Hey Guys, Could we use such a technique for other kind of effects ???

Sure, you could use this idea for any LFO (tremolo, phaser/vibe, chorus, flanger, younameit).
But any LFO based on a TL062 will be smaller and draw less current.

ahha, that's cool.
maybe in a flanger would give some interesting sounds...
Good god that's a lot of effort for a crappy implementation. Hacksawing pots? Filing the shafts to make the knob fit properly?
WTF. Just carry usable parts, Radio Shack!
Didn't watch the video, only had a random FFW to 0:40 and thought that said it all, so I missed the Radio Shack angle...

huahuah! These guys are always sawing the pots...don't know why they don't get the short ones...ahahah.
ITs crap I know, just found different from what I've seen...
Sometimes the pots you want are just not available in short shaft.
I've had that problem with some of the higher end Alps pots in the past. Hacksaw to the rescue.
On some of my 1590a builds, I put side knobs, but I mount them closer to the side, which requires me to file down the pot shaft (and drill out some of the knob. It never stops not being fun.
I remember hacksawing the shaft of a reverse logarithic dual alpha pot as it was ~5mm higher than the regular ones.

And you can use an ATTiny84 and get more control over the patterns and still draw about the same amount of current as an op-amp based LFO.
The spinny disk version is still cool though.
Lovetone used LED/LDR's in damn near everything. LDR's have a lot going for them -- low noise, plus the history effect smooths out any sharpness in the waveform a bit (or a lot, depending on what you use.)
That said, the sheer mechanicalness of the OP's link would make me worry. Can you imagine taking that out anywhere?
After watching that video I couldn't help but wonder how much it would cost to build that tremolo using all radio shack parts and supplies! :P
They mixed up how an ldr works...

Yeah, I can't help but also wonder how much light pollution is affecting the LDR.
Maybe it goes bit from the topic but I have to share it with you guys :)
This is mine try on phase 90 with few mods and optical speed control that I build for fun
Hope you like it :D

;D Wow, that was a great demo and a great sounding phaser with cool mods. I think you should start a new post with pics and build details on your mods mate, i bet that there are alot of people that hang around here, who would love to know, all the best, Matt
Thanks Matt, I will start new topic soon as I take some pics of the pedal. Currently all of my gear is in the studio so I hope that I will manage to upload pics and details until end of week.
