It only annoys me if the lighting hits at the right angle ... just like when it appears in the photo ;D

I wouldn't be able to handle that. Even the protective plastic on logos and name plates that I don't even need to look at have to go before the device gets used.

Just picked up a DG812 from Rigol's Clearance Center. $215 total incl. shipping and tax. It's not a brand-new unit but comes with a 90-day warranty.

First time I've seen the the positive and negative binding posts next to each other on an Asian design power supply. Usually they put the earth ground in between.

I just got a bench power supply: Sugon 3005D.
And yes, the screen protector stays ^-^

I can almost (with maximum tolerance and open mindedness) understand people who leave a bubble free screen protector in place, but a screen protector in that state needs to go! How can you use something like that. Doesn't it annoy you every time you look at it? Why!!!???  :scared:

It's as if you are prepared to use a non-perfect setup for it's entire lifetime (with you) so that someone else can later use it in perfection.

Yep, my parents, starting from nothing after WW2, do use all their equipment with uttermost care.
They dumped an electrically dead vac cleaner after 25 years of use with a cable rollup in pristine order, because they never used the cable rollup to prevent it from getting worn. They used their 80s armchairs and sofa over 35 years and the furniture looked like new, when they needed moving to a smaller home. I had to dump it, because nobody, even the social shops, didn't want it for free because of the bulky 80s design.

It's really scary to dump pristine looking very old stuff. Kind of a weird time machine going mad.  :scared:

I like used thingies to reflect the use and to have some battle scars. 
So please remove that protector and allow the PSU a start into true life.  :)

Couldn't you find a local Hipster Café to take the sofas? Those places seem to appreciate such furniture, although maybe it would have been too clean for them?

Bought this little puppy alarm clock with radio. I was specifically looking for am alarm clock with amber or orange display, this one is perfect. The gentle orange large LEDs (or whatever this technology is) are not blasting my eyes at night when I wake up and look at it to check time. The best feature is the display is dimmable with a pot at the back of the alarm clock, I dim the display to very low brightness before sleep. The radio part is crappy but I do not use it, I switched alarm mode to buzzer. Also what is great it can display both the current time and alarm time. Not many digital alarm clocks can do that. The ambient temperature gauge is a bonus. :-+

Also has a 2.4A USB jack at the back for cell phone charging, but to provide that juice the clock needs to be powered from a walwart. I do not use that and just run the clock on 3 AAA batteries.

is an odd thing that most bedroom alarm clocks use the AM/PM 12-hour system,
however most clock displays on other electronic appliances are 24-hour or military time.

Somewhat different here in the US.  Here most devices I've seen are programmable for AM/PM or 24 hour system, but the cheap alarm radios only service AM/PM.  Well actually the coffee makers also seem to usually speak only AM/PM.

Got annoyed trying to find dev boards for higher end STM32s and ended up taking a bit of a splurge on AliExpress junk after most sources either turned up the bottom of the bucket nucleos and a few stupid priced evel boards.

I got a bit carried away and ended up with a checkout....

An STM32H743VGT6 Dev board.  Interesting choice of putting 8Mb of external FLASH on it.  An SCard, a TFT header and a camera strip connector.  Not the first video focused board I've seen.  Not what I want it for though, it's to play with the chip.
https://www.aliexpress.com/item/1005003989830214.html

An STM32F407ZGT6 Dev board.  Similar to the above, lesser chip, but comes with some interesting adaptions including an NRF communications module.
https://www.aliexpress.com/item/1005004389057711.html

A STM32G030F6P6 Dev board because I have a thing for tiny micros.  They make good christmas/halloween light controllers.
https://www.aliexpress.com/item/32828346568.html

An STM32F405RGT6 dev board I probably added to the cart before I spotted the 407.
https://www.aliexpress.com/item/4001016211320.html

2xF411 Black Pill.   2xF401 Black Pill and 2xF103 Blue Pills, because they were very cheap on the sale.  Might have got screwed on shipping though.

Now I just have to wait on these all arriving on the snail mail.

I think I got a fair range to try out.  I do need to answer a few questions on just how much / many audio channels and filters is practical with one or several of these MCUs.

Oh and I couldn't resist a few odd sensors and SPI Flash modules and microphones and.....  you get the idea.  I'm £100 lighter but it was a fun bit of late night retail therapy ... in a few week I get a good few evenings of play if nothing else.

Define what you need first then if any options are required as they can really add up !

The 100 MHz 4ch X-E is good value but if you need more the 200 MHz 4ch X-E and particularly while the SDS2104X Plus is on special, not so much.
You might come back with that's a 200 vs 100 MHz solution but it's not as the 100 MHz X Plus has a -3dB BW of ~185MHz.

I don't need anything specialised, just general purpose, in round terms, 100 Mhz, 4 channel, with individual controls for each channel, largest screen possible for that spec with no fixed menu's on the rh side, so all of the screen can be used for signal display.

Seems like you won't be getting a Siglent then unless you can get to grips with multiplexed vertical controls.

Everything seems to be heading that way and TBH initially I wasn't a fan of them either but quickly adapted when sent SDS1104X-E back in 2017 as a beta tester to now I don't really give a shit is a scope has multiplexed controls or one encoder for each channel. Surprised myself how quickly I adapted too.  :o

Much depends on how it's implemented as to what signals the scope UI gives you so to know which channel is active to the vertical control and IMO Siglent did a good job on that.

Although the Siglent does seem to prioritise the waveform output regards display area.  When you switch off the menus and aren't showing any of the pop outs, it really is quite bare with just 85% of the screen being the wave display.

Of course I haven't actually had hands on yet, so maybe I should remain a bit reserved :)

Other purchases:

1x  5x5Kallax shelving unit to replace the rather unbecoming plastic garage shelving rack I have in the office/lab.

also

1x  4x4 Kallax shelving unit which will sit on the rear of the electronics bench and provide a backdrop shelving matrix for equipment and close to hand supplies.  The bench is an Ikea work bench, it has a solid steel frame and the cantilever is only about 20cm, so I think it will be fine holding up a 15kg shelving unit.  If it gets dicey I can always support the table from below also.

If anyone seen my post about the state of the office/lab has got to, I felt it was time to force my hand and buy furniture.  I can't leave them sitting in the hallway for long, so I have to tear the lab down, replace the storage and hopefully find places for everything and can form some clear work space!

Christmas order to brother was a large anti-static, heat resistant, cutting work mat.  For lighting I am actually going to use a 100W LED white spectrum grow light.  It's a mix of warm and cold LEDs + some near IR that won't bother me.  It has a dimmer, thankfully because on full tilt it's like sitting under a cold sun.

Anyone getting close to or beyond 50 will understand that eyes betray you.  I have actually found my main issue is sitting in "relaxed and subdued" lighting while fine for relaxing, REALLY puts a strain on your eyes when trying to work with small things like electronics.  I bought a magnifying glass with LED lights, but quickly found that mostly the LED lights helped even before I used the lens.  I mean I work normally by the light of the monitor screen and a strip of 2W orange LEDs behind the monitor.  So, utilising the unused super bright lights from the Pepper plant hobby that's paused due to the cost of electric, should help me eyes!

Indeed that is true. Once the eyesight starts to go out, lighting helps quite a lot. A few years ago I got a good head loupe with three powerful white LEDs that made a complete difference even without the lenses.

It's the focusing. A bright light reduces the iris size and increases depth of field. You achieve similar by making a small aperture between both thumbs and forefingers and peeking through that, but brighter light is much nicer :)

A Cuckoo Rice Cooker - after a second thought with amazon I went to another online supplier. These devices say 120V but I'll be surprised if I will have to use my uk/us autotransformer?
