And Now For Something Completely... ON-TOPIC!!!

It had to happen sooner or later.
Dear mnementh,
just because it is 'only' pressure you're measuring, you must not lose proper style!
816621-0816627-1816633-2816639-3816645-4

Mmmmm.....pressure!

PS1: And there is a infernal multitude of adapters to collect!
PS2: The absence of pressure is....vacuum. This slippery slope leads towards Penning-Pirani gauges etc.
PS3: You have selected the area 'fluidic properties' as your next challenge. After completing 'pressure', 'flow' and at least one other submodule must be completed before you can proceed.

It's all yours, dive right in!

There's an HP 6207B on ebay for a reasonable amount of cash. 0-160V 200mA. Considering it but can't think of a use for it. If anyone can come up with any let me know  :-DD

Edit: so far:

1. Very low voltage HT supply for tubes
2. Avalanche pulse generator driver
3. Wire it to the letterbox and electrocute the junk mailers.

4. Admire the small, fanless form factor and gold binding posts.
5. If you have any other 6000-series from that era, it'll expand your range. At least until you get a 6209B.
I TEA.

5. Got three already so it'll fit right in  :-DD

Sold. I will bid on it. Damn thing has a starting bid on it now.  :--

6209B would be nice. That and my 6284A has got enough juice to run a nice valve transmitter :D

I think it went on slightly longer than that as my 6286A has gold ones and that is circa 1977. I reckon around 1978-82 they swapped over. My 6236B has plastic ones :(

Might also differ depending on where they were manufactured as well.

Still works like new. Better than the Kent one made in 1985 I have.

Bargain for you Americans: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F202761849420

Heathkit tube tester $45. Looks like it needs a tidy up but not bad price. $400+ here! Only does old tubes though by the looks not the smaller base ones.

Heath TC-1. My father had a later model TC-2. Essentially the same and it's a simple emission tester and not much else. Oh yes, will check for shorts. Meh.  ::)

Ah, OK. My 6200B is too new with gray binding posts.

My TEA time is at a low ebb due to life getting in the way. Squeezed in a little CAD and 3DP to make a TEA adapter. The rear filters on this little commercial roaster are OTT on price so time to look at designing and making replacement inners to sell and maybe make a $. Airflow restriction needs to be similar to the real deal as it clogs with detritus over 30-50 roasts.

Easy transition to design when you know how and have the initial adapter on file. Another non bodge  ;)

Nice work. I haven't fired my 3D printer up lately because it generates too much heat inside for these 100 deg. days but come Fall I plan on doing some projects.

That's pretty cool bean. Makes me feel like getting a 3D printer. But if I wait a little bit, the feeling might go away again. Not quite ready, yet.

6209B would be nice.

Speaking of that. Check out this listing: https://www.ebay.com/itm/Agilent-HP-Keysight-6209B-DC-Power-Supply-Untested/273941738525

The seller brags about their techs being the best of the best, but they've apparently been bested by this little 6209B that is being sold as "untested." :-DD

Welcome home, bean.  ;) Kept a seat by the taco warmer for ya.  :-DD

What's this about "needing a certain amount of restriction"? Sounds like hooey to me; seems to me there's plenty of restriction in that pattern of slotted holes in the bulkhead to create a specific amount of airflow; I'm certain that is their express purpose. If not, you could print up an adjustable gate to go over the slots. No reason in the world you can't then make an airbox to fit a $6 CA9054 air filter for an F-150 in there. IIRC, those are approx 8" x 10" x 1" pleats. Oh, excuse me... approx 205mm x 255mm x 25mm pleats.  >:D

5mm thick filter to play with. To much restriction and you get smokey beans as the air doesn't flow from the drum as designed :P to little and you suck the heat from the drum so you will never get them roasted in a 'normal' time.

One of the stock layers is an activated charcoal not that it matters that much as you really can't roast inside. I do roast in the shack but with the door open next to it.

Edit: so far:

2. Avalanche pulse generator driver
3. Wire it to the letterbox and electrocute the junk mailers.
Did you snatch this up? The only 2 I can find are both state side?

It’s not listed by model name. Try “hewlett packard” in test and measurement category. Feel free to go for it so I don’t  :-DD

Oh I see, don't think I want it really, I don't do much with valves these days, made the transition years ago. I was only thinking of a 100v supply meter testing, but I have pretty good means of near enough calibration upto 100v with my heathkit oscilloscope calibrator which gives me 1mV, 10mV, 100mV, 1V, 10V and 100V outputs which accurate when compared to my meter calibrators. So with that in mind, your still in the danger zone, go on buy it, you know you want it, buy it,.... Buy it [emoji16][emoji16][emoji16]

Those images look great. I checked out some videos, too. Very clear, unlike the scopes from just a few years earlier. The ADSM302 is this year's model with twice the working distance (up to 22cm), but the 301 seems just fine (up to 12 cm), considering the lower cost, the same resolution, and the same frame rate.

Help me! It looks like I'm getting one, now. Order submitted. :scared:

I can't help you now it's too late.  :-DD

The base is solid aluminum but it's not great for laying a board on because it's too slippery-slidey. Just need to put on a material to help a board stay put. Looking at some options like a piece of ESD mat. I did some soldering with it yesterday and was very pleased with how it went.

Took another pic for you at full magnification.


Nice.

Now I officially hate you.    (Now, where's that link....?)

Here, especially for Down Under:

You're added to the list.

It's confirmed.... my hate list has earned new intensity.

Been looking at the ADSM301 and started thinking about a particular application where a larger focus range would be advantageous ... and because someone just happened to mention the ADSM302 - I found it is a better fit.

I just can't thank you all enough   ::)  ... but my bank account is cringing.

jep. I watched this video and decided, that the 302 fits better to my needs.
