My Self Bondage Chair Project

I thought I’d show everyone my self bondage chair project. It’s still in the later stages of development but I’ve “road-tested” it a couple of times with excellent results. The pictures were taken in my "workshop" on an industrial estate on the outskirts of Newcastle.

 

The basic frame is built from wood, which has been planed and sanded then painted with water based black satin paint. The bondage is provided by four electromagnets, powered by a 6v power supply. The leather cuffs attached to the magnets came from www.spankinggood.co.uk (who I can’t recommend highly enough).

The electro-dildo (seen here covered in tape and plastic for protection) is attached to a 50mm stroke pneumatic cylinder, which in turn is controlled by a solenoid. The air system pressure and the exhaust port of the solenoid have been adjusted to provide a safe amount of pressure to the dildo.

Punishment during a session is provided by an ET-232 unit connected to electrodes on my cock and balls and the electro-dildo. The electrodes/dildo can be controlled by the system to provide short or long shocks at pre-determined intervals.

The whole system is controlled by a relay-sequencer unit connected to my laptop (via USB). I bought the sequencer from www.pc-control.co.uk You can write sequencer files using the included software to control the eight relays on the board. Each step in the program can be anything from 0.1 sec to 99mins. I’ve written about half a dozen files so far, with each session being 45mins long (but could be as long as you want). I put all the files into one folder on my laptop and then bulk-rename them so I don’t know which file I’m choosing each time I start a session. As I write more session files this selection becomes more random.

For safety the whole system is attached to a 60 minute timer so if anything goes wrong the electrics will cut out and release the electromagnets. I’ve installed a safety push button emergency stop which will release the electromagnets if pushed, BUT to ensure I don’t use it during a session unless I really need to I’ve also attached a sting in the tail. If I press the emergency stop I will receive a high voltage electric shock to my cock and balls, the shock is painful but still very safe.  The shock is provided by an electric kit from www.kenneke.com

To finish off a session I have a vibrating electric motor attached to the end of my cock, which is controlled by the sequencer. I’ve found this to be the most effective way of  providing relief while bound.

During the sessions on the chair I wear tights, 5 inch heels, a catsuit, corselette and a heavy duty gas mask. To remove any noise I also wear a pair of ear defenders and headphones (attached to my mp3 player playing white noise).

Since taking the pictures I've added some head restraints which attach to my gas mask and I’m going to add some more restraints, probably belt and buckle type, to increase the bondage. I have some spare electromagnets (about 10) which I may sell or add to my chair I haven’t decided yet.

I'm allways looking for more ideas for additions to the chair if anyone has any ideas?

Thanks Steph, nice to know that my handiwork is appreciated. I'll try to keep this post updated with further developments.

i would be really interested in seeing more pictures.  maybe with the "victim" in the chair! 

Do you find the electromagnets strong enough to hold your arms and legs?  

Me too.

That is absolutely amazing.  Nice work!

brilliant feat of kinky engineering..i'm an engineer myself so i can appreciate the work and creativity that went into this....excellent job!!

Thought I'd add a few more pics, these are from Friday 8th Jan. The pictures show the chair being setup for a session.

Here you can see a few more details of the wires, also my 5 inch heels


This pic shows the wrist cuffs, dildo (plus Lube), gas mask and the vibrating cock motor (resting on the gloves).

I've bought some pressure sensor sitches which I intend to place beneath my bum cheeks, so if I move I will get a large shock. But this is for a future session.

I'm still looking for more ideas for additions to the chair so if anyone has any please let me know.
 

You stated

OK

More straps, again magnetic secured, at upper arms, forearms below elbows, across torso at chest and waist, (these two and following could be manual buckled), at legs at thighs/crotch, above knees and below knees, and a magnetically or buckled collar.... make it a true bondge chair.

 

Also, taking an idea from Charlotte Fetish.... i  have observed that if her rigid  hogtie trainer was constructed out of pipe, and had a metal dildo it could be tapped for water input/output and hot or cold water used, as well as electrostim connections, why not such a dildo with such connections for the chair??

Sadism not my thing, just the ride

Great work!

Being a sucker for nipple clamps, I'd figure out a way to have those computer controlled as well.  Maybe another stroke pneumatic cylinder, but initially just a magnet to hold them taught or a magnet to hold a weight (magnet off drops the weight and then you really feel the clamps).

No, but I will explain further.....The pc-control board I'm using is basically a sequencer, it follows a pre-set sequence of steps that I have previously entered. This could be called a program but it is not in the sense that I am writing in a language, I am just entering steps into a software program. The sequencer software allows you to switch 7 relays on or off at intervals from 0.1sec to 99mins, you can enter an unlimited number of steps, allowing you to control the relays as much as you like. I can save these sequences and recall them so as to randomise the choice I'm making.

I hope that clarifies the situation.

It does, but it tells me you'll probably have to team up with someone with similar hardware to get you up to speed on Visual Basic or C++ programming:

There's another company that makes similar stuff that has lots of programming support - you might be able to get some ideas from their site:

wow this chair is most amazing i have seen yet
could you have an urethra attachment so say 30 mins into session urethra trode goes from being just inside your cock to anoth 1 inch down or something similar
