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 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!

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

3D Print Place

I received an email from some awesome people over in the Netherlands. They are launching a collaborative site which looks absolutely fun. Here’s the ‘meat’ of the email.

“My name is Danny and my associate’s name is Sebastian. We are two recent college grads who caught the 3D printing bug and believe that 3D printing is going to explode and revolutionize the way we live our lives. We can’t wait to see the transformation take place, so we setup 3D Print Place to help facilitate this change. 3D Print Place is designed to make 3D Printing more accessible to home users, academic institutions, and small businesses, by serving as a one-stop-shop for all your 3D Printing needs. The platform is entirely fueled by user-to-user collaboration – the community creates content and value, the website solely provides the necessary infrastructure to simplify user interaction. We recently launched to the general pubic at the 3D Printing Event ( in the Netherlands on October 25th and now are looking for enthusiastic people in the 3D printing community to help improve our project.

You can check out the site by clicking on the link below.

We are in the process of reaching out to hacker spaces, engineering programs, and tech clubs around the world and think that TheTransistor could get a lot out of our beta site. It would mean a lot to me if you could pass on this e-mail to members of TheTransistor and to anyone else that you think might be interested in this collaboration project.”

Good luck Danny and Sebastian, the project looks absolutely wonderful. :)

Hack This: 24 Incredible Hackerspace Projects from the DIY Movement

Hack This: 24 Incredible Hackerspace Projects from the DIY MovementI wanted to take a second to mention a fantastic book that was just released. This book has been “in the works” for about a year now.

The book is Hack This: 24 Incredible Hackerspace Projects from the DIY Movement by John Baichtal. It features 24 hackerspace projects and a few other sections on things like how to start your own hackerspace. It even includes a quick write up on theTransistor’s MAME cabinet.

Overall it really is a good book full of interesting projects from many hackerspaces. The best part is that right now you can pick up a copy over on Amazon for $15. I highly recommend this. :)

CANCELED: College of Lockpicking: September 17th

Sorry for the late update folks, but it appears that the people presenting the class have had something or other come up. I apologize to all that made plans to come down this weekend, we are hopeful that they will stop by in the future!

Eric from Pumping Station: One is coming down this coming Saturday (the 17th) to give a workshop on lockpicking. The class will be between $20 and $50 dollars (details below), and is open to all that would like to attend.

College of Lockpicking is a hands-on workshop that includes approximately an hour of instructor-led lecture and an hour of participant-led workshop, including the history and development of pin-tumbler locks, a full breakdown of how a pin-tumbler lock works, introduction and tutorial with the pick tools, and a slew of videos on bump keys, destructive entry methods, decoders, Medeco picking, electronic locks, bike locks, car locks, and more. In our experience, everyone opens a lock at College of Lockpicking!

Details are still being worked out, buy you can expect a $20 door fee, and 10-piece custom lockpick sets available for $30. Participants sign up prior to the event at an EventBrite page (link coming soon), where they can register for either the whole package, or just the door fee if they already have some lockpicks.

More details coming soon!

Make: Provo Monthly

Starting September Make: Provo will be a monthly only event. We will no longer be doing a weekly public night at that point. We have updated the website calendar to reflect this. (There will be a once-a-month public Make: Provo meeting the first Saturday of each month.)

Here are some of the reasons why we have decided to switch to this model:
*** It is a lot of work to host a public night every Saturday (even though we currently don’t do a whole lot, we still have to make sure we are there, the doors are unlocked, etc)

*** We would rather have one “big” night once a month then several small nights.

*** This will give us more time to concentrate on our projects so we can show them off on the Make: Provo meetings.

*** We would like to extend the hours that Make: Provo runs. (details on the calendar)

*** We would like to start providing a free public electronics / science / etc demonstrations each month. This will help with that as we need planning time. If you are interested in teaching a class / giving a demonstration please contact us via email or PM on the forums. (Details will be posted a month in advance on the calendar)

As an example Septembers Make: Provo will include a 30-60 minutes class/demonstration on using the TI TLC5940 ic. You are encouraged to bring a MCU and some LED’s if you would like to play with one of ours for a couple hours.

As a side note: we have a nice new public desk area set up for you to set up your projects, and we are working on getting computers at all 8 stations. (We do have additional seating as needed.)

Please send questions / comments to deven [at]
Please send all flames / spam to tim [at]

Thanks Again,
tT Staff
