By now, [CuriousMarc] and his team of volunteers are well versed in 1960s hardware restoration. So when a vintage IBM I/O Tester came into their possession, a full machine makeover was all but inevitable. The I/O Tester dates from around 1965, which roughly coincides with the introduction of IBM’s lauded System/360 computer mainframe. In addition to […]

Merry belayed Christmas and a happy new year everyone. I know, I am running a tiny bit late. My original plan was to release the tinyOSD and tinyFINITY sources ready for Christmas but then the usual things got into the way and I had to postpone this post. But here it is: I am releasing

Dear Adafruit, Sparkfun, Radioshack, and hobbyist companies of the like, I’m a high-schooler with zero dollars in the bank. I can’t really afford to buy a $60 Arduino from RS when I could buy it for $15 on ebay, from Shenzhen or Hong Kong. I understand that I am hurting your business by not buying

Branding can be done on wood with just about any old bit of hot metal, but if you want to do it well, properly-crafted tooling will go a long way. [Wesley Treat] has built just that with this modular branding iron design. The branding tooling itself is machined out of brass on an X-Carve CNC router,

When engineers consider offline switchers for systems ranging from telecom and datacom equipment to PCs and industrial supplies, they mainly think of bulky AC/DC front-end solutions in a variety of forms such as bricks, modules, and open-frame. However, there are many applications where offline switchers powered by AC mains are needed in small packages or

I’ve not used an FM radio for years, but if you’d like to teach younger generations about older technology and show them how to solder components there’s an RDA5807 based kit that would allow you to build DIY FM Radio operating in the 87 MHz to 108 MHz range. The JC-300 kit comes with a

Tesla is well known for making cars that can accelerate quickly, but there’s always room for improvement. [Warped Perception] decided that his Tesla Model S P85D needed that little bit of extra oomph (despite the 0-60 MPH or 0-97 km/h time of 3.1 seconds), so he did what any sensible person would: add three jet turbines

ABOUT THIS PROJECT I made a dice throwing prototype: if you press the button, a random number between 1 and 6 is generated and the corresponding number of LEDs are lit up. This was a holiday project with my kids 🙂 Dice throwing prototype using Arduino UNO, a button switch and 6 LEDs. Full tutorial
