Glitches with the Instructables Editor

While trying to make Instructables with the Editor, I have come across two glitches (if this is not the place to report bugs and errors, please inform me).1. The text boxes for the Intro and the Steps editors refuse to let me copy/paste anything into them. The pasted text appears for a split second, then disappears.2. The same thing happens with links. I type in a URL and the text for the link, press OK, will show up for a split second then disappear.I hope this helps to make Instructables a better place.

I would need the same type of transmitter like any bluetooth mouse would have inside. The mini pc I am building has both bluetooth and wireless display.Parts list so far15.4 samsung screen pulled from a Dell laptop modle LTN154W1-L01Control board for the screen with hdmi ebay 30$ link https://www.ebay.com/itm/HDMI-DVI-VGA-LCD-Lvds-Con.. 12v 3 amp power supply for the screen controler I already have but later I would build voltage control unit that would charge or power the whole unit. Again YouTube has videos and links for the part for this. And I really don't want to have a bunch a supplies to run it. While prototype it I will the final will run from the laptop I got the screen from. It should plenty of power for a single board computer like the new pi 3 to be added and the audio amp15.4 4 wire overlay conversion many sorce's about 50$ link https://www.ebay.com/itm/15-4inch-4-Wire-Film-to-F... $Ar1100 touch to usb mouse adafuit 10$ link https://www.adafruit.com/product/1580Hdmi wireless receiver. 20 to 40$ depending on features like if it has chromecasting and such I just need video so I think the 20$ unit will do nice. These can be found in many places, so I would think this to be open end item depending on features the builder wants. I would buy the best you can afford to leave it fexible .The last thing I need to make work would be usb transmitter to make the ar1100 bluetooth or matched pair of 2.4 dongles usb this is the only item missing. I could test the whole set up but would have run 1 usb cable, but that's a deal breaker for full wireless... If I had a old bluetooth mouse and knew how take its transmitter out, that work but a bluetooth usb adapter the would plug in the ar1100 board would be the thing I need.If someone would know how to remove the mouse transmitter and wire it to male usb plug I would be happy to buy it. I real want this to made from as much recycled parts as possible.I just don't want to have run a usb cable from ar1100 to the pc.I don't think the same usb dongle that's used to the pc is the same as the one used in every bluetooth mouse or keyboard. That's my idea for a wireless touchscreen handheld All the parts are easy to get I just need make the ar1100 usb board and wireless usb transmitter. The pc would use GA-h77n-wifi mini itx as it has both bluetooth & wireless display and wifi.Part 2The idea sound lol! I want to build a frame for the screen with speakers and laptop battery and used the power supply from the Dell laptop I got the screen from, that would need a small amp. Since the receiver is hdmi, I would think the audio would be there if not that would be simple to just use a bluetooth stereo headphones and run the earphone wires to the small audio amp.I would like any comments on this idea and a sorce the one part that missing the usb mouse transmitter for the ar1100 and this could be built.So What do you folks think? A portable monitor 100% wireless that could even double as touchscreen remote! I even thought down the road to add the new pi 3 to it as that would completely independent as low power tablet or connect to the pc that nvidia gpu and could stream pc games to My Nvidia shield too. With all the power of I7 2700k oc to 4.2ghz.The possibilities here are endless you and all kinds a features adding a mic and Webcam for video calls with sckype or google voice and messenger and bingo u have a voice and video over IPThis do able you think?All comments good or bad give to me straight.Oh but go easy on the grammar thing. I technology geek but a 56 year old high school drop out. But hay at 37 I was disabled with fractured spine by time I was 40 I did all computers repairs for my local high school and was building white box computers out of my home office. If there is 1 thing I have learned in this life anything is possible but you have to try!Please be positive and constructive with your questions and comments.

But i dont know what else i would need so i can get the information of the position to a raspberry pi like what types of thread do i or is there some thing else i need as this is my first time making something like this Thanks in advanced

Can build a coil gun using Direct-on-line technique?

Hello,I'm trying to build a coil gun and am stuck with this problem.....the gun I'm trying to build will be using a 5200mAh 22.2V 25C battery as source and a 16swg wire for coil in series with a N-channel power MOSFET (IRLR7843) as a switch. I'm using a 0.2ohm resistor to draw 110A current from the battery....but the problem is the resistor I'm is not capable of handling this huge amount of current it just blows up. I've looked for other alternatives but the problem there is with the size, which is not feasible in my case. so now I'm looking for a suggestion for some kind of resistor that comes in a small size which can handle this current and possibly has managed to stay out of my sigth.....or if I can go ahead with the DOL and eliminating the use of resistor entirely and connecting the coil directly to the battery( I know that might be foolish tho)
