Automation for the NES
Old hardware might not be anywhere close to as powerful as modern technology, but it does have a few perks. Aesthetics can of course drive the popularity of things like …read more Continue reading Automation for the NES

[Ken Shirriff] Takes a Bite of the Apple-I
The Apple-I was a far cry from Apple’s later products. A $666 single-board computer, the product had some unique design features including using a shift register for video memory to …read more Continue reading [Ken Shirriff] Takes a Bite of the Apple-I
Spectrum Display Uses Tiny CPU and Many LEDs
You would think the hard part about creating a spectrum analyzer using a pint-sized ATTiny85 would be the software. But for [tuenhidiy], we suspect the hard part was fabricating an …read more Continue reading Spectrum Display Uses Tiny CPU and Many LEDs
Apollo Shift Register is Discrete
We’re unabashed fans of [Ken Shirriff] here at Hackaday, and his latest post about an Apollo-era transistorized shift register doesn’t disappoint. Of course, nowadays a 16-bit shift register is nothing …read more Continue reading Apollo Shift Register is Discrete
Decoding the PS/2 Keyboard Protocol Using Good Old Fashioned Hardware
1987 was a glorious year. It brought us the PS/2 keyboard standard that’s still present on many a motherboard back panel to this day. (It also marked the North America/Europe release of The Legend of Zelda but that’s another article.) …read more

Discrete-Logic UART Keeps 8-Bit TTL Computer Connected
Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in terms of performance. And yet they still forge ahead with their breadboards full of chips and tangles of wire. …read more

Matrix of Resistors Forms the Hot Hands Behind This Thermochromic Analog Clock
If you’re going to ditch work, you might as well go big. A 1,024-pixel thermochromic analog clock is probably on the high side of what most people would try, but apparently [Daniel Valuch] really didn’t want to go to work that day.
The idea here is simple: heat up a …read more

A VFD Wall Thermometer
Want to build something using VFD tubes, but don’t need yet another clock project? In that case, this wall mounted temperature and humidity display created by [commanderkull] might be exactly what you’re looking for. With six IV-11 tubes, this display is a practical way to add some of that gorgeous …read more
Programmable Wrist Synth Pushes The Envelope
Synths are a ton of fun no matter how good or bad they sound. Really, there are no bad-sounding ones, it’s just that some are more annoying to listen than others to if you’re not the one making the beep boops. [Clem] had built a tiny LDR-based synth into a …read more

Chaining Together A 16×2 Bubble LED Display
We’ve recently noticed an uptick of interest in so-called “bubble displays”: vintage alphanumeric LEDs which are probably best remembered as being used in watches and calculators before the LCD took over. Today they’re available as surplus or even salvage for literally pennies, but unfortunately they only provide four or five …read more
