I prefer nipple, pair of them, thank you very much :-P

LOL I'm a Year 9 student in Sydney and would love to have the Fluke 8060A, but I can't post pics of my workbench - it's practically empty (I did attach a picture of my very messy spare parts drawer, though)!
Why do I want it? Well I don't really have a lot of money, so it's difficult for me to buy gear to develop my electronics ability. All I've been doing for the last few months is salvaging a lot of parts from blown PSUs, computers, etc. and saving enough money to buy other components that I can use. 
EDIT: never used a trackball, nipples are better

Yey, Dave gave some love to Keithley DMM finally 

Interesting voltage reference box. Wonder only why custom module was designed for reference, instead of using common LM399..

This was a great mailbag and I did notice that the audio seemed a bit harsh early on, I blew my nose and it came good, probably my end I suspect.

One of my customers works at  hospital looking after instruments and re-stocking medical stuff and I once asked what they did with those alcohol wipes when they are out of date, he explained that they discarded them so I told him to get me some next time around, anyway one day he rang and turned up with a few thousand but I'm now down to a few hundred left, if people dont know where to get them they could perhaps ask their local GP for out of date packets although recently a neighbour did point out that the local supermarket sells them down here, I'm happy with my current supplier.

Put me down for one of Ian's voltage references if he decides to sell them, I did read about them on another thread and visited his site, very impressive and just what I need.

Many Thanks

Muttley

Thanks for the good words on the Voltage Reference Dave.............yep, I have been thinking about making and selling them. I have yet to work out a price based on qty parts so not really sure about pricing yet.

The heater is a bought in item, it's actually a QH40A crystal heater - 40.8degC, +/-1.5degC, 0.1degC resolution. It REALLY makes a difference in stabilizing the Vref.
The Vref itself is a MAX6350 5vdc output, 1ppm/degC and kept stable via the heater.

The panel lettering isn't letraset, it's engraved and paint filled.............needs to robust what with the amount of wild Haggis on the loose here in Scotland!

Nope, the audio sucked.
It was better when I was away from the mic, but up close behind the cam the auto mic gain doesn't work well. quite harsh compression.

Details, details, just start selling them!

Ah, interesting, thanks.

I felt it was raised, that's why!

Do you have any long term data on the drift perfromance?

[EEVblog]

I got mine from the local chemist.
Cheaper on ebay though:

Not yet but I will look at that soon, the dang day job keeps getting in the way!........probably need a better DMM first. I only have a couple of old Keithley 2015THD (6.5 digit).

Good enough, the 8060A is all yours, may it serve you well.
Email me your snail mail address.

Thanks, it's an honour! PM sent (the email link doesn't work for me)!

Hmm, you are right, the email icon under peoples user names doesn't work... 

[SteveLy]

Congratulations crispy! You got yourself a classic super accurate meter there. I can't get over how after 30 years and obviously a lot of use, it's still dead on ~100ppm accurate on both voltage and current: an order of magnitude better than spec. Amazing!

[Artlav]

ODB adapter that didn't work, you say?
Sounds like the NSA just succeeded in installing an exploit into Dave's car, and now it is at their mercy. 
( j/k, but seriously it might be just a matter of time before someone sends something nasty into the mailbag... )

[redshift]

Dave, you do realize that Istanbul is in Turkey right?

[zapta]

The Foscam C1 is only $70 on Amazon (free shipping for Prime). If setting is smooth for the average consumer (a problem with previous Foscams) it will be a hit product. I am going to get me one.

[technix]

Man I wish I can get that multimeter... Too bad I am in China, and have to drop about US$400 to get a Fluke 87-V/C. Dave next time I am going to send you a dummy load.

Nice episode. 

Dave forgot the link to the AmpHour episode with Dr Taylor, designer of the Fluke 8060.
Here is the link.

The audio was ok for me  and to respond to the poll i prefer nipples 

[chriva]

Nipple. definitely nipple.  I also own a stinkpad

A QZERTY keyboard on the mac, first time I've seen one and had to look it up.
The interwebs says it's Italian so that makes sense of the gui language also.

[kahvikello]

I'm no aussie but here is pic anyway x3

And yes I love vintage gear! awesome
