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 Dremel info?

I just got a cordless dremel for my birthday. It's a 10.8v cordless and I was wondering if it holds it's charge well. I might want to take it back and get a corded one if it doesn't. I had a cordless drill and it lost it's charge all the time and wasn't that powerful, it stunk, that was a while ago though and the newer generation of cordless tools might be better. Any personal experience would be helpful.

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?

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..

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?

Power a cordless tool with a wall socket?

I have been experimenting with multiple scrounged mostly computer transformers and wiring them into the battery packs. Most of them work for a while then they quit. They can add a quick charge to bad batteries and I can use the tool directly while plugged in but once the transformer goes the battery soon runs down. I am using 18 and 19.2 volt tools and am wondering what voltage and amperage transformer would work or is this just a fatally flawed set up? I have no electrical background and my main motivation for this project is to give new life and function to otherwise wasted equipment. I would also like to see these unused tools possibly made available to those in less fortunate areas who could use the tools either from an AC conversion or to run from a 12 volt car battery which is common world wide. Thanks for any input

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...

What would happen if you used a 24v battery pack in an 18v cordless drill? Will this damage the motor? Answered

Thinking about overclocking some of my 18v power tools.  I can adapt 24v battery packs to fit into them.  Obvious advantage is they will run faster and should run longer with the extra power.  My only concern is can this damage the motors?  I think the only real risk is overheating but it I take steps to avoid that would everything else be okay?  I've also considered hooking two battery packs together to run an 18v saw at 36 volts.

How can I make an AC adapter that will fit a standard 1/2" drive 18V DeWalt drill?

I am sick of buying batteries or having them not stay charged very long. How can I make an AC adapter that will fit a standard 1/2" drive 18V DeWalt drill. I want to drop 120 volt to the 18V (with lower amps?) and do it in a hollow battery house so it will take the place of a battery when I run low on charge. You would think a cordless drill company would offer something like this as an accessory. I bought a cordless drill for the convenience, but 9 times out of 10 I am still close to an outlet. If I don't get an answer here I will just go ahead and figure it out on my own. But I really don't want to have to re-invent this wheel if someone has already done this.

24V Panasonic rotary hammer drill - battery and wires got hot (drill didn't) and drill stopped working. Answered

I have a 24V Panasonic rotary hammer drill, model EY6813. It came with two 3.0 amp-hr NiMh batteries, both of which had a problem with one of the contacts almost welding itself to the contact in the drill, and also in the charger. I stopped using those batteries. Now, using an external 7.0 amp-hr NiCd, it's worked fine until recently. The drill began to intermittently shut-off, then quit working altogether. I then noticed that the battery, the wire running to the drill, and the contacts in the drill were hot (battery was very warm, the wires & contacts were VERY hot). Any ideas about the problems with the NiMh or NiCd? Could it be the drill and not the batteries? The hot batteries/wires occurred after minimal runtime, so I don't think its a matter of overdrawing the battery, but I'm just not sure. The vent holes on the drill are not blocked.

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

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.

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?

As we all know the biggest problem with cordless power tools is the battery life.  One of the biggest reasons for battery failier is because the companies sell the tools with cheap chargers that cook the batteries.  The tools I have use 18v nicad batteries.  The chargers are the type that take about 3-4 hours to recharge a drained battery pack.  Does anyone know where I could find plans for an inexpensive circut that I could retrofit into the battery chargers to keep them from cooking the batteries?  Idealy a circut that would detect when the battery is almost fully charged and drop down from the 'fast charge' to a 'trickle charge' and eventually shut off completely when the battery is 100% charged. Be a super nice extra bonus if I could put in a circut that monitored the batteries while in storage, maybe topping them off once a week when I go a while without using them.
