Tim (cpldcpu) writes: Like many others, I was quite amazed to learn about a microcontroller sold for only 0.03 USD via the EEVblog last year. How was this possible? Many assumed this was a fire sale of an old product. Digging a bit further, it became apparent that there is an entire market segment of […]
Up-to-date documentation makes a project easy to learn about, but its a really boring job that takes a lot of time. Even great documentation eventually has outdated examples and screenshots that don’t quite match the latest version. BusPirate.com has a hacked together toolchain to keep the documentation fresh. It’s a three part process: Test scripts […]
Limpkin writes: I usually never use libraries… but made an exception for these quick projects ! I’m pretty sure that most people reading this very article know about the (very) cheap ESP8266 Wifi module. A bit more than a year ago, I actually made a small development board for it, which was recently used in […]
The factory of the world – Hackaday documentary on the Shenzhen Ecosystem When it comes to manufacturing, no place in the world has the same kind of allure as the Pearl River Delta region of China. Within just an hour-long train ride, two vastly different cultures co-exist, each with its unique appeal that keeps attracting […]
follower from rancidpacon writes, I recently wrote a 15-page getting started guide for the $5 ESP8266 WiFi modules for Kiwicon 8, a local New Zealand hacker con. It’s available as both HTML and a PDF. It provides details on: how to make the hardware connections using an FTDI Board or Arduino (with suitable disclaimer); how […]
If you’re into learning programming languages, you may what to check out a new programming language known as D. What is D?

Ivan writes to inform us of his new site, www.info-transistor.info. “It allows you to find the technical specs of transistors (bjt, mosfet and igbt) and even put this information here in the forum with the BBCODE export option!” Via the contact form.
Alan C. Assis writes with a new way to share and visualize KiCad components. It is not easy to find KiCad components. Normally people search at www.kicadlib.org or just “Google” for the component part-number + KiCad, but neither approach normally will return good results. At end of day he/she decides to “home-brew” their components. But […]
Makers in the open source hardware community are usually more preoccupied with tech details, with licensing considerations being an afterthought. This can lead to unintended consequences resulting from releasing a design under what proves to be either too permissive or restrictive. Simone Cicero tries to clear up confusion over characteristics and implications of the various […]
The new MSP430 selection guide is available from download from TI. This 25 page PDF provides an overview of the MCU line, dev boards and supporting peripherals.
It’s unfortunate that we have to consider these matters, but with governments worldwide obsessed with violating the privacy of ordinary citizens we found a well documented post which puts some flesh on what some naively view as skeletal paranoia. In this comprehensive article Violet Blue of ZDNet outlines the tools and techniques government agents worldwide […]
Gordon Williams has developed cheat sheets for ARM dev boards. He writes, “I got pretty frustrated working with ARM development boards – every time I’d choose a pin for some function I’d find out that it was used for some peripheral on the board – so it either wouldn’t work or it would break something […]

Why you should document your Open Source Hardware project: This specific moment, that moment when you start working on the refinements of a product to create the second version, could be a great moment to document your invention. In fact, when you start again the production process, you already know how to do things, and […]
In this newly declassified document entitled “Untangling the Web: a guide to internet research”, the NSA drops the docs on the governemnt’s view of internet research resources.
