$50k In Play: Awarding 65 Stickvise This Week

May 28, 2015 by 11 Comments

Pushing your circuit boards around the bench while trying to solder the components is a fools game. Clamp that board in place with a Stickvise you won from Hackaday! This week we’ll choose 65 projects to receive one of these PCB clamps. You must submit your project as a Hackaday Prize entry to be eligible. Do it now and you’ll be considered for our weekly prizes all summer long — they total $50,000 that we’re putting into your hands.

We’re particularly proud of the Stickvise story. It was posted as a project on Hackaday.io and immediately caught our eye as an interesting idea. We worked with [Alex Rich] as he made his way through the process of getting it ready for manufacturing and it just became available in the Hackaday Store.

Regarding your entry to win one: find a problem facing your community and start a project that helps to solve it. We’ve seen many great entries so far, but with so many prizes your chances of winning are still really good! We recommend adding a project log each week that discusses your progress and perhaps mentions what you would use the Stickvise for while progressing toward a working prototype. Even if you don’t think your idea can win one of the big prizes, a great idea and solid write up is definitely a contender for our $50k in Play weekly prizes. Just look at the projects that won last week:

Last Week’s 20 Winners of a Bulbdial Clock Kit

bulbdial-clock-50k-in-play-prize-blogview

Congratulations to these 20 projects who were selected as winners from last week. You will receive a Bulbdial Clock Kit. It takes the concept of a sundial and recreates it using different colors of LEDs for each hand of the clock. This is our favorite soldering kit. It ventures a bit away from our mission of awarding tools and supplies to help with your entry, but sometimes you just need to have some fun!

Each project creator will find info on redeeming their prize as a message on Hackaday.io.

Hackaday Prize Entry: An Electric Vehicle From Recycled Parts

May 27, 2015 by 49 Comments

In the future, just about everyone will be driving an electric car. We’re seeing the beginnings of this, and that means electrics and hybrids are showing up in junk yards. What does that mean? Tons of big batteries and powerful motors to build an electric vehicle from recycled parts.

A few years ago, someone exceptionally smart did the math on the environmental friendliness of different makes of vehicles from cradle to grave. The most environmentally friendly car to buy wasn’t a Prius, Leaf, or Tesla, but a used car; an old Civic or Rabbit. The logic makes sense – after two or three hundred thousand miles under its timing belt, the Civic or Rabbit has already paid the cost of forging the body and refining the plastic. Obviously, then, the most environmentally friendly car would be reusing the batteries and motor out of a newer hybrid.

For his Hackaday Prize build, [mauswerkz] is taking a 2001 BMW 330ci coupe and replacing the motor and transmission with some salvaged EV equipment. In this case, it’s the transmission and inverter from a Lexus GS450h and the batteries from a Chevy Volt ‘Extended Range’. Where the magical junkyard [mauswerkz] is pulling this equipment out of is anyone’s guess, but he did it. Maybe you can too.

So far, [mauswerkz] has the charger out of the Chevy Volt hooked up to the inverter and transmission from the Lexus and is making stuff turn. It’s only running at 200V instead of the final voltage of 650, but it’s enough for a proof of concept. Now it’s just a matter of stuffing everything inside the BMW.

Of course going to a junk yard isn’t the only way to get an EV. The more enterprising builder might want to build their own EV completely from scratch, starting with a block of foam. Yes, it even looks better than the BMW.

Hackaday Prize Worldwide: Shenzhen

May 27, 2015 by 11 Comments

That’s right, we’re headed to the epicenter of electronics manufacturing next month: Shenzhen, China. We have a ton planned and this is the quick and dirty overview to get you thinking. If you are in the area (or are itching to travel) join us for a week of hardware hacker culture. Highlights for our tour include:

  • Meet Up on June 18th – (RSVP details coming soon)
  • Zero to Product PCB Workshop on June 19th – RSVP Now
  • Hackaday Talks presented at Maker Faire Shenzhen on June 19th and June 21st
  • Hackaday Booth at MFSZ on June 20-21

Zero to Product Workshop at MakerCamp Shenzhen

shenzhen-makercamp-drawingMakerCamp brings 30 talented Makers, Hackers, Designers, and Engineers together for a few days to build a makerspace inside of a shipping container.

We won’t be part of that build team (registration is open until 6/1 if you want to be). We will be supporting the event as part of the workshops that help celebrate the completion of the space. A mobile hackerspace full of interesting tools is one thing. But the sharing of knowledge, experience, and skill is what truly makes a hackerspace work.

zero-to-product-workshop-LAOur Zero to Product workshop created by [Matt Berggren] has been generating a ton of buzz and will be offered at Shenzhen MakerCamp.

RSVP for the Workshop

The workshop runs from 10am to 6pm on Friday, June 19th on the grounds of Maker Faire: Shenzhen. The event covers PCB design and at the end you will have laid out a development board for use with the ESP8266 WiFi module.

We were totally sold out for the workshop in LA a few weeks ago this is another chance to join in. If Shenzhen is a bit too far for you to travel, we are also planning the next installment in San Francisco on June 13th.

2015-bamf-meetupHackaday Shenzhen Meetup

If you just want to hang out, so do we! On the night of Thursday, June 18th we’ll be rolling into an area bar for a tasty beverage and a night of interesting conversation. As always, we want to see the hardware you’ve been working on. We do recommend bringing things that fit easily in your pocket or backpack since we’re meeting up to spend some time with other Hackaday community members in the area.

We don’t have the location nailed down for this one. Check this post again as we’ll be adding it here. And if you have a bar to suggest to us please leave a comment below.

The picture above is from just a few weeks ago. We had a huge turnout for the BAMF meetup. There was a ton of hardware on hand which makes for really easy conversation as you meet other hackers for the first time.

Talks by [Mike] and [Sophi] plus Booth at Maker Faire Shenzhen

[Mike] is giving a talk on Friday, June 19th about the power of Open Design to move education forward. [Sophi] will be presenting her talk on Sunday, June 21st about making stuff that matters and working on research equipment used to investigate the world around us such as solar, medicine and disease.

Come to the Faire to hear our talks, but make sure you swing by the Hackaday booth as well. We’ll be bringing some of our most favorite projects to exhibit but we can’t resist the opportunity to do something interactive. Stop by and build an oscillator, wire up a sequencer, and create your own rudimentary music based on [Elliot Williams’] series Logic Noise.

Tag Along with Hacker Camp Shenzhen?

hcsz2015-thumbnailOne of the adventures we’ve always wanted to take part in is Hacker Camp Shenzhen which is run by Hackaday alumnus and Hackaday Prize Judge [Ian Lesnet]. The week-long camp leverages [Ian’s] knowledge of the area, manufacturers, markets, and people to provide tours and workshops for those interested in manufacturing. It just so happens that HackerCamp lines up the same week as all of the Hackaday events. We can’t take part in the entire thing, but are hoping that we have a free day to meet up (and possibly tag along) with the HackerCamp crew.

Hackaday Prize Entry: Telling Dad The Stove Is Off

May 26, 2015 by 5 Comments

A month ago, Hackaday landed at the NYC TechCrunch Disrupt, a bastion of people up all night on MacBooks and immense amounts of caffeine and vitamin B12. For 20 hours, everyone was typing away trying to build the next great service that would be bought by Google or Amazon or Facebook. Tucked away in one small corner of the room was the Hackaday crew, giving out dev boards, components, and advice to the few dozen hardware hackers at Disrupt. [David], one of these Hackaday enthusiasts won the Twilio Sponsorship Prize at Disrupt, and now it’s a Hackaday Prize entry.

[David]’s dad has a little bit of paranoia of accidentally leaving the stove on. This usually manifests itself a few minutes after leaving the house, which means turning the car around just to make sure the stove was off. At the TechCrunch hackathon, [David] built a small IoT device to automatically read the temperature of the stove, send that off to the Internet, and finally as an SMS via Twilio.

The hardware [David] is using is extremely minimal – a thermopile, a gas sensor, a WiFi module, and a microcontroller. There’s a lot of iterations in this project, with [David] looking at everything from TI MSP430s to Teensys to Arduinos to ESP8266 modules. Still, rough prototype thrown together in 20 hours is all you need to win the Twilio prize at Disrupt, and that’s more than enough for a very good Hackaday Prize entry.

The Hackaday Prize: An Ultra Low Cost 3D Printer Controller

May 25, 2015 by 29 Comments

This isn’t a Hackaday Prize entry that will change the world, but that doesn’t mean there’s not a place for it. [vdirienzo] is building an ultra low-cost 3D printer controller for 3D printers and other CNC machine. It’s not going to change the world, but it is a rather interesting little device.

This printer controller is very minimal, with a single-sided circuit board with just enough parts and components to make this board useful. The stepper motor drivers are from Pololu, and most of the other components are stuff you could pull out of a reasonably stocked junk drawer. The microcontroller is rather interesting; it’s an Arduino Nano. Instead of the ATMega644 and ‘Mega1280 microcontrollers found on other 8-bit printer controller boards, [vdirienzo] slimmed down the Teacup firmware to fit on the ATMega328 in the Arduino Nano.

The SinapTec is not by any means the first effort to create an ultra low-cost controller board for a 3D printer that can be assembled at home. The RepRap Gen 7 electronics can be manufactured on a RepRap or small CNC mill. There’s not much to these boards – just a small, single-sided board. If you want a small, simple, and cheap controller board for a 3D printer, this is all you need.

While a cheap 3D printer controller board doesn’t really fit with the ‘change the world’ theme of The Hackaday Prize, that doesn’t mean there’s still not a place in the contest for [vdirienzo]’s entry; we have a Best Product category, with a $100k prize and a six month residency in the Hackaday Design Lab. If that’s not enough reason to build something cool – even if it won’t change the world – we don’t know what is.

Hackaday Prize Entry: The Chocometer

May 24, 2015 by 44 Comments

Diabetes affects almost 400 million people worldwide, and complications due to diabetes – blindness, cardiovascular disease, and kidney problems – can be reduced by regular monitoring of blood glucose. The usual way of measuring blood glucose is with a pin prick of blood and a small test strip that costs about $0.30. That’s a lot of test strips and blood used by 400 million diabetics every day. Wouldn’t it be better if there was a less invasive way of measuring blood glucose?

[marcelclaro]’s project for The Hackaday Prize aims to do just that. Instead of measuring blood directly, his project will measure blood glucose by shining light through a finger or an earlobe. Using light to detect blood glucose is something that has been studied in the lab, but so far, there aren’t any products on the market that use this technique.

There are two major problems [marcel] needs to overcome to turn this project into reality. The first is simply raw data for calibration. For [marcel], this is easy; he has Type 1 diabetes, and takes four glucose measurements a day. Patient heal thyself, or something.

The second problem is getting a photosensor that’s sensitive enough. By using an InGaAs PIN diode, a current-controlled oscillator, and a digital counter, [marcel] should have a sensor that’s good enough, with electronics that are cheap enough, to create some tech that is truly game changing for a few hundred million people around the world.

Hackaday Prize Entry: Arduino MPPT Controller

May 23, 2015 by 17 Comments

Imagine you’re building a small solar installation. The naive solution would be grabbing a solar panel from Horror Freight, getting a car battery and AC inverter, and hoping everything works. This is the dumb solution. To get the most out of a solar you need to match the voltage of the solar cell to the voltage of the battery. How do you do that? With [Debasish]’s entry for The Hackaday Prize, an Arduino MPPT Solar Charge Controller.

This Maximum Power Point Tracker uses a buck converter to step down the voltage from the solar cell to the voltage of the battery. It’s extremely efficient and every proper solar installation will need a charge controller that does something similar.

For his MPPT, [Debasish] is using an Arduino Nano for all the math, a DC to DC buck converter, and a few MOSFETs. Extremely simple, but [Debasish] is connecting the entire controller to the Internet with an ESP8266 module. It’s a great example of building something for much less than it would cost to buy the same thing, and a great example for something that has a chance at making the world a little better.
