Me as well, i love all these motors/engines that you bring back to life, just wish i could do the same/or even make one that works..Thanks for all your good work.

David

I'm always interested to read your posts - I'm sure there are lots of other lurkers too.

Not so fast!

I love engines David -- just hadn't seen that one, because I often don't watch YouTube links -- they're blocked for me (I just see a black square in the post), unless I specifically enable them for some reason. Sorry to others also, who only post videos, and not pix -- I rarely read those threads, unless what your video is about is explained and there are photos in the post -- just me..... I'm a reader more than a viewer.

Anyhoo, love the little engine David, and the LTD, well what can I say, but obviously I like that one, since I've owned the same one for several years! Here's mine:



BTW when I first got it I did an experiment with it, I made a new displacer from white ScotchGuard and it worked quite well with a porous displacer -- as a regenerator.

Anyway, the more engines the merrier as far as I'm concerned!

A little late to the party. Nice to see it running Dave!

BUT that LTD!

Thanks, Eric.

The LTD? I'm a bit disappointed, no-one thinks it is worth a comment.......  :scratch:

I guess, everyone has moved on. There's little interest in engines, on here anymore.......  :(

Suspense is killing us! What did he do to fix it? You can't leave us hanging...

Chuck. This is his explanation, on our steamtoys forum......

David ( Stilldrillin ) did so much work on a little flame gulper engine of mine and sadly he had to send it back last year as it just wouldn't run .

I just wouldn't give up on this little beauty so every now and again I would get the engine out and maybe have a fiddly with it or adjust something then I got to looking at the meths burner  so I tried different wicks and adjusted the length of the wick then it sort of run SO back in the cupboard it went then perhaps a week or so later I would get this little FG engine out and I noticed the slide which covers the cylinder hole was knocking the wick so I then altered the height of the burner and found if
I altered how close or far away from the cylinder it was then the engine WOULD run but at different speeds.

Well some have asked how small  " Little Munchkin " is  ..

I am not sure whether I understood Your spesification correctly.

So You want to get a defined amount of pulses triggered by some input.

Nowdays one would harness a small microcontroller to do that sort of a task. It probably would take less space than a dedicated IC circuitry.

So.

Using AD converter to adjust the number of pulses. Another AD as the frequency setup. One input pin as the trigger and another as the output. PIC18F25would be my choise for this kind of a task.

This MCU can be clocked to 64MhZ by it's internal RC oscillator and one can put it into sleep while not doing anything. (Wake up by INT0).

Instead of scripting You would find Yourself doing some MCU code ... and as You are an Oldtimer - probably with assembler :)

Hi
Took your comment on board Martin and mounted DTI to measure vertical on a sliding block so much simpler  :doh:
