I thought it was $16.99 probes. megahertz smegahurts. I use fancy probes on low freq signals all the time. AND the circuit never complained - even once. spinnaker Joined Oct 29, 2009 7,835 I thought it was$16.99 probes.

AND the circuit never complained - even once.
But I was thinking a couple of wires might do as well.

And he is almost paying as much for the probes as the scope!

Be handy to have in the car or when I do stuff with kids. I see they have a 30Mhz version out soon for $200, I may wait for it. thatoneguy Joined Feb 19, 2009 6,359 Not bad but their shipping is way out of line. They sell one for$80 with FREE shipping!

Otherwise, it is 49.99 for the scope, + 29.99 shipping, so you can save two cents.

What I hate is sometimes they apply it to each item. For example I found 40 pin sips for a dollar a piece. Not too bad. Shipping was$2.00 still not too bad if you ordered a number of items but the charge was on each item!

I used to occasionally nab bargains on eBay, best way I did it was to look at the newest listings and the ones that were about to expire that nobody had started a bidding war on yet.

When you learn eBay and don't totally rely on their clock some bargains can be found but I've also ended up with some stuff I haven't a clue what to do with. It's so easy to press that buy button especially before you get over what they call "eBay addiction" so always try to think "outside of the box" before you commit to anything.

A few things however I've bought and immediately resold. A properly written listing along with detailed pictures is a must f you're a seller.

Best deal I ever got was something like a 1KW variac brand new in box for about $50 + simple honest shipping, best sale I ever made was on an extremely unique Klystron tube that went to the University of Hawaii. Only had one bidder on that, went for$100 and I had to pack the heck out of it but the professor was kind enough (although it hurt) to find out he had placed a \$1,000 bid on it in case anyone else came along. At least it went to an educational purpose. SAS60B if anyone wants to look it up but I doubt you'll find much if any data on it.

I wouldn't know, but if that's a good of a deal as you say congrats!

One thing to watch out for buying ICs from eBay is there are counterfeits running around, same thing with caps - especially electrolytics. They may work as intended or they may not, perhaps at first but not after a period of time.

They are called BNC connectors and I think even radio hack sells them.

Until you get a probe to use, a piece of wire will work just fine if well under 1 MHz. Just strip it back a little and lay it straight on the end, then 'poke it in the hole'. should come natural to you.

Merry Christmas
In the pic of your link it looks like it comes with the BNC connectors, and plastic tips for probes; minus the wire.
Radio Shack or any good parts store should be able to help you put together red and black wire, aligator clips and or probes. Not fancy, but you should be able to see some waves.
Thanks This is kind of what I was thinking.
