Calculate Resistor for Heating Wire

Hi there, My Goal is to use a piece of heating wire from an old hair dryer  (1.6 Ohms resistance for the length i want to use.) and heat it red-orange using my old USB power bank. 5V output from an 3.8V lithium ion battery i dont want to mess with the circuitry inside. Problem: The USB Power Bank has short curcuit prevention built in, so when i connect the heating wire the power bank stops supplying electricity. I found a 7.5 ohms resistor and connected it aswell, the wire became a little warm, the resistor incredibly hot but most importantly the power bank continued to supply power - success. I would like to know what resistor i should use to get the wire red-orange hot but at the same time keep the power bank safe and not overwhelm it - i think that would mean not drawing too much current? I also cant check how much current is flowing because my multimeter is too cheap and only goes up to 200ma, which the power bank exceeds. So how would i go about this? What resistor should i use for what wattage should it be rated. And since im a total newb id like to hear your train of thought as to why and how. Thank you so much.

Best motor and switch for this swinging arm?

I am trying to make the following: i need a 4 foot arm to swing parallel to the ground at a fulcrum. Only needs to travel 90 degrees one direction, then back 90 degrees to its original spot - Kind of like 1 windshield wiper running parallel to the ground the weight of the arm plus load at the end is roughly 10pounds this would be triggered by a single button thats the gist of it. Now if. I could tweak it... i would like one press of button A to move the arm 90 degrees then it stops. A second press of button A would move the arm back to where it originally was.  Or, if this is too costly, I could hold the button down while the arm cycles 90 degrees and back, releasing the switch when the arm reaches its desired location I need cheap options or at least a good place to start. I have zero coding or electronics knowledge thank you

how to use LDR as a relay for RC car to increase voltage to motor

Hi there,  I would like to know more about how LDR's work, its quite difficult to source 3 volt relays in South Africa, so I had an Epiphany, why not use 2x  LDR 1x for Forward and 1x for Reverse on an RC car, I don't know much about how responsive the solution is, how many seconds or milliseconds delay  there is? Does it work like a switch?  would it be a viable option on an RC car?

DC Motor Stop and reverse for a feeder

Hi, I attempting to design a feeder that will raise and lower an access door to where the feed is at. The door will open at dawn and close at dusk. I am trying to design a setup similar to an automatic car antenna. When enough light hits the photocell, the motor engages, travels a distance or hits resistance and stops. When light is no longer strong enough, the motor engages in the opposite direction and after the same distance or it meets resistance, stops again. Is this possible to do without Arduino as I am trying to keep this cheap? If so, what do I need and how can this be accomplished? The photocell is not a requirement as I have seen astro timers that can adjust for the changing sunset and sunrise times. Please help.

What lubricant to refill a fridge compressor with?

Hey all, I just grabbed a compressor from a fridge that had been badly mangled by a bulldozer at a demolition site, planning to make a vacuum pump or airbrush compressor (or both!) Trouble is, I thought the liquid it contained was leftover refrigerant, and drained it all out. I didn't really have a choice, as leftover freon was gassing out of the compressor (thought it had lost pressure, but there was still a little in the compressor) and it was sputtering the oil everywhere. I held it upside down while carrying it home, and when I got it here, it was apparently empty. Then I found out that what I poured out wasn't liquid freon, but actually vital oil that keeps it alive. The compressor runs fine, but I only tried it for a few seconds for fear of destruction. I have many lubricants here, motor oil, 2-stroke oil, bike chain oil, etc. If I'm to dump an oil into my compressor, any ideas on which is the best call, and roughly how much should it take?

Solder sucker?

Hello all.  I had a question about desoldering.  First thing is that I have desoldering wick.  I found out I was using it wrong.  I melted the solder and then placed the end of the wick in the melted solder.  But I watched a youtube video and according to that I should place the wick on the solder and then heat up the wick and solder as one.  But this still has not been working very well for me.  The wick is over a year old and I was wondering if this could be a problem.  But my other question is how well do those spring loaded solder suckers work?  I was thinking about perhaps ordering one off of e-bay.  Yes I know I might find one in a good hardware store but I have some paypal money I could use.  In case you do not know what I am talking is the spring loaded suckers where you cock it, put it next to the melted solder and then press a button and it forms a vacuum and sucks up the solder into it.  I think I can pick one up for a few bucks off-line, so if you people say they work well then I will give it a shot. Also in case you want to know what I am working on.  This would be used for salvaging parts of of circuit boards.  Like right now I am trying to salvage a few capacitors and also a couple of flyback transformers from crt computer monitors.  Also tomorrow I am tearing apart a broken water cooler to see if there is anything I can take out of there. I have also being having a problem getting solder to melt in the first place.  But that probably just has something to do with the 2 soldering irons I am using and I am trying my best to figure it all out.  I know my way around computers as far as building and repairing them.  But soldering and desoldering is something I really want to learn to be able to further my computer repair skills.  Sometimes it would save so much money being able to solder and desolder myself.  Especially those darn ac ports that are soldered right onto the boards sometimes. I have not actually made anything from this site yet.  But this is a wonderful site and after cruzing the forums here I am pretty sure I will get some good replies.  Ok I will stop babbling and I look forward to your replies.

Monster battery pack for pedalboard

Hi! first of all happy being here in such a full and interesting community. Since some time i have an idea fix, i would like to play guitar in the street, not for the sake of money but for pure entertainment. Following that intention i´m being gathering all equipment i need for that purpose. I was asking myself the question about power source for all that stuff. Actually i can make it easy, since i already bought roland cube street, that runs on 6 AA batteries. BUT, i guess nobody here likes easy things. Therefore here is my project: using acoustic guitar with 4 effects and the amp running on the SAME external battery pack. short description of the project : 4s4p battery pack for a total of 14,8V and 12 000 Mah more or less.. will depend on cells themselves. Theoretically it will mean 10 hours or continuous run with all of equipment. of course there will be step down converter and other bells and whistles that i will be happy to share once i start doing it. Questions mainly are : I know that Boss pedals have center negative connection, What the hell does it mean? please someone help with this cause im getting mad. Is it just inverting the leeds? positive one going to the sleeve and negative/ground to the pin? OR it means that the pin has to be  minus 9V? This is the main question as i dont want to burn 200 euros pedals second and less important one: i will mostly go with NCR18650GA units. And will arrange a balanced pack. As the charging rate is 1A rough it takes 3,5 hours to charge. If the total capacity is 12 amp as i'm planning will it be neccessary to wait 12 hours to charge it or 4s4p scheme will still need 3,5 hours to charge all of cells at the charge rate of 1A, can i also charge it at faster rate as cells state that discharge rate is10A and so i coud use up to 10A charger? Or maybe the smart chargers identify by themselves the best charge rate? thank you in advance please know it's my first project of the kind :D

Recording digitally with an analog camcorder

I recently came into possession of a mid-eighties Newvicon analog camcorder. It has RCA outputs for the video and audio (mono), and I'd like to record the output from this camcorder as digital. The idea I had initially was to use something like a Flip video camera (in order to keep it portable), but then I realized that the Flip doesn't have an RCA input... in fact, nothing I know of has an RCA input, unless I wanted to plug it into a computer or a DVD recorder, which negates the simplicity of it recording to a video file that can be dragged and dropped onto my desktop. The reason for wanting to salvage this camcorder and use it instead of just using the Flip is because the video quality is incredibly "eighties" - the color is slightly askew, and the sensitivity to light means that moving the camera suddenly causes ghosting, which, to me, is desirable for the look i'm going for. Personally, I find it fun and interesting to use old things like this instead of the new stuff. The only drawback is the simplicity (or lack thereof) in being able to post things immediately in this digital YouTube age. I'd like to keep it portable. I'd like to keep it simple. Any ideas on a camcorder, or even a "digital go between" that would record onto an SD card or USB drive? Does anything like this exist? If not, I'd like something like an SD card go between, as I have a 32 GB SDHC that would work great for this kind of project. This is the same model camera - the video outputs are located on a proprietary PSU, which isn't a problem for me to carry around, or have plugged into an extension cord.

Orange pi's 3.3V on board regulator

Hi everyone, I've set up a mediacenter with openelec on my orange pi PC. I've put a large heatsink on cup and rams and a small 5V 0.15Ah cooling fan. With two switches I am able to switch it on and off and choose between 5V or 3.3V alimentations from the GPIO. The 3.3v is intended to spin that fan not at full speed to reduce noise while watching film or listening to music with the mediacenter. I left the PC all the night open downloading torrent, and the morning later the fan wasn't spinning anymore. I powered off the system and used a day later. The fan were at that moment working. So my question are: Is it better to put an external voltage regulator (lm317)? Anyone can explain what happened? As I recently discovered that with zener diodes we are able to clamp the voltage to a specific value (if putted in the "opposite" direction, I guess), I was thinking if it were possible to use one of them in this case.

What is the best way to dim AC LEDs

I was wondering what is the best way to control a AC load with a Arduino. I am planning on building a Christmas lights display that will react to music that is playing. I would like to be able to control the rightness of the LEDs to. I know that Triacs are normally used to control AC loads but I've read that they supply inconsistent dimming. Another idea I had was to use a bridge rectifier to turn in to dc, then use a Mosfet to run it at like 10% duty cycle to avoid blowing the LEDs (Not sure if they could take the extended time under high load they might be subjected to). Then just increase or decrease the duty cycle to adjust the brightness. So all in all my question is will that work and is there a better way to do it.

LED Strip Arduino

HI All, This might be a simple thing, but I am in a big of a Maker bubble and dont have anyone to call up and ask this question to. I have an arduino that I want to hook to a LED strip, THe thing is i dont know much about power and how to measure/ know you wont fry your stuff and Im worried that I might do that. So, I am coming to you to ask. Would this work?
