[Rob042]

Hi All from rainy Hampshire

while looking for a wheel to drive my diy turntable - am thinking of going idler drive/direct - I cam across this

http://www.vinylengine.com/diy_strobe.shtml

I have not checked the vinyl engine yet but is there some one out there that could make up the pcb's.
also could we look at making a group parts buy etc?

Hi Rob,

Have a look at this thread on WAD.

I built one and although not a quartz locked device, it's very good and cheap and easy. I know Neal has gone off his, but the secret is to have it calabrated wich James did for me. Mine remains bang on acurate and a very useful tool. All parts available from Maplins.

Best wishes,

Greg

Mine is calibrated as well Greg It drifts over time and temperature, the mains is more accurate!

[Rob042]

Thats perfect
cheers - didnt think of looking on the old site.

hows the best way to calibrate it - scope isnt too good and I dont have a freq counter/meter.
thanks again

Dropped straight in to my old version case, its accurate and does not drift. The duty cycle is shorter and it gives a crisper view of the stobe marks. Not bad for £5.

One of my old (bicycle) cycle computers has an R.P.M. counter function. If I put it on my Rega3, 45 is nearer 46. But 33 is 33.333. Dont know how accurate it is, but I think it cost about £4.99! If the speed is wrong there is not much I can do about it any way.

Yes, mine has arrived as well although not fitted yet. A very good deal.

this is gona help the diy deck i'm putting together - all I need is a reply on the motor.
