Chess Set From Car Partsmainlewinday

Mon, 29 May 2017 08:00:07 +0000

Chess has been around for an awfully long time, automobiles less so. However, there’s no reason the two can’t be combined, like in this chess set fashioned from automotive components.

The project was made as a gift, and is the sort of thing that’s quite accessible for an interested maker to attempt at home. Parts used to build the set include valves, valve springs, spark plugs, castellated nuts and pipe fittings. As the parts don’t actually need to be in good working condition, a haul like this could likely easily be had for less than $50 from the local pull-it-yourself …read more

Sega’s Game Gear Gets a Video Outputbuild_finishbigadamfabio

Mon, 29 May 2017 05:00:09 +0000

[EvilTim] dug deep into a classic system to finally give the Game Gear a proper video output.  The Game Gear was Sega’s answer to Nintendo’s Gameboy. Rushed to market, the Game Gear reused much of the hardware from the very popular Master System Console. The hardware wasn’t quite identical though – especially the cartridge slot. You couldn’t play Game Gear games on a Master System, and the game gear lacked an AV output, which meant gamers were stuck playing on a small fluorescent backlit LCD screen.

[EvilTim] wanted to play some of those retro titles on a regular TV using …read more

A Tube AM Transmitter In A Soup Cansoup-can-radio-featuredjennylist

Mon, 29 May 2017 02:00:58 +0000

A standard early electronics project or kit has for many years been the construction of a small broadcast transmitter with enough power to reach the immediate area, but no further. These days that will almost certainly mean an FM broadcast band transmitter, but in earlier decades it might also have been for the AM broadcast band instead.

The construction of a small AM transmitter presents some interesting problems for an electronic designer. It is extremely easy to make an AM transmitter with a single transistor or tube, but it is rather more difficult to make a good one. The modulation …read more

Boeing and DARPA are building a spaceplane. Right now it’s only a press release and a few concept images, but it looks like this is an air-launched system kind of like a Tristar/Pegasus, only much higher and completely unmanned. It’s a ton and a half to low earth orbit, with a goal of 10 flights in 10 days.

Up in Albany? There’s a new hacker con happening in a few weeks. Anycon is a hacking, infosec, and cyber security conference happening June 16 & 17th in Albany, NY. The organizers of this con ([Chris], and his company Leet Cybersecurity) are …read more

Hackaday Prize Entry: ESP32 Monster and Getting Started Quickly2025021493469095703_featuredhexagon5un

Sun, 28 May 2017 20:00:48 +0000

Prolific hacker [kodera2t] is working on his own “ESP32 monster board” dev board for the still-newish ESP32 WiFi module. His board has everything: Ethernet, OLED, LiPo, and even CAN-bus. But all that peripheral connectivity is worth nothing if you can’t program the microcontroller to use it.

The Arduino environment for the ESP32 is coming along quite nicely, but it’s not yet fully featured enough to run all of [kodera2t]’s hardware. To take advantage of all that, he needs to use Espressif’s SDK — called the “IoT Development Framework” or IDF for short. In his latest project log, [kodera2t] goes through …read more

IMSAI 8080 Resurrection8080wd5gnr1

Sun, 28 May 2017 17:01:52 +0000

When MITS introduced the Altair 8800–about 43 years ago–it spawned the first personal computer clone: the IMSAI 8080. The clone had several improvements and MITS had difficulty filling orders for real Altairs, so they sold pretty well. [IMSAI Guy] has one of these vintage computers that has been in storage for over 30 years. He’s restoring the thing and there are 26 (and counting) videos of his progress. You can see the second video below, but be sure to check out the others, too.

The IMSAI is famous for being in the movie Wargames. We miss computers with switches and …read more

A Flying, Fetching, Helping-Hand OmnicopterOmnicopter catching a ballstevendufOmnicopter propeller orientations

Sun, 28 May 2017 14:00:39 +0000

Wouldn’t it be nice if you had a flying machine that could maneuver in any direction while rotating around any axis while maintaining both thrust and torque? Attach a robot arm and the machine could position itself anywhere and move objects around as needed. [Dario Brescianini] and [Raffaello D’Andrea] of the Institute for Dynamic Systems and Control at ETH Zurich, have come up with their Omnicopter that does just that using eight rotors in configurations that give it six degrees of freedom. Oh, and it plays fetch, as shown in the first video below.

Each propeller is reversible to provide …read more
