Reply to "Semaphore and 555 Timer Circuit"

I probably should have waited for the MOSFETS to arrive, they are still not here and the ebay listing said guaranteed delivery by June, 26th. So much for the 'guaranteed' delivery date. 

I bought a kit on ebay and built one of the 'transistor testers' which has worked pretty well so far. They are pretty inexpensive and can be found lots of places. Since I don't know the resistor color codes, that's how I check all my resistors to make sure I have the correct value. These are neat little devices, what will they think of next?  I find it to also be fun and relaxing!  

Of course that won't help my already ordered PCBs, if the actual part's don't match the schematic. Another problem with ordering on ebay is you don't always know what datasheet matches the part you are ordering. While Stan and others here can probably determine what they are getting, that can sometimes be a crap shoot for me. Keeping fingers crossed that everything matches up... 

This transistor tester looks identical to the one I have.
