I see what you mean. I didn't use a diode on my 555 circuit because you can vary the flash through one of the resistors. My circuit only has three resistors, one capacitor, and one LED, in addition to the 555. If I vary the value of R2 on the instructables LED flasher project, I can speed up or slow...

Lighting the TARDIS

I just watched a couple of guys cut a bunch of plexi into windows. They used an angle grinder with a cut off blade in it. I would suggest that a cut off blade in your dremel would work just as well. Draw your line and then make several passes until you are through the material. You will have lots of...
