THP Hacker Bio: Peter McCloud

September 10, 2014 by Brian Benchoff 16 Comments

By far one of the craziest entries for The Hackaday Prize is [Peter McCloud]’s Goliath, an enormous gas-powered quadcopter. It weighs about 240 pounds, is powered by a 30 horsepower v-twin lawnmower engine, is lifted into the air with homemade props milled on a CNC machine. It’s a frightening build even when the engine isn’t turning. When running, it’s an awesome display of power and technology.

Goliath has had a few setbacks of late, snapping two composite props in its first attempt at hovering. This hasn’t deterred [Peter]; he’s picking up the pieces and he’ll have this monstrous quad hovering in a week or two. A good thing, because the judges are paring the quarterfinalists just three weekends from now.

Check out [Peter]’s bio below.

THP Hacker Bio: John Costik

September 9, 2014 by Brian Benchoff 6 Comments

A surprising amount of entries for The Hackaday Prize are medical devices, and the regulatory problems associated with that domain. [John Costik]’s Diabetes Data, Everywhere is one of the few projects that is perfect for a world where the words ‘hack’ and ‘FDA’ simply cannot be found in the same sentence.

[John]’s son was diagnosed with Type 1 diabetes at a very young age, and very early [John], his family, and the school nurse have had to deal with the nearly innumerable tasks that type 1 diabetes management entails. A Dexcom continuous glucose monitor is a big help, providing a wealth of glucose logging in a small, wearable device.

This monitor, however, is relatively locked down; the stock device is unable to push data to the Internet. [John] reverse engineered the protocol for this glucose monitor, enabling [John] to monitor his son’s blood glucose levels from anywhere on the planet.

There’s a huge community of people waiting for the technological advancements of the last thirty years, like the Internet and portable, networked devices, to make it into medical devices. [John]’s project has already gotten a bit of local news coverage, and is a perfect example of expanding the capabilities of existing devices to make his and his family’s life more convenient.

THP Semifinalist: Stubby, The Adorable Hexapod

September 8, 2014 by Brian Benchoff 18 Comments

After talking with a few of the judges for The Hackaday Prize, documentation will be a large factor in determining who wins and takes a trip to space, and who is left with their feet safely planted on the ground. Stubby the Hexapod is one of the most well documented projects in the running. There are already two hardware revisions for the walking mechanism, several board layouts for the controller, and more project log entries than you can shake a stick at.

Stubby is the brainchild of [The Big One] (a.k.a. [Wyatt] with [Warren], [Princess Sparkle], and [exot] filling out the rest of the team). The project originally began as an educational robotics project meant for teaching [Wyatt]’s kids the ins and outs of robotics and electronics. He’s doing this by developing an open source hexapod robot platform, complete with a frame, electronics board, and a lot of interesting code driving 18 hobby servos.

The frame for Stubby’s first hardware revision is rather interesting; it’s able to be reproduced with nothing more than a scroll saw. The latest revision is a complete rethinking of hexapod locomotion using 2DOF legs and a more mechanical gait.

Being completely open source and very well documented, you can already make your own Stubby hexapod with a scroll saw and the files on [Wyatt]’s site. If 3D printing is more your thing, there’s also a few files to help you with that.

You can check out a few videos of the different Stubby revisions below:

THP Hacker Bio: Michael R Colton

September 7, 2014 by Brian Benchoff 6 Comments

With many hackers out there realizing how much you can do with a few RF blocks connected to a computer, it’s no surprise software defined radio would make a showing in the semifinalists for The Hackaday Prize. [Michael]’s project is the PortableSDR, a small, self-contained unit that handles just about everything below 30MHz. No, [Michael] isn’t dealing with gigahertz accessible with fancier SDRs, but that’s not the point: PortableSDR is meant to do everything – vector analysis, a neat waterfall display, transmit and receive – in a small, portable package you can take anywhere. It’s also fairly cheap to build, and of course completely open source.

This isn’t [Michael]’s first rodeo; he’s built a number of equally cool projects before. He was kind enough to send in a short bio, available below.

THP Semifinalist: Secure Your Internets With Web Security Everywhere

September 6, 2014 by Adam Fabio 50 Comments

[Arcadia Labs] has created a great little device in Web Security Everywhere, a semifinalist in The Hackaday Prize. At the center of it all is UnJailPi, a Raspberry Pi device which can act as a secure router between a protected network and the unprotected internet. UnJailPi can create OpenVPN and Tor connections on the fly from its touch screen interface. The full details are right up on [Arcadia’s] Hackaday.io project page.

One of the most amazing things about the project is its creator, [Arcadia Labs]. [Arcadia] started from square one learning python just 1 year ago. Since then he’s become a proficient python coder, and created UnJailPi’s entire user interface with pygame.

[Arcadia] is also working with simple hand tools. He has no access to the CNC routers, 3D printers, or milling machines used in many of the projects we see here on Hackaday. All the work on UnJailPi’s acrylic case was done with a handsaw, a file, and a heck of a lot of patience.

Currently [Arcadia’s] biggest hurdle is finding a good power supply for his project. UnJailPi is designed to work both on AC or an internal battery. His current power circuit throws off enough heat that the Raspberry Pi resets while the battery is charging.

We’re sure [Arcadia] will figure out his power issues, but if you have any suggestions, leave a comment here, or head over to the project page and let him know!

The project featured in this post is a semifinalist in The Hackaday Prize.

THP Hacker Bio: Rusty Jehangir

[Rusty]’s project for the Hackaday Prize is extremely ambitious. He’s planning on sending an autonomous craft across the ocean, from LA to Hawaii, a distance that will end up being well over 2,500 miles The best part about this project? It’s already had some time in the ocean, cruising off the coast of southern California under its own power for a distance of 20km.

Why is [Rusty] doing this? Partly because he wanted to do something no one had ever done before. For him, this meant developing a cheap underwater thruster, building an autonomous solar-powered surfboard for a months-long voyage halfway across the Pacific. It’s a small step to the goal of exploring the deep ocean with his thruster and mostly off the shelf parts, but already [Rusty] has learned a lot about electronics in a marine environment and being confident enough to let a project go on its own for months at a time.

Extrinsic Motivation: An Open, Modular Effects Pedal

September 4, 2014 by Brian Benchoff 18 Comments

Microcontrollers and Arduinos are cool and all, but dealing only in the digital domain does have its limitations. In fact, most of your electron heroes didn’t begin their electronics career by blinking pins on digital outputs; they were solely in the analog domain with their radios and, yes, guitar effects pedals.

[Josh]’s entry for The Hackaday Prize was by far the most analog project of the entire contest. It’s an open source effects pedal that takes advantage of the modular design of the most popular pedals in history.

A good number of the famous circuits for turning an electric guitar into an aural experimentation are based on small circuit modules, packaged and repackaged again until the desired tone is achieved. [Josh] wants to pack these modules separately on different boards, specifically shields, although no Arduino is used, so any sound can be created.

Already [Josh] has done some research to determine what circuits and circuit modules to clone. The list should be fairly familiar to anyone with a pedalboard – Tube Screamers, Fuzz Faces, Big Muffs, and Phase 90s are at the top of the list. He may not get to the complicated digital effects like pitch shifters and digital delays, but it’s still a great project for experimentation.

You can see [Josh]’s project video below.

This project is an official entry to The Hackaday Prize that sadly didn’t make the quarterfinal selection. It’s still a great project, and worthy of a Hackaday post on its own.
