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

Free Class: Introduction to DipTrace

Hosted by Tim Anderson and Devin Hales. This class will cover designing PCBs and Schematics in the Diptrace Software including importing and making new components and patterns,
setting up and enforcing design rules, considerations for manufacturing, gerber file generation and more. The class will cover
these topics through the design from the ground up of an FTDI breakout board.


P.S. Feel free to bring down a laptop (we will have WiFi and Power) to follow along.

This is a FREE, public class. We will start at 6:30pm on Saturday, April 7th and should run 1 hour.

Free Class: Composite Materials and Laminates

The Transistor will be holding an entry level class on plastic reinforced fiber laminates. The class will cover construction of basic structures, mold preparation, and vacuum bagging. We’ll also be talking about mechanical properties, different kinds of composite materials, the benefits of composite structures, as well as cutting and machining difficulties. Kits will be provided for $20. Kits will include resin, carbon cloth, 2 kinds of glass fiber cloth, vacuum bagging materials, and other items necessary for laying-up a 5 inch square laminate.

Please send an email to Clay [AT] thetransistor [DOT] com if you would like to reserve a kit.

Note: The resins we will be using will more than likely ruin any clothing they come into contact with, dress accordingly.

This is a FREE, public class. We will start at 6:30pm on February the 4th.

Free Class: 2.4GHz biquad antennas

We’re doing a class on 2.4ghz biquad antennas and that there will be kits available. Each kit will consist of the hardware to make the actual antenna, and one satellite dish. We won’t include any cables or adapters in the kits at this point. An update with the price of the kits will be posted soon.

This is a FREE, public class. We will start around 5:00pm on January the 7th, and should run between 30-60 minutes.

Make: Provo is held the first Saturday of each month, unless otherwise noted. It runs from 4:00pm-10:00pm. We try to offer a free class each month. Bring your projects to show off and your questions to ask.

Free Class: Introduction to Oscilloscopes

This coming Make: Provo (October 1, 2011 @ 4pm – 10pm) we will be giving a quick class on the basic usage(s) of the ever popular tool, The Oscilloscope.

This is a FREE, public class. We will start around 6:30, and should run between 30-60 minutes. We will have two oscilloscopes left out for the public to play with when we are done.

If there is interest we may do some additional classes on more advanced oscilloscope usage.

(And join us in November for our CNC machine basics class where we will cover 3d printers and cnc routers!)

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

Make:Provo Reminder

Just a friendly reminder to everyone that we are now holding a Make:Provo meeting every Saturday from 4PM to 8PM, followed by Game Night until we feel like going home. Be sure to check the Calendar page for any last minute changes to hours or scheduling before you come down. Everyone is welcome, so bring your projects, ideas and friends down to meet with your local hacker/maker community. We already had a couple new faces last week, and hopefully we’ll see many more in the future.

Below you should find posts of our more memorable moments as we ended 2010 here at the Transistor. We look forward to another great year of projects, making hacking, and having a jolly good time, and we hope you’ll all come down and be a part of the wonderful Utah hackerspace scene. Also, keep an eye out for an update in the near future about our recently completed MAME cabinet design and build. We’ll be posting our plans so you can make one too!
