Useless machines are generally built as a fun pastime, as they do nothing of value by their very definition. The most popular type generally involves a self-cancelling switch. However, there’s plenty of other useless machines to build, and we think [Jeffery’s] build is particularly creative. The build consists of an XY gantry that moves a standard […]

Back in 2007, Technologic Systems announced the TS-7800, a single-board computer (SBC) that was able to boot Linux 2.6 in under two seconds. At its core, The TS-7800 is equipped with a Marvel 500MHz ARM9 CPU and includes a user-programmable on-board FPGA (Field-Programmable Gate Array) with 12,000 LUTs (look-up tables). The TS-7800 was a powerful board at

This article describes the ESP-01, fitted with LUA firmware that is able to converse with a serial terminal in a high level language, store programs and data, turn things on and off in a package that costs almost nothing. The possibilities for ridiculously cheap remote temperature sensors and more are finally here. The software is
Probably the Cheapest WIFI Computer in the World (ESP8266+LUA) Continue Reading
Dualbooting your computer can be a chore, the more switching between OSes you have to do – which is why virtualization or having separate computers are the go-to for many. Failing that, we have no choice but to smooth over our dualbooting experience with various workarounds and helpers. [William Somsky] shares one such helper tool with us

How to build your own VGA-adapter My lifetime project: building an 8-bit computer using Z80 CPU. This week I had a bad flu and could not do anything useful so I decided to dig up my old plans for this project. I first re-designed many things, like power, CPU-board, IO-board and so on (my old

What it is: An Arduino-based light-sensitive switch for turning on a desktop computer. Why its cool: Use a Sonic Screwdriver to turn on your computer! Story: This project started, as I’m sure a lot of them do, as a result of boredom and the thought “Wouldn’t it be cool if…”. I am a fan of
Sonic Switch: Use a Sonic Screwdriver to turn on your computer! Continue Reading
Open source community BeagleBoard.org has announced their BeagleBone AI SBC which features a dual Cortex-A15 TI AM5729 SoC that enables AI support via dual C66x DSPs and 4x EVE cores. The SBC comes with 1GB RAM, 16GB eMMC, WiFi, and GbE. The SoC includes four powerhouse embedded-vision-engine (EVE) cores with AI capabilities. BeagleBoard.org’s limited product page says the SoC can run AI code

If you haven’t seen [Ken Shirriff]’s teardowns and reverse engineering expeditions, then you’re in for a treat. His explanation and demonstration of the Apollo digital ranging system is a fascinating read, even if vintage computing and engineering aren’t part of your normal fare. The average Hackaday reader should be familiar with the concept of determining the distance

Acrosser Technology has recently released a brand new entry-level 3.5” single board computer (SBC). This new AMB-BT19S1 single board computer is powered by an Intel Bay Trail SoC. It features 8GB RAM, dual display support, plus SATA, mSATA, mini-PCIe, serial, USB 3.0, and GbE ports. As the SBC market has already seen newer Atom processor families such as Cherry Trail, Braswell,
ACROSSER’S ENTRY-LEVEL AMB-BT19S1 SBC HAS INTEL BAY TRAIL SOC Continue Reading
Simple Output with LEDs Arduino Digital Output Project introduces users to the Arduino software environment and basic digital circuit construction. By running example programs, users gain foundational knowledge of Arduino’s capabilities. They then apply this knowledge to build and control a simple LED circuit. This hands-on experience bridges software and hardware, teaching core concepts of
