And the date is..... March 31st :) https://www.eevblog.com/forum/blog/eevblog-1677-an-interesting-effect-with-fuses-(experiment)/msg5866735/#msg5866735 Not in OZ. They are first for the new year too... Nope, we Kiwi's beat them to midnight by 2 hours minimum. Perth in WA is a further 2 hrs behind NZ.

Smithsonian should I ever hang up the hat to have the time to go to the US for a week or 3.....probably would hunt out Mike and Paul while there too....

Mike, darn it, it's not like you to throw in the towel !

Are the actives socketed ?
Do you have a transistor tester ?

Has it passed the CAT scan Mike ?

No outside walkies for Harley then ?

Best wishes to you all from NZ and Siglent HQ.

I'm going to check it out on the bench tomorrow out of curiosity and see if it comes to life on reduced voltage the way the other one did. Famous last words. Football practice went for two hours instead of one and I was wiped out. Then the weekend was over and the work week began and that was exhau...

Yup with EU plug.
Scored one similar locally for my 131 that came with the 110VAC PS.

As for welders, I have four:.......... An R-Tech Chinese 180 Amp inverter MIG/MMA welder. It came with a five year collect and return warranty. I haven't used it for a time, but it paid for itself welding patches on my Ford Mondeo, now gone to that great car park in the sky. It goes down very low s...

Stickiness draws newbies attention, and indicates that the thread has important information with a long lifetime, that will be of interest to many people.

Making the thread sticky was, IMHO, ill advised. Moving the thread somewhere was not something I noticed; I just use the "new replies" and "new posts" buttons. The "moderation" was a mistake and a bit heavy handed, but not especially surprising. The mod apologised and ...

It became far too cumbersome as a single thread . For instance someone might start a discussion on restoring an HP spectrum analyser, where he got stuck because a plastic cam switch was broken. That would turn into a discussion about various glues, whether it could be plastic welded, whether it cou...

add a 2S LiFePO balance/protection board, done!
Do you agree?

I do but Chris seems to want the easy way out with the least investment.

Yes a good idea that! Further thoughts to ponder on: Scope ON = solid color LED and/or flashing if being charged. Scope OFF but charging = LED in a flashing state, changing to a different but solid color when fully charged. It's getting whatever the shite charge controller does out of the box :lol:...

............. The intent with this is to "modernise" it. The original design is a 7.5V 4Ah (30Wh) supply which gives 3-4 hours of operation. We can do better than that now. So what I am probably going to do is the unthinkable and eviscerate the entire mains front end from it right up to t...

So you have it now and done some preliminary investigations but where are the pics ?

Yup, Aussie is massive and on our occasional trips to vk6zgo woods, 4 hrs of the flight is across Aussie.
Never done any of the east coast or NT and have little desire to.
Perth @ Xmas @ 40C is quite warm enuf.

@vk6zgo, if we haven't both carked it by then, a Xmas 2025 catchup ?

Reminds me of a gal I worked with years ago who told me she was going to East Africa for a holiday. I asked if she'd arranged insurance. She said that had been done through Endsleigh which used to be the Students Union insurance company. I said I was thinking more in terms of a 600 nitro express an...

Dusty but better pic from Tek wiki:

I have a 3-piece Datron calibrator that I really ought to get to work. While likely not the same model there may be some tips in Defpoms Datron repair series: https://www.youtube.com/playlist?list=PL2z3V9RkHQE0-wHP-8mjjDsQJR3OgwElR Oooh. That's recent. I'll have to look. Thanks With luck they will ...

Yes working on that now. It's all being pipelined into eBay carefully at the moment or disposed of. Nothing is worthy of the auction house as such. As for the jaunt, I'm trying to trade it off against jumping on a plane somewhere more interesting for the weekend for about the same price before it g...
