In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Abstract: this paper proposed a cross-chain multi-dimensional reputation model based on block-chain to deal with the nodes’ risk assessment in block-chain. When the nodes joined the network, the block ...

There’s a well-known movie trope in which a hacker takes control of the traffic lights in a city, causing general mayhem or ...

The Dabao open-source hardware board features a Boachip-1x RISC-V MCU, whose RTL Verilog files are also open, and is IRIS inspectable.

The I2CKeyPad8x8 library implements the reading of a 8x8 keypad by means of a PCF8575. Smaller keypads, meaning less columns or rows (e.g. 5x4) can be read with it too. Sometimes you need to control ...

This repository contains code for an interview platform to conduct AI-led interviews in research studies as well as notebooks for the AI-assisted analysis of the resulting transcripts. Conducting and ...

If you spend a lot of time around Harley-Davidson bikes, you'll notice a peculiarity among these American motorcycles. Each model has a code consisting of letters and numbers. However, these codes are ...

Abstract: We establish an equivalence between two important random ensembles of linear codes: random linear codes (RLCs) and random Reed-Solomon (RS) codes. Specifically, we show that these models ...

Gaming PCs One Redditor has 3D-printed a big yellow air duct to attach to their GPU, and the results are middling: It 'does nothing but it looks cool' Gaming Keyboards As an ergonomic keyboard skeptic ...

Building a DIY Arduino game controller requires specific hardware components. The table below lists all the components required to build the Arduino Uno game controller project. These components are ...
