Metalab Promo Video means we need you to donate a camera.

HacDC needs a video camera.  The Metalab,  our fellow hackerspace in Vienna,  keeps us amazed with projects like this: [vimeo 1307809] We cannot let this go unanswered!  Donate to HacDC and help us score our own video camera!   Just think about all the video blogging possibilities! Even if you can't support this particular effort, you can help us choose the right camera.

AVR Microcontroller Class: Columbus Day Edition

Folks hard at work in the space In honor of Columbus Day, the AVR class took a night off from "formal" instruction and messed around with noisemakers.  Specifically, using analog-to-digital conversion techniques to control the pitch of a square wave run through a small speaker.  Hilarity ensued.  (Follow along with us at the

Build a Brain Machine with Mitch at HacDC!

Mitch

Mitch Altman, microcontroller hacker extraordinaire and inventor of wonderful gadgets like the TV-B-Gone will be at HacDC on Sunday, September 7 at 2:00 PM to help show you how to build your own Brain Machine. Mitch will be bringing all the parts, tools and inspiration necessary, all you need to do is show up!

The event is free and open to the public, however, if you want to build your own Brain Machine, bring $25 to cover the cost of the kit.  (HacDC will be purchasing some kits you can help build if you don't want to take one home.)

Bre Pettis is one hot Brain Machine wearing hacker!

We are more than our credit scores

The truth is, we are more than our credit scores.  Who gave 3 companies the right to use secret calculations to determine if we qualify for credit, for a job, or even renting a house.  We did.  Credit scores are used everywhere as a standard measure of character.  But the truth is, humanity can't be summed up by looking at open lines of credit and how close you are to your credit limit.  Did using your credit card to replace your fridge for your family devalue you as a

Multi-Touch Display Interface Meeting

We're having our first meeting, to discuss the roadmap for the multi-touch interactive display (MTID), on Wednesday July 30th at 7:30pm.

Hacking the SmarTrip - Part I

Thanks to DCist - http://tinyurl.com/5spogg - I got inspired to rip apart an extra SmarTrip card I had lying around for when friends/family visit me in the D.C. area. Unfortunately for them, they will now have to buy the day-long pass until I am done playing! To start, today I took the extra card and soaked it in acetone for about an hour and after that time I was able to rip off the initial plastic of the card.

Multi-Touch Display Interface

The latest rage in computer user interfaces is known as 'multi-touch'. Multi-touch is essentially a touch screen and software that recognizes multiple simultaneous touch points. Multi-touch provides a radical interface and opens up a new ecosystem of computing applications that do not rely on a separate mouse or keyboard. Probably the easiest method for building a multi-touch interface is to take advantage of a property known as Frustrated Total Internal Reflection (FTIR).

Door Unlockerator Project

Last night, Ash came to the meeting with an RFID reader and a couple cards and an idea to turn it into an automatic door locker/unlocker by hooking it up to a motor and a small microprocessor. I liked the idea enough to toss it up as a project. The reader speaks 2400 baud 8N1, so it's a piece of cake to interface, and the cards are only $1.19 each.

HacDC: Python Sprint Project

Project PSP: (Sony please don't sue me, or place another DRM trojan in my stuffs) Alright, so hopefully we will be posting soon about the success of our parts party we had on Sunday, I met so many very cool people and we've received the warmest welcoming I could have ever hoped for, for that I am appreciative. Now to the fun: So during the party I spoke to a few people about Python (the latest in my language love) and someone informed me about the idea of having Python sprints, which essentially from what I understand (feel free to send hate mail if I get this wrong or offend any hard core
