Wraith, the El Cheapo spinner

[mrsam]

Hi all,

As many of you probably already know I've been planning this for a couple of months and have now decided to stop procrastinating, pull my finger out and get it started.

Wraith is basically going to be a pretty low tech, old school brushed spinner that I can use for Whiteboards and demo's. The idea is to show people that you can still build an effective spinner on a budget, whilst it won't be all that damaging it should throw things around quite nicely.

So without further boring you with words, here's a picture of the main spinner set up, at least the pile of bits that will become the spinner set up, (Haribo's not a robot part).


That's a Johnson 850 motor on a 2.5 : 1 reduction via angle grinder gears wired to a relay and microswitch (still waiting on a servo), a 25mm shaft with needle rollers and a t5 timing pulley (64 tooth I think), a 2kg, 6mm thick steel disc and 2 blocks of 20mm hdpe (250 x 250mm).

Building shall commence soon so look forward to many updates.
