I was so intrigued by the super-minimalist digital panel indicators that I decided to reverse engineer one and try to work out what the chip is.
By popular request I also pop some hydrogen and oxygen mix generated by the water hydrogenator.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

Makes your sex life go with a bang
The test of the explosion proof properties of a government standard condom was well worth the wait 😶🌫🧨🧨🎆🎇
What use is the 51 ohm resistor ? According to my ltspice simulation (i replaced the AC with a 330ohm load resistor, drawing 14mA) the 51 ohm resistor only has 53mA peak AC current going through it (so 2.7V peak AC). SO for the life of me, i cannont understand why it is there, except separating grid neutral from dc ground. Please enlight me, thanks in advance
Do You see a way to read the values with an Arduino or an ESP8266? Or any place to investigate further?
Oh extra credit sequel to the hydrogen water bottle how awesome 😎. That should have been a video on its own. Maybe make a short with it?
Q : "Why Didn't You Light The Hydrogen, Clive? That's Not Like You?" C : "Well It Wasn't Because The Want Of Trying, I Didn't Have Enough Hydrogen" "However, I Have A Plan ……"
I wasn't disappointed. It had the appropriate apparatus for such an experiment and worked superbly well.
Ah the Hindenburg condom.
you can explain how to measure mah with a battery and how calculate.
greetings from the Netherlands
I just got one of these, its square and has led chips on the pcb to make up the segments, very neat.
💣💥 brilliant. …
I was intrigued by the product too. Thanks for persisting with the tear down. I dont get how they can drive these LEDs with without standard transistors and resistors.
Is it possible to give more accuracy to this circuit?
Here in Brazil we have what they call the "new standard" outlets in 10A and 20A variants. The 20A has fatter pins so that it can`t fit into a 10A socket but t'other way around is OK. This is all fine and dandy, but we also have two voltage levels – what everyone calls 110 (actually 127) and 220, frequently both in the same premises using two phases. The connections for these are not physically distinguished. Sigh.
So, to lessen the chance of mishaps I decided to add these little indicators to a couple of extension leads. This works a treat but a couple of things arise with the ones I bought. I got 3 each red green and yellow. The reds and greens are fine but the yellows are reading significantly, something like 5%, under voltage. Maybe a duff batch as Clive's yellows appear to be fine.
The other thing, and it leads on from that, is that orientation can be misleading. One of mine reads 122V when fed from a 127V supply. See that upside down and it shows 221 which is what you'd expect across both phases. Worse still that applies in reverse – 220V supply reading as 221 will look like 122 when upside down. Probably not a problem on a fixed panel but something to be considered on a floating extension socket.
you could hook it up to a pic programmer and see if it identifies itself. you never know maybe code protection isnt set
Well it's good to know that you use condoms with your fun Clive! lol
I see what you mean about it not being able to run a car on lol
Little fire just to the tip and it went off with a bang!
