As part of an order from Better Equipped, I sent for a ping pong ball shooter. This consists of two rotating disks, which propel a ping pong ball forward.
So far, I have only partly built this. I need to do some soldering to complete. I also want to find a safe place to test it. This project will be demonstrated at the Paignton Library STEM group, but could be used in a school too. This would support, Science, Maths, Design & Technology and possibly other subjects.
A timeline for the programme is available with student applications starting in March. This should give time for people to research any projects they want to help, learn additional software for example before starting.
I have been building some small electronics projects based on the 74HC/LS series of Integrated circuits. In essence these are small boards with a 14 pin IC holder soldered on, along with header pins of different colours for +V, GND, Input and outputs.
so far I have built two based on the 74HC00 Quad 2 input NAND gate and one based on the 74HC08 Quad 2 input AND gate. So far they work really well. I am hoping that these can be both powered by and used via a Raspberry Pi or Arduino. The intention is to build some boards up for use in teaching about digital logic.
