Most of the hacks we see hitting the tip line are exactly that – hacked up hardware projects held together with hot glue and duct tape. [x-labs]’ entry for the 2015 Hackaday Prize, the UV badge, is certainly not one of these projects. It’s a professional one-off, capable of displaying the UV index, temperature, humidity, and pressure in one tiny little enclosure.
The UV badge is designed to be used outdoors. This means any old display ripped from a Nokia phone won’t do; that will wash out in the sun. Instead, [x-labs] is using a very sunlight-readable Sharp Memory LCD. A nice choice, as it’s an exceptionally low-power device.
Inside the 54 x 34 x 7.1 mm 3D printed enclosure is a very thin PCB, and all surface-mount components. The device is powered by a single coin cell battery that should give months of run time.
With a product designed so well, we’re wondering if the UV badge will be in the running for the Best Product category of the Hackaday Prize this year. There aren’t many projects in the running, and the winner gets a enough funding, machinery, and experience to turn their project into a product.
Take a look at some old electronics magazines, or even a few blog posts from 10 years ago, and you’ll notice something strange: parallel ports. Those big ‘ol DB25 were the way to get bits out of a computer and into a microcontroller. There was a reason for this: it was exceptionally easy to do.
Now, we have USB to deal with, and that means VIDs and PIDs, drivers, enumeration, and a whole bunch of cruft that makes blinking an LED a surprisingly complicated process. [Colin O’Flynn]’s project for the 2015 Hackaday Prize aims to fix that with BSU – BS Free USB.
Instead of USB to serial chips attached to another microcontroller, [Colin] is using a few microcontrollers with a built-in USB interfaces. These chips are loaded up with firmware and controlled with a simple API on the computer side. If you want to blink a pin, just add a library to your project and set the pin high. Want some SPI on your computer? That’s just setting a few pins as MOSI, MISO, and SCK and typing in a few bytes. It’s basically a $2 Bus Pirate that you can stick into any project.
If [Colin]’s name sounds familiar in the context of The Hackaday Prize, it’s because he won second place with the ChipWhisperer last year. While a tiny USB thing isn’t quite as cool as a tool to break embedded encryption, the BSU certainly seems more useful to millions of hardware tinkerers around the world.
This week we’re awarding a LightBlue Bean board to 50 projects entered in The Hackaday Prize.
We love this little board so much we put it in our store. It brings a microcontroller that has plenty of room and peripherals (and is quite well-known… the ATmega328) with the connectivity of Bluetooth Low Energy. If you’re planning on building something that needs processing power and connectivity with smartphones this is a good place to start. And this week you might just score one as part of the 2015 Hackaday Prize.
We’ll be looking for entries that are getting ready for the physical build and need connectivity. The best way to let us know your project should be one of the fifty winners is to post a new project log with your construction plans and how the Bean (or BTLE) would fit into that plan. Submit your build by next Wednesday (5/6) and you’re in the running!
We’re giving away $50,000 in prizes, 1/10 of the total Hackaday Prize pool during the build phase going on right now.
Last Week’s 30 Winners
Last week we were looking for great entries in need of circuit boards and boy, did we find a lot of them. Judging is super hard. We looked at all the entries and ended up with these 30 winners. Each will receive $50 to use for custom PCB manufacturing from OSH Park. We expect to see a lot more purple boards popping up on entry pages in the coming weeks! Congratulations to all winners. Each project creator will find prize info as a message on Hackaday.io.
Want an impressive example of what a few people can do in a garage? How about building an electric car, from scratch, starting with a gigantic chunk of foam?
The Luka EV from [MW Motors] had a few project aims: it should be all-electric, naturally, with a top speed of 130km/h or 80mph. It should have a range of over 300km, and it should look good. That last line item is tricky; it’s not too hard to build an electric car, but to make one look good is a challenge.
The design of the car actually started out as a digital file. A large block of foam was acquired and carefully carved into the desired shape. This foam is covered fiberglass, and parts are pulled off this fiberglass mold. This is a great way to do low-volume production – once the molds are complete, it’s a relatively simple matter to build another body for a second Luka EV.
With all the lights, accessories, windows, and trim installed, it’s time to put this body on a chassis. This was welded out of square tube and serves as a test rig that can be independent of the mess of fiberglass. In the chassis are batteries, suspension, motor controllers, and wheels loaded up with hub motors. It works well, even with one motor.
There’s a lot more to this project, including a great guide on building a road legal car in the UK. The team isn’t based in the UK, but it’s a much more friendly environment for ‘small series’ vehicles. The requirements are easy to meet – “have a horn”, for example – but there are a lot of them.
Already the car is beautiful, and that’s just with it sitting on a trailer. We can’t wait to see this thing hit the road.
This year’s Hackaday Prize is heating up, and right now there are quite a few projects in the works covering domains that are rarely, if ever, seen coming out of a garage or a workshop. One of the most interesting is [Glenn Powers]’ Open Ground Penetrating Radar. It’s exactly what the title says: an open-source radar system that can see into the Earth for less than $500.
While ground penetrating radar is great for archaeology and people searching for hoards buried in the middle of farmland, the biggest application is safety. You need only to Google “Florida sinkhole” to see the value of peering into the Earth.
[Glenn] is building his ground penetrating radar with a bare minimum of parts. A Baofeng VHF/UHF My First Radio™ serves as the signal generator, the controller is just an optoisolator, and the switch controller is a 7404 hex inverter. It literally can’t get simpler than that.
Of course these components can only be assembled into a simple radar, and the real value of a ground penetrating radar is the ability to map an area. For that, [Glenn] is bringing out a Pi and a GPS dongle to control the whole thing. Visualization is provided by none other than the US Navy. If it works for submarines, it should work for a metal cart, right?
It’s a great project, not only in the fact that it could help a whole bunch of people, but as a prime example of doing so much without tens of thousands of dollars in test equipment.
This week we’re giving away $1500 in OSH Park codes to thirty different projects. Submit your project to the 2015 Hackaday Prize now!
$50,000 over the next 17 weeks!
For each of the last four weeks we’ve awarded prize packages to three projects just for submitting ideas. Now it’s time to crank up the rewards. Over the next 17 weeks we will give away $50,000 in prizes. We’re kicking off the week by giving $50 OSH Park codes to 30 different projects.
Of course this is just the tip of the iceberg. This year’s prizes total half a million dollars, with a trip into space for the Grand Prize winner and $100,000 for the Best Product prize. Sitting this one out would be a huge mistake!
You need to post your project on Hackaday.io and officially submit it to the 2015 Hackaday Prize, which means clicking the “Submit-To” button on the left sidebar of your entry (shown below). You can confirm that you’re in the running by looking for the 2015 Hackaday Prize logo on your project gallery picture. Here you can see [castvee8] has submitted the Binary fuel tank, do you think it’s ready for a custom PCB?
To give yourself the best chance at winning, publish a new project log this week that outlines the PCB work your want to do for the entry. We’ll be looking for those as we judge the prizes that are most ready to begin (or advance) their hardware build.
OSH Park offers double-layer boards for $5 per square-inch and you get 3 copies of the board with shipping included. This $50 prize will land you quite a bit of board space. Get started now, you need to have your projects submitted by the morning of Wednesday, April 29th.
Canada! Just in time for Spring to hit. I went to Toronto to speak at FITC, an arts and technology conference, co-host a Hackaday meetup with HackLab TO, visit the DigiPlaySpace at TIFF, and to check out Globacore’s new digs.
FITC is a conference which celebrates the creativity in technology. Pictured above is Diorama Rama designed by [Christopher Lewis] and [Creative Technologists of Toronto] and built over 4 days by participants at FITC. The buildings are laser cut paper, and participants create a simple circuit using an ATtiny. A message is coded into the chip in ASCII and the buildings blink an individual message back in Morse code, each building blinking a different message. It’s pretty interesting to use a Morse –> ASCII phone app (Morse Tools) to read the messages.

Hackaday Prize judge [Micah Elizabeth Scott] gave a talk about her work. [Jessica Rosenkrantz] of Nervous System spoke about her company’s process when designing mathematically based objects. She spoke about her 3D printed dress pictured below and how it was made. Amazing! I also got to show off my newly minted Breathe project at FITC.

After FITC ended, HackLab co-hosted a meetup with us. A team from HackLab was a 2014 Hackaday Prize Semifinalist and won $1000 in components with their Retro Populator, a Pick and Place machine retrofit onto a 3D printer. We had beer as well as almond-cream flavored non-alcoholic drinks from the Luma Droid, a drink mixing robot. HackLab is a good-sized hackerspace, with a huge room for a meetup, a full kitchen and vegan dinner served frequently, plus a shop tools room all by itself.

Among the lightning talks, [Pearl Chen] brought her Intel Edison-powered alarm clock that has but one function — to tell her when she is running late. [Johannes van der Horst] brought a USB current monitor that had many of us fascinated for about an hour at the end of the evening, plugging in a phone or a battery just to see the numbers climb. [Eric Boyd] talked about the DIY Bio projects that are going on at HackLab. They are testing meat using PCR to see if it is indeed, beef. Ew.
[Andrew Kilpatrick] of Kilpatrick Audio showed us an older version of his synthesizer before showing us his newest revision, Phenol, which looks pretty slick.

[Hugh Elliot] spoke about a light-photography project. [Leif Bloomquist] spoke about a gaming glove project that Hackaday had previously covered. Leif had a Commodore 64 with him and all the games on it fit into 1 GB! [Nadine Lessio] discussed how many programs claim that you can become an expert in a few hours, but in fact, things are not easy. [Jay Vaidya] showed us an IFTTT hack which controls heaters and AC. [Andy Forest] showed us an impressive interactive model of Ontario’s power system that kids at Steam Labs created.

My final stop on this tour was to visit Globacore’s new offices. We spent a day or so hacking on a VR controller for their newest game called Power Cube. Power Cube is an Oculus Rift experience with a custom game controller holding an accelerometer, a gyroscope and magnetometer that links into the game directly.
