Surprise eBay buy time!

Just bought this for 28 euros delivered. The seller was advertising it as DC Amplifier. The vernier looks like some scope Y amplifier and the sticker also seems to point to that, but then why doesn't it use a BNC jack in the input??

The only reason I bought it is for the 0.5mV/cm range. If it is actually a DC Amplifier it will be interesting to see how they handle that.

Anyone knows what this box actually is?

I understand then that it is really DC to low frequency?

Oh yes, my nibbler's gone walkabout...

Yeah ... my nibbler went walkabout too.  Haven't seen it in over 20 years.   

(Haven't needed it for 25  )

What is it with nibblers going AWOL, you need to feed them once in a while

Probably yes. As long as you don't find an ID, it's guesswork and testing.

Am currently refreshing the JLCpcb site hourly to watch progress on my two latest constructions.  Also have placed a Mouser order. So, it's waiting times here.

This time is filled up with shopping for Du Pont connector clone kits. My layout is using them frequently.

To make that time pass (and it feels like it's slower than usual!), I'm whipping up a Bœuf Bourgignon. Soon spud peeling time.

Oh just woke up checking TEA and what do I see, another mega high res cooking picture.... I will forgive you if once you are done, you do it all over again, to make me some blanquette de veau instead.
If you send it with your private jet, it should still be warm by the time it arrives.  Send me message before landing, so I have time to cook the potatoes and rice to go with it.

Thanks in advance.

I'm currently eating one too many bacon, egg & cheese breakfast tacos, washed down with too much coffee that has too much heavy cream in it and so much sweetener the coffee itself may get cancer.

All cooked by someone who loves me far more than I deserve. 

Yumm.

I've never tried blanquette de veau, had to look it up. Sounds tasty. I'll make one, or a bœuf bourgignon, at my discretion, for you if I pass St. Nazaire.  There's a slight lacking in the private jet department.

In the mean time, I added what makes a BB a BB, the small ognions, the shrooms, and the pôrk, and then got rave reviews on my cooking.

Edit: Passing St. Nazaire is not an empty threat. Though I've read that Lorient has the better u-boat pens, so that might win out. Further, Saint-Nazaire is en route to Saumur, which also is on the bucket list.

Looks nice,  I think I will make you my cooking slave if you come around here. I will attach you to a pole in the kitchen with a heavy duty chain so you can't escape, and you will cook for me for the rest of your life. You will also of course be in charge of sorting out all my computer /IT stuff, network etc, because I couldn't do it to save my life.

I don't like BB too much, but I love blanquette de veau. By the loos of it, I guess you would cook it in just the same way anyway.. should take you no effort to adapt to it.

Don't think that's the way it works...

Boring Mundane Everyday Print #288: Keyboard Tilt Feet   



Latest 3DP abuse was for this old HP keyboard stuck in the bottom of a bin forever since one of the rear tilt legs broke. Well, right now it's the only standard keyboard I have to throw on my laptop in the living room; so its time has finally come.

Took me a good 30 minutes to draw this one up; I had to figure out how to do those compound fillets.

As always; for those who care, full details and 3DP nerd-stats are over in the 3DP Thread.

I thought you were on a diet ?? Or has this changed 3 days ago when you decided you were not a dragon anymore ?

Everything in my breakfast tacos is on my Hard Keto diet. The tortillas are lo-carb/hi-fiber, 4 grams net each. 1 gram for the heavy cream, 2 grams for the eggs. I still have 4-9 grams left for the rest of the day. 780 calories total, of 1500 daily.

Sometimes I splurge on breakfast, sometimes I save my carbs/cals for dinner.  Today I'll have to make it up with stir-fry veggies and chicken to keep the cal count down. I'll make a pot of rice to go along with for the wife & kids.

A warning to anyone out there with an Creality Ender 3 3D Printer: Don't upgrade the hardware from the old 8 Bit board to the newer 32Bit 4.2.x boards. The hardware is fine and quieter (as the loudly claim), but the firmware is just broken. Missing features, non-working commands (and not trivial stuff either, basics such as filament loading and mid-print colour change aren't implemented or not working). I'll be spending the evening downgrading my Ender 3 Pro hardware.

Check of the HV in the 2nd Type 547. Determination is it's HV transformer is toast too.

Just have to monitor one point to confirm. The pin 8 (Grid) of V800.




Started out at +76V, soon climbed to +90V which is where it should more or less stabilize.




It climbed to +95V/+96V and stayed there for quite a while and I was beginning to think this one was OK.



Wishful thinking. Suddenly started climbing noticeably. I stopped it at +110V. NFG.



So I removed this HV assembly. It is going to make a trip to Germany to get repaired.

Nah, when I want people to come, all I have to do is tell them I am OK to look at their old electronic junk they wanted me to fix (for free of course ! )

Works every single time ! People are so predictable !

Is there no open source firmware. 32bit marlin?
There is a promising config for it I'd say: "Configurations-release-2.0.9.3.zip\Configurations-release-2.0.9.3\config\examples\Creality\Ender-3\CrealityV422"
There is also one for V427. Try that before changing hardware says me!
Edit#2: And it's not as hard as they make it look. I've done similar Marlin installs before, it's really not too bad!

Oh, Med, what Tek 5-series plug-in were you after? There's a bunch on ebay in Germany today.

Have you considered not using the heavy cream?

I prefer sour cream, creme fraiche, or plain yogurt, all of which have more taste so you can use less.

Another hp 5216A arrived earlier this week, advertised as defective, on inspection I found the 150mA mains fuse blown. A replacement with a slightly lower value fuse resulted in one of the displays lighting very briefly, yep blew again.

Today I pulled the power supply board & started checking for shorted components, quickly found one of the pair of zeners for the +/-6V supplies was shorted.




Manual states it's a 6.04V at 2%, no other info apart from the custom part no. The other zener diode measured in at 6.01V at 5mA.


Then I went through the drawer of 6.2V 1.3W zeners, to find a suitable pair to replace them both, I found a pair that matched at just under 6V, 10mA each. After fitting them I checked this part of the supply to verify it was working before refitting it.



Back in it went, along with another fuse, the lamp limiter was used and the 100W lamp left in it glowed brightly, followed by the fuse blowing again. Bugger still something wrong with it, I removed the power supply board again and changed the lamp for a 15W one & fitted another fuse, again the lamp was bright.

At this point I had a look at the power rating in manual, it gives a maximum of 20W.
No 25W lamps were in the box for the lamp limiter, so I fitted a 40W, this also lit brightly. At this point it's looking like I have another counter with a buggered transformer. I will put the 15W lamp back tomorrow & check the outputs from the secondary windings tomorrow, run out of time tonight.

Context dear boy, you're advocating using those in coffee. That registers somewhere between "Yuck!" and "Die, coffee adulterating philistine!". Mind you, so does adding cream to coffee in my book, but that's a matter of taste, whereas putting yogurt in it would fit more into the category of "terminal lack of taste".

I'm currently eating one too many bacon, egg & cheese breakfast tacos, washed down with too much coffee that has too much heavy cream in it and so much sweetener the coffee itself may get cancer.

I knew you got me, C. I'll happily be a coffee adulterer, as long as its heavy cream & sweetener.

The heavy cream is for the low-carb aspect. Milk has too much sugar in it; pure cream has zero carbs and I can do a tablespoon or two and get the flavor I like. Over here it is nigh-impossible to get really pure cream that isn't contaminated with carrageenan, so I have to allow half a gram or so per serving to stay on the right side of the Keto.

Hmmmm... My CR6-SE has that board in it; seems to do everything it's supposed to, tho I don't have a multi-color head on it.

I'm not too comfortable with PlatformIO, so haven't been poking around in its firmware yet, tho I really would like to repurpose the I/O channel they used for a fucking blue LED on the work to run the heat-brake fan.
