David Williams Is “FPGA-Curious”

If you hadn’t noticed, we had a bit of an FPGA theme running at this year’s Superconference. Why? Because the open-source FPGA toolchain is ripening, and because many of the problems that hackers (and academics) are tackling these days have become complex enough to warrant using them. A case in …read more

Creating Easy Glass Circuit Boards At Home

This tip for creating glass substrate circuit boards at home might hew a bit closer to arts and crafts than the traditional Hackaday post, but the final results of the method demonstrated by [Heliox] in her recent video are simply too gorgeous to ignore. The video is in French, but …read more

A Mobile Terminal For The End Of The World

If civilization goes sideways and you need to survive, what are the bare essentials that should go in your bunker? Food and fresh water, sure. Maybe something to barter with in case things go full on The Postman. That’s all sensible enough, but how’s that stuff going to help …read more

Building A 6.5 Digit Voltmeter From Scratch

After initially working to create a modernized replica of a Czechoslovakian 4-digit Metra M1T242 voltmeter, [Jaromir Sukuba] figured that while he was at it, he might as well create a voltmeter that would be slightly more capable. This led to the design and construction of a brand-new, 6.5 digit voltmeter …read more

Tiny Cube Hosts a Hearty Tube

Tiny PCBAs and glowy VFD tubes are like catnip to a Hackaday writer, so when we saw [hamster]’s TubeCube tube segment driver we had to dig in to learn more. We won’t bury the lede here; let’s enjoy a video of glowing tubes before we go further:

The TubeCube is …read more

DIY Video Microscopy

Owning a Microscope is great fun as a hobby in general, but for hackers, it is a particularly useful instrument for assembly and inspection, now that we are building hardware with “grain of sand” sized components in our basements and garages. [voidnill] was given an Eduval 4 microscope by a …read more

Not All 7-Segment Displays Are Electronic

There are a variety of means by which numbers can be displayed from an electronic circuit, and probably the most ubiquitous remains the seven-segment display. Take seven LEDs, lamps, LCDs, VFD segments or mechanical flip-dot style units in the familiar rectangular figure eight, and your microcontroller or similar can display …read more
