Motion Machine

[Sean Goddard]

Hi All, I have designed a motion machine with a VERY high power output oscillator, but have no time to finish the design.

The schematic is the PDF above.

Can someone with a little more time than me build this and let me know how it performs. MIGHT need a few mods here and there to get the stability up to scratch.

BTW, uses STANDARD Tesoro search heads.

Visit my website and email me if you have any luck with this.

OH, if you get a decent PCB designed, can you let me have the layout as well please?

Re: Motion Machine

Hi Sean

your design looks pretty professional! Can you post the Protel DXP schematic file in the forum too? This would save a lot of time if someone is interested to make a PCB.

Re: Motion Machine

Hi Sean,

Looks good. Is the top of the GEB Control supposed to go to VCC?

Re: Motion Machine

Hi all.

Firstly, Nope, the top of the GEB control doesn't go anywhere but into fresh air ;-)

Secondly, I'll TRY to post the .SCH file below. sorry if it doesn't work. BTW I've nearly finished a PCB myself, but I'm open to anyone else who can make a better one (shouldn't be hard. I'm rubbish at designing PCB's ;-P ).

The file is in Protel DXP format. WILL NOT WORK in 99SE (unless you know otherwise).

Re: Motion Machine

dear Sean,
thanks for share of it.
it's a project of mine (only disc part) as an example.

Re: Motion Machine

Hi kt315

Your layout looks okay. One practical tip....if you design next time a new PCB you shouldn't forget to place mounting holes (usually in the corner). PCB's are usually mounted somewhere....

If I do a design I place first mounting holes & connectors, "critical" components like potis with 6mm axis etc. This parts have a "fix" location on the PCB and need to fit later into a case for example. After that I place the remaining components.

Re: Motion Machine

I use "Blu-Tac" if it's a prototype, but for a production model.

Have to admit, I HAVE made that mistake, and missed the mounting holes off once or twice (rolls eyes).

Let me know what you people find with this design (bugs etc) thanks!

Re: Motion Machine

hello Chris,
thanks for the note. it's only test version of the project, so the things are not so critical now for me. all pcb now is that link.

thanks again,
all the best

Re: Motion Machine

Hi kt315,

Is this the PCB for the circuit I posted above please?

If so, do you have a component overlay, have you tried the circuit yet, and is it OK?

Email me if you want to take part in the testing / development of this circuit or if you have any suggestions etc.

Re: Motion Machine

Is that realy whats considered a high power oscillator, how much current could flow through the coil and the emitter colector junction with a 1.5k in series. My idea of high power would be more like an oscillator driving a pmos fet with a very low source to drain resistance or a bridge circuit with four times the output. What is your view on this, what is realy optimum and worth the battery drain trade off.

Hi Sean,

This threads gone a bit quiet. How did your design perform?

This thread is dead because the PDF file is no longer there that shows the circuit diagram. New readers can't see it or have a clue what the circuit looks like. Did it work very good?
