I have a rather nice Desoutter electric screwdriver, in my ever-growing collection of 'projects'.

It is identified as:

S4 X2A 1000

Patent Number 2096510

The patent gives a good idea of how it works in principle.

Unfortunately [and almost inevitably] I do not have the Power Supply.

Does anyone have information on these items, please

... or any suggestions for a DIY version?

Depends if you have a use for the rest of this e-bay listing

Thanks for the thought, Jason

... but that would be a different script [which might not have a happy domestic ending]

For reference ... here's an ebay listing for an ESP-5, with an S4


[for reasons already stated I'm not planning to buy that one either]

Check out eBay listing 191106082551 it may be suitable.

Thanks, Roger ... Sadly; Although 36v, that's just a simple DC supply

As you will see from the ebay listing that I linked, the Desoutter connector has a lot of pins ... and I believe all or most of them are connected. ... Their box is full of cleverness!!



P.S. ... This one is a possibility ... but I was hoping to build something [cheap]

You'll need a circuit diagram and components list to have any chance of replicating the manufacturer’s PSU. Sourcing the parts would also be a problem.

Try looking for a local Desoutter agent, used to use these on production machines in the past and the U.K supplier was always helpful.

What type of plug has the drill got and can you send a picture. Its not difficult to make a DC power supply suitable for your power tool, that's if it is DC,the voltage regulation is not critical. If it is DC, then you will need a transformer, rectifier, a capacitor and a metal box to mount the bits in. I don't know any thing about Desoutter, but some of the body building power tool work on 400 Hz AC supply they are induction motors, not much bigger than air operated type power tools. John

The plug is a round multi-pin ... it fits the connector shown on the ebay item I posted earlier.

Sorry folks: I think I might be wasting everyone's time ...

There is a block diagram of the control electronics on the patent drawing [linked in my opening post] but no details.

... I was hoping that someone had a circuit diagram, or a photo, that would help me decide if an Arduino-based controller was feasible. With hindsight, it may be best to wait for a bargain ESP-5 box to turn-up somehere.



Edit: This video is the most informative I have found so far.
