👾 HDMI Video Throwie Workshop

In this workshop you’ll use a Pi Pico microcontroller to send low-res (320×240) digital video to an HDMI display. Despite its limitations, the cool thing about this device is that it’s inexpensive enough that you can plug it in somewhere (perhaps a wall of TVs at an electronics store) and leave it behind for prank/art/propaganda purposes. The term “throwie” usually refers to a battery-powered device such as an LED light or radio transmitter with magnets on the back, tossed onto a high metal surface where it can’t easily be reached.

Your Pi Pico will generate video in the DVI-D format rather than the newer HDMI standard. But because HDMI is backwards compatible with DVI-D, your device should work with any HDMI monitor or TV.

Here’s what’s in the kit:

• Pi Pico board w/ microUSB port
• Pico DVI video sock
• insulated wire (4″)
• heat shrink tubing (3″)

Here’s what else you’ll need:

• HDMI cable
• microUSB cable with data connection
• computer (macOS/Linux/Windows)
• soldering iron
• lead-free solder
• flux paste
• header pins (optional)
• wire stripping tool (optional)
