Your just fine. 104 is 10 with 4 zeros or 100,000pf which is .1uf.

101 would be 10 with 1 zero or 100pf which is 0.0001uf. Where do you get the 101 from anyways?

Do you mean the picture in "STEP 3a"? I think he might have just pulled a pic off the internet and it turned out to be a 101.

Hmmm I'm confused myself . . . I took a picture of that cap personally and not off the internet . . . I just checked the board to make sure, and I definitely used a 101. Yet digikey claims I ordered a 104 . . . so long ago I don't remember what happened.

Anyway, the 104 will work too no problems.

The numbers works like the color codes on resistors (third digit is the multiplier). The unit is uF (micro-farad).

If there's no 3rd digit I get no multiplier? An "33" would be an 33 microfarad capacitor.
I've got an capacitor (actually 100 capacitors) that are marked "1.4" - is that dot an real dot or is it an defect? I doubt it's an defect because all of them capacitors got the dot. Does that make it an 1.4 microfarad (accounting the dot) or an 14 microfarad (ignoring dot)?
