Collaborate Disseminate
Remember those actions movies like The Fast and the Furious where cars are constantly getting smashed by fast flying bullets? What would it have taken to protect the vehicles from AK-47s? In [PrepTech]’s three-part DIY composite vehicle armor tutorial, he shows how he was able to make his own bulletproof …read more

[Bitluni]’s motto seems to be, “When you’re busy, get busier.” At least that would explain adding even more work to his plate in the run-up to the Hanover Maker Faire and coming up with a ten-player game console from scratch.
As for this being extra work, recall that [bitluni] had …read more
Maybe you’ve heard of a TV show called The Simpsons. Steamed Hams make a one-gag appearance in an unforgettable luncheon where Principal Skinner poker-faces his way out of a disaster with Superintendent Chalmers. Meanwhile, over on imgur, [Agumander] has put a black and white screencap from Steamed Hams in …read more

“Never Twice the Same Color” may be an apt pejorative, but supporting analog color TV in the 1950s without abandoning a huge installed base of black-and-white receivers was not an option, and at the end of the day the National Television Standards Committee did an admirable job working within the …read more

Join us Wednesday at noon Pacific time for the ESP32 Video Tricks Hack Chat!
The projects that bitluni works on have made quite a few appearances on these pages over the last couple of years. Aside from what may or may not have been a street legal electric scooter, most …read more
Props for your little RC airplane or drone are effectively consumables. They’re made of plastic, they’re cheap, and you’re going to break a lot of them. When you start swinging something larger than 12 inches or so, things start getting expensive. If you’re building gigantic octocopters or big RC planes, those props start adding up. You might not think you can build your own gigantic carbon fiber propellers, but [Tech Ingredients] is here to prove you wrong with an incredible video demonstration of the construction of large propellers
The key ideas behind the build are laid out in a video …read more

We’ve seen FDM printers lay down layers by extruding plastic in a line. We’ve seen printers use sintering and lithography to melt or cure one layer at a time before more print medium moves into place for the next layer. What we’ve never seen before is a printer like this that builds parts from distinct layers of substrate.
At the International Manufacturing Technology Show last week I spoke with Eric Povitz of Impossible Objects. The company is using a “sheet lamination process” that first prints each layer on carbon fiber or fiberglass, then uses a hydraulic press and an oven …read more

Games like Pong are legendary, not only in the sense that they are classic hours fun but also that they have a great potential for makers in stretching their learning legs. In an attempt at recreating the original paddle games like Pong and Tennis etc, [Grant Searle] has gone into the depths of emulating the AY-2-8500 chip using an Arduino.
For the uninitiated, the AY-3-8500 chip was the original game silicon that powered Ball & Paddle that could be played on the domestic television. Running at 2 MHz, it presented a 500 ns pixel width and operated to a maximum …read more
Where would the world be today without Pong, perhaps a lot less fun? For people like [Linker3000] the game is an inspiration toward teaching the next generation of hackers to build and play their own version using Micro:bits as controllers!
Aiming for doing all manner of diligence, [Linker3000] says the code can simply be uploaded to an Arduino — foregoing throwing together a circuit of your own — if you want to jump right into things. For the workshop environment, this setup uses composite video outputs — but this shouldn’t be an issue as most TVs still retain these inputs. …read more
If you want a custom video game system, you could grab a used computer, throw an emulator on it, and build yourself a custom arcade cabinet. On the other hand, if you’d rather not deal with emulators, you can always use a console and modify it into your own tiny arcade cabinet using the original hardware. That’s what the latest project from [Element18592] does, using an Xbox 360 Slim and a small LCD screen to make a mini-arcade of sorts.
The build uses a 7″ TFT LCD and a Flexible Printed Circuit (FPC) extension board. The screen gets 12V power …read more
