Making me see that is cruel and unusual punishment! You take that down right this minute!

I always wondered, what the purpose of those holes in American plugs were for. Now I know.

it seems not original hitachi have different layouts/equipment.
I have a 10 speed USB charged one.the motor with an offset weight is located inside the head assembly. I just can't find the damned silver ring holding screw)))))))) I've flexed the shaft in all directions-there's a flexible rubber/plastic cover.nothing else.it's very powerfull on ,but now doesn't work at all(worked weaker and weaker till it died completeley).maybe the battery is faulty?it worked with the USB cable attached too,without premature charging

I've heard there is a new diesel engine replacement for the lovers of the lower speeds....great torque.

The circuit is a pretty simple design, but they really cut corners with the motor. Sure it's big and powerful enough, but it's a cheap brushed DC motor instead of a quality AC induction motor. Since it's a DC motor, it uses a full wave bridge rectifier to convert the AC to choppy DC. The low speed is created by inserting another diode in series, effectively cutting the power in half. It's a common design.

I included a schematic as well.


I've tried opening the pic of the spring... do you happen to know the gauge, or a better gauge to replace to stock spring?

My Husband is an xray technician and so we have spray cans of a cleaning/lubricating agent that looks similar to wd-40 just laying around all the time. I have used it for everything from door hinges to squeaky electronics and even to kill a roach once. I knew it was safe to use on electronics but It never occurred to me to find out if it was what is BEST for them. I have no idea if it is a grease or an oil until just now I don't think I ever consciously separated the two in to subcategories of lubricant. I feel both enlightened and want to share said new found revelation with pinterest yet also embarrassingly daft for not thinking of it on my own. I guess in my head its like cooking french fries, you drop them in the oil you take them out and dump the grease the two are interchangeable. Weird. Thank you for the tip and pointing out the difference.

The three way switch doesn't work any longer. Anyone know if the switches go bad, or maybe some wiring is bad. If the switch is bad any idea where to get another switch. Thanks for the assistance in advance.

Thank you for posting this..

Looking to hack the Hitachi magic wand to get more out of it.

Did anyone ever replace the motor?

Any good sources on replacement motors.

Thanks again.

*BAM* The diodes exploded, tripping the breaker once again.

Then I realized another stupid mistake: the diodes were only rated to 20 volts. I replaced the diodes yet again, this time with a beefy 600 volt 20 amp bridge rectifier. I carefully plugged it in again.

*Whhhrrrrrr* Success! I got it working just like it was originally. Of course, this isn't what I set out to do...

I added the decoupling capacitor again, this time checking the polarity several times. It still worked, and the motor was noticeably faster. Then I added a pair of filtering capacitors to reduce electromagnetic noise. The only complaint I've had with this vibrator is it causes interference with my wireless mouse.

I put it all back together, and it still works. I haven't had a chance to test it properly, but I will in the near future.

I've included a new schematic. My modifications are in violet. The filtering capacitors are connected to the metal case of the motor via a mounting screw.

With this, my 500th post, I just became a Literotica Guru. How appropriate.

Is it weird that this description has made me squirm
