A Masterpiece Of 3D Printed Case Modding. With An Ouya.

Ouya

We’ve seen a few of [Downing]‘s portabalized console builds before, but this one is his first build in over two years. That’s a lot of time, and since then he’s picked up a lot of great fabrication techniques, making this one of the best looking portables we’ve ever seen. It’s a repackaging of an Ouya, but we won’t hold that against him, it’s still an amazing piece of work.

In the build log, [Downing] started off this build by using a 3D printed enclosure, carefully milled, filled, and painted to become one of the best one-off console repackagings we’ve ever seen. The speaker and button cutouts were milled out, and an amazing backlit Ouya logo completes the front.

Stuffing the Ouya controller inside a case with a screen, battery, and the console itself presented a challenge: there is no wired Ouya controller. Everything is over Bluetooth. Luckily, the Bluetooth module inside each controller can be desoldered, and slapped on a small breakout board that’s stuffed in the case.

It’s a great build, and in [Downing]‘s defense, the Ouya is kinda a cool idea. An idea much better suited to a handheld device, anyway. Videos below.

Replicator 1 Receives a PID Controlled Heated Chamber

Replicator 1 PID Heated Enclosure

Improving 3D print quality is a bit of a black magic — there are tons of little tweaks you can do to your printer to help it, but in the end you’re just going to have to try everything. Adding a heated build enclosure however is one of those things almost guaranteed to improve the print quality of ABS parts!

And for good reason too — heated build enclosures are one of the outstanding “patented 3D printing technologies” — It’s why you don’t see any consumer printers with that feature. Anyway, [Bryan] just sent us his upgrade to his Makerbot Replicator 1, and it’s a pretty slick system. His goal was to add the heated enclosure to the printer as unobtrusively as possible — no need for people to think his printer is an even bigger fire hazard!

The INFRA-NINJA — A PC Remote Receiver

F3GULGEHTOUJI73.MEDIUM

Laziness sometimes spawns the greatest inventions. Making things to reduce effort on your part is quite possibly one of the greatest motivators out there. So when [Kyle] had to get out of bed in order to turn off Netflix on his computer… He decided to do something about it.

He already had an Apple remote, which we have to admit, is a nice, simple and elegant control stick — so he decided  to interface with it in order to control his non-Apple computer. He quickly made up a simple PCB up using the good ‘ol toner transfer method, and then populated it with a Bareduino, a CP2102 USB 2.0 to TTL UART 6PIN Serial Converter, an IR receiver, a USB jack, header pins, and a few LED and tactile switches.

It’s a bit tricky to upload the code (you have to remove the jumper block) but then it’s just a matter of connecting to it and transferring it over with the Arduino IDE. The Instructable is a bit short, but [Kyle] promises if you’re really interested he’ll help out with any questions you might have!

A Different Kind of CNC Workpiece Clamp

7

[Mike Douglas] joined the world DIY CNC machining recently with a FireBall X90 CNC router. Instead of buying an expensive aluminum T-slot bed, he decided to try something we haven’t seen before…

His local hardware store sells aluminum bar clamps designed for clamping wood together — the best part? Only $10 each. What he’s done is added the bar clamps along the two sides of his bed, by adding plywood braces attached to the outside frame of the machine. He is losing a few inches of his usable bed area, but the added convenience of a quick clamping system is well worth it.

With the clamps in place, all he has to do is add two wooden braces (the black bars in the image above) to hold his work piece in place. This wouldn’t work very well for cutting metal, but this CNC router isn’t designed for that anyway.

Too bad he didn’t finish it sooner — it would have been a great entry for our recent Hackaday Hackerspace Henchmen CNC contest!

$20 GPS/GLONASS/Beidou Receiver

navspark

Sticking a GPS module in a project has been a common occurrence for a while now, whether it be for a reverse geocache or for a drone telemetry system. These GPS modules are expensive, though, and they only listen in on GPS satellites – not the Russian GLONASS satellites or the Chinese Beidou satellites. NavSpark has the capability to listen to all these positioning systems, all while being an Arduino-compatible board that costs about $20.

Inside the NavSpark is a 32-bit microcontroller core (no, not ARM. LEON) with 1 MB of Flash 212kB of RAM, and a whole lot of horsepower. Tacked onto this core is a GPS unit that’s capable of listening in on GPS, GPS and GLONASS, or GPS and Beidou signals.

On paper, it’s an extremely impressive board for any application that needs any sort of global positioning and a powerful microcontroller. There’s also the option of using two of these boards and active antennas to capture carrier phase information, bringing the accuracy of this setup down to a few centimeters. Very cool, indeed.

Thanks [Steve] for sending this in.

Build a Cheap Airplane ADS-B Radio Receiving Tracking Station

airplane tracking with ADS-B radio receiving

Do you have commercial or general aviation flying over your home or near your home? Would you like to know more about these airplanes: identity, heading, speed, altitude and maybe GPS data along with even more information? Well then [Rich Osgood] has just the project for you and it’s not that expensive to set up. [Rick] demonstrates using a cheap USB dongle European TV tuner style SDR (software defined radio) tuner that you can get for under $30 to listen in on the Automatic Dependent Surveillance-Broadcast (ADS-B) 1090 MHz mode “S” or 978 MHz mode “UAT” signals being regularly transmitted from these aircraft.

He steps us through configuring the radio to use a better antenna for improved reception then walks through detailed software installation and set up to control the radio receiver as well as pushing the final decoded data to mapping software. This looks like a fascinating and fun project if you live near commercial airways. You won’t need a license for this hack because you’re only listening and not transmitting, plus these are open channels which are legal to receive.

There are some frequencies you are not legally allowed to eavesdrop on—private communications for residential wireless telephones and cellular frequencies to name just a few (Code of Federal Regulations Title 47, Part 15.9). So remember you do have to be careful and stay within legal frequencies even if your equipment is not restricted from such reception. Also note that just because you have a legal right to intercept conversations or data on some frequencies it could be illegal to publicly share the intercepted content or any details on the reception or decoding (just saying for the record).

We wonder if [Rick] could partner with [G. Eric Rogers] to upgrade [Eric’s] motorized telescope airplane tracking system to extrapolate the radio telemeter data into vector data so his Arduino can track without relying on a video feed. That merger might just get them both on a short TSA list.

Join us after the break for some extra informational links and to watch the video on setup, installation and usage of this cheap airplane tracking rig.

A Vibrating Timepiece

vibratingWatch

It may not look like much, but the above pictured device is [qquuiinn's] handy little watch that indicates time through pulsed vibrations. Perhaps we should refrain from labeling it as a “watch,” however, considering it’s [qquuiinn's] intention to remove the need to actually look at the thing. Vibrations occur in grandfather clock format, with one long vibration for each hour, accompanied by one, two, or three short pulses for the quarter-hour increments.

The design is straightforward, using an ATTiny85 for the brains along with a few analog components. The vibration motor sticks to the protoboard with some glue, joining the microcontroller, a coin cell battery, and a pushbutton on a small protoboard. The button allows for manual time requests; one press responds with the current time (approximated, probably) in vibrations. The build is a work in progress, and [qquuiinn] acknowledges the lack of an RTC (real-time clock) causes some drift in the timepiece’s accuracy. We suspect, however, that you’d address that problem—twice daily—when you replace the battery: it only lasts ten hours.
