Marconi 2024 9kHz-2.4GHz signal generator, arrived this morning, fixed in 30mins by replaced a capacitor in the power supply. I have to do some cleaning later
Nice, looks very similar inside to my Aeroflex sig gen (no surprise), any chance of some board pics?
HP 8656b signal generator... for no reason other than "I didn't have one."
Have to say, a bit pissed off that the seller sent me a different one than pictured even thought the listing specifically stated item was the one pictured. Despite that hiccup it's spot on and fully functional and only cost me $150. Now I'm trying to decide about kicking up a fuss and getting my money back or just moan about misrepresenting the item in the feedback. The issue is if I send it back I run the risk of yet another bait and switch and may end up with one not nearly this functional/decent of shape for so cheap. Pretty sure the dude was just sour I won his nicest one for cheap so he sent me what he thought was "fair"... man I hate ebay sometimes.
If there aren't any serious issues with it, I'd probably opt to keep it and moan in the feedback. Although you're well within your right to push to get the unit that was pictured, the seller could still leave you short in many ways, including making you send back that one, then claiming the correct one is no longer available and cancel the transaction. I wouldn't take the risk nor go through the hassle. You got a great deal. Of course, if you're not happy with it, I'll go the extra mile to relieve you of the pain and suffering at that price!
Enjoy it!
Send him a message and ask for a partial refund

Well... The seller refunded me $75... So now I have a 8656b signal generator for a grand total of $75... Shipping included! Havent been so pleased about being ripped off before!
Damn!! Where can I get ripped off like that?!? Congrats!

Owon B35T - works well, cheap bluetooth logging
. Obviously nothing special for input protection, but works real well. Takes 2 AA's, has a nice crisp display & backlight. Tested against my voltage ref, bang on. Good stand and feel to the meter. No complaints at this price point for low voltage stuff.
Fluke 8010A DMM. Ebay purchase. Described as powers up only. I took a chance because it didn't look physically beat up and the price was right. Received it yesterday and it is in good physical shape. Electrically is a different story.
Upper DC volt ranges won't calibrate. AC volts is totally FUBAR. It's stuck on over range. Ohms is OK. Oh well. I have the manual plus schematics so this will be my next project.
Found on evilbay a Rigol ds2102a for 600.00 US! Borrowed and stole to get it as I have been looking for a DSO to replace my old Tektronix analog. He says it is in great condition and works. Not sure if it has been hacked or not but for that price I think I can deal with it!!

Technically not purchased today, but arrived today.
A couple of months ago I signed an agreement for a complete upgrade of our company WAN nationwide. Part of the offering included ISP connectivity replacing our existing provider.
The connection was changed over last night.
Nelson to Sydney figures below. I am pretty please with the speeds.
Please, no complaints about getting access to EEVblog because I am hogging bandwidth to Sydney…
Does it come with the signature Australian data cap, so that you can bust your 25GB/month in 4 minutes?
Just got a DS1054Z, still searching for a few other basic pieces of equipment.
An Aven Mighty Vue Magnifying Lamp - practically stole it
Just some DRAM, to upgrade a couple of PCs. 8 x 1GB DDR2 2RX8 PC2-5300E 667MHz DIMM.
They are ECC, but far enough behind the size curve that they were quite cheap. Au$12.20 for 2.
The module is DPS3003; about $20 on Aliexpress.
up to 30v (with the right input), 3A. I'm only feeding it about 14v, good enough for the digital stuff I do. Previously I had mod'ded the the same PSU with a 7805 to give it just fixed 12v and 5v, but I found myself doing 3.3v stuff occasionally, and this is also nice having the meter on the front. Accuracy isn't perfect, but +/-5% is good enough for me (I can hear Dave shuddering at that statement)
The only thing I don't really like is it's click through for each digits, I'd rather just have velocity sensitive.
Just got an email from them, and they have a new module coming out. Looks similar, but it has a separate regulator board w/ fan, and supposedly up to 5A (although I wouldn't run it at that). If you're building yourself a small powersupply, this would work nicely.

I am now working on power over fiber based on multi-junction silicon PV cells (the wide band gap InGaAs/GaAs/Ge rubbish won't work).
Luckily I saved up for enough money to buy a fusion splicer, and I have access to a clean room (crude fab with silicon/SiC/GaN/GaAs capability).
After this power over fiber project I will probably move to fiber medium lasers, focusing on short wavelength, for direct power device firing.
Is this related to your power inverter project? That would be very cool.
