Multimeter chip is probably angled to accommodate whatever soldering process they were using (wave soldering?). It looks like having it at an angle made it harder to route, not easier.
-
My Philips PM2518X looks almost identical to the PM2718 one Dave got, only held together by some tape.
The case is really brittle. Because of the heavy batteries it will shatter if you drop the multimeter.
Except from that it is a really good DMM having a 100kHz true rms ac input.
Note the reversed polarity diode tester connection: The common wire outputs the positive voltage when testing diodes!

Sending a ton of German tools from Baltimore. ;D
But you really didn't know Knipex? Must be one of the best manufacturers for high-end tools in the world: very pricey but worth every penny. Wondering what vendor you're using...
The wrench is called a monkey wrench in English I believe, here in Germany we call it what you would translate into "Frenchmen", no idea why... ;)
-
If you just want to easily generate some (haven't tested how fast it would go actually) SPI/I2C signals you can use a Teensy++ 2.0 board (or similar using an AT90USB646, AT90USB647, AT90USB1286, AT90USB1287) with this software programmed onto it: https://tty1.net/userial/index_en.html . When connected to USB that will present a serial device to which you can easily post ASCII sequences defining the signal you want to send, or use a terminal program to read out sensor data.
I'm currently building a new board that does the same but with built-in level conversion and a few more gimmicks... ;)

I have always known it as "Wasserpumpenzange" which loosely translates to "water pump wrench".

I knew the small version Dave got under the name "Wasserpumpenzange" (water pump wrench).
Its larger brother I knew under the name "Frenchmen".

In spanish that's a "pico de loro". A monkey wrench is another kind of wrench, a "grifa" in spanish.

Why did you treat that poor philips so badly?
-
What's with the ever increasing current off that PV? At that rate it may very well achieve overunity!

And then there's the "llave inglesa". :popcorn:

It obvious has a lot of name, in our country we use:
vandpumpetang: Water pump wrench
Polygrip tang: Multi grip pliers (It looks like this is the normal name in Sweden).
The "Monkey wrench" has never caught on.
I do not really like this type of pliers (I do use them), they are way to easy to get pinched in.

The lamp was probably a Compact fluorescent lamp. Depending on the circuit they increase the light intensity after some warm-up time. Some do this not linear: I have some that start at about 80% (guesstimation, not measured) and stay at this level for about a minute or two and then they increase to the 100% within about 10 seconds.
-
The number on the chip in the Philips looks like OQ0067 to me, not 000067.

True dat.

I was planning to read an improving book this evening, but now I have to watch all those German Tool Reviews videos. ;D

Well, that's improving - isn't it?
-
Well, will save some videos for tomorrow, and go read my improving book ("Behave" by Robert Sapolsky, came highly recommended).
And Dave released 3 new videos while I was watching the tools ones. Book can't get a break. ;)

organic flexible solar cell phone charger may need upscaling IMO. as the design is brilliant :-+ but the solar surface area looks too small . for fast emergency phone re-chargeing. if the multiple phones need charging in an emergency. >:(
if say flexible solar is designed to be the size of a folded umbrella when closed, & when it is open, the flexible solar size of a hammock with end bar & tie strings. one end around a tree other on the ground.
HP 48G destructive calculator teardown is not necessarily the end of it
try some modding /repackaging of the calculator pcb and adding custom-made button switches in a new enclosure. :-/O
have you seen modding video game console enclosures. ;D
new box cutters :-+
Dave have you considered a robot knife arm to help with opening your mail. Mailbag is a repetitive process, so put some of your engineering skills to work.
add same automation to your job. 8) you never know, the airport security industry, may just pay for a working robot prototype. ;)
all suggestions, tongue in cheek !
Good show Dave

No one really calls those monkey wrenches or tongue and groove, everyone calls them Cobras(like they're named) the lower end model is the Alligator...Knipex does sell a tongue and groove plier, so otherwise that would be quite confusing.
I'm surprised none of you got on Dave about the pronunciation of Knipex and Wiha.
-
They tend to be called "Multi-grips" here in Australia.
.... and let's not get into Dave's pronunciation of things. I cringe sometimes - but that's just Dave.
-

Nah, that's a lost cause.
(and I bet Dave can come up with some Australian names that you can't pronounce)

In the 60s when I worked at a NASA ground station, the Americans called them channel locks.

Channel Lock is the USA brand.

After the SD-Card massage video, I wish the mailing-costs to Australia are lower.
I would have sent him a decent set of self made German-style cross peen hammer.
(0.5Kg, 1Kg, 5Kg, 10Kg and 25Kg )
With the wimpy excuse of an hammer Dave used, he is gone to hurt himself.
Is this one if this decorative hammers with multiple screwdriver in its handle?
