We'll be closed on Thursday, November 27th. But we'll be here on Friday!

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 $8.50 to complete […]

Join us for a workshop on one-time pad encryption! We'll walk you through a technique for sending truly private messages without a computer, using 6-sided dice to generate random numbers. We'll use an encoder/decoder sheet that fits on a single sheet of paper and can be recreated from memory. You can find the workshop materials […]

At this workshop you'll learn to create passphrase-protected files using OpenSSL, a command-line program that's probably already installed on your computer. With this technique you can send encrypted files via email/Dropbox, then share the passphrase with the recipient on a secure channel (e.g., Signal). Useful for avoiding surveillance & data mining!

In this workshop you'll learn the basics of soldering by building a tiny oscillator circuit with two transistors and two LED lights. No previous experience needed! Register:  

Drop in any time from 10:30 a.m. to 1:30 p.m. and learn to draw cool geometric pictures using Python! It's just like Logo, the turtle drawing program that introduced a generation of kids to computers in the '80s and '90s. ☀️ Draw with code! An intro to turtle graphics using Python ☀️ Screen reading PDF […]

In this workshop you'll build a gadget that turns power on and off for a USB-powered device. Useful for rebooting solar-powered radios, making decorations blink, etc. No experience with soldering or programming required! You'll need to buy a kit for $11.50 to complete this project. Here's what it contains: - Pi Pico board with USB-C […]
