my full 5-min final video (there is also the semifinal...

The main controller board is an off-the-shelf Parallax Quickstart board. I designed and built a custom shield that provided a power supply for the project and driver outputs (TC4427) for the LED strings. Though we didn't use it, the board also holds...
Typically, a user should create a pointer to a cfg_struct, initialize it with cfg_init(), and then perform actions on that object (lookup, add, delete) by passing the pointer to the functions here. At end of use, call cfg_free to clean up the object....
In the original configuration, the airswimmer is propelled by the tail fin, which can be flapped left-to-right using the remote. The whole fish can also be tilted up or down by moving the gondola, which holds the battery and receiver, forward and back...
Using an old Fairplay Scoreboard LED matrix to display scrolling messages (one of which was also for the kiddos birthday, scrolling "HAPPY BIRTHDAY")A PIC 16F870 was used for the controller. The factory controller was ditched as I was unsure how...
