DMX Animatronic Robot

“This project describes the development of a fully functional animatronic prototype. It is implemented from scratch and it aims to be a guide for the development of future more complex animatronic robots. The system is based on an Arduino microcontroller …

Dual Trace Oscilloscope

“When I build my previous mini oscilloscope I wanted to see how well I could make my smallest ARM microcontroller a STM32F030 (F030) perform, and it did a nice job. In one of the comments it was suggested that a …

Engineers design a device that operates like a brain synapse

“Ion-based technology may enable energy-efficient simulations of the brain’s learning process, for neural network AI systems. Teams around the world are building ever more sophisticated artificial intelligence systems of a type called neural networks, designed in some ways to …

ESP-01 CONTROL RGB LED CUBE 4x4x4

“ESP-01 ESP8266 can be used as a stand-alone device to control a RGB led cube 4x4x4. Today, I’d like to share how ESP-01 ESP8266 can be used as a stand-alone device to control a RGB led cube …

Excitons form superfluid in certain 2D combos

“Mixing and matching computational models of 2D materials led scientists at Rice University to the realization that excitons — quasiparticles that exist when electrons and holes briefly bind — can be manipulated in new and useful ways. The researchers identified a small …

Face-Masks Disinfection Device — needlab

“UV-C / heat, Arduino-controlled, face-mask disinfecting device for Coronavirus (SARS-CoV-2). #COVID19DetectProtect FFP1 and FFP2 masks are indispensable protective elements during epidemics. They are intended for single-use, but during a crisis the re-usage is inevitable and disinfection mechanisms are required …

HDSP clock with SCD5583 display

“Here is another interesting “intelligent” LED matrix display, whose name actually makes some sense (unlike HDSP-2354, among many others): SCD5583A. I reckon it means: “Serial Character Display with 5x5x8 dot matrix”. 3 is the code for green (0 for …

Head Phone Amp With Custom PCB

“I’ve been building (and trying to perfect) the headphone amp for some time now. Some of you would have seen my previous ‘ible builds. For those that haven’t I have linked these below. On my older builds I …

Hello MicroBlaze on Arty-A7

“See how to bring up Xilinx’s soft-processor implementation, the MicroBlaze, on the Arty-A7 board. The Arty A7 board is a development board for Xilinx’s Artix-7 FPGA chip. It comes in two sizes in terms of the amount of …

Homemade Arduino TV-B-Gone

“When I was younger I had this really cool gadget called a TV b gone Pro and it’s basically a universal remote. You can use it to turn on or off any TV in the world and it was …
