I am more about horsepower than voltage (one of those mechanical guys); however, I could have a sacrifice in amps to increase the voltage, for it seams like this diode thing is all about power & getting those little critters (horses) to jump the np bridge (exceed the threshold voltage). I seem...

Problem with using a higher power solar cell is my space limitations. It seems like it’s pretty much linear, higher power- larger the cell (not to mention $$).

Thanks for all the feedback! Yes, this is an L.E.D (red so far, lowest voltage I found), and I was not aware of the lower .2 V on the market. I thought for the whole npn deal to work, each L.E.D is within a fixed range of voltage, therefore determining the color of light. I’ll look around for...

How can I increase the voltage output on a solar cell from .5V to 1.5+V ? I would like to do this without adding additional cells. Is there a way to do this with a transistor charging the primary coil of a transformer? If so, any idea what type of transistor would work? I would like the...

I’m working on a design for a simple mechanical device that will disperse objects at a precise fixed distance entered on a control panel (i.e. every 2 ft.) The machine will roll on the ground. Would connecting a plc to a rotary encoder device be a cost effective way of measuring distance...

Microstation Solid Modeler is by far your best bet compared to Acad and Solid Works. I used it for 7 year. AutoCad is out.
