Enforce Speed Limits with a Rusty Bike

They say you can’t manage what you can’t measure, and that certainly held true in the case of this bicycle that was used to measure the speed of cars in one Belgian neighborhood. If we understand the translation from Dutch correctly, the police were not enforcing the speed limit despite …read more

Stylish Alarm Clock Rocks a VFD

There are a great many display technologies available if you wish to make a digital clock. Many hackers seem to have a penchant for the glowier fare from the Eastern side of the Berlin Wall. [ChristineNZ] is one such hacker, and managed to secure some proper Soviet kit for an …read more

Hackaday Links: June 9, 2019

The Chicago Pile led to the Manhattan Project, which led to the atomic bomb. In Germany, there were similar efforts with less success, and now we have physical evidence from the first attempted nuclear reactor in Germany. In Physics Today, there’s a lovely historical retrospective of one of the …read more

Dead Bug Arduino Is Lively And Shield-Compatible

Microcontroller demo boards such as the Arduino UNO are ubiquitous on Hackaday as the brains of many a project which inevitably does something impressive or unusual. Sometime someone builds a particularly tiny demo board, or an impressively large one. In the case of the board featured here, the Arduino is …read more

Drag And Drop Files On Select Arduino Boards

Historically, getting files on to a microcontroller device was a fraught process. You might have found yourself placing image data manually into arrays in code, or perhaps repeatedly swapping SD cards in and out. For select Arduino boards, that’s no longer a problem – thanks to the new TinyUSB library …read more

Creating A Sonic Landscape With Glitching CD Player

CDs were a great advancement in audio quality when they were first put on the market. There’s no vinyl-style degradation of the medium if it’s played over and over, and there’s no risk of turning them into a giant pile of ribbon while rewinding like a cassette tape. The one …read more

Stator Library Makes Your Arduino Code Easier To Read

The readability of your code can make the difference between your project being a joy to work on, or an absolute headache. This goes double when collaborating with others. Having easily parsed code reduces your cognitive load and makes solving problems easier. To try and help with this, [PTS93] developed …read more

Arduino Leonardo Gets A Lockable Bootloader

Security is something that’s far too often overlooked in embedded devices. One of the main risks is that if the device doesn’t verify the authenticity of incoming firmware updates. [Walter Schreppers] was working on a USB password storage device, so security was paramount. Thus, it was necessary to develop a …read more

Insert Coin (Cell) To Play LedCade

In this era of 4K UHD game console graphics and controllers packed full of buttons, triggers, and joysticks, it’s good to occasionally take a step back from the leading edge. Take a breath and remind ourselves that we don’t always need all those pixels and buttons to have some fun. …read more

Play Tetris on a Transistor Tester, Because Why Not?

[Robson] had been using the same multimeter since he was 15. It wasn’t a typical multimeter, either. He had programmed it to also play the Google Chrome jumping dinosaur game, and also used it as a badge at various conferences. But with all that abuse, the ribbon cable broke and …read more
