Nostalgic Camera Is A Mashup Of Analog Video Gear

December 18, 2025 by 3 Comments

These days, you get a fantastic camera with the purchase of just about any modern smartphone. [Abe] missed some of the charm of earlier, lower-quality digital cameras, though, and wanted to recreate that experience. The way forward was obvious. He built a nostalgic digital video camera from scratch!

[Abe] figured he could build the entire project around analog gear, and then simply find a way to store the video digitally, thus creating the effect he was looking for. To that end, the build is based around a small analog video camera that’s intended for use with FPV drones. It runs on 5 to 20 volts and outputs a simple composite video signal. This makes it easy to display its output on a small LCD screen, originally intended to be used with an automotive reversing camera. These were both paired with a mini video recorder module from RunCam, which can capture composite video and store it on a microSD card in 640 x 480 resolution.

These parts were quickly lashed together, with the camera sending its output to the RunCam video recorder module, which then passed it on to the screen. Everything worked as expected, so [Abe] moved on to implementing an on-screen display using the MAX7456 chip, which is built specifically for this purpose. It overlays text on the video feed to the screen as commanded by an RP2040 microcontroller. Once that was all working, [Abe] just had to provide a battery power supply and wrap everything up in a nice retro-styled case. Then, at the last minute, the separate camera and recorder modules were replaced by a TurboWing module that combined both into one.

The result is a nifty-looking camera that produces grainy, slurry, old-school digital video. If you love 640 x 480 as a resolution, you’ll dig this. It’s got strong 90s camcorder vibes, and that’s a very good thing.

We love a good custom camera around these parts, especially those that offer deliciously high resolution. If you’re building your own, be sure to let us know. Video after the break.

A Ping Pong Ball LED Video Wall

May 17, 2019 by 6 Comments

Constrained builds are often the most fun. Throw an artificial limit into the mix, like time limiting your effort or restricting yourself to what’s on hand, and there’s no telling what will happen.

[bitluni] actually chose both of those constraints for this ping pong ball LED video display, and the results are pretty cool, even if the journey was a little rough. It seems like using sheet steel for the support of his 15 x 20 Neopixel display was a mistake, at least in hindsight. A CNC router would probably have made the job of drilling 300 holes quite a bit easier, but when all you have is a hand drill and a time limit, you soldier on. Six strings of Neopixels fill the holes, a largish power supply provides the 18 or so amps needed, and an Arduino knock-off controls the display. The ping pong ball diffusers are a nice touch, even if punching holes in them cost [bitluni] a soldering iron tip or two. The display is shown in action in the video below, mostly with scrolling text. If we may make a modest suggestion, a game of Pong on a ping pong ball display might be fun.

[bitluni] says that the display is on its way to Maker Faire Berlin this weekend, so stop by and say hi. Maybe he’ll have some of his other cool builds too, like his Sony Watchman Game Boy mashup, or the electric scooter of questionable legality.

Wiimote Finger Tracking Music Controller

The Evolution Control Committee has been doing live mashup performances for many years and recently upgraded their hardware. Inspired by [Johnny Lee]’s Wiimote whiteboard, they built a rear projection display they could use during performances. It displays a dense collection of samples in Ableton Live. On each of the performer’s hands is an IR LED mounted to a thimble. By touching the thumb to the forefinger, the LED turns on. Two Wiimotes watch for these IR flashes to trigger mouse clicks. [TradeMark G] found the Ableton display too complex to navigate quickly and accurately with a mouse; this new display make things much easier and enjoyable.

Hackaday Podcast Episode 350: Damnation For Spreadsheets, Praise For Haiku, And Admiration For The Hacks In Between

December 19, 2025 by 1 Comment

This week’s Hackaday Podcast sees Elliot Williams joined by Jenny List for an all-European take on the week, and have we got some hacks for you!

In the news this week is NASA’s Maven Mars Orbiter, which may sadly have been lost. A sad day for study of the red planet, but at the same time a chance to look back at what has been a long and successful mission.

In the hacks of the week, we have a lo-fi camera, a very refined Commodore 64 laptop, and a MIDI slapophone to entertain you, as well as taking a detailed look at neutrino detectors. Then CYMK printing with laser cut stencils draws our attention, as well as the arrival of stable GPIB support for Linux. Finally both staffers let loose; Elliot with an epic rant about spreadsheets, and Jenny enthusiastically describing the Haiku operating system.

Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

It’s dangerous to go alone. Here, take this MP3.

Back To The Future, 40 Years Old, Looks Like The Past

July 3, 2025 by 81 Comments

Great Scott! If my calculations are correct, when this baby hits 88 miles per hour, you’re gonna see some serious shit. — Doc Brown

On this day, forty years ago, July 3rd, 1985 the movie Back to the Future was released. While not as fundamental as Hackers or realistic as Sneakers, this movie worked its way into our pantheon. We thought it would be appropriate to commemorate this element of hacker culture on this day, its forty year anniversary.

If you just never got around to watching it, or if it has been a few decades since you did, then you might not recall that the movie is set in two periods. It opens in 1985 and then goes back to 1955. Most of the movie is set in 1955 with Marty trying to get back to 1985 — “back to the future”. The movie celebrates the advanced technology and fashions of 1985 and is all about how silly the technology and fashions of 1955 are as compared with the advancements of 1985. But now it’s the far future, the year 2025, and we thought we might take a look at some of the technology that was enchanting in 1985 but that turned out to be obsolete in “the future”, forty years on.

A terminal window with a search for "Guineau Pig Olympics" is inset on a photo of an ortholinear keyboard attached by a yellow USB cable to a 70s aluminum and plastic Super 8 film editor/viewer. The device has a large screen on the right hand side, a silver grate on the left, and a tray at the bottom for slotting in film.

Super 8 Film Editor Reborn As A YouTube Terminal

October 30, 2022 by 14 Comments

We love hacks that give new life to old gadgets, and [edwardianpug]’s YouTube Terminal certainly fits the bill by putting new hardware inside a Super 8 film editor.

[edwardianpug] could have relegated this classy-looking piece of A/V history to a shelf for display, but instead she decided to refresh its components so it could display any YouTube video instead of just one strip of film at a time. The Boost-Box keeps the retrofuturistic theme going by using the terminal to search for and play videos via Ytfzf.

The original screen has been replaced by an 800×600 LCD, and the yellow USB cord gives a nice splash of color to connect the ortholinear keyboard to the device. Lest you think that this “ruined” a working piece of retro-tech, [edwardianpug] says that 20 minutes would get this device back to watching old movies.

Are you looking for more modern and retro mashups? Check out these Dice Towers Built In Beautiful Retro Cases, a Vacuum Tube and Microcontroller Ham Transmitter, or this Cyberdeck in a Retro Speaker.

Food Irradiation Detector Doesn’t Use Banana For Scale

June 28, 2022 by 66 Comments

How do the potatoes in that sack keep from sprouting on their long trip from the field to the produce section? Why don’t the apples spoil? To an extent, the answer lies in varying amounts of irradiation. Though it sounds awful, irradiation reduces microbial contamination, which improves shelf life. Most people can choose to take it or leave it, but in some countries, they aren’t overly concerned about the irradiation dosages found in, say, animal feed. So where does that leave non-vegetarians?

If that line of thinking makes you want to Hulk out, you’re not alone. [kutluhan_aktar] decided to build an IoT food irradiation detector in an effort to help small businesses make educated choices about the feed they give to their animals. The device predicts irradiation dosage level using a combination of the food’s weight, color, and emitted ionizing radiation after being exposed to sunlight for an appreciable amount of time. Using this information, [kutluhan_aktar] trained a neural network running on a Beetle ESP32-C3 to detect the dosage and display relevant info on a transparent OLED screen. Primarily, the device predicts whether the dosage falls into the Regulated, Unsafe, or just plain Hazardous category.

[kutluhan_aktar] lets this baby loose on some uncooked pasta in the short demo video after the break. The macaroni is spread across a load cell to detect the weight, while [kutluhan_aktar] uses a handheld sensor to determine the color.

This isn’t the first time we’ve seen AI on the Hackaday menu. Remember when we tried those AI-created recipes?
