...except Pocket Spacecraft is even smaller. One of their probes is a CD-sized mylar disk with a solar panel and an Arduino-compatible microcontroller printed on it. The antenna is a wire ring around the outside. Sensors are minimal (I believe one of their models has a single pixel camera) and of course there's no propulsion. They were planning on launching hundreds at a time via cubesats.
They did a Kickstarter last year --- £99 for a vehicle in Earth orbit, £199 for one in lunar orbit --- which failed, but apparently they got funding elsewhere. Their website's short on updates but their twitter feed is active.
