Ja, small linear error from using straight shaft. There have been several attempts to avoid the issue by using things like lobes on the drive, but by far the best solution is to bend the shaft in a slight arch. works extreemly well. No need to correct after 10 -15 minutes run time. Bigger...

"The difference between a laser being "off" and being destroyed by too much current may be only a few 10's of millivolts and it is for this reason that all laser diodes have some sort of current regulation scheme incorporated within their operating circuitry. " Hmmmm,,, OMG!!! Cyparagon, how...

As per Mario, Forget about "G". Use whatever variant of "C" you are familiar with, and will compile to a hex file that PIC chips will understand. If you are good at C, you can look at some sample apps, available at Arduino.cc or sparkfun for how to structure the logic and adapt it to your C...

NO4H99 is pretty much spot on. And NO, NO, NO,,, The ISS and most sats are NOT in the normal atmospheric envelope..... Jeese,,, If they were, the drag would make the loose velocity and fall into earth, or more likely burn because of the friction. There is a lot of dust and other particle out...

"When I install it into my machine and connect the gate to a 5v led output that is tied to the Z axis direction pin it will turn on and then not turn off once the gate is disconnected" Are you actually disconnecting the Gate, or are you assuming The voltage on that line has gone to zero when...

"Behind Victory Garden Walls" If you rember that version, youre officially 'a Geezer'.

Ten's of terawatts,,, cancer therapy,,, O.K. if we fry the patient, there won't be anymore cancer....

What does that have to do with modulation? Ya gonna twist the wiper on the pot to modulate?

All that just to pop some balloons?? Ach, du lieber!

Most impressive design and execution. You truly deserve the moniker of 'Wizard'. But, heed the warnings about where to measure heat for determining safe runtimes. You may run it for a very long time without noticing any degredation in performance or heat in the host while diode and substrate...

Does anyone smell a troll?? , or, maybe a Smurf....

Rouge, Seriously? 1 Watt of near I.R. pointed at your knee? I'm afraid that's gonna remove you from the 'patients who do not want surgery' category... Have you thought about crystal therapy, or maybe, the put a raw egg in a saucer under your bed therapy? More realisticly, the surgery isn't that...

Ladies, ladies,,, Do some reading. In most cases,,, If you have a DPSS (cheap Green) pointer, it uses a I.R. diode as a pump, and almost all of those modules are case positive (the button on the battery (+) goes to the end cap/case. If you have a blue or red, it is likely NOT a DPSS (too...

Must be a theoretical physicist....

Try replacing your IR rcvr module with a plain old LED. The clear ones work better, but any will do.

My, my, someone's a winer....... In the immortal words of the Great Dave, "Don't let the door knob smack you in the butt..." Cy, I don't find you pretentious, maybe an ass at times, but almost always right.

Sounds like a good way to melt a linear regulator....

If you're not crying to get your $20 back, then why did you post the above? Your rep= 0, jeff's rep= 450+ Harley DaviDson= Motorcycle, Suzuki= 2cycle, oil-burner, motor bike.... $5 for a can of beer= stupid....
