Ahh it's been a while since we got a classic Matthias Machine Modification!
Matthias, great video but as someone who works on lots of home brew projects with these batteries I think there’s one thing you need to mention. All lithium ion batteries should have a low voltage cutoff, as a Li-Ion battery drained to zero is essentially junked. Dewalt handles low voltage cutoff in the tool, not in the battery, so if you forget your light and leave it on all night you’ve effectively junked your battery. I’d put a note in the comments or somewhere to be sure people know this, I’d hate for people trying to save money on their light to junk $75 batteries instead.
Sounds like an important callout! Is that not already integrated into the battery itself? If not, how would someone add this?
@@derekroetzel done lithium ion batteries do, DeWalt chose to include that in the tool and not the battery. You'd need a circuit to do that and put it inline. I don't have one in particular I use, but I imagine digikey and them have premade boards for that
if Dewalt changes the design of those protectors we'll all know why.
DeWalt: Hey Matthias, we'd love to send you some products for review. Here you go.
Matthias: *builds frankenlight*
DeWalt: 😦
Thats why I use Makita. The lxt system is more than 12 years old now and they still make a lot of tools for the system (275+ tools).
@@heimdall4148 Dewalt is better.
Everything you make looks like furniture. Rounded corners, counter-sunk screws, ... I’m surprised you didn’t stain it as well.
Well done. Thanks.
stain? you mean green paint? ;)
@@poptartmcjelly7054 It's called Matthias green®
Looks like a great project for someone with a 3d printer
but first you have to build the 3d printer. that's how it works on this channel
And you have to build it out of wood from a "dump find" chest of drawers, some lego motors and an old curling iron.
You read my mind.
...or AvE's HAAS
some free battery adapter models, if you have 3D printer

You're an absolute genius. I'm finding it difficult to stop watching your videos. Unbelievable.
And as a plus you can get a variety of MR16 bulbs, with different color temperature and wide angle or focus lens, and even a party mode colour changing 😂
Be careful! DeWalt XR battery packs do not have undervolt protection. A bulb like this will suck the battery dry to the point it might not take a charge.
if that ever happens all you have to do is take a good battery and jump the dead battery in parallel for a few minutes, and it will bring the dead battery back to life..... this is coming from someone that has been working with all types of lithium batteries for over 20yrs...
Are you think that the first lamp has same protect?
@@darkfrei2 the DeWalt lamp has protection, yes.
@@OliWarner So you can take the body of this lamp and set new LED to it.
Since the bulb uses a voltage regulator this won't be a problem, as the power should be cut off at a certain voltage
Very nice video Matthias! The simplicity of this is genuis
Holy hell. I already have all this stuff right now. I'm going to make one today
This is one of those "why didn't I think of that" moments. Sir you are a bloody genius. I love your woodworking projects but these are fascinating. Tar muchly (English expression) translated into, thank you very much.
Pretty cool quick and dirty project!
I bought off eBay an adapter that has two wires and fits dewalt 20v batteries for 12 dollars. I then connected it to a 15 dollar led off road light. Works just great.
Not bad, however you're looking at $27 for a light.
You can these lights for like $5 or a COB array of 10-25W for same price.
@@boots7859 that adapter is very flexible though, easilly can be adapted to work with anything. Worth getting.
Careful if your circuit doesn't include a way to protect the battery from over-discharging. Every DeWalt tool prevents you draining the battery to where you cannot charge it. Would hate to see you scrap $100+ of batteries!
@Ralph Macchiato it doesn't always work. Some Lithium-ion cells can be irreversibly damaged (e.g. swelled) by uncontrolled discharging. Had this happen to some good RC batteries.
As always, great video Matt!
I remember some time ago I ran out of battery on both my cellphone and my portable speaker
I realized my cordless Makita drill was in the car so I hooked the battery to an old cig-lighter socket
plugged my car USB adapter and saved the day lol
it was Sunday morning on the beach, we could listen to music again and my friends were amazed!
I got tired of trying to improvise multimeter probes to measure the voltage of my battery, so I made a small voltage meter: 2 standard brass male terminal connectors that slide in to the contacts, and a $1 voltage meter. Works perfect.
It's for the small Li-ion batteries for a small Bosch impact driver. The battery lasts a frustratingly short amount of time.
I glued it all to a piece of wood that I carved, so one side sticks out and doesn't allow you to plug it in backwards and possibly ruin the meter. Hope this makes sense. Just thought I'd share the simple idea for using terminal connectors.
Just watch out, the battery might not have over discharge protection. Not sure about the dewalt with the whole flex volt thing but with my Milwaukee batteries the terminals are connected directly to the cells (and the protection is in the tool). That said, pretty neat, have been meaning to do a custom work light for a while.
This is true for DeWalt batteries too; protection is in the tool, not in the battery. The worse part is that there is no short circuit protection. Mathias should have put a compact fuse on one of the wires IMO.
@@mrvelleful they are pretty small wires...
Yeah, this would be a really cheap way to kill a very expensive battery.
It also needs a switch, because fitting the thing into those tiny holes in the dark. And stepping on nails sticking out of a board.
I stopped pooping when I got the notification and went in to the living room to watch this from a bigger screen. I don't regret anything.
Great idea, i've just made one using 3d printed parts and makita battery. Hope that over time the led bulb will not get harmed by increased voltage
And you thought you couldn't use a 3D Printer. Perfect project for that. Possibilities to improve on this design is limitless.
Better than all the other DIY videos people make
Next video: a drill battery light that follows you around
And shoots yogurt caps at you
@@MightyGiant Excellent idea
@@MightyGiant cool, maybe a mobile robot that hunts you down
And keeps your coffee warm
and shoots Lego, and catches mice, and ...
Wow! Awesome simple build. Thanks matthias.
Well, if you have the tools, and the fiddle powers, you can make anything out of wood, even a band saw frame! *laughs* I do love watching you "prototype" it's very thoughtful. Your process from stage to stage, dealing with each concern that arrises, as a natural progression without becoming frustrated. there's a never ending supply of things you could build. I just hope your hands can keep up with your mind.
When you said that it was going to be basic, I was expecting it to have an Arduino for tracking purposes.
Yeah these LED bulbs also work well to convert old 18v flashlights with incandescent bulbs to LED. The original bulbs draws 10 watts and puts out 60 lumens whereas a 7 watt LED 12V Track Light puts out 500 lumens...All you have to do is rip out the old reflector and what have you.Then mount the bulb in the plastic lens securing it with screws or some small machine screws and nuts. To connect the power you can normally solder the new bulb directly to the wires for the old bulb socket....One important thing though, you need to drill some holes in the flashlight housing around the new LED bulb for ventilation or it will overheat and burnout after about 20 minutes of continuous use.
Its like you read my mind! I was just looking at ways how to add a light to my snow blower and use a drill battery to power it. Thanks!
This is crying out to be combined with the Pi/stepper motor set up you used with the infra-red heater. Ceiling mounted, and the light then follows you in the workshop. Set up a few with a perimeter setting on Pi camera so as you move around the workshop one turns on as another turns off 👍
This is ingenious! Will be trying myself asap. Thanks once again Matthias
I really wish Dewalt would make a product more like your design. I like that it's super compact. It could have some kind of simple tilt to it, but mostly just shining it into the area you're working will do more than enough because it's SO DAMN BRIGHT.
Cool project - good work :D
Great video and idea!
Would you mind sharing a link to, or more specs on those bulbs?
I find that spade terminals slip in to battery connections quite well. Lots of uses.
Cool project dude .. I like it very much. Thank you for sharing.
Hi, Matthias. Ein Schwabe bleibt ein Schwabe, egal wo er wohnt....👍
Gute Arbeit, wie immer. Deine Drechselvorrichtung für Keilriemenscheiben und dein Zahnrad aus Holz ist ständig im Einsatz. Du bist mit verantwortlich, dass ich endlich meinen Spass im Keller habe. Gruß aus Baden
That's what I waited for... Great work Matthias!
Usefulness does not have to be expensive. I Like it!
Great idea, I would add a rubber band to hold the unit to the battery, if the nails elevate out of place they could make a little spark!
Brilliant as usual . Thinking outside the box . Thanks
Well, it certainly isn't *dull*.
I’ve been watching your videos and enjoying them for a few years now. I’m somebody else told this before but you should really discover 3d printing.
It is surprisingly bright!
Most useful cordless tools I have. I just used those LED spotlights you can buy from china, intended for vehicle installation, and the Makita USB adapter for a battery interface. The cordless soldering station using a JBC iron comes a close second. I don't know why makita doesn't make those, or in the case of lights only crappy ones.
awesome video as always
Hi Matthias!
I only have Makita batteries around and I love to use their heated jacket adapter for projects like this. They even provide 5V for small electronics projects on the go. Just as a hint for future Mouse traps or such.
Regards,
Etna.
Matthias, When I first glanced at the thumbnail, I thought you had motorized and put tracks on the light to remote control it to light dark corners of your realm. Perhaps with a camera also. But this is still a good cheap way to make a portable strong battery. Thanks!
A thick rubber band could hold the two parts together, if you use it at a strange angle for example.
Matthias is BACK............awesome sauce!
Big companies don’t want you to know this one weird trick.
Thanks I made with my Radley drill coz it was broken I only remove the motor and it's perfect
Love this and it's the same brand I use, so thanks for the info!!
Yes I could have looked it up, but now I don't have to :D
Finally a video that doesn't involve Lego.
I have some similar LED bulbs that I bought to use the optics for another project. Now I'm thinking about using them to light my bedroom from my solar setup.
You could attach the LED assembly directly to the plastic protector with Sugru, and you can also use Sugru to insulate the wires (and wire a simple switch into the circuit). No need for scraps of wood.
This is an awesome video, keep it up! Thank you for still putting out great content!
It's possible that the regulator in the bulb provides constant current rather than constant power. An LED component provides steady light output when it is provided a constant current from a regulator. Of course this makes little difference unless you're selecting a regulator for the LEDs and not using a bulb with a built-in regulator.
the need of something sharpens the idea of the make ! cool:)
Great video..
my favorite channel.. nice Matthias Wandel👍
Really simple and cool! Tom Sachs makes homemade attachements for drill batteries, it's really too bad they're so expensive because you can do a lot with them (the DeWalt/Makita/etc batteries)
He's back! I love this video so much!
thats a useful little light, nice job.
Very nice gadget, thanks to share.
I used a burned out emergency light and did similar for a makita pack.
Great Build! I have been wanting sth like this for my batteries quite some time and was thinking about 3d printing the lamp case... your video made me look on thingiverse and there was already a thing, just as i want it. Perfect! NOW i am building it👍🏼Thank you for inspiration and motivating me!
Always a treat! Thanks man
I am not sure DEWALT will be pleased with this video xD
They're going to stop making those convenient red holders.
Simple and easy. If i will make one i will design it in a way where you will have the light telescopic adjusted.
Also been brooding on this idea for 14 days, I thought to make a clip with 3d printing (but I don't have one). Using these lamps is brilliant. Wonder if you can't make a clip with a plastic agent such as wood filler. Make one with a tripod
Do the DeWalt batteries have internal battery management? Will they cut off when the voltage drops to a set point to avoid over-discharge? I've heard some brands will do it automatically, and some leave it up to the tool in question to avoid damaging the Li-ion cells.
I kind of assumed that circuitry is in the battery. It already has the 20/60 volt switching capability.
Lithium cells should be protected on cell level, leaving it up to the tool for battery pack management is grossly incompetent.
I don't know about 20/60V model, but previous 20V model had outputs directly soldered to cells - no protection.
@@tomass9235 Yikes, that's an horrible safety practice for Lithium cells, to rely on the charger and load for protection.
@@sparqqling Positive side is that you can refurbish battery with just replacing cells - no fancy electronics to object the change. Fun fact - I have 2 dewalt 4.0Ah batteries and after long use on both the 5th. cell couple had much more wear than others. Dewalt DCB105 charger refused to charge it. 5th pair had much less capacity left compared to other cell pairs. Still not sure if this is chargers fault or coincidence.
Nifty! 👍.. I'd swap out them nails for some bolts with wing nuts, and apply a toggle switch to the wiring, as well as a pivoting wooden base for angling the light! Sorry..lol.. My mind just went crazy with ideas! 😁👍
Very interesting solution. As always!
they already make those for just about any situation even converting dewalt to rigid, rigid to craftsman, so on and so on. they are sold on EBAY
Is the low voltage cutoff built into the battery or into the tool? It'd be a shame to wreck a battery by running it too flat, but it won't be an issue if the LVC is built in.
Nice. Thanks!
Really interesting concept! Think this has inspired me to try something like this! Good work Sir!!
Nice project! Just bought 160 dollar rigid led work light with 50 Bosch tripod. Nice setup but 230$ like yours better!
Perfect!
You can buy the spare part battery terminals as an alternative e.g. the Makita battery terminal part number is 643852-2. Very inexpensive.
I thought I remembered from an AvE video that makitas star batteries can't be "hacked" like this because they have a chip inside that only delivers power when it recognizes an actual tool signal. Could be mistaken.
Matthis, du bist der Beste🇩🇪
There are a few models on thingiverse for 3D printing adapters for Dewalt battery. I use spade connectors inside nails and fix them to the adapter, so it slides into the connectors same way as connectors on the drill does.
hmmm wooden ball clamp and a light tail should fix the light up nicely mattias
As expected… Awesome!
If you bought these bulbs online, can you possibly provide a link to them? Afaik bulbs with a constant current* power supply in them are pretty rare (see bigclive's teardowns) so this project would be hard to replicate with most bulbs that one may have lying around.
*Edit: By that I mean a voltage independent buck converter instead of a simple resistor dropper
Look for the ones meant for low voltage rails instead of directly from mains.
Also Clive tends to take the cheapest bulbs he can find and only rarely takes apart the things that cost actual money.
You are crazy! This is so cool!! Make a bunch for power-out when you live out of town. Very cool!
Interesting!
Nice Idea, but very dangerous! 1. You don't have a deep discharge protection 2. Tool batterys that have multiple voltages, like for example the 60V/20V ones you have got typically parallel or put in series the different battery strings by the connector on the tool. if you discharge only one part of the battery, and it then gets connected to a charger or tool, there might be big scary equalization currents flowing.
The voltage is switched IN the battery, they are all parallel unless the tabls push the intenal switch all the way in
Nice man. Have an amazing Wednesday, Andreas 🇸🇪
Interesting. Now if you could use a flashlight to power a drill, that would be great. My drill's power died out last week and I am looking at my options.
Be careful doing this, I believe that Dewalt and Milwaukee batteries DO NOT have a low voltage protection circuit built into the batteries, they have it in the tool internally
Awesome!
an MR 16 socket cost is about a buck and a half Matt john Bicycle has the best idea with a tracking light. Thanks for the $$saving ideas
great idea Mathias. If you add a USB connector to the top plate, you might be able to use it on lots of different things. I am doing a series of making "portable power" (one unit using 4 Ryobi batteries) on my channel to be able to plug in lots of different electrical accessories. just go to my playlist called "Portable Power" for more info. I think this is a great idea to expand on.
Am I wrong in thinking this could ruin your battery if it drains too low?
Very clever
Nicely done! Do you have an Amazon link or something for that kind of bulb?
Great idea!
Really awesome.
3D Printing would be awesome for this project.
Although, to be fair, your solution was much quicker and looks awesome.
I guess you would come up with amazing things to do with a 3D printer.
some free battery adapter models, if you have 3D printer

Next up - switch, swivel head, soldered on wires
Make battery adaptors to use any battery on any brand of power tool
Never seen those battery transport covers, did they come with the battery when you bought it?
