This thread got so technical all of a sudden.

But I do love the mental image of a good paddle-catapult smacking from down below.

Hello! Trouble is I'm in the UK. Any Doms need a sub engineer? :D

Ok, I have thought about this a lot. I have also built a working dual spanker that used two fairly expensive motors to directly swish a couple of leather belts. The motors came from an old computer tape drive (from the 1960's) and are high quality, driving them with a pulse of 30volts for a few 10's of ms powered them for about 1/2 a turn and was sufficient to deliver a nice little spank. Several dozen of these went down well!!!
I programmed a microprocessor to deliver random strokes as well as lock / unlock me. More on this once I resurrect it!

Now to my point eventually sorry, it isn't simple to achieve the "thwack,.... thwack...... thwack...." one really is after, certainly not using a ceiling fan. The motor just isn't powerful enough as is.
One "cheap" way may be to use a cordless drill as its motor is geared, thus increasing the torque. Again, one could use a cunning timer / microprocessor to switch the power from the battery to the drill while taping the trigger on full. I may be straightforward for a competent DIYer to arrange a whip or belt (strap) onto the chuck and hey presto a spanking machine. However I have yet to test and prove all this. In my opinion there should be no good reason why this will not work.

But again, sorry, it is most unlikely to be simple to achieve a good spanker without plenty of DIY and some electronics / computer skills.
There again, that is one of the things that excites me, to use my knowledge and hobby to make exciting self bondage scenarios!

Agreed there is simply no such thing as a "simple" spanker. The only realistic methods are either very expensive high speed/high torque motors (along with very careful control! you really don't want a spanker using them going wrong) or storing energy in a spring/bungy using a relatively cheap low speed high torque motor, control is still important but because of the gearing/speed involved you have a decent chance of using your backup release before it gets really nasty.

Servos/steppers with the speed/torque required are VERY expensive and then there's the specialist control required. The Pain4fem machine uses a bog standard geared motor and a sprag clutch, relatively simple and cheap but you still need a reasonable level of engineering ability.

To use the motor to do the spanking is the hard/hi-tech way to do this...
In this case, the low tech is the way to go...
Spring to do the swat, and a small motor to pull the paddle back...
Anything else would work better as a constant whipping action...
... unless that is what you are after...

And potentially very dangerous, if you are feeding a High torque High speed motor (as in the example above) with 30V for several 10's of ms what happens if the control circuit fails and powers the motor continuously, things could get very nasty very quickly. Of course the control for a low speed geared motor could also fail but at least you have some time between whacks to realise what's happened and use your backup release. The safety of a "direct drive" system could be improved by charging a large capacitor with just enough energy to power the motor for one "whack" with a changeover relay to switch between charging the capacitor and dumping the cap's energy into the motor, by current limiting the supply it would be able to charge the cap fine but if the supply somehow became attached directly to the motor (unlikely with the relay in circuit) then it would not be able to drive the motor with enough power to cause damage. But then if you're going to do that it's worth investigating "over-driving" rotary solenoids as used in this drum kit :-

The solenoids are driven by 100v pulses from capacitors, you need to keep the duty cycle fairly low or the solenoids will burn out.

I'm not sure if this would actually make it easier to make an effective spanking machine, but it may be possible to get good results if the "automatic" feature is loosened. It wouldn't be difficult to make a device that delivers one spank using a simple spring with a release. An addition to this that somehow forces the poor sub at it's mercy to reset it manually would have the same effect. They could pull the spring tension back by pulling a rope that they can reach while bound.

This does leave the "motivation" to reset it unsolved l, but it at least solves the most technical, motorized problems

I like the manual reset idea. It forces the sub to be responsible for the action/pain. If a counter was added that was tied to the release mechanism, the sub would have to administer the proper number of hits before the keys become available, or some other release method deploys. There would be no real time limit, and the sub would have to decide whether to get out quickly, with a rapid series of painful hits, or whether to drag it out with more time between hits.
Perhaps a ratchet mechanism that lowers the keys a small amount each time the spanker is reset could be devised. Properly designed, this could have the effect of forcing a complete stroke reset to ensure a strong hit.
A lot of possibilities here.

I have an idea for a simple whipping machine. Purchase an inexpensive electric fan. Remove the cage around the blades as well as the blades thmeselves. Attached 12-inch strips of leather or plastic to the locations that previously held the fan blades in place. Be sure to space the strips equally so the fan is balanced when powered on. Set the fan controls to "on" so the strips rotate when the fan is plugged in. Make sure everything is balanced well when operational.

Secure your slave near the fan so the leather or plastic strips whip his/her ass (or whatever) when the fan is plugged in and becomes operational. To turn it off, just unplug it, or let a timer do the work.You should be able to run the whipping strips horizontally or vertically depend on your mood or the area to be whipped. Enjoy watching the slave squirm as they are whipped. You might even be able to have the fan rotate so more than one area gets whipped. Have fun!

I built a simple spring powered spanker here:-
viewtopic.php?f=12&t=13142
It has almost unlimited power, depending on the spring(s) you use. It an also spank as gently as you want.
