There are DC to DC boost converters available for real cheap on eBay. These can increase the input voltage of the battery of 3.7V to a regulated 5V DC output. DC to DC boost converters are widely used in smartphones which support USB host. (eg. connecting pendrives directly via USB to the USB port of smartphones)
Love your videos. Just recently bought a 78 cb750 I got it started yesterday and let it warm up then it just turned off on me and I couldn't get it to start? Did I flood the carbs?
Been watching your videos for awhile now but never really commented. I wanted to say thanks for this one you just saved me some cash. I bought a surveyor drone from radioshack a few months ago and the battery only last about 3 to 4 minutes then another 2 hours to cool off and recharge it so you dont get to much fly time. This device has the exact same battery as my drone (well actually grandsons drone he took it over) Now I just need to find the right battery connector and he will have a few more minutes of fun threw out the day
try finding a usb backup battery, they're used to recharge mobile phones and they have a 5 volt output that you can use for powering robots, and have a charge circuit built in that's powered by usb
Good one. 5 volt battery. 4.2V is about the maximum you get from them fully charged. Those backup devices use a step-up converter to get a regulated 5V. Cheers :)
***** 5000mAh battery pack only 17$. The price to capacity is a lot better with the battery pack. www.monoprice.com/Product?c_id=108&cp_id=10831&cs_id=1083110&p_id=9283&seq=1&format=2
Cool! Do you think this could be used to power a model airplane electric motor? I haven't played with them in over 40 years, but as a kid, I remember in the 1960's they had liquid battery packs (you filled them with water from an eye dropper!) to power a little electric motor on a model plane (made of styrofoam). Of course, the idea was to reduce weight. The batteries ran for about 10 minutes and then were useless. So they sold LOTS of batteries!
Great video, thanks! Did that battery have the capacity printed on it? I'm guessing something like 200 mAh, which isn't much, but could power a very small robot.
Looks like a lipo, lithium polymer battery. I've used them for radio controlled cars before, but bigger capacity. 8.4 volt 5.5Ah and max discharge of 60C (5.5 * 60 amps) are fairly standard. Check out sites like hobbyking for lots of cheap lipo battery's and they sell chargers to.
I found the same battery in a helicopter toy. Chargeable using USB +5v power. What is the charging current/time for this little beast? Could it (over)load a computer USB port?
Hi, I've been interested in converting small electronics to usb rechargeable, so I can stop buying AA, AAA, 9V batteries. Just wondered if you could help me with a parts list. I want to convert my TV remote control, for example, from 2 AA batteries, to an internal USB rechargeable battery like a computer mouse. This lighter could be good to use. What else would I need?
For example the easiest way to make a remote rechargeable would be to buy some AA or AAA rechargeable batteries and simply take them out to recharge as needed. A more complex circuit would be to add a female micro USB board between whatever you want to power to be able to recharge the battery and you can buy many different sizes of lithium ion batteries and a battery protection circuit board to prevent over charging and a low voltage cutoff to prevent the battery from going under 2 volts. You can also add a voltmeter that display the battery charge to your project. Laptop batteries are cheap and can be used to power larger projects like I make USB rechargeable Bluetooth speakers which is fun. You can find plenty of free wiring diagrams for your project from Google search. Good luck and be careful!
Thanks for the great videos. I'm curious, did you measure the output voltage at the heating element leads? It wouldn't surprise me if there was a tiny boost converter in there somewhere to get it up to 5V at that juncture.
I would greatly doubt it. The heating element doesn't care what the voltage is, it wants current. It would be a complete waste of efficiency, and battery capacity to convert the voltage higher just to power a giant resistor. Any circuitry inside will be for battery management, and probably overcurrent protection.
Well, I see the versatility of the product, but if what you need is just the battery, I did buy about a year ago about 10 lipo batteries for my Key-chain cameras, and it was about the price of only one of those lighters.. Just a thought that is all!
wow... first of all. li-po or li-ion batteris always come in 3.7V cells with a full charging of 4.2V. you should know this. you could also measure the amps without destroying the heat element by shorting the battery using the leads, or placing the measurement and an additional load across the switch contacts. I guess you didn't bother, but it just sounded like there was no other option.
***** Dean isn't a professional electronics expert. I would do this also in another way. But he's a hacker and shares his ideas. Everybody can do this in his own way, that's okay :-)
***** Yes I understand your reasoning. My thought was measuring the current with the heater element in it would give you an Idea of what the max current draw of the battery was if it wasn't spec'ed on the battery label. LIPos can become lighters in themselves if you get them too hot.
Actually, only maybe. Trying this with sources of high current capability often end up showing more about the shunt in the meter than the source capability. Or, blow the meter fuse. Or, toast the meter shunt if it is unfused. There are texts, some otherwise pretty good, that recommend connecting an ammeter across the cell to 'measure the current' or to measure internal resistance. Not a good idea. Also note that as current draw goes up, terminal voltage drops. It isn't generally linear. Best is use a number of loads measuring terminal potential and current. I usually use power resistors, measure voltage, and calculate current, as a voltmeter will have minimum influence in circuit. Graph current vs voltage, and your mothers brother is robert.
Ok i saw these as well here in AZ... I thought about getting one but I didnt have anything to use it or re-purpose it for. *sigh* Though Curious, I do have other other things I do get in the mail, that I would love for you to actually take apart, and maybe re-purpose. Do you accept Items? Like do you have a PO Box by any chance? Things with you may enjoy, cause I cant fig out how to hack them into the projects that I have... you may though. And they are head scratchers!
Come on Dean - You need to at least find an electric motorcycle toy or something to power with this to keep your channel here on topic. Will it power a CB radio? Are you getting my drift?
Yah, I thought maybe even a simple lighter to flashlight hack would've been fun. And then it got me wondering about hacking a flashlight into a lighter... Then I realized that prolly everything can be pointlessly hacked into a lighter. Then I thought about how I could hack a crt television into a lighter. The ultimate idea came when I realized that with enough hacking, I could watch television on a lighter.
gollumondrugs bollocks!, no you can't, each battery must have its own charge supply, lithium batteries can be made into packs by joining them together either parallel or serial style, but to charge that "pack" each cell must be charged separately. joining lithiums together is not as straightforward as other batteries.
@@alynicholls3230 Bollocks! You can indeed parallel charge lithium cells with one power supply. With series charging, you would need a balance board connected across all the cells.
***** Snipping off lighter heating elements as part of your anti-smoking campaign, eh? All due respect to you, sir, for quitting, but I am never letting you sit in my car!
dale68 OK Honda update. I pulled the oil tank from it's temporary mount and drained it. I stoppered up the two holes in the crankcase so I move it off my workbench onto the floor. I'm currently brainstorming a way to build a jack that can raise it up and place it into the frame. I'm pretty busy here with last minute wedding planning (2 weeks from today) and I still have to finish up Lisa's ring! So, more Honda videos will start near the end of April or the beginning of May. :) Thanks for watching!

ya these little things are awesome, been buying them for years just for this purpose.
Was wondering if that kind of lighter can be use as a spark.
LiPo batteries are always 3.7V
And fully charged 4.2V
TREXFREAK28 Aha!
And 2 cell are always 7.4v and full charge 8.4v

BE CAREFULLY "TO PLAY LI-PO"... ..."CUZ LI-PO GO BOOM"
I use the cheapo 18650 flashlights and solder a USB 2.0. Instant 3.7 2500mh
My wife just bought one home! They’re on clearance right now. She got mine for 50 cents!

Great hack, but how many seconds battery lasted for the lighter?

With the heater and switch removed, there's enough space in that side of the case for a couple tiny motors.

Have you charged one yet, as I suspect it will charge to 4.2v as 3.7v 18650 batteries charge to 4.2v.

***** Don't you love when TH-cam experts write in their helpful comments? I tell you, us dummies would be lost without them ;>)
***** Dean isn't a professional electronics expert. I would do this also in another way. But he's a hacker and shares his ideas. Everybody can do this in his own way, that's okay :-)
Wrong. There are 3.6v AND 3.8v H.V. cells.
You should NEVER short a lithium cells terminals.... You SHOULD know this
5v buck would fit right in that case as well...
could you have measured the current with the meter across the power switch? instead of removing the heater element?
yes he could have...
Roger Lamb Yes I could have. I won't be needing the heater element so I'm not concerned about removing it.
***** NOO its a freaking gopro extra battery!!!

Awesome! that is a neat hack for a mini bot rechargeable battery.
Good video, but I really hate the idea that you destroyed the new product!
I doubt that LiPo is more than 500 mAh. Hope that's enough life for the robot
Why would you buy something like this to hack it instead of simply buying a simple LiPo that will fit your needs and will be cheaper/same price ?
Viproz Cause nice case and has charge circuit in place

Is there a way to charge 2 batteries using 1 USB connector?
extremestick You can charge as many as you like as long but every time you double the batteries, you double the charge time.

Usb rechargeable soldering iron?
Wouldn't last but a few minutes at most
What wire dude
you should jsut start smoking and then you could use it as it was intended...
CR2504life I quit smoking 19 years ago. Not about to start again. :)
***** Snipping off lighter heating elements as part of your anti-smoking campaign, eh? All due respect to you, sir, for quitting, but I am never letting you sit in my car!
try to smoke a bowl with that lighter lol
Or not...
Hey Can you hack it and make it phone charger and try to recharge the battery whit solar panel
Cool hack
I feel the need, the need for HONDA UPDATE!! ;o)
