homemade ball slapping machine
Hi,
I want some ball pain but I can not do it myself so I make ball slapper What you need: Fan (i use CPU fan) wires something for slapping (I use wicks on bast) hard surface to attach fan power (batteries or usb cabel) ______________________ You have to cut fan of "cage" but leave protruding pieces so you can bind it there. Do hole in one fan paddle and bind there thing on slapping. Next take 12V wire from fan (in my case its yellow) take it on "+". GND (ground-black) should be on "-". Most PC fans are on 12V, but they need at least 4,5V, USB have 5V. In my case, there is 9V and fan is running on 500rpm (rotation per minute) so after half minute I have smashed balls and it is still hurts. I want to edit it. Add on/off switch maybe touch switch and get smaller accumulator. Images: |
