Finally found a cost effective replacement for dead instrument panel for my Polaris ATP 500 ATV.

I bought this 2-meter long NOS GPIB cable on eBay for 30 Australian dollars.

A new desk, bigger, deeper and with electrical adjustable height.

You need more toys to fill all that white space.

SDS3000X HD will look great on that bench. 

[Martin72]

I'll have to come up with something for that too....

Got what I considered a decent deal on a range of generic Chinese soft multicore wire. My current lowish remaining stash is stored in plastic bags in a tub and is always a nuisance to drag out. The 10 and 12 AWG can stay in the bags and the rest of it will move to small spools like my other general hookup wire. Under 2 weeks to my door https://www.aliexpress.com/item/1005005048098404.html

Fired up Fusion and now off to the Laser Cutter to make some storage/dispenser racks for them. Still need to make racks for my hookup spools now instead of the vertical stack that gets toppled frequently

A TechniSat "Internet radio receiver" for my "older" Onkyo surround receiver in the summerhouse.
https://www.amazon.de/dp/B087XNQK7Y/

FM reception is really bad there, and this one does an excellent job.
Easy to use & setup , nice remote , and with BT too.

I actually have the parts for a "HiFi Berry" laying around , but the wife would never be able want to use that one, she'd want a remote & a LCD.

A bit pricey, but worth it .. To keep my THX Certified "Work horse"

The battery in my multimeter leaked, so I bought a pack of 2 rechargeable lithium batteries.

How is the output voltage ripple on these?  I have a current probe that takes 9V batteries that I always forget to turn off so I'm replacing batteries on that thing way more than I want to.  But I'm pretty sure that probe would be sensitive to the output ripple if I tried to run it off a supply/dc-dc converter instead of direct from a battery.

Has anyone looked at the output of one of these?

The noise on its output looks terrible. The upper part of the picture is measured with a load current of 10mA, while the lower part is measured with no load.

Sorry, I don't have any current probes so I can't do the test you're expecting. However, there's no noticeable problem while using it with my Keysight U1253B, Fluke 117, and 83V multimeters, except that its slightly larger size makes it a little bit difficult to fit into the U1253B.

wow.  glad I didn't pull the trigger.  Thanks for checking.

Au Vide Grinier aujourd'hui....Porte Royale

(at street sake today)

Ultrasonic cleaner EU2
Touch lamp w/ LED bulb EU3
German WWII aviation calculator like USA E6B EU 12 VERY rare!

You always seem to find interesting street sales.
I don't remember having such luck when I was in Paris.

Mille mercis....Like Ham Radio (ARRL) fleas, the best sale locations, dates, and times in Paris are not so easy to discover.

It took me many years to discover the Vide Grinier (neighborhood sales0 and best Marche au Puces (flea markets)  in Paris.


Enjoy,


Jon

I found this JVC micro component system at Renaissance (I guess that's Goodwill in the US, I just noticed the small Goodwill logo next to Renaissance at the store)
As a sculpture it's representative of the late '90s early 2000s for me. I have a great affection for miniature things like this, especially speakers. These are real nice.
No cables, no remote, it powers up but the fluorescent display is very very dim. The volume knob is motorized so that's cool! I also love the style of the top loading CD.
On the display shelf it goes!

I bough a slightly used a Rigol DP832. Unfortunately the auction house got rid of all the calibration certificates and labels, but I got the accessories and the manual with it, which is really nice. I still have to calibrate it and load test it, but otherwise it looks to be in very good condition.

A 100 meter drum of 7/0.29 (2.5mm² cable designed for use in conduit) .or put another way 700 meters of copper wire that's the perfect size for jumper wires on circuit boards for around a third of the cost of the pretty tinned stuff.

Finally after several years of "hunting"

When I review Electromagnetics, I always bump in to trees. Trying to find the forest.
Maybe this book will help.

Just re-cal yourself, it will be way better than factory anyway, as you can add additional cal points. There is a script to automate the procedure, manual takes way too long.

Wow, congrats. The king of multimeters.

I meant calibration the metrology way, checking if the outputs, noise and measurements are within specification.

Yes thats what I'm referring to. I don't even remember mine coming with a cal cert with any sort of detail at all. Better to do it yourself, assuming you have a half decent DMM. https://www.eevblog.com/forum/testgear/dp832-calibration-using-python-pycharm-running-on-windows/
If you don't, then spot check with a handheld multimeter and leave as-is.

For anyone else tempted by this, note that it says 50m but that's total, so you get 10m of each colour.
