ArduCAM Introduces A Third Party Raspberry Pi

Posted on by

There are hundreds of ARM-based Linux development boards out there, with new ones appearing every week. The bulk of these ARM boards are mostly unsupported, and in the worst case they don’t work at all. There’s a reason the Raspberry Pi is the best-selling tiny ARM computer, and it isn’t because it’s the fastest or most capable. The Raspberry Pi got to where it is today because of a huge amount of work from devs around the globe.

Try as they might, the newcomer fabricators of these other ARM boards can’t easily glom onto the popularity of the Pi. Doing …read more

Hackaday Prize: 20 Projects that Make Us All Citizen Scientists

Posted on by

We live in a time of unparalleled access to technology and this has the power to make life better for everyone. Today we are excited to announce twenty spectacular builds that use access to technology to move scientific exploration within the reach of all. These are the winners of the Citizen Scientist challenge of the 2016 Hackaday Prize. Themes tackled in this round include blood glucose monitoring, insole sensing for analyzing your footfalls, lab equipment like automated microscopy, sensors to measure the world around us, and more.

The winners for the Citizen Scientist portion of the Hackaday Prize are, in …read more

Hackaday Prize Entry: A Better Way Of Cheating

Posted on by

Believe it or not, some video games are still developed for the PC. With video games come cheat codes, and when they’re on the PC, that means using a keyboard. You can easily program any microcontroller to send a string of characters over a USB port with the touch of a button. Believe it or not, a lot of people haven’t put these two facts together. [danjovic] has, leading him to build a simple and cheap USB keystroke generator for quickly typing in cheat codes.

[danjovic] is basing his build around a Digispark, a cheap, USB-enabled ATtiny85 dev board. This, …read more

Hackaday Links: July 17, 2016

There’s going to be a new Nintendo console for Christmas! It’s the NES Classic Edition. It looks like a minified NES, with weird connectors that look like the connector for the Wii Nunchuck. There are no other details.

A site called “Motherboard” reports assembling a computer is too hard and a ‘nerve-wrecking [sic]’ process. Tip of the stovepipe to the Totalbiscuit.

When I was in elementary school, the playground had a twenty foot tall metal slide that faced South. During my time there, at least three of my classmates fell off it, and I distinctly remember the school nurse’s aid …read more

Case Modding The Old School Way

Posted on by

Since the release of the Raspberry Pi, the hallowed tradition of taking game consoles, ripping all the plastic off, and stuffing the components into nice, handheld form factors has fallen off the wayside. That doesn’t mean people have stopped doing it, as [Akira]’s masterful handiwork shows us.

This casemod began with a Nintendo GameCube ASCII keyboard controller, a slightly rare GameCube controller that features a full keyboard smack dab in the middle. While this keyboard controller was great for Phantasy Star Online and throwing at the TV after losing Smash, the uniqueness of this controller has outshadowed its usefulness. [Akira] …read more

Tearing Apart The Nintendo PlayStation

Posted on by

The mid 90s were a weird time for video game hardware. There were devices that could play videos from compact disks. Those never caught on. Virtual reality was the next big thing. That never caught on. The Sony PlayStation was originally an add-on for the Super Nintendo. That never caught on, but a few prototype units were produced. One of these prototype ‘Nintendo Playstations’ was shipped to a company that went into bankruptcy. Eventually, the assets of this company were put up for auction, and this unbelievably rare game console was bought by [Terry Diebold] for $75.

[Terry] allowed [Ben …read more

Hackaday Prize Entry: Linear Stepper Motors

Posted on by

Today, your average desktop 3D printer is a mess of belts, leadscrews, and pulleys. For his Hackaday Prize entry, [DeepSOIC] is eliminating them entirely. How’s he doing this? With a linear stepper motor.

Search Google for ‘linear stepper motor’ and you’ll find a bunch of NEMA-bodied motors with leadscrews down the middle. This is not a linear stepper motor. This is a stepper motor with a leadscrew down the middle. The motor [DeepSOIC] has in mind is more like a mashup of a rack gear and a maglev train. The ‘linear’ part of this motor is a track of magnets …read more

Retrotechtacular: The US Air Force Has The Biggest Fleet

Posted on by

When it comes to the superlatives of aviation, there are aircraft larger than the C-5 Galaxy. [Howard Hughes]’s Spruce Goose has the largest wingspan, and the Soviet and now Ukranian Antonov AN-225 Mriya has the largest cargo capacity. When it flies in the next year or so, Scaled Composites Stratolaunch – a twin-hulled beast of a plane designed to haul rockets up to 30,000 feet – will be the aircraft with the largest wingspan and the greatest cargo capacity.

These superlatives, while completely accurate, fail to realize these huge planes are one of a kind. There is no plan to …read more

Hackaday Prize Entry: A Simple CNC

Posted on by

3D printers are all the rage, but there’s still space for more traditional CNC machines. For their Hackaday Prize entry, [Andy], [Tim], and [Chris] are building the Sienci Mill – a simple desktop CNC mill that’s able to cut drill and carve everything from wood to circuit boards.

As far as desktop CNC machines go, it doesn’t get much more simple than this. They’re using steel plates for the rails, NEMA 17s for the motors, and a simple stepper motor driver Arduino shield for the controller. The more complex parts are 3D printed, and the BOM doesn’t add up to …read more

Hackaday Prize Entry: The World’s First Tampon Monitor

Posted on by

[Amanda], [Jacob], [Katherine], and [vyshaalij] had a class project for their ‘Critical Making’ class at UC Berkeley. The task was to design a ‘Neo-Wearable’ that would fulfill an unmet need. Realizing women make up about 50% of the population and experience monthly periods for about half of their lives, they decided to make what can only be described as a tampon monitor. It’s a small device that monitors the… uh… ‘fullness’ of a tampon. Yes, it’s wearable technology that is actually useful, and a great entry for the Hackaday Prize.

The my.Flow, as the team are calling it, uses mechanical …read more
