Cheap string pot

[tmcnam]

Cheap string pot I built using retractable badge reel. The pics are self explanatory and there are links to my youtube videos that show how it works.

This may be too simplistic or something everyone else has already done but I just figured it out so thought others might be able to use it.

Edit: BTW, I used hot melt glue to attach the spacer block and the retractable reel. Fast and effective...

Hey Tim,
Really clever.
Now your cockpit will be also protected against a broad spectrum of bugs

Hi Roberto,

You can tell how long I've had some of this junk...no one gives away Zosyn stuff anymore!

I'm working on a simple design where I can cast the "holder" and the pulley out of a casting resin and use whatever reel and pot I want. Should make it a lot easier and only cost a few dollars.

String pots really are the simplest way to hook up most things...
Best Regards,
Tim

Hi Tim,
Great job, two thumbs up!!!!
I'm interested in 6 "holders" and  "pulley" made out of casting resin too. Please let me know if you can make few extra ones  I can pay you via Paypal. No rush
Cheers
Phil

I like it.  I used a key chain type for mine (type that have a set of keys on a chain that clips to your belt).  Works but I need some better pots.  That will be re-work # 2 someday.
