CandyLand Posted September 27 Author Share Posted September 27 (edited) Hey Mod guys...Feel free to pull that video down if you want, Before someone around here gets hurt. Edited September 27 by CandyLand 1 Link to comment Share on other sites More sharing options...
needlebat Posted September 28 Share Posted September 28 It behooves me to say I also trust my training and skill to keep me safe when a barrier would be way better 🙂 Maybe we should start making videos of common experimental setups, and devote the whole thing to pointing out the many ways the devices can disfigure, maim and kill the tinkerer 🙂 Link to comment Share on other sites More sharing options...

CandyLand Posted September 28 Author Share Posted September 28 (edited) Well it diddnt hurt as much as you might think, (*although my arm was sore a few days) But it did happen fast...Aparently a faulty tube like that is quite rare, That is the only time I have actually ever seen one in fact, But Yes it was quite unpredictable and bit Baby really hard.

CandyLand Posted September 28 Author Share Posted September 28 (edited) That damn machine, I still hate it, It was a Ms pac that came to me because the owner said it was haunted (*seriously), Aparently they felt "watched by ghosts when they played it)...My thoughts on that after all these years later is, it was probably generating excessive radiation and most likely shooting Xrays all over the player for extended periods of time...I diddnt actually test for that at the time, but after working on that tube (and finally replacing it after the fourth time), Ya I have no doubt...It was ugly.

CandyLand Posted October 26 Author Share Posted October 26 (edited) Finally my new *(old) voltmeter showed up...It seems to need a little maintenance work (and probes), And quite complex as the scale appears to be in DBm at specific frequency if not complicated enough I will figger it out, Exciting and fun though...That 75ohm is a bit concerning on my bench however.

CandyLand Posted November 10 Author Share Posted November 10 (edited) This is disappointing as hell, And after all the trouble I went though to get that on my bench, Initially this was to be one of the machines needed to calibrate that VNA, But apparently there were two different versions made and this one just happens is the 75ohm, The wrong one…back to the drawing board. Oh, I guess Princess already talked about that earlier (Sorry for the double post on subject )… But good news is I did manage to find the update software on the analyzer, and a new floppy drive to burn it to the 3 disks.

CandyLand Posted November 15 Author Share Posted November 15 Hopefully that’s the last of the manuals for this thing found 2 on the subject of programming with BASIC And two more service manuals , For a total of 7… The latter was kind of an eye opener and certainly anything but fun reading… The VRAM memory doesn’t seem to have any special concerns so batteries are in the mail… For you buy local guys, I only got three of them, but the shipping was over twice the cost of the parts, (locally) So it not just America “Out to get you” its across the board… Granted shipping Lithium in any quantity has its certain constraints, But still. 1 Link to comment Share on other sites More sharing options...
needlebat Posted November 15 Share Posted November 15 Madam, with occasional exception, the argument has simply been that (1) due to distance, most products available to Australia attract significant freight charges, and that encourages a 'buy local' mindset; and (2) many US (not America) companies don't bother to optimise freight to Australia. You are a smart cookie, arguing from the specific to the general is not how statistics nor rational argument work 🙂I expect poking detractors takes precedence 😉 Is that the full count of manuals available? It would be nice to have the set, for your set, see what I did there 🙂 Link to comment Share on other sites More sharing options...

CandyLand Posted November 15 Author Share Posted November 15 Ok, Ok you guys do make a point, And Jennifer regresses, But it should be mentioned imports and tariffs are actually a thing and whoever is writing that check so you can buy locally is obviously passing that cost on anyway… As for the manuals OMG, yes I hope that is the last of them That is a certain Hell I would wish upon nobody, If you get into Network analysis I would strongly suggest the nano VNA *( Reputable dealers, beware of counterfeit) for hobby level testing, Basically the comparisons are quite negligible And the cost difference is almost embarrassing. 1 Link to comment Share on other sites More sharing options...
needlebat Posted November 16 Share Posted November 16 I'd like a super-cheap digital oscilliscope - I'm surprised there aren't more low accuracy units around. Might not be a market for the super-thrifty end of town. Link to comment Share on other sites More sharing options...

You can get a pretty nice old analog unit quite cheaply if you shop around multiple even for less money as they are pennies on the dollar, (ya sometimes I smoke them, don’t be so judgmental, Lol) Those fancy digital units look fun but personally I have never really been a big fan,And still love them old scopes.

needlebat Posted November 17 Share Posted November 17 My apologies for the vague, its the 16 digital inputs and trace I find attractive. And old cro is fine for most jobs as you say. 16 inputs with a trace would be great for my microcontroller projects. Link to comment Share on other sites More sharing options...
CandyLand Posted November 17 Author Share Posted November 17 (edited) You don’t need to ever apologize to me, I get the feeling of random comments in the night while working on something There is benefit to digital, I am not all one or the other… Upgrading your workbench in one capacity like a new scope, generally speaking is opening up the door for more better instruments and equipment just to justify owning it in the first place, And the pain is real, (Says the girl with a giant Network analyzer in her kitchen )The workspace of a curious being shouldn’t just stop at a certain point however or you are actually limited by your tools not your knowledge… You can do it, Just make it so.

CandyLand Posted November 17 Author Share Posted November 17 For everyone else, Well don’t just run out and buy stuff, That happens over a lifetime as you need it and grow… Jennifers bench is about to get some radiation detection equipment, Mostly in the EMI/Xray realm, Not something most would consider important for a workbench Just an example of the“progression”. And working with you voltages under vacuum. 1 Link to comment Share on other sites More sharing options...

CandyLand Posted November 17 Author Share Posted November 17 (edited) I couldn’t help thinking about your plight there Needlebat, and decided to take a look, And Omg the price of those Siglents have come down, Granted on low end it’s not the 16 lines, but even so you wouldn’t be sacrificing quality either… It’s actually quite a impressive value for the dollar, for being a 100mhz budget machine… And no hugs for you Hank, I need chicken or something to eat,A Cherry slurpy might get you a hug though …Just saying.

CandyLand Posted November 18 Author Share Posted November 18 I have never heard of 16 inputs however, That actually sounds like considerable/confusing cable and assuming that some kind of software trick… Normally the better scopes I have played with only have 4 channels and running all four is a bit of a challenge. 1 Link to comment Share on other sites More sharing options...

They are a handy thing for decoding computer bus issues - you can trigger from a normal probe, and read the bus data at the time - great when you suspect your analogue circuit is out of sync with the digital, or when Chip Select or some such is early or late. I've seen them as option on the PC based oscilloscopes, and on dedicated machines. Link to comment Share on other sites More sharing options...

After looking into that I have been getting a rash of Black Friday flash sales…You are right 16 inputs on 2 channels does look like a powerful tool… even on sale though it still comes in at 860.00(us), That is still a bitter pill, Link to comment Share on other sites More sharing options...

I've not looked to see if there are newer/others... Link to comment Share on other sites More sharing options...
