Behold the balls!
There is no point making a 4g payload then wrapping it in 100g of payload. I theory I could just throw it in a bubble wrap bag and have done with it however as this is its first launch I decided to encase the lot in a 10cm polystyrene ball.
Using a hot wire cutter I sliced the top off the ball. This would be the antenna section :
With a little coax, some single core wire, some drinking straws and hot glue an antenna was created. Next the payload section, another slice was made in the remaining call with the hot wire cutter :
Finally some hollows were made for the battery and tracker board :
Finally the remaining top bit will have a straw through it for attaching to balloon/parachute, I’ll paint it pink tonight and report back !
