Your passion for quality capacitors is probably only matched by ur passion for multimeters. Best gift ever those caps.

[profpep]

The Screws are where the bank programs the account info into the device. There is a baseplate adapter. Most likely a serial interface like SPI

[rocketmanprojects]

Those AVX super capacitors are some very nice ones. They are low ESR and can supply some pretty high current.
That 400F cap would most likely be able to spot weld stuff, it's rated for 173 amps peak!

It's probably a good thing the flashlight kit comes already soldered. The WS2812 LEDs are extremely easy to kill when soldering, they are not exactly beginner friendly.

What's better than an EEVBlog video? An EEVBlog video with a notification halfway through that bigclivedotcom has uploaded a new video. I wonder if I'll get a notification about an AvE video halfway through Big Clive's?!

Abnormally good times. Nice job Dave. Thanks.

Since the release of Crocodile Dundee every Australian gets one of these Knifes as a passport replacement

Dave, Innova also make OBDII reader, available in car stores, like Canadian Tire. They are consumer grade devices, not pro.

Mailbag is still the best and most entertaining part of your channel. By the way I also like your teardown videos of old computer stuff. Maybe you should add the strip to your next meter, it is really the best invention ever happened to a multimeter. Thanks for your videos, I started watching them 4 years ago.
You make me interested again building electronic stuff, I did not do anything for about 10 years with my trusty old Weller soldering station.
Now I'm back with electronic with my own little channel just hit the number of 320 subscribers, but this is already great that people like to watch me.

the probe tip idea is very interesting.

[MikeBramm]

It's kind of difficult to see clearly, but if you look in the screw holes at IN-R and IN-L (at about 30:57), it looks like those holes are not fully plated through. Could that be a 4-layer board with the outer layers being plated and layers 2 and 3 missing in those areas, allowing the top and bottom layers to be squeezed together when the screws are tightened (and opening a circuit when the screws are loosened or removed)? Also, I think you need to make a Kick Starter with a couple of those little joysticks on it, kind of like a new type of fidget toy. Keep up the good work.

"A multimeter strapped on the back of your hand" xD That was the best laugh I've had in a while.

[kruleworld]

We use AMX controllers at work. they use them to choose what input (computer, dvd, camera) displays on what device (dual tv, projector, monitor) etc.

[randycarter]

The screws are the programing interface. Before it's packaged it is set on a jig to load the final settings/program. No connector required. Case doesn't have to be opened after assembly.

[goneutt]

Using the screws as a programming interface is somewhat brilliant.

[embeddedgirl]

AMX is a building automation and audio visual automation interface. You can write your own custom firmware if need be, but generally are installed in situations such as conference rooms, lecture halls, etc.

The designer was so impressed holding his strap-on in his hand he HAD to seek a patent for it..

[dashcamandy]

As someone that works on both electronics and cars, I can see no reasonable application for a strap-on meter. Innova makes a great deal of automotive repair products like OBD-II scanners and the like.

[Tbn]

I considered buying an Open Pandora back in the day, but despite their efforts to reduce cost it was pretty damn expensive

[ophello]

I thought you proved that mailbag WASN’T everyone’s favorite segment.

Hey, I have *THE* perfect idea for a multimeter mount for team of an industrial electrician and a helper: The multimeter gets mounted on the back of a hard hat of the helper, and a footswitch for sequentially switching through its modes goes into the rear pocket of his trousers. Like that, the electrician will at all times have his hands free to twiddle knobs, make notes on a clipboard or similar or hold a mug of coffee while the helper keeps the probes where they have to be! ^^)
Where do I have to call to get this remarkable design idea patented?
