Adding wireless charging to my mouse and keyboard

[@Keepthingsalive]

Wow, really cool, I didn't knew that you can remodel wireless charging coils

[@B8.5OZ]

same principle as electric motors. The larger the surface area and more winds of copper the more efficient, in the case of wireless charging the linear and flatter the better.

[@TMGeorge]

@@B8.5OZ Is it a Problem that the "loops" overlap? Should overlapping be avoided?

[@nicksonyap]

Very cool video & project! I did figure that it's probably easier and more effective to use those USB to magnetic connector / adapters so the charing cable would snap into the magnetic adapter

[@SasaKaranovic]

Thank you! I'm glad you like it. You are right, that's another option.

[@janemba42]

I've been thinking of doing this exact thing with my mouse, good to see i'm not the only one!

[@robswede88]

Nice video! But where did you put the QI PCB board?

[@deltaxcd]

You should have routed that could around entire mouse perimeter because the bigger the coil diameter the more effective it is

[@kimyongtan3818]

Appreciate your video, it’s really help! I’ve some question, can you still connect/charge the mouse using USB wire, will it be short circuit / any issue? Thanks in advance!

[@SasaKaranovic]

Depends on the module you bought. The one I have has reverse polarity protection (which you could add with single diode). I have been using it for over a year now and did occasionally have to charge it via USB and can confirm both methods still work. Again, you mileage may vary depend on the module you have, so double check.

[@kimyongtan3818]

@@SasaKaranovic I see! Thanks for helping! You are awesome!

[@warrenbinder3612]

How did you assemble the mouse with the wireless charger PCB? Like where did you put it...

[@SasaKaranovic]

I recoiled the RX coil to make it more compact and then the rest of the circuit is fairly flexible so you can mount it anywhere where you can find space. Usually there is a lot of free space but it varies from model to model so you will have to open yours and figure out what is the best place.

[@DennisBPierreLouis]

this is incredible

[@SasaKaranovic]

Thank you! I'm glad you like it!

[@akilis]

Hey there ! Awesome video, thanks for the tips ! Though I'm trying to figure out : do you think it is possible to put several TX coils together (in chain ?) to try and reproduce a full surface inductive mouse pad ? And I'm talking about an XXL mousepad, not the tiny little pads you can buy for 100 bucks from notorious companies :p Thanks anyway, great help !

[@SasaKaranovic]

What would be the use case? I assume it's possible although I think it would be very impractical for many reasons like power consumption, cost, labor required to integrate everything just to name a few. Ideally, you don't want to charge your mouse/keyboard all the time. Your battery life will probably be better if you dedicate a spot (or several of them if your desk area is huge or have multiple devices that you want to charge at once) on your work surface where you can leave your mouse, keyboard, headphones etc. and they will charger wirelessly.

[@akilis]

@@SasaKaranovic yeah well I kinda thought about that after posting the comment and also about getting a bigger coil instead. The purpose was to get a full surface charging mousepad to leave the mouse wherever I want, without caring for a specific spot to charge Kind of like the Logitech Powerplay thing but wider I realize a single spot is just fine haha

[@SasaKaranovic]

It's probably doable, just not very practical or cheap. :)

[@ContextG]

This little video has been a boon to me! I use a vertical mouse due to wrist strain and was looking to upgrade from a wired to a wireless one to have more freedom of movement. That's when the Logitech G powerplay devices came into my interest and I've been looking around trying to figure out how I could get something similar put together using a vertical mouse and this little tutorial video has given me more than enough information. I'm even going to try and see if I can get a mouse pad going with similar charging capabilities like the Logitech G powerplay one. awesome stuff! What kind of voltage and amperage were you looking at? or does it not matter because the onboard charge controller for the mouse and keyboard will be able to control and shut down the charging? any issues with the battery now after about 3 months of use?

[@SasaKaranovic]

Hey Context Gaming! I'm glad it helped. Let me know how it turns out, maybe post some pics and tag me. :)

[@ContextG]

@@SasaKaranovic for sure! I've got the receiver coil coming in with a new wireless mouse, so I'm gon a see if I can get it working well, and then see if I can find a transmitter coil large enough for the mouse pad.

[@ContextG]

@@SasaKaranovic quick question! I'm trying to find some larger transmitter coils, something that's almost 4 inches in length and 3 inches in width, would you have any direction to point me in so that I might find some?

[@christiaang]

Does the wired USB charging for the mouse still function as well?

[@SasaKaranovic]

Excellent question! It does. Although I've used it only once (after adding the coil) to check if it still works. Since then it's been wireless charging only for me. :) If you intent to use both methods, I would recommend that you try adding a Schottky diode just to "disconnect" the two sides. Anode on coil side and cathode towards USB +5V connection. This would prevent coil back-powering when being charged trough USB cable.

[@JustStarcraft2]

Hey do you know if this qi wireless works on AA battery powered mouses? Will the qi wireless charge my eneloop battery inside my Orochi V2? Or do I have to solder on some lithium battery for this to work? If I need to solder lithum battery, can you link me the highest watt battery I can use from aliexpress etc? Can I just buy a Logitech Mx master battery replacement and solder onto the Orochi V2? I don't care about mouse weight, I just want a highest watt battery so I can charge less. Thanks!!

[@tknx2948]

Why not do it around the sensor? Does it not work there? Would be more central.

[@SasaKaranovic]

You can place it wherever you want or have space. As long as you can have coupling with the TX coil, you have wireless charging. ;)

[@XHULIOZ]

I have an ROG Chakram X Origin It looks like it has the same enclosure as the ROG Chakram X which has wireless charging The enclosure even has a sticker called wireless charging area Got confused by it and bought an expensive mousepad with wireless charging just to find out the model difference Will try to get a guy that works with batteries to give it a try diy ing this Any way to reach out if we need to ask any question?

[@SasaKaranovic]

Hey @XHULIOZ! I would highly recommend if your mouse is still in warranty (or even if it isn't), maybe it's worth reaching out to Asus and explaining your issue and checking if you can upgrade to the wireless charging one? Modifying a mouse to have wireless charging is not that complicated, but at the same time you risk potentially damaging your mouse if you don't know what you are doing or make mistakes. Also depending on the coil, how you add it to the mouse, the charger etc. your range might be great or it might be charging only in one spot. So consider all of this before making the modification. And if you do end up modifying your mouse, let me know how it goes or maybe even document it and share with others who might have similar issue in the future.

[@XHULIOZ]

@SasaKaranovic I wish I could but I live in Albania and its not available at all Will definitely let you know if I go through with it

[@somewhatideal]

Hello! First off, amazing tutorial. I opened up my mouse and I can't seem to find where to solder the points to the pcb. It's the Fantech Helios Go XD5. I do see two points on top of the usb c and it says R31 and R31. Could that possibly be it?

[@metim10]

Can you tell me if it is possible to do this on the surface of a table in the size of 30cm x 25cm? Then, if I put a keyboard or mouse with that adapter you made, it would always charge if it was inside that 30x25 surface. If possible, how could it be done? I ask because I've never seen a very large wireless charge base.

[@-Sethius-]

Could you elaborate a bit on how to tell where to tap the wireless charger leads onto the mouse PCB? My mouse has a micro USB port too, I'm just not sure where exactly I need to solder the + and - to from the wireless charger. Just anywhere I'm getting 5v as close as possible to the USB port, or.. ?

[@SasaKaranovic]

If your mouse is charging the mouse battery via USB. Then you need to find where your VUSB and GND connections are. Since they enter the board trough the USB connector, that is the best place to start (find VUSB and GND pads on the connector). However, you can easily trace those connections to a capacitor, test-point or any other place where it is more convenient for you to solder. As long as they are the same net/rail, you should be fine. Again, keep in mind that you want to solder to VUSB rail and not just any +5V rail. Mainly because your mouse might have features like reverse-polarity protection, fuse, current sensing etc. that you don't want to mess with. Otherwise it might cause faults or some other "undefined behavior". Let me know how it goes or if you need more help. Also I would love to see how it looks, so please do share your result. :)

[@-Sethius-]

@@SasaKaranovic I really appreciate the info! My mouse is a Rival 650 wireless in case anyone else comes across this and wants to do it for themselves. There are clear VBUS and GND pads to tap into on the bottom of the PCB, so it was honestly quite easy once I had everything apart. I'm surprised how well everything fit - it was like I had the perfect amount of space for the charger coil. All I had to do was cut off a bit of the plastic / rails on the bottom case to get it to fit snug under the PCB. Here's some pics: imgur.com/a/lvP5j3R Thanks again for the video and info! I'm fully wireless now. Next I think I'll do my Xbox controller. 👍🏻

[@sofiangr]

why not making a mousepad with a modified coil on this transmitter?

[@SasaKaranovic]

You can still do that. You can get matching Tx and Rx coils and you are good to go.

[@mastalock]

I have an MX Revolution, no ports. Where would I connect the coil?

[@SasaKaranovic]

Looking at the teardown pictures, you should be able to solder to the two pads that are used for charging (on the inside there is a lot of space and also many test points). Just verify which one is GND and which one is VCC and also make sure voltage between them is +5V (when charging). Then you should be able to add your wireless coil. Let me know how it goes! :)

[@greyreynyn]

Is that keyboard straight off a lenovo laptop? I love the laptop keyboard, but I bought a standalone keyboard from them and it was totally different.

[@SasaKaranovic]

It's a Lenovo "ThinkPad Trackpad Keyboard II" (try saying that quick). I have been using it for couple of years now and I'm pretty happy with it.

[@greyreynyn]

@@SasaKaranovic that's amazing man, thank you I'll have to get one to try out!

[@nadina492]

This is awesome! I want to do this on my G900 chaos spectrum. Could you tell me how can you identify the PCB lanes for GND and VUSB? I've looked at the teardown pics of my model but I can't seem to identify it. Thanks in advance!

[@nadina492]

I've dug more into it (I'm new to this electronics stuff), and it seems that if I can find an empty capacitor slot, I should be able to solder my positive and negative cables directly to it. My model has a "C1" slot unpopulated, so I should be able to solder directly to it. Am I on the right track?

[@SasaKaranovic]

​@@nadina492 If you have a multimeter, put it in continuity mode and probe from your USB connector to that capacitor. It's very likely that you will find VUSB and GND on that or another capacitor. That's what I did in the video. Also the closer you are to the USB connector, most likely it will be easier to find a decoupling capacitor that is connected to VUSB and GND. Let me know how it goes!

[@gruzinskasgvidas7468]

Does it work with classic mouse pad with QI charging?

[@nathannathan9137]

Will you make large mouse pad that charge those keyboard and mouse simultaneosly in next experiment?

[@SasaKaranovic]

It should not be too hard to modify this project to do this. I personally find it "better" to have separate chargers but maybe in the future I do it, who knows. But no promises.

[@nathannathan9137]

@@SasaKaranovic i am curious, the “better” way but separate chargers.. :D

[@manuelma416]

Genau was ich nuche, nur würd ich gern meine logitech harmony mit einen wirless charger modul ausstatten....

[@SasaKaranovic]

Nice! This method should work for most devices regardless if it's a mice, keyboard, headphones, remote etc... As long as they are powered/charged via 5V USB, it should be possible to modify them to use wireless charging.

[@argg.x]

Is it possible to reuse a Razer charging dock or one of the GPW docks with another mouse? Like adding the pogo ping or whatever is needed?

[@SasaKaranovic]

I'm not sure what do you mean. Bust I'm sure you can hack it to add wireless charging or to make different peripherals compatible. There is a good chance that someone already did what you are trying to make, so Google and/or KZbin may be a good place to start.

[@argg.x]

@@SasaKaranovic OH sorry, i meant Pogo connectors, is it possible to install Pogo connectors in my mouse and do a simple wiring to the battery for charging? or how hard would it be? :) Thanks!

[@SasaKaranovic]

You could add Pogo connectors (i.e. heat stake them into plastic, drill or some other method). But I'm not sure how that would be related to adding wireless charging. Piece of advice; NEVER connect external connection/voltage directly to your battery. It's almost always a very bad idea. Also keep in mind that playing with batteries can be a safety and fire hazard, so make sure you know what you are doing.

[@glenharrison8524]

Do you still have the STL files for the 2 models you printed please?

[@SasaKaranovic]

Absolutely, I've uploaded it to sasakaranovic.com/download/wirelesscoilstep.zip Although I'm pretty sure you can model something way better in Fusion 360 in a couple of minutes. :)

[@slamz92]

The coils are not availible anymore? Could you suggest a substitute?

[@SasaKaranovic]

Thanks for letting me know. I have updated the video description with search queries. There are always multiple sellers that sell the same item, so you could use image and/or description to find the item if one of them runs out of stock or the find a better price.

[@w8llyt890]

[@akilis]

Hey there :) I finally managed to get some coils and I'm now getting to hard part : I'm really not sure where to solder my coil to the mouse pcb (a Corsair Harpoon RGB btw). The thing is, the usb port is on a tiny piece of pcb with 4 pins pluging in the main pcb. And on this very pcb I'm kinda lost haha. If anyone can give me hand I'd be very grateful, thanks ! :D

[@SasaKaranovic]

Looking at the teardown pictures, the PCB clearly shows exposed test points (tiny gold circles with white labels near them). You can use the two labeled "5V" and "GND" to attach the coil to. I don't have that mouse nor the coils you have, so please double check and make sure you know what you are doing. I take no responsibility if you destroy anything. :) Let me know how it goes!

[@akilis]

@@SasaKaranovic Well it worked and I'm very glad of your answer ! Then I reassembled everything and the sensor didn't work, I guess I already screwed it when I was looking for a spot to place the coil. Also, when I disassembled the mouse again, the 3 pin receptor for the battery went off and I'm not sure I can fix it. Anyway, it was really fun to do it and I thank you very much for the tutorial anyway ! I'll sure test it on other mice haha
