Although we’ve never had the privilege to drive one, [skaarj] tells us Dacia made some terrible cars. The Dacia 1310, a communist clone of the Renault 12, was cheap, had sixty-two horses under the hood, and was easy to maintain. The cabin, by all accounts, is a bit lacking, giving [skaarj] the opportunity to improve the instrument cluster and dash. He’s not throwing a stereo in and calling it a day – [skaarj] is upgrading his Dacia with retro-futuristic components including a vacuum tube amp, a CRT computer display, and an unspeakably small dumb terminal.
[skaarj]’s build began with a hit and run accident. With most of the body panels on the passenger side of the car removed, [Skaarj] ground some rust, rattle canned some rust proof paint, and bondoed the most offensive corrosion. Work then began on the upgraded dash, with a few choice components chosen including an old Soviet television, a hardware neural network to determine hardware faults, and a bizarre implementation of a CAN bus on a car without any of the requisite electronics.
This is one of those projects that can go on forever; there’s a lot you can do with the dashboard of a car if you’re not constrained by a suffocating desire to appear normal. In that respect, [skaarj] has this one locked up – he’s got a vacuum tube amplifier and enough CRTs in this car to add retro satellite navigation. It’s a great entry for The Hackaday Prize, as something cool is sure to come out of this project.
There’s an old saying that the only two things that are certain are death and taxes. However, unless you live in a nudist colony, there’s probably also laundry. [Darpan Bajaj] and some friends were at a hackathon and decided to put their washing machine on the Internet.
Most of us here at Hackaday — and many Hackaday readers, judging by the comments — are a little suspicious about how much we really need everything attached to the Internet. However, a washing machine is probably not a bad idea: you use it often, you need to know when it is done, and you probably don’t want to just sit and watch it spin. Besides, the intended installation is in a hostel where there are multiple machines and many potential users.

[James] works from home. His office is filled with objects that can be described with adjectives such as, “expensive,” and, “breakable.” His home, however, is filled with professional object-breakers known as children. To keep these two worlds from colliding, he installed a keypad lock on his office door. The potential side-effect of accidentally training his children to be master safe-crackers aside, the system seems to work so far.
However, being a hacker, the tedium of entering a passcode soon grew too heavy for him. Refusing to be a techno-peasant, he set out to improve his lock. The first step was to reverse engineer the device. The lock is divided into two halves, one has a keypad and handle, the other actually operates the lock mechanism. They are connected with a few wires. He hooked an oscilloscope to the most likely looking candidates, and looked at the data. It was puzzling at first, until he realized one was a wake-up signal, and the other was the data. He then hooked the wires up to a Bluetooth-enabled Arduino, and pressed buttons until he had all the serial commands the door lock used.
After that it was a software game. He wrote code for his phone and the Arduino to try out different techniques and work out bugs. Once he had that sorted, he polished the app and code until he reached his goal. All of the code is available on his GitHub.
Finally, through his own hands, he elevated himself from techno-peasant to wizard. He need but wave his pocket oracle over the magic box in front of his wizard’s lair, and he will be permitted entry. His wizardly trinkets secure from the resident orcs, until they too begin their study of magic.
We’ve seen a few remote controlled turret builds in the past, but this one from [Noel Geren] is pretty neat: it shoots water and uses Bluetooth Low Energy (BLE) for control. Check it out in action in the video below.
[Noel] used the guts of a Nerf Thunderstrike water gun for the firing mechanism, combined with a 3D-printed enclosure and a servo that rotates the turret top. The pump from the gun is connected to a simple relay that replaces the trigger. Both the relay and the servo are connected to an RFDuino with a servo shield, which is programmed to respond to simple commands to rotate and fire.
It’s a nice junk build, and [Noel] has released all of the files for download if you want to build your own. It would make a nice weekend build or a project to do with the kids.

This Saturday, April 23, we’re hosting a worldwide Hackaday meetup called World Create Day, and we want you to be a part of it. The 2016 Hackaday Prize is all about solving technology problems, and if you’re looking for an excuse to meet up with a few fellow tinkerers, this is it.
Right now, we have dozens of Hackaday meetup hosts planning their own get together. It’s six continents of awesome, and that’s only because winter is starting to set in on Antarctica. Today we’re taking a closer look at what’s lined up in North and South America. We have meetups from the shores of Venezuela to the birthplace of the worst president the United States has ever had. We have meetups in Baltimore and El Paso, and from Silicon Valley to New York City.
The goal for these meetups is to find fellow hackers and tinkerers, suss out a few ideas on what you’re working on, and start a project for The Hackaday Prize. We’re wrapping up the first stage of The Hackaday Prize, Design Your Concept this coming Monday, where all you need is an idea. Saturday’s World Create Day is the perfect time to brainstorm your tech solution with some friends and get it submitted ahead of the deadline. If you have an idea for the next great Internet of Things, an application for the RISC architecture that is gonna change everything, or just want to show off your flubber prototype, this is the event to go to.
This is the opportunity to find some like-minded hackers in your neck of the woods, and it’s not an event to miss. If you’re looking for a meetup in your area, check out the map here. If you’re interested in hosting one of these shindigs, fill out this form and we’ll set you up.
We’ll take a closer look at the meetups planned on other continents as the week progresses. If you’re still thinking of getting your own meetup on the map, now’s the time!
It’s amazing how quickly a technological pivot will erase the existence of what was previously a modern marvel. A great example of this is the live video projection technology known as the Eidophor. In the beginning there was film, and if you shined a light through it followed by a set of lenses you could project an image for all to enjoy. But what if you didn’t want to wait for film to be developed? What if you wanted to project live video, or real-time data for a room full of people who could not be served by even the biggest of the cathode-ray tubes of the time? This question led to the development of the Eidophor whose story has been all but lost.
Mike Harrison is trying to revive the details of this amazing engineering feat and presented his findings during his talk at the Hackaday | Belgrade conference. Mike is interested in technology that is “impractical, ridiculous, absurd, or stupidly expensive” and the Eidophor certainly ticks all of those boxes. Check it out below and join us after the break where we’ll touch on the myriad challenges of developing projection technology based on hot oil and high voltage.

Researchers in Japan have created a 3-micrometer display that looks like plastic wrap and can make any part of your skin into an electronic display. The idea isn’t new, but this display is far thinner and more durable than previous devices. It also lasts longer (several days) and has increased brightness.
The display uses polymer LEDs to form a seven-segment digit, so you aren’t going to stream Netflix to the back of your hand anytime soon. However, the team wants to build more advanced displays that could one day replace smartwatch or smartphone screens.
