Is a laser operated button pusher possible?

We have a business convention coming up soon. Inside of our display case we have this grid of LED panels. The goal of the display is you try and hit a button outside of the case when a certain LED panel is lit To demonstrate human vs. computing reflexes. I'd like to have some kind of external build to demonstrate with as the "vs.". I am thinking I can use a laser and point it at the LED block because lasers are capable of transferring data. I would think it wouldn't be too difficult to make a build that distinguishes between on & off. It's basic binary, on & off 1 & 0, true & false, same & changed. When the surface lights that the laser is pointed on, I think the easiest way to push the button would be to discharge a capacitor into a hobby motor, and some kind of tab or something on the motor. I can go into more detail on the build, but I need more info on making a laser operated trigger system thingy.

It has auto-answer option. But it has an USB port to connect the headset.

Looking to build a remote controlled mic stand

Want to build a remote controlled mic stand. Needs to have ability to hold 2 lbs and somewhat accurately make movements in increments of 1/8" at a time. I have no skills in building such a device. Looking to pay someone to build one for me immediately. I am very serious about this. I have seen others who have built such a device, but none worthy for sale as of yet. I wouldn't be past investing in marketing of such a device if something working comes of this. Jimmy

Battery operated led with 6 hour run time per day.

Trying to figure out how to make a circuit for a LED light that is run by two AA or two C batteries. I would like the light when turned on to run for 6 hours and then turn off. Then autmatically turn on the same time each day and run for 6 hours without having to manually reset the light. Having a hard time trying to figure out how to make this timer. It would also be a bonus if the the led flickered like a candle. Thanks for any help in the right direction.

I would like to have an industrial sewing machine motor operate on a removable and rechargable battery. Answered

I am in need of a rechargable battery operated industrial sewing machine motor. I would like to be able to switch from the battery to AC power when needed. Use battery when in the field and AC back at the shop. Typical sewing machine motor is: 2 poles, 130 cycles 50/60, 1.0 amps, 90 watts. It would be great if the battery would last 1.25-1.50 hours per charge and be removable to install a fresh battery and be charging the spent one. Thanks.

Need to make very loooong lasting battery operated Mini LED light for backlit painting

For some of you brainiacs Im sure this will seem like an incredibly easy project but for me, Not my area do expertise in the least. I need to make a simple machine for part of an art project. I need to have two small LED lights placed one each on the tip of two  clock hands . I need the lit clock hands to be battery operated ( looong as possible) and flattish ( maybe an inch in depth at most for entire piece) so it can hide behind a painting. Would like it to  operate lit up and moving in clockwise circle nonstop day and night for at least a year . Any ideas?  What # volt? How to make simple clock ( besides just buying a kit? It only needs a very long hour hand with bulbs on each end ( say 12 oclock and 6 oclock) Where to get small ( 1/8 to 1/4" diameter)  long lasting LED bulbs? As I said before, I am an absolute amateur here!  Thank you. Maggie
