With the software all written and tested, it was time to package the electronics into Buzz’s spaceship. That involved unsoldering all the wires then connecting everything up again using measured lengths of fine wire. Here’s the tiny flight computer:
I fitted the components into the spaceship top, except for the batteries (in the base to keep the weight low) and the radio transmitter (in the base, close to the antenna).
Here’s everything wired up. Some of the wiring is loose still but will be tidied up when I figure out how to connect the top and base!
Here’s the base, before the antenna was added. The foil acts as a “ground plane” for the antenna, directing the signal towards Earth and increasing the range substantially.
Finally, some shots of the (nearly) completed spaceship, being tested in the garden.
