--- Quote from: srm_92000 on August 09, 2013, 02:25:28 PM ---Hi, When I started reading this thread I was doing a job on my little X0 mill that needed a lot of slots cutting in it, I also plan to make quite a few of these and was thinking how great just some basic power feed would be.. :proj: So when I read this thread a big light went on. I could use a wiper motor !!!!!. So not half an hour later a few ebay purchases were secured. Yesterday these turned up. The motor cost £6 inc postage as it didn't park the wipers any-more - no problem for me. It's from a Corsa C, comes apart easy, is well built mechanically and shows hardly any signs of wear. The controller is the £8 one from etang. It has well specified parts and works great with the motor on both the low and high speed connections. I've included a schematic I drew for those interested, it includes all the protection required with no extra parts needed. Base frequency measured on my scope is about 16.5 Khz. I hope the manufacturer/seller doesn't mind me putting this in but there is no way I could build this for £8 anyhow so I can't see it can harm. (untested circuit - build at your own risk values etc may be wrong.) --- End quote --- That "A2" diode is the freewheel diode :thumbup: |

Very pleased this thread has become useful for more than just building a fun arcade game. My controller also arrived today and I managed to pick up an old atx supply for £5 from a PC repair place. Spent two hours hooking up my atx supply with no luck and pulling my hair out, only to realise the fuse had blown in the kettle lead I was given! :doh: Anyway- perfect, nice and quiet and runs lovely. I've also painted the deck and screwed down some Florescent red Perspex which my daughter likes the look of. Lots more to do but progress is being made! |

Chris That's interesting. Do you have it working from +5V to +12V for the 7V or from the 12V direct ?? Don't bother about the fuse. It happens ... Couple of months ago I was about to rip my shop vaccy to bits, until I found out the switch on one side if a double 13A socket had packed up ... :bang: Ah well ... Dave |

Interesting project are you going to put a fiver in there as a incentive for the kids to spend all their pocket money in it? |
