URL? to the thread please... I cannae be arsed to search for it, or even open my eyes... just give me something to click on that will take me to the thread :rofl:
okay, to continue the story: I checked out some motorized pots, but none of them could do more than 3.5watt, except one that could do 5 watt but that's still not what I was expecting, as it's a 10 turn one, and I don't want to turn it so much So, if anyone knows of a motorized potentiometer that does 5 watt or above, pleaaaaassseeee post it here! ...the quest continues ...
My dad's sterio has one of those! It is so cool, seeong the knob move by itself! Every time someone sits on the remote, their guests freak out, because it moves without help relix, yet another good idea!! Keep 'em commin!
/me slaps relix for ressurecting this old topic Linear was refering to you using the pot to control the voltage of something, but you'd need a voltage regulator so that you don't blow up your expencive motorised pots You could use it to control a PWM circut, like the one macro used here. Too easy!
Yes we get shafted on price but anyone who buys from RS is hanging a big sign on their back saying "shaft me please" We do get our LEDs cheaper often?
Hi all. If you give me the equmiment , then i'll build 1 thingy for you (for free):dude: . I will make a PCB and post the progress on your site (i'm already have a schematic in my head.) /
Yo_Duh is working on the same idea right now, and I'm trying to participate in making it a reality. That motorized pot would help very much. Linear: I haven't seen one but do motorized rotary encoders exist too?
Why don't you use a simple microcontroller such as a BSX-II available from www.parallaxinc.com and 4 sub minature servos, then all you do is drill a hole in the spindle and run a rod through it so you have a T bar (so to speak) then connect stiff wire to the servo, the servo can be controlled to an exact position from the microcontroller and it can take inputs from heat temps etc. It can be automatic or with a press of a button can become manual. You can even set presets with a microcontroler! So if you find a setting that works paticulary well you can save it in the controllers EPROM then call it later.... watch them knobs set themselves!!! ooohh!!! The controller can be easily programmed to control an LCD so you could wire it up to your existing LCD to create menu systems! If you really wanted to be flash you could program the controller to flash the LED's as the knob is turned. Give it the "professional look!" I've given myself ideas now.... cheers guys!! I'm going to have to dish out even more money for stuff now!! I'll keep you posted!!
well, apart from the drill hole in servo thingy, I was thinking just the same (got the idea from the turning volume knob with blinking led on the stereo of my brother). Clever idea there with the servo's, but I'm not that good in electronics so I should go for the most simplistic method. Read my Ultimate Baybus thread for the other ideas and stuff
