Question by g3holliday
Okay so the first question is, could I charge an Electric Scooter while it's in use. The Scooter in question is a Bullet XCT 85, which from what I can tell is a Xiaomi M365/Pro Knock off.While I have it plugged in and charging to the wall, I can still turn it on and use the throttle, whether it's still charging (as the wall charger would indicate) or the scooter has safe guards to stop the charging from happening while it's powered on, I got no clue.Second part of the question is, the scooter supposedly (I haven't and don't want open it up to check) has a 36V 7.8Ah Battery. So with that info would I thearetically be able to put together a battery of also 36V and different Amps to either 1. Charge the scooter on the go or 2. Have a battery back up, for when I haven't got access to a wall charging option.As for the extra battery, the current idea for cost vs. capacity is get 3x 12V 9.8Ah Li-ion Batteries in series to make a single 36V battery, with the right plug on the end to plug into the scooter. And possibly some sort of battery meter to be able to read the battery level.Side Note - I don't have any electrical knowledege, besides the basics. But I'm a quick learner.

You suffer for days after one of these tiny vampires got you?The itching drives you mad?And unlike some people your bites always get worse from day two onwards?If so, then you might have the same problem as I have...No matter how much hate and disgust you show, these mozzies just love you.And as this wouldn't be bad enough your body totally overreacts every time.A bite for me meant numbing cremes or sprays, anti-histamines and if doubt putting a heavy duty bandaid over it so if I forget the scratching won't do too much harm.Despite all this 5 to 6 days until the itch, swelling and irritation stop...A few weeks ago while fishing I had a nice chat with a man way into his 80's already.He laughed when I started to spray all uncovered parts of my body with tropical strenght insect repellent.Told him my reasons and then he said I should try something he used during his army times for bites of unknown critters.In the jungle they often relied on local guides and they provided a solution that seems to be totally forgotten these day - even I did not know it LOLTheory behind it...If you know these "insect bite clicker" then you already know how it is put into comercial use - without ringing much relief.Whenever something bad enters the body there is a reaction to fight it off or dispose of it.Problem with insect bites, be it mozzies or sand flies, is that all this bad stuff is concentrated in a very tiny area.And being mostly skin tissue makes it hard to deal with it.By applying pressure and massage like motion to the bite the contaminent are spread through the tissue.If you leave a small dint with little to no color left after 2 or so minutes you doing it good.Try to use something hard here, like a spoon, bottle cap, end of a screwdriver - whatever is slightly rounded and solid.You will notice that the itch gets quite bad once the bloodflow starts again and within minutes the bite area will swell up and form a more or less evenly formed hump.The hump will be pale in color while around it the skin is slightly red from the added bloodflow.Don't scratch! Just wait until a nice hump has formed where you can clearly make out the rim.Now use the same pressure method as before and spread out the hump while constaly pushing it in and "wobbling" around to massage the area a bit.Do this as before for about 2 minutes and if you still see a destinct difference between bite aea and surrounding tissue continue for a bit longer.Should not take more than 5 minutes to have the area nice and even again.Wait again and check for new singns of swelling up - there should not be any.If there is simply repeat one last time.The remaining itch will go away within about an hour instead of days and there won't be any severe after effects from day 2 onwards either anymore.It can help to use heat as well.For example by heating up the spoon in some hot water before using it.But keep the heat at a level you can tolerate!!! Do not heat the spoon to the point where you feel pain from the heat.Try it out and report back! :)

Ok, here's one I thought I'd throw open to the masses.... I'm knocking off the last of a fully automated self-sufficient watering system that runs completely off grey/rainwater. However, the coke can guttering is not working in this position as it has previously :( I was thinking of using PVC piping, cut lengthwise for guttering. However, I'm working out the logistics of cutting it. It can't be cut directly in half - this would be too shallow to catch the runoff from the chicken shed. and funnel it down to the tanks, so I'm looking at removing a chunk of the top. And I also have no table saw. Wheee. What I do have Dremel (x2) with associated cutting wheels Jig saw (With associated plastic cutting blades) Circular Saw Mitre saw Hand saws (tenon, crosscut, hack, pruning, etc) So, here's one that I'm throwing open. With the tools I have, how would you do it? I'm leaning towards the dremel, but there would probably be issues with maintaining a straight line (not that I care about some warp, it's a gutter) Ideas? *EDIT* Ended up using a jig saw with an acrylic cutting blade. Worked a treat.

I have a 16 gigabyte flash drive that's relatively empty (13.7GB free space), and I was trying to put a 5 gigabyte .ISO file onto it. However, when I try to copy the file to the flash drive, I get an error saying there is not enough space to put the file on the flash drive. I know this is not true because I have over 13 gigs of free space. Is there any reason for this weird error and is there any fix? This is kinda important.

I need help please anyone. I have bought another CNC shield recently, goes by the CNC Shield ver 2.7 name. The board has www.lubandiy.com printed on one corner. There are 8 optical isolators on the board for the limit switches and a socket for a Nano. Also there is a heavy duty hexfet near the laser connections. I am not able to find out much about this board, even though I have asked the seller and even a few other sellers that are on ebay. I went to the website as shown on the board, but it is all in Chinese and after trying to use Google translate was still not able to find out any further information. The board looks well made and seems to have a lot of good features, but lacks the needed info to be able to put it to good use. I am not sure if the board has a laser TTL built in or not, it is possible due to the hexfet being there, There are two heavy duty connections (two pin each marked + - ) and a small connection with a xh2 socket that could be for a laser or maybe a fan. Can't get any further info on it. If anyone can help with info, please let me know so I can start to use the board with my machine build. I have managed to program a Nano with GRBL 1.1f and it works OK when testing the board on a dry run, no motors connected or laser.

Curious if some of the electronic gurus might have the answer to this. I am looking to build a two channel (A/B) microcurrent (allowing from 20 - 600 microamps) with selectable frequencies ranging from 3 to 970 Hz). This is based on a medical device that I'm looking to replicate. I've figured out some of this but again, considering the wealth of knowledge here I'm sure some would know the best way to build this. Oh yeah, I figure using a rechargeable battery which could be whatever voltage is best recommended. So what do you think???

Question by ambrosiaceae | last reply
I recently ordered a REX C100 for my electric melting furnace project. As it came already with a SSR and temp sensor I only added a sensor capable of reading more than 400° of the supplied one. These controller are dirt cheap and have lots of support in the modding community - although you now can get them new in all variations so no more modding required. Internally they run on 12V DC, so even mobile use is possible (but this time after modding). My problem with this controller started with the not included manual. As it is no China clone but an original from RKC Japan, I downloaded their manual and tried to adjust the max temp settings as well as changing to the thermocouple. To my surprise the menus for that simply did not exist on my model. Reading a few more manuals showed that to get to the "initial or factory setup" you need to change the lock code. Here things get confusing: Once in the lock menu setting most manuals state to enter "0000" to activate the hidden menus. (Mine was alreay on 0000) Others state to set the code to "0100". In any case you have to hold the setup key for a few seconds to store the changes and after that hold the settings and shift key for about 5 seconds to enter these factory menus. After being close to send the unit back I tried different code combinations and finally found that "1000" actually activates the hidden menu on my model! But again there was no joy as several vital settings still did not show up. To finally get all settings another step is required: The first item in the hidden menu is "CODE" and it shows as "0000". After changing this to "0001" the setup key can be used to get to the settings to change the max and min temps. Once all this done the controller actually shows the selected sensor and if Celsius or Fahrenheit is used at the start and from now on simply by clicking through the hidden menu with the setup key you can get to the min and max temp settings again. I hope this info will help someone running into the same brick walls as I did...

I Bought myself a Lego RCX for Christmas this year... I wanted to use it with my windows 10 PC, after inserting the software disk(s) and realizing that it was meant for windows 98 and it won't work on my modern PC I went ahead and installed virtual box and ran windows XP on it. I installed the Lego software (which installed without any problems) but when I tried to launch it there was a "Not Enough Disk Space Error" Even though the virtual hard drive has 200GB free. Any Ideas?By the way, I tried the "Emulator" that is built into windows 10, it also didn't work (The one were you go into properties, compatibility, and change it to windows 98).I Also tried Windows 98 in virtual machine, when I launched it there was no "Not Enough Disk Space" errors, but there was a error that said something along the lines of "this program requires 800x600 resolution minimum" When I went into the control panel my resolution was 640x480, and I couldn't move the slider to make the resolution higher for some reason.And I do not want to use any of the other programs for coding the RCX (Bricx command center, etc).Any Help would be appreciated!Thanks.

I have Photodraw 2000 on my computer from several years ago - I copied it onto my newer computer and I use it all the time to add text, borders or effects and to correct old photos or erase backgrounds. I use my photos for various purposes, for teaching and family use, so it's good to be able to do lots of things with the photos in just one simple program I love Photodraw- it has so many uses and is easy to use. I never got the hang of using layers as in paint.net (which I've tried ) and Photoshop (which seems so expensive and complex). Does anyone else still use Photodraw or am I hanging on to a dinosaur here?

Hi,I am trying to get a project started that requires up to 150 x individually addressable LED's. Each LED needs to be programmed to flash individually. Ideally the project would be controlled by an Arduino or similar and would be battery powered as it needs to be portable. The whole system needs to be operated with a simple On/Off switch.The flashing sequence for each LED is critical so if a piece of software is available to easily set up and control the flashing sequences, then that would be a big bonus.The LED's will be mounted in pre-drilled holes on a large sheet of plywood. Each sheet would then need to be repeated to build up an array of sheets. Any help would be much appreciated.

Hey guys!I'm looking to build an automatic putter with a solenoid from a old starter motor and some super capacitors.I've figured out how to triangulate the distance using a servo and a pair of lasers but I'm at a loss on how to charge them and the math behind it to make sure that the right amount of current goes through.The basic plan is to either wire up a series of the caps listed above and hopefully charge them in series. OR buy a car booster pack and disassemble it for the bits and pieces. OR use a lipo like this and hope that the discharge is enough to hit the ball down the course.Any thoughts or suggestions on some reading meterial?I'll be doing an instructable at some point and will give some cred to the best answer

Since both adapters simply supplied 12v to the prongs, can I replace the adapter with a 12v 3a one while keeping the original cable?
