Homebrew heaters using resistors?

Hello, First time poster! :) I've been reading up on some projects on this site centered around small homebrew heaters. One I came across I want to adapt is using two resistors and usb port power to make a small coffee mug heater. I'm kind of a novice at electronics, but I'd like to know how to design such a heater with safety and functionality in mind. I also want to control this heater via arduino if I can get a prototype together. Some questions I have: Where to get and what kind of resistors for heaters? How do I figure out what resistors to use based on power. e.g. 12v or USB power? What's a good thing to "encase" the resistors with that will withstand heat? I have thought about using radiator repair epoxy. Thanks for any help!

Miele washing machine - tripping the electricity (RCD)

Hi I have a Miele W5741 washing machine which is three years old. The other day it tripped the electricity (RCD) I found that it would trip the RCD every time regardless of what program I used. After a few trials I have found the following: if I use the machine and select cold water (no heating of water) then it does not trip the electricity (RCD). So my conclusion is that it is the heater that is causing the washer to trip the electricity! What do you think? I opened up the front to locate the heater. However I don’t see how I can remove the heater as I see no screws! I have attached a pic so you can see the front/heater.

Heating for outside battery storage compartment.

I have an idea for a wind powered outside LED light for the family's cabin. It would be on a pole and illuminate the pathway, just like a street light would do. So I wanted to have a battery in a box with my wind turbine charging the battery through the day and night. The problem is, it gets really cold sometimes like -36F / -38C and that would kill the battery. So, I also wanted to include some really small, simple heater inside the box. I'm having problems finding anything on what would be the best way to go about this. Wikipedia says heaters are made by resisting current. Are there special types of resisters you add to your DC current to create heat? Thoughts, suggestions, feedback are all welcome. Thanks.

diy pool heater

I have tried so many different ways to heat my pool water and have had little luck. One way I did it was to take about three hundred feet of black 1/2" drip line and run it around the pool rim. I supplied cold water from a smalloutlet attached to the return line,using the power of the filtration pump to move the water from the pool through thecoil and I adjusted the flow to about half of the normal, then at the end I had the heated water re-enter the pool. Iwould say the water got to about 100 degrees, by the time it went through the drip line. The problem is that it wasn'tefficient enough to have any real effect on the pool water temperature which stays at about 60-65 even on the hottest days. I live in the Sacramento area of California, and we get pretty hot summers, usually about 90-105. Any suggestions on how I could make this idea more efficient? My pool water temp is always too cold to swim in, and I have a capacity of 12,000 gallons.

Heat storage device for car cabin heater

I want to increase the heat storage capacity of the existing car heater so that I can run the heater (just the fan and a liquid pump) while the engine is off and so I can have a warm car as soon as I start on a cold day. The current heat storage is the coolant circulating in the engine. I want to increase the capacity of that. Instead of simply attaching a liquid reservoir to the heater circuit (to increase the coolant volume), I was considering using a picnic cooler (insulated) box with a coper tube coiled in it. The box would be filled with oil and paraffin. Paraffin melts ≈ 40° C  and I can take advantage of the latent heat of fusion when the paraffin changes phase. The oil is a medium to suspend the paraffin. I need a recommendation of an electric 12 volt pump to circulate the fluid. I request any other thoughts or criticisms.

Space Heater Repair, is there a glue for broken heating element coil spacer that is inflammable? Answered

Usually a space heater consists of a fan mounted to a motor which is then mounted to a back plate. Connected to the back plate are reflective spacers that hold the heating element coils seperate from eachother so they don't spark. Recently, I figured I'd repair my space heater after it started sparking instead of going and buying a new one. I opened it up to find the spacer plate which has several arms for holding 1-5 coiled wires. One of the arms was broken and the coils touched which is why it was sparking. Seeing as this is a heater, i'm fairly certain I can't use a super glue or epoxy to fix the plate due to its flammable nature. The plates are not easily replaceable themselves as they've been spot welded into place. So the question, is there a type of glue which will hold up under high temperatures which is not flammable that will bond metal / plastic / ceramic. I'd estimate the heating element probably reaches no higher then 700 degrees. If you have any suggestions on how I would go about repairing this I'd love to hear your ideas. Thanks in advance.

Need help diagnosing my non-working gas wall heater.? Answered

Hello, I live in Arizona so we just tried to use our gas wall heater for the first time tonight (hasn't been necessary before now).  This is the type of heater we have installed in our hallway/bedroom. http://www.homedepot.com/buy/williams-monterey-50-000-btu-natural-gas-top-vent-wall-furnace-5009622.html#.UJ-qvYaElhE I lit the pilot and then moved up to the thermostat that is mounted on the wall.  I moved the dial from the left (which starts at 50) over to the far right (which stops at 90).  I felt and heard the thermostat click over at about the 65 degree mark (which seems accurate to me), but nothing happens.  Usually, immediately after the thermostat clicks over, the gas flow increases, and the heater starts to do its thing. I have included some pictures of the thermostat, and heater itself.  If someone could tell me which connections I need to check with a volt meter, it would be greatly appreciated. One thing I want to add, we had a light socket go out on the same wall about a month ago, that doesn't seem to be getting any power.  I have tried several new bulbs and it doesn't work.  So I would need to figure out how to check if the thermostat is even getting power as well.  It's possible that the thermostat isn't even getting power. Thanks SOLVED:  Thanks everyone for your replies.  It actually was the solenoid inside of the heater, but the good news is it works fine, a wire just came loose.  Everything is working great now.  I wouldn't have thought to look there if it wasn't for your comments.  Thanks again!

USB heater

Hi everybody! As sais in the title of the topic, I want to realize a USB heater. Let me introduce you to what I think. Last week, I was in the store near high school with some friends, and one of them told me : "It would be cool if we could heat up things in high school, to have like a mini oven directly in our locker, working with battery." Of course, the idea is not to install a oven in our locker, firstly because it would need an incredible battery, and secondly because it would be pretty dangerous.... So here is the idea : the goal is to heat up at least 2 chocolate breads at 60°C. The heating time is not very important, but it has to be under 40 minutes (a system will start the oven before our break). But here is not the most complicated : the oven has to get its power from a usb power bank(I can plug in 2 power banks if necessary). To conclude, I have to fin a solution to heat approximately 1.5L,( but most of it is filled with air), at 60°C, with a power of a maximum of 20W. I saw things to heat coffee by USB, would it work if I take the heating pad? Also, I would like to know how much power I can  get from a power bank (in W), before it to heat too much.

Peltier Cooler/Heater - Pooling Brainpower

I recently acquired a thermoelectric mini fridge. As a fridge, it doesn't work so very well - it will get down to ~50 degrees with an ambient temperature of 70. So, I took it apart. You know the saying: "If it ain't broke - fix it until it is." So I now have a peltier effect cool/heater. I put my meat thermometer on the cold side with the fan off - and it gets down to freezing (probably a bit below). On the hot side, with a big sink and fan - it seems to be ~85 at it's warmest point (this sink is about half a square foot and an inch deep). Ideas on where to use? It's 110 service.... It literally almost killed me a few days ago when I touched a transistor sink that was part of the rectifier circuit while holding a plate that was grounded (I got knocked out for a few seconds) I've got a couple ideas, I just figured I'd pool brain power and see what happens :p
