I find the real problem is how to design the front panel and how to imagine switches that can operate deep inside the boxed housing electronics. I think it becomes a mechanical engineering problem which strays from all the effort and excitement of realising the design. What's needed is that front end design handled by some computer process so that the electronic engineering is separated from it's commercial realisation but is automated if the design is taken to fruition by paying the cost.

2023 lol. I've missed a lot of older clips 😁

99k is hard to find, but resistor divider networks are very cheap and far more precise than matching ±0.1%.

Would be nice and easy to change the batteries to AA with the space I'm the jiffy. No bastard wants those useless coin batteries that cost a fortune and always go flat!

I cannot thank SMD Hall effect bidirectional current sensors pulling 50A with 150kHz bandwidth easing my life with 2kVAC isolation my GOD

It's 2022 & this video helping me a lot.
Thank u man.
U r legend 👌

Got time?

Or anyone interested in Designs in general..

As products of universal inherent quantization "computation".., default time-timing designs, ..of course the elemental mechanisms are of total importance. Functional Devices focus attention on what, how and why.

Hey @EEVblog Dave, do you do any 3D printing for your jiffy boxes?

I had bought an electronic blanket from a second hand store. It worked great I thought. It only used 8 watts. I thought "wow they have cone a long way. 8 watts nice.' then it broke a few years later. I went to buy another one to find out that I could not replace it. Every blanket I got was at least 150 watts. Devistated I didn't know what to do. I live in my RV. And to have an electric blanket that I could use for 3 or 4 days on my batteries was I wonderful thing. To use one that eats up 150 watts they would be dead in no time. 1 to 2 hours. The one I bought from the second hand store was clearly defective. But for me, it couldn't have been better. I need to find a way to bring a new blanket from 150 watts to 8 to 15 watts. So many of us love in RVs. And then there are the penny Pinchers. This would be a great thing to bring to market. Who needs 150 watts? That gets so warm it's uncomfortable. Can I just add a resister to the board somewhere to bring that down? Please help. And if you can't, can you point me in the right direction?

Does this guy talk to people like that IRL? IRL, I'd want to smack him within 90 seconds. It's mainly the way he talks – I talk to small children like that to keep their attention.
