You have a deal! I'll print up another 60 and drop them off to you next time I'm passing. Do you want the old chairs back as I recycle the parts?
What happened at your workbench today?

Carrying on from Post 2618, the following was now surplus after the conversion to DCC.
Thinking outside the box, spot of Recycling......well more of a Reclaim and Reuse project.
Push Button switches salvaged from the PCB, diodes left over from the voltage regulator upgrades for use with DCC, blue terminal blocks reclaimed from some dodgy crappy cheap Chinese PCBs that had failed, also fitted in the repaired Point Motors, odd piece of stripboard left over from a previous project, link wires to connect the various bits together, salvaged from a roll of 8 core Telephone cable found chucked in a skip.
And, even the transformer which was being chucked out for no apparent reason, other than it was no longer required.

Modified Servo Controller PCB, experimentation with various values of resistor.
Control via a Massoth 8FS Decoder, basic motor control, some further tweaking and adjustments to fine tune the control of attached motor.
Trial run with a N20 DC Motor, operated and controlled via a Massoth 8FS Decoder.
Trial run with a M130 DC Motor, operated and controlled via a Massoth 8FS Decoder.

As a low cost solution, and for their minute size, so far so good, not destroyed one yet!, fine tuning and tweaking does help enormously, just a case of finding the optimum value for the resistors.
Ordered 5 more 9g Servos to experiment with (5 for £10.00 not going to break the bank), ultimately once satisfied with the correct value for the resistors, will look for SMD versions, make for a neater and tidier installation.
Does look like a likely contender to replace the ESC already being field tested, would actually be able to fit the whole shebang inside the Crane, and only have one pair of wires to connect to the host DCC system.
Progress will be slow for a week or so, awaiting spares and components, looks like good weather for the rest of the week, guess just have to play with the trains outside in the sunshine.....
Below testing the Servo Controller board with a Servo tester.
Servo Controller board, connected to the Massoth 8FS Servo Decoder, operating the Playmobil Crane Transverse Motor, not quite there yet in terms of controllability and smoothness compared to the ESC, progress can be measured in small deliberate steps.

Nice. For things like cranes, you can also relocate the servo pot to another point on the model, so that you have direct proportional control. Useful for jib and panning movements particularly if paired with a different control pot, to extend control range.As a low cost solution, and for their minute size, so far so good, not destroyed one yet!, fine tuning and tweaking does help enormously, just a case of finding the optimum value for the resistors.

This morning I have been fitting replacement couplings to my two GE 25T Switchers and to a few wagons:-
The couplers are made by Porter House Models.

Having seen this, I've just ordered a pair to try, for a specific job, as I respect your wisdom, Paul. Naturally, I'll blame you entirely if it doesn't work!

Martyn, I am very impressed with them. I hooked 24 wagons behind the switcher, it was able to pull the entire consist all the way around the circuit without the magnetic coupling coming adrift:-Having seen this, I've just ordered a pair to try, for a specific job, as I respect your wisdom, Paul.

Nice, I am assuming the end section rotates slightly? These look very similar to some I designed for my stock. Indeed, I believe the files are on her for anyone with a 3D printer.

'Not much..' - Has happened, that is.
Some washing has been done.
Some boxes rearranged.. - The got out again, as I needed something.
And a contract garden (Student let, next door) was persuaded to trim a little of the overhanging tree, so that has been reduced in volume, and binned...
Washing hanging outside, so I can put the boxes back, and fire-up the soldering iron....
Oh! I cleared the dining table:

, PM is on its way....

No rotation, only side to side movement.
I can see a use for these, but for my line where uncoupling stock is a regular thing not of much use to me. Tried magnetic couplings that were marketed some years back that were in effect a magnet in a bit of tinplate with some wire. They were the same thing up-prised as sold by Maplin as battery connectors. As sold they were a good choice for batteries, of course a very different beast to what Paul has been testing out.

Sorted and putting to good use the stack of Playmobil spare parts, as below converted from a fixed base to moveable.
Disassembled one of the cheapo Servo's, delicate touch needed to unsolder and remove the motor from the PCB, new motor leads soldered on.
The leads from Potentiometer were snipped off, left with a small tags to solder the two resistors onto.
Quite different from an earlier version, top one the later version, steady hands and good vision needed!
Bottom one, the earlier version, much simpler to deal with, Motor and Potentiometer were both connected with flying leads.
Later version of the Servo PCB on test with a DC Motor.
Servo Switch dual output, operated directly from the Massoth 8FS Decoder, four options for the lights,
On/Off
Single Flash
Double Flash
Fade In/Out

I have fitted a couple of drivers(engineers) into the cabs of my GE 25T switchers:-

But these being circus locos, surely the drivers require top hats and tails
I like those magnetic couplings, but the maker appears not to ship to Canada

Chris, I have just looked at Porter House Models website and it would appear that they do ship orders overseas. The websites says contact for correct postage.But these being circus locos, surely the drivers require top hats and tails

Give it a try, the couplers are great.

I've just fitted them on the two units of my current railbus project and am itching to try them out. But only once I find out why I have red headlamps showing at both ends
Someone's got his wires crossed.
