Corded to cordless

I've seen lots of instructables on turning cordless tools into corded tools, but not a single one the other way round. I want to know how it works the other way round. How do you make a corded tool into a cordless? Please, please help!

Cordless Telephone Bridge

I'm trying to figure out how (or if) I can use an old cordless phone as a tranciever, wiring in an rj11 jack to the phone's reciever to essentially make a cordless phone "bridge" so that I can use my desk phone in an area without phone cabling by plugging it into the cordless phone's reciever. I've tried the phone over power adapters and haven't had great luck with 'em, so I'm trying to think outside the box. Anyone have a suggestion or two?

Why Cordless Drill (Bosch 7,2volt) do not work using Laptop Adapter

Hello all.. I got problem with my cordless drill. It's battery is leak and i need to replace it using Laptop Adapter power suply. I have HP laptop adapter with Voltage Output 18,5Volt 3.8Amp. I just connected the + and - of laptop adapter to the cordless drill, BUT it do not want to turn and ONLY MOVE SEQUENCE (move-stop-move-stop-move-stop....). Its move is so strange for me, it's like pulse voltage because the drill just move for a moment then its stop, then its move and stop and always like that... I don't know is it DC or AC, and I've try to make circuit to make its voltage become DC using 4 diode and capasitor, But the result is same (move-stop-move-stop...). Then, I try to connecting the cable adapter to the drill and then pull off and connecting again with rapid sequence. Then the drill want to turn fastly... Please Help me, how to solve this, i need this adapter work for my cordless drill.... I've make a test to, I used AC dinamo (not DC dinamo motor) and connect it with the Laptop adapter, it's turn normally and fast... Please anyone here help me...

Automatic LED light for cordless drill?

As far as I know, DeWalt has not incorporated lights into their cordless drills as some other manufacturers have.  Could someone make an LED light which would come on when the magnetic field produced by the drill motor is sensed?  Perhaps a sensor taped to the drill body, and a small LED light pointing forward, or a ring of light around the drill chuck?

convert 12v cordless battery to solar charge

My first post- great site! I'm a complete idiot when it comes to electrical; does anyone out there know of a way to charge a 12v cordless drill battery with a solar panel- the eventual end result being to power a bank of LED lights and can all LED lights be powered with DC, if so how many could I expect to run?

Reusing old laptop & cordless components

Hi, I have an old laptop which stopped working due to variety of reasons (I suspect it was mostly a SW issue). I have reason to believe that its screen and lots (or most) of other HW components still work fine. (I have done the easy part of removing its HDD and am using it like a portable disk). Can someone suggest or point me to instructables for to reuse components from this laptop? Same for my cordless phone which is a Panasonic KX-TC1486B . (I have taken the phone apart already and have labeled parts as originally found just for ref). Thanks, Sushrut.

Brain Doctor Uses Cordless Drill to Remove Tumors

A British doctor is in the news for using a cordless drill, a Bosch model, to drill into patients' heads and remove tumors in a Ukrainian hospital. While cordless drills are fantastic things it's surprising to see brain surgery as one of their uses. Now if only Bosch would put that on the package.Minutes later the team of doctors, including one of Britain's most eminent brain surgeons, begins to break into the skull of their fully conscious patientœ with a £30 Bosch PSR960 handy-man's cordless drill. Amazingly, and despite the low-voltage tool running out of power halfway through the process, Dolishny's operation is a success, with his tumour skilfully excavated at the hands of Henry Marsh.The procedure, captured as part of a documentary to be screened on BBC2 later this month, was a routine triumph for Marsh, who regularly takes time off as a consultant at St George's hospital in south London to travel to Ukraine and save lives despite having access only to primitive tools. Also great is this list of makeshift ideas at the bottom of the article:- In 1995 two doctors on a flight from Hong Kong to Britain operated on a woman with a collapsed lung using a scalpel, a knife and fork and a coathanger to push in a catheter.- In Iraq in 2004, an American medical journalist removed a bullet from a marine's head with a drill used to put up a tent.- In 2003 Aron Ralston, an American climber, cut off his arm with a penknife after it became trapped under a boulder in Utah.- The following year Ines Ramirez Perez, a Mexican, delivered her son by caesarean section with the help of three stiff drinks and a kitchen knife.

Jobmate cordless screwdriver

Hey guys!!! Long time no see, I have been busy doing other things in my life and coming to check on here completely slipped my mind, I feel so bad now after seeing how many comments I've missed out on replying on. Also, I noticed some people around here have a PRO beside their name, what is that about? Anyways I have a question I wanted to ask. I bought this handy little cordless screwdriver at a yard sale yesturday, and got it home, plugged it in to charge, and it seemed to be holding a good charge, I used it to change some tweeters in my tower speakers, it has good torque, and good speed. Overall, for $1 I was happy with my find while out on my little adventures. Well, I went to use it this afternoon, and it was dead :( Apparently the Ni-Cads are toast. The problem here is, theres only one screw in the side of the unit, and it only lets me pry half of it open, I can't get the top off of it, there seems to be two metal tubes holding the top on. Does anyone have any idea how I'd pop this thing open?? I want to see about replacing the two cells inside with some rechargeable energizer AA's I have, would I not be able to charge them with the built in charger?? They are NiMh however..

Need help with power supplies

I've been reading about electronics for a while and watching the Make podcast and I've finally started making my own projects. Anyway I have some cordless tools with 3 extra batteries but only one of them still takes a charge. So I thought it would be cool if I could put a power supply in one of my dead batteries so that I could plug it into the wall. I've been looking around my garage and thrift stores for a wall wart that would get the job done (the batteries are 19.2V Craftsman batteries I think they pull about 2000ma) but the closest I've been able to find is an old laptop power cord has a DC output of 19v and 3.9amps. So I'm not sure if that will work or if the extra amps will burn out my tools or something. Does anyone know if it would work? If not how can I dial down the amps?

DIY ±18VDC to power a dead cordless drill

Hi! My last battery died on my cordless drill and i'm trying to transform it to a corded drill. My plan was to use a microvawe transformer along with a bridge rectifier (KBPC5010  Bridge Rectifier Diode, KBPC Series, Single, 1 kV, 50 A, 1.2 V, Module, 4) to power the drill. 120VAC from the wall to, I wish, 12to18VDC. The problem with this is the voltage given by the output of the microwave transformer is of only ±3VAC. Any sugestion?

14.4v Milwaukee cordless drill using 18v battery packs?

Have an excellent drill from Milwaukee with tons of life left but having trouble getting the 14.4v batteries AND getting them to last. Anyone adapted the 18v batteries to a 14.4v tool. Is it possible. I figure it won't come recommended. I just hate to trash this tool. Thanks. Dave

Ideas for a counter balance

I am looking at ways to replace the weight of the batteries in a cordless drill (the batteries leaked, and they are not sold to my knowledge anywhere in THIS country); after wiring in a power supply (making it corded).   Any suggestions?   I have thought of a few but nothing seems overly viable at the moment.

Power Tool Corded to Cordless

Hi 'nstructables I'm building a hovercraft (see several tutorials on Instructables - the one with a leaf blower) and my leaf blower is corded. I don't want to buy 25 miles of Black and Decker High Power Extension Cabling so I'm planning to convert to cordless. Here's my idea: (in visual) Is there anything I need to add? And if so, how do I make the "12VDC-240VAC" inverter described? My blower is 1600 watt. Thanks for any help! (Black and Decker)

Cordless drill power supply

I am using an EFUEL 30amp 18volt 540watt (model sk-200013)  power supply to power my Ridgid cordless tools. A dead battery was gutted and a power cord was soldered onto the circuit board inside the battery enclosure. My problem is that I encounter an OCP (overcurrent protection) error if I do not slowly power up my tools. I can live with this except for tools that are not variable speed (circular saw). If a Ridgid cordless tool demands full power at start up then the OCP error condition is triggered. My question is that I have heard that the installation of an external capacitor will eliminate the ripple effect and smooth out the power demand on the power supply so that any tool used at 100% demand at start up  will work without causing the OCP error condition. Is this correct? If so, can anyone tell me the type and value of the capacitor to use? Any help is appreciated. JEM213

can we make a battery pack for a cordless tool that has a cord?

I run out of battery power and sometimes it would be nice to use my saws all with a cord instead of waiting for the next battery to charge. I would like to take a battery apart and stick a cord in it and then need to know what process to make the 18v power come out to the tool from the battery pack. This sounds to me like it should be really simple so if any of you smart people know how to do this pleas make an instructable for the rest of us.

Cordless Car Heater

Hi all, I am camping in my SUV in northern CA. It's a bit cold at night and in the morning, and can stay warm with blankets and a sleeping bag, but, when I get up, and want to change clothes or just sit, it is really cold. It's a 1999 Ford Explorer V6, and I am trying to find or make a device that would heat the interior without turning the engine on.  I've seen handwarmers on amazon and ebay, but I don't see anything that warms that much space without a plug and without CO2 emission. Any ideas?

Voltage regulator for trailer brakes

Im planning on building a motorized trailer dolly for my travel trailer, however i want to make a dead mans switch for the trailer brakes.  I was wondering if I took apart an old cordless drill if I could use the trigger as a voltage regulator to regulate the voltage to the trailer brake system.  Without getting into specifics of how it will connect to the regulator, I figure I would have like a bike brake handle that while applied the trailer brakes would be off, but if released that the trailer brakes would be applied incase the trailer started to roll away from you. Any suggestions other than "Go buy a trailer brake controller" would be appreciated! :)

Any Power Source USB Charger

So here what I have in the works, I'm trying to make a pocket sized gadget that will charge a USB device from anything,  Normal 110v AC, And anything from 4 AA Batteries to a 28v Cordless tool battery,  to a Car Battery, Solar Panel in the middle of Mars, etc, Anything giving off Between 6-35V (Be nice if I could find a 7805 that had a Vin (Max) of 40V, Several manufacturers make 36v cordless tools) . I'll use alligator clips to attach to the battery of choice, and I'll throw in a Diode bridge to make it idiot proof. I plan on having a switch between an AC and DC Circuit. And of course, I'll throw a decent sized heat sink on the regulator. Any Suggestions? I'm not the most electrical savy person out there, so if you foresee any problems, let me know.

Harvest Grain- with a Hedgetrimmer?

Has anyone tried cutting tall grass with a hedgetrimmer? It does resemble a sickle bar mower, at least superficially. I've never quite gotten the hang of the scythe, and although the gas chainsaw does work, it's an awful lot o noise. This year, the slender wheatgrass, which is usually xeriscaping and erosion control will be harvested for chickens ! I'm thinkin of buying a Ryobi cordless trimmer.

Landline and mini speaker & microphone : can one use bluetooth mini speakers ?

Hello,Is it possible to use one of those small bluetooth speaker + microphone sold everywhere with a corded phone (cordless but wired to rj11 modem-routeur) to achieve some kind of JABRA-like system ?This is intended for me (light hearing impairement) and my parents.Of course the Bluetooth would not be used as bluetooth but as a "wired" speaker+mic to the phone base (with 3.5mm audio cable as for headset used by gamers..The idea is to get a louder volume than the handset or base of a corded phone can provide.and the problem of sound quality + cuts that arise from this mode of use (listener cans speak but with a delay ...) Please, don't answer me to buy "Jabra" or buy "amplified" dect phone.Just in case, I dream of a mini speaker not bigger than a glass o water connected with a lapel microphone (or replacing the microphone + speaker of my GIGASET handset ...)Any answer and/or suggestion would be appreciated.

Useful tools

Cheap, cordless drills are amazing tools. Take one apart and attach a speed controller, you got a motor for a robot. Also, they have good high torque motors that can be used for all sorts of things. A $50 RC transmitter and a receiver make good remote uses, such as remote detonation. More useful tools are pneumatic cannons. I've used them from pressure testing to damage testing. WHat are your useful, unconventional tools?

It was a disc like an advil pill with two leads. Where would I find a replacement? I've looked on digikey.com but can't make heads or tails of it. I imagine you would want it to stop charging at 70 degrees c like a lot of r/c packs do.

Multiple drills sharing a single power source

Would it be possible to run multiple cordless drills off the same power source? I do not want to run the drills all at once, but rather have them share the power source. I was thinking of modifying an ac adapter with a voltage and amperage less than the tolerances of the drill. Are there any safety concerns? If I do this will I blow myself up? Could I run them at a higher voltage/amperage? Is this idea dangerous and stupid or just stupid?

Wifi Voip Phone

The call control protocol of the WF01 is based on SIP V2 (Session Initiation Protocol version 2, RFC 3261) open standard, which is interoperable with major SIP-based call servers, IP-PBXs, and other standard SIP-based client devices. The WF01_V2 is compliant with the IEEE 802.11b standard and interoperates with any existing 802.11b or 802.11g wireless AP and gateway. It may be used as a cordless handset for residential users or for business users in an office environment. The small form factor of the handset is easy to transport and allows users to place VoIP phone calls in public 802.11-based environment.

Wireless headphone with Microphone

Can anybody tell me how to make a wireless headphone and microphone. Both microphone and headphones should be wireless. I found that one can buy a wireless headphone or a wireless microphone, but not a combination of both. Why I need it. I make long phone calls, during which I need to walk around. If I use a cordless phone, I have to keep holding the receiver with one hand all the time. If I use a speakerphone, everybody around listens to the conversation. Therefore I need one wireless headphone with mic.

My goal is to do this for under $40--the cost of buying that way overpriced pager system you've seen advertised--and for me to learn while doing this. After reading another instructable, I was inspired to use a cheap radio controlled car.

It's great fun and probably more entertaining than it should be. Is there anyone else out there doing something similar? We're always looking for ideas to make it better. We're also always looking for new competitors if you're local and interested. There are classes for every level from a two wheel drive 'box stock' type setup all the way up to AC and cordless drill motors on tractors that only have to be 50% K'NEX. Thoughts? Interest? Offers of sponsorship? ;)
