But can it run Doom?

Why else do you think I went for the 5600G. 500+ FPS on 640x480 I reckon while this mini will likely peak at 1-200. 

I have actually done some testing with the Ryzen at 1080P you seriously could game with it providing you keep the settings wound back, hitting 60+ FPS wasn't hard to do on slightly older titles I had on a SATA drive I dropped in for a play.

If those HP G2 mini units give you trouble by shutting off randomly, you can try upgrading to the 95W adaptor (still really cheap used). That's how I salvaged a couple from the dumpster, they were "faulty".

They idle at like the 8-10W mark so I used to use it for 95% of my computing before I upgraded to a M1 Mac mini. My old gaming PC (or even a modern gaming PC) still idles at something stupid like 60W or so.

Wanna mini PC that can fly, try a ASRock Jupiter:
https://www.asrock.com/nettop/Intel/Jupiter%20H470/index.asp#Overview

Intel(R) Core(TM) i7-10700 CPU @ 2.90GHz  16.0 GB RAM with a 500GB SSD and about the size of a small box of chocolates.
CPU benchmark = 16,694

Selected for the greater than others # of USB A ports plus a good # of USB-C also.

Now a year about since getting it when the company workstation went tits up in the middle of a lockdown !

Depends on which century you live in.

Well, I have it running MX Linux and I can play Quake on it so I'm pretty happy with it at this point.

My LiteVNA was delivered today and first impressions were a little disappointing with the details on the plastic case.

[paulca]

I was just about to post that I bought a new Mini PC, but I see others beat me to it!

Grabbed myself an HP Elitedesk 800 G2....  not what was delivered.  An HP Prodesk 600 G3 arrived.  Almost identical spec, looks nicer, slightly more recent, better memory.  Bonus!

£115.

Idle power:  6.5W
Installing Windows 13.5W.

Supports 4K 60FPS and ultrawide IF and only IF you are using DP or a proper active DP adapter.  It wont do it through a passive adapter, as it drops to HDMI specs.  I believe the port can detect the adapter, a DP++ port.

Not electronics -- actually it is.  I have been waiting for the next Nikon sale to get its Nikkor Z MC 105mm (macro with stabilization and autofocus).  I hated trying to photograph my little projects with an older (Y2K) Canon point and shoot SX100.  That came to its righteous end when it fell from my tripod onto a hardwood floor late last year.  In the70's, I had acquired a Nikon F in Hong Kong and eventually got the 55mm macro for it.  Once installed, I almost never removed that lens. Of course, using 35mm film is just not practical today.

The current 55mm macro for Nikon Z doesn't have great reviews, so i popped for the 105mm   Sure, a little bit of overkill.  Attached is my first image taken with it.  Hardly any attempt was made to steady my hands, focus, or not jerk when pressing the release.  I am impressed.  VR and autofocus do work.    The center footprint is for a TQFP44 chip. BTW: For a lot less you can get a good D70 and 55mm AI lens.  Not much advantage paying for useless pixels in the D80 or D90, but the D80's are still pretty cheap.

PS: That  is a Win7 snippet.  The actual image is quite a bit sharper.
Edit: I decided to upload a little better cropped version.

Congrats! I find the increased working distance of the longer focal length macro lenses very helpful for high reproduction ratio shots. With the 55mm at 1:1 I find it very hard to light the subject without casting a shadow unless using a ring light. For lower magnification shots of say an entire PCB the shorter focal length is probably more convenient.

Note that the D70/D80/D90 won't have any exposure metering with lenses without chip (autofocus or AI-P). For that you have to step up to the D200/D300/D7000 etc.

[jpanhalt]

Thanks for the added advice, alm.  I was talking about going really cheap.  I got a D70 in great condition for $25 incl shipping, and the 55mm macro can be had for $25 to $30.  I paid about $50 for mine AI with caps and like new.  They are for a semi-permanent copy stand with known lighting.  Post-exposure adjustment gives one a large range of exposures. 

I did not spend that much just to post a few pictures here.  I live in the middle of a woods with a pond.  Wildlife, particularly the variety of birds I see is great compared to my big city life up until now. I like to document them and get help identifying.  Raptors, including golden and bald eagle, visit not infrequently.  Over the weekend, I saw the first Northern Flicker of the year.  What I posted here was just a trial shot to see how well those modern enhancements work.  I was impressed, and frankly, a little excited at the moment.

Finally managed to buy an EV.  I bought this VW ID.3, a 2.5 year old model with 30,000 miles odometer.  Wanted a fully electric car for a while and the price has come down enough to justify it - still a decent expense but the man-maths spreadsheet is doing a decent amount of work to justify it.

I found a set of slitting saws in the local bargain shop for $7, I relayed an image to a mate and he said they are $5 in a nearby store so I told him grab another set. I have a collection of larger slitting saws and arbors for the mill but not much at hand for the dremels and die grinders so these will come in handy.

I had my first AAA LSD NiMH battery go high impedance serving remote control duty, a 2009 era Maha Imedion, it fails the C9000 impedance check upon charging.

The IKEA LADDA have gone down in price on the Australian store so I bought a bunch (they jacked the price a year ag). They have much cheaper shipping for small items now only $5, it would cost me more in petrol to go there and back. Use the $15 off $50 coupon if you haven't yet, you'll find it on ozbargain.

It's a shame they discontinued the 900mAh AAA cells, you can only get the 750mAh variants now. Oh well at 2 dollarydoos per cell I'm not complaining. Fingers crossed they're still the made in Japan variant.

Hmmm.  Who do you trust?


This is pretty cool though.  Top is the RDTech PSU, bottom is the Aneng meter on the battery being charged.  I don't even need to leave the sofa.

14.45 is charge target is it not ?

[paulca]

14.45 is charge target is it not ?

Yes and no.

14.45V is the required PSU output to actually produce 14.40V across the battery.  It doesn't matter with 2 amps.  Does other times. 

Raising charger voltage to account for voltage drop and trusting the battery is an advanced technique not suitable for being left unattended.

The BM235 says the Aneng voltage is reporting 30mV high.  It adds margin, so I'm fine for this test and these conditions.

It's on 13.63V PSU to produce 13.60V (Aneng) and 13.57V BM235.

The current I was looking for was about 0.01C + 1.4A load.  It settled higher about 200mA higher, so I switched it to float.  Current didn't change much at all.  Continues at 2.3A - 1.4A load.  I'd say it's charged.

Next phase is finding where it bottoms out on quiescent, load following.

Why?  Why not?  Fun?  Toys?
