Hey, that would be nice. I saw your message re. the Freon gas and not beingable to ship it. How about if you send your probe to the US and someone fills itwith the 114 gas (100 cc) and ships it back

Tom I have 47 & 100 ohms 2x1mm size , if you like I will be very glad to send you as a gift the 3 resistors. Regards Gabriel.

The closest I know of is "Modeling the Bipolar Transistor" by Ian Getreau, published originally by Tektronix in 1979 and often given away to customers. It's available from Lulu.com, now. The author

Yeah, I love that Chinese "free shipping." Every "free shipping" piece I've received from Shenzhen has had a falsified Customs value declaration, and the difference between the declared value and my

Unfortunately for me, this guy not ship outside USA, you USA fellow could enjoy refill your P6015 at reasonable cost. I strong recommend copy and past the complete and usefully instruction about

Thanks. That seller is really being misleading with the add and thus thesearch term failure. The "free shipping" is on additional quantities after thefirst item at $1.99. It is definitely a 50 ohm

I got a SD-26 sampler head for somewhat cheap because it would not calibrate on the A channel. A quick look at the input with a SD-24 TDR showed the input impedance was around 2.6 k Ohms. The other

The 7CT1N curve tracer plug-in is for a friend which moved into a very small apartment -- he is using a 7633 scope in his bedroom! I will forward all responses to him. Just for the record, he is not

I've always used AllSpec, but Uline has less expensive static shielding bags in quantity. AllSpec is used by the DoD for bags - we used to see them by the thousands in our module repair

Hi Dennis- Can you recommend specific books or web source that might assist the non-engineer to learn some of the practical uses for the 575? Yes, there's lots of info out there, and this forum is

Funny, I was working on just that function when I got sidetracked into doing a couple of small Android apps. I don't have a lot of faith that the ESR function will ever work well in

That is astonishing value for money! Want one.... Craig

While many of us here would love to have a 576 it's simply not in the budget and many will not want to repair one if purchased needing work. I've been saving up to buy a Peak DCA55 component analyzer

Thanks David, a valuable reference, those three "spare" transistors are very handy. I also had a look at the LM10 OP-Amp/Regulator IC which was mentioned via one of the forums recently. I guess

It is in National Semiconductor Linear Application Note 256, "Circuitry for Inexpensive Relative Humidity Measurement", although I was wrong about how it implemented the temperature measurement.

Haha, yeah Craig, you guessed it. I was literally born in silicon valley (back before the traitorous eight). My high school had a PDP8/E, the usual 1978/9 micros and a link to a HP2000 at the

I think with a little hot-melt glue, you can tack the board to the plastic part. > Ed The plastic is made of Delrin. It is nearly impossible to glue it. Nothing will stick on it like Teflon. You will

========================================= I 'm surprised at how much these go for, considering it's basically just a keyboard. I remember back in the late '70s when the local computer store was

Hi David, do you have a link to the circuit using the LM389 please, I'd like to see how it's used. Thanks, Don Black.
