At 13:56 he is reluctant to buy a handheld 50/60Hz strobe light for US$75 and finds a similar "homemade flashy box thing" for £20Question is what components are in the $75 version compared with the £20 DIY version?
A microcontroller, clock crystal, LEDs with driver circuitry?

[Bigclivedotcom] busts a myth that those cheap Ebay/Aliexpress TP4056 lithium polymer battery charger modules will end up overcharging your battery if you keep them in circuit powering a load (e.g. a string of LED fairy lights)

This whole incident reminds me of this vintage 1979 episode of "Project U.F.O." - "The Whitman Tower Incident" (S2E12)
https://youtu.be/IvByc4lNH54?t=38m10s
If you don't want the watch the whole poorly recorded episode you can skip to 38:10 for the explanationApparently the Project #UFO TV series was based on actual Project BLUE BOOK casefiles.

I spent the weekend cutting copper slug tape into thin strips, sticking them to a piece of cardboard at regular 1.2mm (not 1.27mm) spacing, coating with solder, and carefully aligning them with the zebra connector for a LCD display of a broken DT-830B multimeter clone
I suppose an alternative would have been to order several PCBs each with a slightly different offset for the zebra connector, and then throw away the ones that were misaligned

My #genuary22 contribution was inspired by the #shadow artistry of Shigeo Fukada. His "Lunch With a Helmet On" must be seen to be believed

This reminds me of my own experiments with making #LED decorations powered wirelessly
From my #TwitterArchive
Inductor, diode, 1000 uF electrolytic capacitor, TL431A for voltage regulation and a meteor shower LED #decoration which draws all its power from a Qi #wireless charger

This #Poundland #screwdriver set is useless for removing these hex screws that fasten the metal housing for a COB LED I found on the street. Did this get snapped off from a vehicle or a flashing street sign?
The hex-star bits don't fit the screws properly and the metal is too soft so they just get chewed up
The PCB has 3 LEDs on each side. All 6 seem to be working. 3 in series, both sides in parallel. Total forward voltage of about 7.6V

Vapers on Reddit noticed the blatant #shrinkflation in Elfbar #vapePens and Lost Mary disposable #vapes months ago
I wonder if this why I have been finding more discarded Crystal brands than Elfbars recently
-
Whether or not these disposable #vape devices get banned, the astonishing level of #shrinkflation that is bordering on scam territory, should be sufficient reason to stop buying these single-use #VapePens
The 550mAh #lithiumPolymer #battery (date code 221101) was found in a discarded Elfbar 600 from earlier this year.
The 360mAh battery (date code 230417) from an Elfbar 600 I picked up from the side of a road today

I've been finding many more Crystal brand disposable #VapePens discarded on the street this year. They are becoming nearly as frequent as those ELFBAR 600 #vape devices that I found so often last year. #litter #waste #BatteryHarvesting #ecigarette

My video on how the various #OpAmp circuits were combined to map RGB rainbow colors to a single 10K potentiometer

Using 7 dual #opamps (LM358) to generate PWM signals for driving a non-addressable RGB LED strip so that only one linear potentiometer is needed to sweep through the colours of the #rainbowFlag
Project inspired by

in which @blitzcitydiy used a microcontroller to map a potentiometer to the range of hues -
Three potentiometers control the duty cycle for pulse width modulation of the three colour channels of an RGB LED strip (non-addressable). The PWM signal is generated by #opamps (#LM358) configured as an oscillator and 3 comparators. An NPN transistor sinks the current for each of the LED colours.

So glad I watched Bigclive's teardown video for the new Elfbar 600V2

Haven't seen a single-use #vape device in this form factor before. Found discarded in the grass along the side of a public footpath
Internal #LithiumPolymer battery is rechargeable via USB-C but the tank is not refillable. Still has a voltage of 3.7V
I wonder how many times it was recharged before becoming street #litter -
Lipoly battery in this crushed Packman branded vape device was fully charged when I found it in a carpark last night
There is a USB-C port for recharging. The atomizer tank was already missing so cannot tell if it was intended to be refillable. Judging from the vape brand's website it was probably disposable

Likewise vapers wouldn't want to put into their mouths something that was touched by a random stranger
https://www.joe.co.uk/news/people-vow-never-to-buy-disposable-vapes-again-after-seeing-how-theyre-created-399966We need a video of a worker at one of these #vapepen factories wiping his butt with a disposable #ecigarette to go viral

Found all these disposable #Vape devices by just walking into town and back today. Passed by a few that were little more than shattered remains in the road. Even the run overs might still have salvageable electronics -- the pressure sensor can be repurposed as a capacitive touch switch
At this rate I'll easily exceed the number I found last year.

And now Becky Stern has joined the disposable #vape #lithiumPolymer #battery salvaging club

Look at how small the #lithiumPolymer battery is in relation to the size of the disposable #VapePen
1.48Wh (400mAh 3.7V)Might be useful should I need to replace another battery in some wireless device, assuming I can recharge it - voltage is reading very low 1.2V
