Free Class: Who left the WPA2 backdoor open!?
2012/09/01 @ 8:30 pm – 9:15 pm

In a world where people always forget to secure their protocols, we find that nearly all home Wifi routers are vulnerable to a brute force attack agains the Wifi Protected Setup *feature*. This talk will discuss how WPS works and why its vulnerable. We will also walk through a demonstration of how to attack your neighbors for fun, no profit, and possibly jail time. Oh, and we’ll show you how to protect yourself, because that is whole point of this topic isn’t it?

**Bring your promiscuous wifi adapters and laptops**

Free Class: Bluetooth Sniffing, Very Possible and Cheap!
2012/09/01 @ 9:15 pm – 10:00 pm

Bluetooth packet sniffing is getting a makeover in the VERY near future. In the past, Bluetooth sniffing has never been an easy task for anyone who doesn’t have thousands of dollars to spend on equipment. However, these days, there is a project in the works that will likely put the power of bluetooth sniffing in the hands of those with just a couple hundred dollars.

It’s called the Ubertooth One. This presentation will discuss the current development of the Ubertooth One as well as how it can be used to sniff Bluetooth packets.

Member Responsibilities:
Be awesome
Be respectful
Clean up after yourself

Other Notes:
There has been some question over the differences between the two spaces. I will do my best here to explain this.
- Darlington is an extension of theTransistor in Provo. Darlington is focused primarily on electronics, computers, software, InfoSec, etc; while theTransistor has more room for public classes, band saws, drill presses, laser cutters, larger work areas, and more.
- While a membership at Darlington DOES give you full access to theTransistor in Provo you will not have the option of getting a desk at the Provo location; you WILL however get your own personal cubicle at Darlington.
- Membership at theTransistor is almost full and does usually come with a personal desk, however it does not guarantee you access to Darlington; as Darlington has limited space.
- Darlington is a quieter workspace (though you can decide to make it loud if the members there would like) while theTransistor tends to have a bit of a ‘buzz’ going on whenever there is a large group there.

Again if you have any questions, would like a tour of Darlington, or would like a membership ASAP please shoot an email over to: contact@thetransistor.com

TheTransistors Red Bull Challenge Entry

The Transistor recently (just a few days ago in fact!) entered in the 2012 Red Bull Creation Challenge. For this challenge we built a fully automated, pneumatic Can Dispenser, Drink Extractor, Drink Cooler, and Can Crushing machine. This ensures a constant stream of Energy Drinks / Caffeine for those late night projects at the hackerspace. ;)

The cans are loaded into the hopper (which holds roughly 16 cans) where they wait for you to press the dispense button. Once the button is pressed, all kinds of magic (errr science) happen. First a pneumatic ram drives a spear through the front-most can, causing it to drain into an aluminum pipe which is wrapped with 10 copper pipes that ice water is circulating through. This effectively cools the drink from room temperature to roughly 40 degrees or less in about 30 seconds (the time it takes the can to drain). From there your drink runs into another funnel and into your cup. Finally a second, larger pneumatic ram crushes the empty can and ejects it out the side. As the ram retracts, gravity automatically loads the next drink into place. (Thanks gravity!)

This project was completed over the course of 3 days. Video below. Thanks for watching!

CMKT 4 returns! Special classes open to the Public!

CMKT 4 returns to The Transistor, Provo’s Hackerspace Friday, May 25, 2012 7:00pm until 10:00pm!

Join the members of the circuit-bent rock band CMKT4 for a workshop on building your very own EconoMIC Bottle Cap Contact Microphone (from Creme DeMentia). CMKT4 will show you how to solder up a piezo-electric pickup and house it sturdily in a recycled bottle-cap housing of their own design! Stick around for a set from the band as the tool-handle dip on your freshly built contact microphone dries. Additional take-home kits and other surprises will be available, come build a mic and see and hear some of the circuit-bent instruments you’ve read about on www.GetLofi.com up close. Bring your own instruments and objects to amplify!


Build an EconoMIC Bottle-Cap Contact Mic with CMKT 4 $15

Circuit-bending rock trio CMKT 4 will help students build a sturdy, working piezoelectric pickup using components and recycled materials. The band will help you learn to solder and ensure your success in building the kit. The comic book instructions will help guide you through their special process of soldering, drilling, gluing, zipping, and dipping – Voila! You are the proud owner and maker of your very own EconoMIC Bottle-Cap Contact Microphone (from Creme DeMentia). This simple transducer will create an audio signal from physical vibrations – like an electric stethoscope! Stick around for a performance from the band while the tool-handle dip dries!

Circuit-Bending 101: Build a Bending Buddy $15

Circuit-bending rock trio CMKT 4 never want you to bend circuits alone – that’s why they’ve developed The Bending Buddy. Want to learn the basics of circuit-bending but don’t know much about electronics? Building a Bending Buddy will introduce necessary skills for circuit-bending – soldering, reading a schematic, drilling, mounting components, wiring. Once you’ve built your Bending Buddy, you’ll be prepared to embark on a journey of discovery, using it to probe battery-operated circuits and divine new sounds. The comic book instructions and informational packet will help you understand broader concepts of circuit-bending – different types of bends, understanding components, building simple control circuits, bread-boarding and proto-boarding.

Build Mr. Mixer $25

Circuit-bending rock trio CMKT 4 want to introduce you to their new friend, Mr. Mixer. Mr. Mixer is a simple 4 channel passive mixer built from components and recycled materials. Students will build Mr. Mixer from comic instructions with help form the band. Mr. Mixer will allow students to mix together different audio sources to a single audio signal. The kit also introduces students to the magic of CdS or Photo Cells, which translate light into resistance. The Photocells will act as faders on the mixer, allowing students to duck sounds in and out, changing their volume with light!

.:! YOU WILL REGRET IT IF YOU MISS THIS !:.

Free Class: Chip Amplifiers and Surface Exciters

Hosted by Alex and Zack. For the amplifier part of the class we will be giving a brief overview of the different types of electronic amplifiers. We will discuss the basic functions of several types of circuits, along with their pros and cons.

For the surface exciter portion of the class we will be talking about surface exciters [also known as tactile transducers]. These amazing little devices can turn most any surface into a speaker. We will talk briefly about how they work and will offer a demonstration of how they can be used to turn different surfaces into speakers.

The rest of the time will be used for kits assembly. Participants can choose to buy kits and assemble their own small amp. They will also receive a pair of 2 watt surface exciters for them to experiment with.

Kits will be provided for $30 and will include:
1x stereo amplifier kit
1x 6 foot 3.5mm stereo cable to connect their amp and audio source
2x 2 watt 8 ohm surface exciters
Please email Alex [at] thetransistor [dot] com to reserve your kit

Participants will need to supply their own audio source and 12v DC power supply that can supply at least 500mA (.5A) of current. If you do not have a spare one lying around your house, you can usually find one at a local thrift store for relatively cheap. The circuit is designed around a 12v power source, but theoretically can use a supply as high as 25v.

Check out this youtube video of the test circuit:

*note the final circuit uses screw terminals instead of spring terminals.

This is a FREE, public class. We will start at 7:30pm on Saturday, April 7th. You are welcome to sit in on the class without purchasing a kit if you would like. Please email Alex [at] thetransistor [dot] com to reserve your kit
