I'm proud to present my latest creation: The Hammer! The Hammer is a prototype test-your-strength game that's an insertable, muscle-controlled, light-up dildo. Update, 1/5/13: The Hammer has been listed as Cracked.com's #1 Geekiest Sex Toy! Welcome, everyone!

Like innovative sex/kink-positive projects? Maybe you have an idea of your own, but need to raise some money? Check out my new startup, Passionate Produce!

Update #1, 10/11/12: If you would like to hear me talk about how I made The Hammer, you can see some excerpts and my slides from my technical talk at Arse Elektronika 2012.

Update #2, 10/11/12: The Hammer + animated GIFs = Win!

Update #3, 1/5/13: See The Hammer in Person! (Ignite Craft Boston, Arisia)

The TLDR:

Since I was young, I've wondered what it would be like to have a bio-cock. Unfortunately, this is an experience I am unlikely to have. It's at least some consolation that now I have the most beautiful, glowing, rainbow penis in the world.

I've been working on The Hammer for a couple of months. It contains two force sensors, a strip of individually addressible RGB LED's, and an accelerometer. It connects to a custom-built prototype Arduino shield, and I programmed it using the Arduino software development environment. The toy itself is made of platinum cure, body-safe silicone.

I originally named it after a Test-Your-Strength game in the Musee Mechanique in San Francisco. I then realized:

When all you have is a light-up cock, everything looks like it needs to be nailed. The Hammer is my penis.

Receive visual feedback for Kegel exercises or physical therapy

Have a lightsaber duel

Get a blowjob or handjob in the dark

Watch the Hammer change color as you orgasm

...or anything else you can program!

Right now The Hammer has two modes: the test-your-strength game, where the more you squeeze, the more it lights up; and a demo mode which cycles through all of the colors of the LEDs. Soon I hope to connect the Arduino to my Android phone, and then I'll be able to do even more cool things!

I'll be following up on this with more technical details over the next few weeks. (Update, 10/11/12: If you would like to hear me talk about how I made The Hammer, you can see some excerpts and my slides from my technical talk at Arse Elektronika 2012.) My plan is for The Hammer to become an Open Hardware project. This is still very much a prototype, but I would be thrilled if anyone else wanted to build their own.

I'd like to thank Jimmie Rodgers, my friends at Artisan's Asylum, and the teasecraft-boston meetup group for all of their help, ideas, and encouragement! I'd also like to thank Monochrom for giving me the opportunity to present this project at Arse Elektronika 2012.

What's my latest and greatest endeavor? I'm launching Passionate Produce, a new sex/kink-positive crowdfunding startup. Is this relevant to your interests? Subscribe to my newsletter!
