Replies: six Thread '"Sane" error margins for emotor torque measurement' TL;DR Summary: Involving layout simulation, prototyping and measurement, what are sane mistake margins for emotor torque? We're going to style and prototype some modest emotors.

Howdy, I'm wanting to aim a 275nm (with appropriate safety safeguards) LED that looks for being a couple of mm in size and width (The sunshine-emitting part) to a smaller dot sizing. The LED should in all probability be quite close to the area from the lens to collect additional of The sunshine. The dot dimension would hopefully be several mm or more compact.

Should the beam is elliptical and you really need a small round location, you'll be able to either tilt the ultimate lense, or you can test making use of a few cylindrical lenses to lessen the astigmatism. For illustrations or photos see:

I am undecided if Cell Relay will be suitable - the voltage is an analog signal, Even though the circuit that controls the relay might be digital.

2nd should be to always use exactly the same voltage (present will adhere to) but to flicker the LED (responsibility cycle, in terms of I'm mindful normally applied with PWM) on/off so fast You can not see it. Internet impact is The sunshine will get dimmer.
