A DIY smartphone hack that's actually useful!

[@techknowdroid8144]

Hi, Matt ! After watching this video,(and drawing great inspiration from it), I went ahead, and converted a rechargeable philips electric hair trimmer/razor, into a USB powered one. The trimmer, originally had one 1.2 V AAA rechargeable cell inside, which I removed, and in its place I soldered the Voltage Step Down Board (which you have used in this video), tweaking it's output to get around 1.5 Volts. The board now drives the trimmer's motor perfectly & is fed by a portable 5 Volts, 2 Amp Mobile Power bank(Mi Power Bank 10000mAh). Thanks, once again for the inspiration!

[@chipszed]

legend. IDK why DIY Perks hasnt pinned this!

[@ScienceDiscoverer]

You could have just used few LEDs to step down the voltage. Step down board is excessive. As you did not create this board and probably have little idea how it works, you just assembled ready parts. You did Assemble It Yourself, not Do It Yourself.

[@JosephQPublic]

@@ScienceDiscoverer - I’m sure you’re fun at parties… Did he do it himself or did he hire someone to do it for him? He did it himself, thus DIY. Does DIY Perks ACTUALLY build the circuits to turn the input signal into the picture displayed for his laptop LCD screen or does he buy the pre-made components to run the screen? Is he Assemble It Yourself Perks? Stop being pedantic.

I agree

[@D00MLOORD]

The Buck-converter used in this is an MP1584. I found when making this that the MP2307 would be preferable. The MP2307 uses Synchronous Rectification and has a higher switching speed which makes it quite more efficient. It's also smaller than the MP1584. Easiest way of finding it is to search Ebay for "supper mini 3a dc-dc converter".

They're linear regulator. Not as efficient as switching regulator.

For anybody wondering, this will cost about $20 usd before the mold. The molding he uses ranges from $8-20 but you aren't using all of it on this one project. I'd say you could go cheaper by using epoxy. Maybe the paste epoxy would be a good option. Anyways, nice project. $20 isn't too bad for something original like this. Fun too.

[@SlyPearTree]

I don't need this as my phone's light is quite bright but if I did need something like this I think I would turn it into a key chain. That would be more useful than keeping it in a convenient location as it makes more sense to keep a real flashlight in that location, specially if it is not the same place where you keep your phone.

DIY Perks When researching, Google "diy Bluetooth ground loop", as this will retrieve tutorials that tackle a problem that occurs when you use a single power supply to power both the amp and Bluetooth module, the infamous ground loop, which manifests itself through a very annoying buzzing.

[@linuxmq3945]

You are amazing. Each video I am watching is a pleasure! I am not a technician and would like if you could think about something that would be useful and I have no idea if it is feasible: I live in Brisbane, Australia, the Sunny State! I drive for Uber and when waiting in the Sun, the car gets so hot that I must keep engine running for the A/C and it is very annoying. Also when leaving the car in any parking it is an oven when coming back to it. I wonder if a decent "portable" A/C could be build, such as something that would be stuck inside the windscreen with rolling solar cells accross the windscreen all the way. Kind of a roll-in roll-out design for easy storage when not used. You might think I am silly thinking about this, but it would be definitely sold fast if feasible!

[@MrArlenBrazill]

Very cool, the rubber part is terrible for heat dissipation though. A 3d printed housing and maybe even a heat sink would improve the project. Love your videos.

[@muh1h1]

Hope all phones have a current limiting feature, so noone will break his USB port trying this...

[@IIGrayfoxII]

USB ports in phones can handle 2A.

[@stehlajz]

Yes the connector itself can handle the current, but the internal phone dc-dc boost driver mostly can't. So there must be overcurrent protection to avoid damaging the otg power circuit.

[@Mixbag]

you are correct and most phones dont have protection. they dont even have over voltage protection.

[@rich1051414]

Drawing too much current over an unprotected phone will cook the traces and fuck the USB port, HOPEFULLY only breaking its OTG capability, but potentially much worse.

[@Mixbag]

micro usb is max 1.8 A however most charge no more than 1A the pcb copper tracers will defiantly burn up if that is exceeded. some 3w leds could go over that ? if it breaks the usb will no longer work once copper tracer has burnt

[@pesoen]

i would suggest using a warm led instead of a pure white, as the light is much more comfortable to the eyes(looks like a pure white in the video, i could be wrong of course) also, instead of trying to make a light yourself, you could buy a small inexpensive usb light, with a touchpad for a low price, hook it up, and bam, now you can even adjust the light on the fly :)

[@CoolTroniks]

Hey Matt, Amazing video as always, i like the way you film and explain on your videos. Even someone doesn't understand whats going on the video, but still going to continue watching. I have tried that on my friends and they continued watching till the end, questioning my after the video, still they understand 80% of it, because you explain it so well. I'd like to see how you do it. How you film, edit, voice over, etc. love to know. Regards from India.

[@saddlesore_adventures]

OR just plug usb led into OTG cable without cutting anything..... right? there are plenty on ALI.

[@slawor4]

but why

[@VinkeHD]

That's not fun

[@Rivalgamesbg]

And carry 2 cables instead of a thumb-sized device... It defeats the purpouse. You would be better off carrying a flashlight. I just didn't like how big he made it, but that way it is easier to understand by people. I would just get the usb-b connector from old data cable and short the ID and GROUND wires, then find a smaller step-down module(or shrink this one with a dremel) and a smaller led.

[@VegTutor]

this is a 3w led, not some shitty quality LED.....

[@supercables251]

You should set the voltage regulator first, setting it later will: 1. Runs the risk of damaging equipment that isn't "Smart" 2.Trains people to expect all circuits to protect themselves. 3. Blow up if the first test is on a phone charger.

[@geometric5103]

Thanks for putting the bit at the end about it warming up and the phone killing the power. As I was watching I was thinking it would get to hot and burn out the LED but you answered the question before I could ask. Cheers.

[@DIYPerks]

They're actually super easy to use - it's just a hot tip that melts the solder when touched against it. So, if you hold together the two bits that need to be connected and then touch them with the soldering iron, it all melts and joins together. See if you can borrow one from somebody first, and if you find yourself using it often consider buying a cheap one for yourself.

Why not use 2 Leds in Series instead of the voltage regulator?

[@gekkehenkie0001]

Adventist that's not how that works. 2 white leds require about 6 volt. USB provides 5 volt, so they "underperform". That's where the typical diode characteristics kick in: letting through less amps when they are "undervolted". With 2.5 volt instead of 3.2 they will use aprox 1/8 of the max current

Take possible aluminum strip, bend it half, add key ring on the middle, put some thermal paste between just polished surfaces and bolt it to leds heat sink with small machine screws. Then add suguru or what ever over it. This should also extend the usage time of the light before it over heats on point of shutting down. You can make it from steel too to make it more durable, but heat transfer is far less with steel than using aluminum.

And for iPhones you'd need a Lightning-to-USB OTG dongle. Thanks, Apple.

Wow, trying to get better performace than a flashlight without concetrating the light. lolwut

[@Shadowdarknessone]

Thank you really much. I searched so Long for something like this.

I think every YT's channel is sponsoring a company.Like WTH Isn't YT money is enough?

[@JackT9595]

Whining about an advertisement you can easily skip which is directly supporting the creator of the video you are watching. Isn't this totally free, interesting and inspiring content enough?

[@TheRealThisIsAlex]

Lotus It's my opinion.Don't judge it if you didn't agree.

[@probablydei]

You'd be surprised how much little money you get from KZbin videos. Usually around a penny for every 20 views...

[@TheRealThisIsAlex]

He made like 375£ Already!

[@JackT9595]

? My view count says 4,000 views. 4000/20 = 200. 200p = £2...

Price of all those parts from amazon inc. shipping is about 50$ For that money we can buy high quality flashlight, with 10W(1000Lm) of power so about 4 times more than that DIY crap. Also that DIY egg will die quickly because there is no cooling for the LED.

[@Arek_R.]

What heat dispenser??? Its even thermally isolated by that plastic. And no heatsink.

[@mackwood2164]

You can buy these on ebay for less than $1 dollar USD. There are two types using SMD LED's. One that is a constant brightness and one you can dim as needed. Here';s what they look like -- www.ebay.com/itm/MINI-Touch-Switch-USB-mobile-power-camping-lamp-LED-night-light-White-lamp-WF-/371741972756? -- I have a few of them and use them with a mini/micro usb OTG adapter of approximately the same size. I keep the light plugged into the usb adapter and it fits in a pocket. Much less bulky and only cost $2. Now they certainly are not 3 watt LEDs, but they are still very bright and will light up a car interior, footpath in front of you or tent quite nicely... and gently sip from the battery.

[@Arek_R.]

I have dimmable(by touch panel) usb flaslight. These are just another reason to do not build that shitty flaslight by diyperks...

[@Arek_R.]

I didnt know that it will be shit.

[@mackwood2164]

Found it. Here is the one with the touch-dimmer switch - www.ebay.com/itm/MINI-Touch-Switch-USB-mobile-power-camping-lamp-LED-night-light-White-lamp-XW9/272450283507

[@PoiSonSonic]

Happy to see you're back

[@curtisphillips2594]

Why not just use the led built in for the flash for your camera lol?

[@Edgard422]

This one is brighter

[@Baxtexx]

Did you even watch the video?

[@arshdeepthind6820]

He just said they aren’t bright enough

[@A4358h]

Nice project. Your videos are getting better with each new release. Thanks :-)

[@ilias6441]

Man you are the best!!! you might take some time to upload but it is really awesome watching your videos

[@DanSutherland]

Neat! While very portable, I'd like to make a version that extends from my phone on like a posable arm or cord to get light I can setup at any angle. I'd also add a slider to adjust brightness on the knob.

[@bilaloz4319]

Hi, just a quick tip, a single AMC7135 LED driver chip (350mA 3.3V CC CV) does the same job that Voltage Step Down Board does, and also your power led will be driven cool. Cheers !

[@dm2060]

So you're essentially surrounding the heatsink entirely in an insulating material. Smart.

[@VIDEOEPPO]

your videos are awesome. they are very different and you always give usable and workable ideas. I look up to you for making and improving my videos too. Your ideas are intelligent and your script covers almost everything. Really great!!! very inspiring

[@ziome3eg]

I hate videos where people say "You need OTG cable" when they can get a normal micro usb cable , but cool video.
