Grendels,

I took your advice on buying LEDs in bulk from Ebay; you saved me a lot of cash!

I checked out your 555 timer vids and had a question about purchasing capacitors.

Ebay has sellers offering a mixed bag of caps; should I buy those, if not  I'd appreciate any suggestion where to get them. 

Also not to clear on exactly which caps to get for 555. I believe you used a 10uF in the vid; is that what I need?

Thanks!
