Power ratio over one

@AHHHHHHH

Here is a diagram of how I see it work.  Please correct me if needed.

Here is a spec on the micro contact.
Rated 6A and 250 VAC (1500 WATTEROUNIES)
Electrical life at rated load - Minimum 6,000 iterations.
These contacts will last and last and last.
http://www.cherrycorp.com/english/switches/miniature/e51.htm

The four micro contacts each have a LONG THIN METAL LEVER (Mechanical). No magnet needed.

So one side of the battery goes to two micro contacts, the other side of the battery goes to the other two micro contacts. Just flip the wires so each side is the reverse. All contacts are NO. That is to say when the teeter is up, the two micro contacts are NO hence open.

The micro contacts levers on the down side of the teeter are pushed downwards, so if they are also wired NO, then these two are closed in one polarity. When this side rises, it will open, the other side will close in the other polarity.

@HG, when you get a device name, let us know and I'll change it on the diagram.

Thanks, that's all I can see too Wattsup.

Hay Stefan:
The driver coil (#15) is the electromagnet. All it is, is a single strand of 15 gauge wire, wrapped in a coil. If you have a coil of wire hanging around, put a permanent magnet inside it, touch a battery to the two coil ends, and the magnet will move. Wattsup schematic is exactly right. There are no magnets or electromagnet in the switch assembly! In the video you reference, I moved the teeterboard with my fingers to show the operation of the teeterboard in relation to the movement of the engaging lever (#4).
Wattsup's schematic shows all there is. Thanks Wattsup. It looks like you might be the first to replicate this device. If that?s so, I?ll let you give the device a name!

A transformer does not work well for the input. To much humming, and the secondary unit doesn't work right.

Hi David,

I do not think Stefan meant the transformer for the input in the sense you mentioned: I think he suggests you connect the primary side of a normal 120V/12V mains transformer to the output of your green coil and the secondary side of this transformer would feed a full wave rectifier + puffer capacitor, so the DC power gained this way would replace your 1.2V battery, you simply would remove the battery after hooking up the circuit...   To avoid a runaway situation, some ten Ohms of series resistor  (in 20-200 Ohm range) is advisable to insert to reduce deliberately the power coming from the puffer capacitor. If your device stops after hooking up and removing the battery, you can reduce the series resistor gradually or even short-circuit it and see whether your device continue running in this looped back connection. A bulb rated of a few watts would be better instead of the resistor though.

Because your output peak voltage is in the range of 40-60V, the output voltage at the secondary of the transformer will be around 4-6V peak, so after the diode bridge rectification the puffer capacitor will have an unloaded 6-9V DC output: of course when your driver coil is connected to this through the switches, the DC voltage will be significantly reduced in the capacitor and an average stored voltage will remain in it, once it has a chance to recharge from the transformer.

Such transformers are found in normal plugin power supplies, I think you call them wall transformers, you may find them at Walmart etc in the 12W-20W power range, usually these are AC/DC adapters, (NOT the switching types!),  maybe with only one diode + a puffer electrolytic capacitor on their secondary side. There may be variable output types where the secondary coil has several series windings and with a slide switch you can choose 3V,  6V,  9V and 12V DC output, such would be better for the looping... but in the lack of such adapter, with one output voltage value only,  the series resistor or rather a bulb mentioned above surely helps.

Here are links on the kind of adapters I think of: http://www.allelectronics.com/cgi-bin/item/DCTX-980/790/9_VDC_800_MA_WALL_TRANSFORMER_.html   or http://www.allelectronics.com/cgi-bin/item/DCTX-4175/790/7.5_VDC_TO_9_VDC_WALL_TRANSFORMER_.html
You may choose a mains transformer only like this:

Of course you may choose not to do such looping with your device... If you do, I can make a schematics on it for you to clear everything up.

Thanks,  Gyula

Hay Gyula:

Sure, I will try this suggestion. My point with Mr. Krieg is his unreasonable expectations, and name calling bully attitude!   If your schematics are drawn out like Wattsup?s, I shouldn?t have to many questions.  I haven?t done any tinkering in a long time, and am looking forward to having ?fun?!

Thanks for your assistance.

Hi Gyula,
yes, I exactly meant it like this.
With this addon David should be able already to selfrun his unit.
Many thanks for pointing it out in detail.

Regards, Stefan.

Hi David,
I edited the wiring diagram from Wattsup and here it is enclosed.

Where do we exactly find the coil #15 and the drivemagnet in your pictures
and your videos ?
Is it below the switch 12-B , so not visible in the pics and videos ?
