Cool. Don't forget to add warning labels. "Do not try this at home." "Keep away from children." "Closed course. Professional driver."

 Came home from my business trip to Las Vegas to find my EEVBlog Bryman DMM has arrived. Pretty quick to the eastern USA (Pennsylvania).

My newest meter. Everything else I have is early or late 80's vintage Fluke.

A reasonably stable if dangerous DC voltage source so I can check the HP 3457A which will be arriving soon against my HP 3478A and Racal-Dana 5001 on the 300V range:

(Yes, I break them into smaller strings when left unattended!)

It isn't a good 9V battery sting until you made some SC sparks

Arrived during the week,  a Hickok design Tube tester I-177B (ex US Air Force), it works

Oh lord, you beat me with my 12 x 9V to get me a >100V DC source. KV divider at the ready. Good work!

You can have a lot of fun with 9v batteries:

Nice Scores Everyone

I got myself a Rohde spectrum analyzer, well its a protocol tester that has a SA up to 2.7GHZ+ RF generator + power meter included !

Well I just got my first Signal Generator an Marconi 2019, for 150€ deliver.
Guess it's not a bad deal.

Nice bits of kit. Very nicely engineered as well. I paid £10 GBP for mine ( ~15€ ). The guy was going to take it down the skip!?!?!

Make sure you leave it to warm up for at least 20 mins as they drift a bit to start with.

200ml of Galden LS-230. 90€ with shipping.
I'm going to try it with an induction hot plate and an asparagus pot.

A cheap Fluke 112 for the same price as a couple of fuses cost. Not the best backlight, no mA range, but otherwise fine.

[ECEdesign]

Student version of Altium for my project.

Some cheap HV DC/DC modules new on AliExpress. I had looked for this type of thing before but just found supposed 100kV+ type modules rather than anything useful.



High Voltage DC-DC Boost Converter 5V-12V Step up to 300V-1200V

also High Voltage DC-DC Boost Converter 3V-5V Step up to 200V-620V available.

I wonder what that obfuscated 8 pin SOIC is?

can you point a link to that thing??

I found it on eBay no problem.  Used "High Voltage DC-DC Boost Converter 5V-12V Step up to 300V-1200V" as the search criteria.  There are others, but I like the look of this seller:

http://www.ebay.com/itm/High-Voltage-DC-DC-Boost-Converter-5V-12V-Step-up-to-300V-1200V-Power-Module-/201472584304

I especially appreciate the inclusion (at no extra cost) of "self-healing insurance".     For $3 more the seller will 3D-print you a case with a "full toxic configuration" (see near bottom of listing).  I don't think that word means what he thinks it means.

Whoops! High Voltage DC-DC Boost Converter 5V-12V Step up to 300V-1200V

The blue 1.4 version seems to have some useful lower voltage taps and "self healing insurance" is still there (resettable fuse?)   

No toxic case with this seller though!

Would that high voltage step up be good for nixie tubes etc?
Or is everyone thinking jacobs ladder? Im usually fearful of high voltage.

I finally pulled the trigger on (hopefully) decent SMD tweezers:

Nice tool. If possible can you make a mini review?

It has a 300-1200V main output using a diode cap multiplier. But notice there are taps at 170V and 200V which should be good for Nixies. A 75V AC and 50V DC too.

I can do that. I've got the perfect goof-up to test it with.

My test equipment collection has grown yet again - I snagged a Tek 515A scope, and an ancient Triplett Model 1210 Tube Tester (more because it looks like it will be kinda cool cleaned up rather than for any practical purpose; it's from about 1936 or so).

Scope:


It has in interesting serial number (apologies for the blurry iPhone pics; I was too lazy to set up the good camera):


Unfortunately for the scope, some miserable prick bastard opened it up and pilfered all of the dual triodes out of it,    so I'll need to come up with (9) 6DJ8s, a few 12AT/U7s and various others before I can test it.  I suppose I should be grateful that they didn't strip it bare, but it still peeves me as any calibration it may have had went away with those tubes.  I hope their speakers blow!    

There are a few more photos of the scope showing the dust & empty tube sockets along with a quick overview video at https://pmanning.smugmug.com/Electronics/Tektronix-515A-15MHz


The tube tester at about 80 years old is in rather rough cosmetic shape, but I think the panel will clean up nicely with some elbow grease and various cleaners/solvents.  The enclosure will need to be re-covered to make it presentable as a good bit of its outer skin is missing or peeling up.
