hi, i want to use some sensors to measure the distance accurately to use as a feedback to a wheeled mobile robot. the distance can varry from a range of 10...
OK here is the first circuit. CamHead 1 uses 3 chips and is based on a modified Bicore Head with 2 photodiodes. The "camera" uses 4 PDs with some kind of lens...

OK SpinCam is a total simplification of Beam Video but with little electronics to get in the way, the design demonstrates the scanning "video" principle very...
Ok, I scanned all the decent Turbot images I had, and put them into a gallery on http://gallery.solarbotics.net. You'll see where. Also, we're doing another...
Hello Alex, ... Great idea! First and foremost, a recap of the thread so that I can keep on topic. Wilf originally brought up the subject of BEAM aesthetics. I...

check out my newest robot, the brain is less than 1 cubic centimeter... he's a photovore.the circuit is 2 LDR's and 2 transistors.. he works pretty good, when...
I'll build this circuit right now!!! Just some questions: Can I use a usual rpm motor (35rpm)? What is a pinhole lense??? Is there something else I can use? ...
... Would'nt this be a problem for the ''refresh rate'' of the PhotoDiodes? I don't know how fast can a PhD change i'ts resistance, but I think you may have...
Adam, AAAAAHHHHH! It's so TINY! Did you make it using standard transistors and stuff? Do you have a freeform diagram or tutorial I could use to try making one...
No problem. Unlike Light dependent resistors, which are very slow, photodiodes have a response time spec of 20 nanoseconds. In this circuit the response time...
Keep the mass as low as possible. The head should rapidly shake back and forth like a bicore head at a rate of about 10Hz. The angle of shaking is no more than...

yea, standard stuff.. NPN's and LDR's from rat shack.. the motors i am using so far is just from tiny RC cars, but i have some ordered from BGmicro. i don't...

Hello Dave, Really appreciate you sharing your expert opinion on Turbot 2.0. ... That's thrilling to know. For one, they look like LEDs and I had reservations...

... I was tired when I wrote that. I mean that I think he was using the standard 1.2V drop across the LED for some sort of reference, much like you expect a...
Seems I caught Mr. Tilden "going mobile". Blackberry's must be a handy gizmo. Regards, Dave ... "Um, no - that's H,R,Y,N,K,I,W. No, not K,I,U,U, K,I,_W_. Yes,...

Thank you very much, Dave. Please thank Mark Tilden for me, too. Alright, let us clear the slate. Tilden says that Turbot 2.0 had FLEDs that influenced a...
