The 2017 Space and Science Festival Rocket
This design uses a special type of circuit called a joule thief, which is able to squeeze every drop of energy out of a AAA battery
– even if it has already died in your TV remote or computer mouse!
It uses an inductor (the big coil of copper wire) to store electrical energy, charging it up with current from the battery and then discharging it to drive the LEDs.
You can watch a simulation of the circuit operating and see how it works here.
These kits can be purchased from our online store, and all of the components in this kit are lead free and RoHS (restriction of hazardous substances) compliant
– safer for you and better for the environment.
The rocket design is also open source, so you can download the files and see how to make one yourself.

If you don’t have a soldering iron at home you can attend the soldering workshop at the @Day Festival on the 13th, or one of the 1st Assembly soldering workshops
If you can’t make any of these, 1st Assembly run soldering workshops on a regular basis, check their website here http://1-a.co.nz/
We’re grateful for the financial support of our sponsors to make these kits cost-effective, and for 1st Assembly for running workshops to help with the construction.
Need more? If you have a 3D printer (or can find one to use) you can make yourself a Rocket LaunchPad Stand designed by fre3formD http://1-a.co.nz/2016/05/25/gordon-dykes-fre3formd/
The 3D Printer file is available here http://www.thingiverse.com/thing:2308700
