TV commercial, Servo Timer II

Two weeks ago we were contacted by an advertising agency filming a TV commercial here in Sydney. They required some water rockets and a launcher for some of their scenes, and so we helped them decide on the design and ended up making the rockets for them as well. Dad and I got to come out on the day of the shoot to help set up and launch the rockets. It was a fun and very interesting day.

Here are some behind-the-scenes photos:

We have also started making another batch of the Servo Timer IIs as we have had quite a few requests for these over the last several months. The servo timers are now available for purchase from here:

They are a little cheaper than the last batch as we were able to get better volume discounts on the components.

Using Scuba Tanks

This week we have put together an article on how to use scuba tanks to make an air supply for your water rockets. Although scuba tanks won't be suitable for everyone, the article tries to go into some detail about what components you can use and how you can connect them together. There are also a number of tips and things to look out for when assembling your own air supply.

Since we are often asked about how many launches you can get from a scuba tank, we have also included a calculator that will work it out for you.
