Learn to make physical audio loops with used cassette tapes! No experience needed. For the workshop we’ll be using cassettes with screws in the corners, which are easier to take apart but less common than the ones fastened with glue. We'll have regular cassette tapes for $1 each if you want to keep experimenting at […]

We’re making guitar-playing robots with Pi Pico microcontrollers and 360° servo motors! We'll provide soldering irons and supplies. To complete this workshop you'll need to buy a kit for $10. Here's what's included: • RP2040/Pi Pico board • 360° servo motor w/ attachments & screws • tiny screwdriver • micro USB cable w/data • 6 […]

Join us for another beginner-friendly soldering project at Iffy Books! You'll assemble a DIY audio meter kit, which you can use to visualize an audio signal's amplitude. To complete this project you'll need to buy a kit for $7.95. We’re suggesting a $5–$20 donation for the class, no one turned away for lack of funds. […]

Join us for a relatively quick and easy soldering workshop, suitable for total beginners! You'll strip some wires and solder 1/4-inch plugs to the ends, creating your own guitar cable. You can get a kit with 6 inches of cable for $4.25, or 4 feet for $13.50. We're suggesting a $5–$15 donation for the class, […]

Learn to make a programmable game timer and dice with a Pi Pico microcontroller! First you'll solder six LEDs, two switches, and a vibration motor to the board's GPIO pins. Then you'll install and customize the CircuitPython code that makes it work. No experience needed! You'll need to buy a kit for $9 to complete […]

Come out and get some soldering practice! This time we're making a heart-shaped board with 22 LEDs, using an oscillator circuit to dim and brighten them at the speed you choose. This project is ideal for folks who have soldered at least once before. Beginners are welcome to join us, but it may take you […]

Join us and build a tiny solar-powered square wave generator on a breadboard. No soldering required! The workshop is free to attend, but you'll need to purchase a kit for $12.50 to complete the project. Here's a link to the how-to zine we'll use. And here's a diagram of the oscillator circuit we'll build: Register:

Create your own digital audio sampler using a Pi Pico clone board! This project requires some soldering. It's recommended for folks who have soldered once or twice before, but beginners are welcome too. For the programming portion, you can bring a laptop or use one of our lab computers. You'll need to buy a kit […]

Charging your phone in a public place can be stressful. What if someone is collecting your metadata for marketing purposes? What if they're copying your files or installing malware? A USB data blocker can help! It's a little adapter with the data terminals left disconnected, so you can charge your phone anywhere without fear. This […]

Come out and get some soldering practice! This time we're assembling a short-range FM transmitter kit with a built-in mic and a 1/8" audio input jack. This project is recommended for folks who have soldered at least once or twice before. If you're brand new to soldering, we recommend taking a beginner class first. Register: […]

If you're interested in learning about wi-fi and Bluetooth networking but can't justify buying a Flipper Zero, this workshop is for you! Ghost ESP is a network analysis/testing tool that can run on a low-cost ESP32 microcontroller, as well as variants including the ESP32-C3. Ghost ESP offers wi-fi scanning, custom SSID beacons, captive portal mode, […]
