The optocoupler is a nice touch, build-in some robustness.
Do you recommend any specific motor controllers?

Maybe we should start a new thread for the Z-meter?
[QUOTE=-Elepro-;114325]it already was in my mind.... would you like a graphic display with frequency graph? ....... /QUOTE]
I figured as much.
I would like a red led and a green led, red means bad, green means good or maybe the other way around. I have no idea what I'd be doing with this device, only that others consider it important to have and I don't want to be the last kid on the block to have one.
If I could print out little frequency graphs to sell with each pickup, I'm sure I could get more money from customers (who are too embarrassed to ask what it all means.) If they do ask I can always refer them to the Q-tuner website...
I guess it would be nice to get a lot of "waterfall" data via a frequency sweep for testing new pickups designs but it would also be useful to get quick and simple "pass/fail" measurements to pickups I'm making by the dozens...

i like l297 - l6203 board based..... this could be a simple diy solution....Last edited by -Elepro-; 08-01-2009, 09:17 AM........my gaussmeter project..... ........

the winder firmware is completed
Redhouse, i'll send you the PICs for your test in this week....

we have to decide if we want test a complete DIY solution (with DIY motor drivers too) or with commercial drivers...........my gaussmeter project..... ........

Originally posted by RedHouse View PostGood point, which is least expensive?
- high output tension allow high rpm (stepper motor hardly cross the 600-700 rpm limit... for this my firmware mange 1/1 2/1 4/1 gear motor ratios) .... so i suggest a driver that can provide at least 30v
watch the driver in my previous render, it is a simple solution and its schematic is suggested in l6203 datasheet (i use it for many years but with different pcb...now i made new pcb for this application) it provide 4A at 45volt....
watch this links for IC costs
5X l6203 ....we need 4 ic for two drivers (but have a spare part it isn't a bad thing)
l297 we need 2
try to find better price....
watch schematic for other componentsLast edited by -Elepro-; 08-17-2009, 10:06 AM........my gaussmeter project..... ........

I believe I'll be able to make the PCB for the test unit so I won't need to order that.
What motors are right for this? in browsing 'round for Stepper motors I see quite a few different offerings, frame types, they seem to follow an industry standard, what motor did you use Elepro?.Last edited by RedHouse; 08-17-2009, 02:44 PM.

here's complete driver project... (we need 2)
i don't know how you make photo etching then check pcb image for the right side....
resistor from R8 to R15 are 2watt
capacitor from c1 to c3 are .2" pitch and c4 to c13 are .3" pitch
about motor:
at this moment i use two surplus 2ampere/phase nema23 bipolar stepper....
but i perhaps will change the main for have more torque so i'll can mount a 2/1 pulley transmission and have 2X speed..... now i have 600rpm
good motors for us have 2volt (yes 2 volt but we supply 30 or more.... inductance mistery ) and 1ohm/phase.... try to find 2 motors with this specification (or similar) at good price and then link me ...
about supply we can use a surplus pc at or atx power supply for +5 and +12
(and if you like a pc case for whole winder)
and transformer-bridge-smothcapacitor for motor supply (motors don't need stabilized voltage).....Attached Files.......my gaussmeter project..... ........
