Do-it-yourself thermal paper

Hello,I am thinking about buying a small mobile printer, but the smallest (500g/1lbs, €50) available is using thermal paper.While I could find the paper rather cheap in the US (from about 6 cent/sheet) here I could not find anything similar.I did stumble across http://www.atarimagazines.com/v6n2/Inventions.html (" ... homemade thermal paper has a darker printout than any thermal paper you could buy. ... Be sure to clean your thermal head ... .") andhttp://www.ehow.com/how_4685502_make-thermal-paper.htmlHas anyone tried it or allready an old thermal printer to try?Even if it will not be suitable for every day use, I am really interested in the subject :-)

Thermal epoxy or Thermal grease and bolts?

I am mounting 15 Cree LEDs to get an old overhead projector to work as a video projector. the only thing I am wondering is whether thermal epoxy is better to use than thermal grease with bolts and nuts attached to a heatsink. Do both have the same heat dissipation? What I am trying to do is still use the LEDs for use with other projects in case i need them for something else.

I need to source a very small thermal switch that would fit beside a peltier and open at approx 50 C. Answered

This is to prevent someone from getting a burn. I was thinking of the small battery cut offs but I do not know if they reset once opened.  The smaller the better as it would be ideal if it was flush with the peltier. I would like to wire it to the power source as a simple mechanical thermostat.  Power supply ranges from 5V, 500ma to 13V, 1A. It needs to be simple as there is no logic board. Thanks, Paul

Thermal insulation/cover for heating water bottle

I am building a water bottle that can heat water inside up to 80 degree Celsius for my engineering project. The design of the bottle is as follows:1. an aluminium or steel flask2. heating coil at the bottom of the flask(for heating)3. battery and circuit for the heating coil is located below the heating coil.I want to design a cover such that a person can hold the bottle when the water is hot. Also, i want to protect the circuit and battery at the bottom from the heating coil. How can I do this? (As of now, i was thinking to spray polyurethane foam around the bottle and use a plastic cover. Also, using a polystyrene board below the heating coil to separate it from circuit board/battery). Are there any other insulating materials that can be used? Considerations for cover and insulation: 1. Should be able to hold the bottle 2. Wash the bottle (hence, waterproof)

If someone can help menu would greatly appreciate it and when i build it I will post the instructions on this site :D Thankyou

Copper tape for thermal concentration

Has anyone ever used copper tape to concentrate heat on an object to obtain a uniform higher temperature?   I've been doing some studies in the recent past that suggest polished copper foil is a good reflector of infrared energy. It is not as good as silver, but I don't think it would go over well to use silver in any sort of oven or kiln.  I used to think good ole aluminum foil was good for heat, but it turns out it is only good for stopping heat.  I've thought of using the instructable on the waffle iron or make one by way of a bread toaster, but will most likely not be able to go through with it.  The copper foil is the same type found at stained glass craft shops.

USB heated Gloves mod Qs

I recently received a pair of USB powered heated gloves. Unfortunately they have a big bulky switch that hangs too closely to your hands and dangles around when you type. I'm looking to mod the gloves to have a less clunky switch, something more streamlined. The gloves have three setting, High (II), Off (O), and Low (I). There's a pic of what the inside looks like. I'm trying to figure out how the circuit works. I would assume it was just one setting is full power and the other has the resistor in it, but the resistor appears to be soldered to two leads on the switch. Does the wiring of it mean it skips the resistor when it's in the high position? Also what type of resistor is that (the big grey type) can it be substituted for a smaller one of equal value? It's not that important, I'm just curious, because I think I'm actually going to make the mod only have the High setting and probably without the switch since I could just unplug them instead of adding in a switch.I think the heating elements might be wired in series because the top pad doesn't get as hot at the bottom (or maybe they're just different temperature pads?).And I'd like to add a battery pack option. What would be the ideal (smallest) batttery setup I could use? (5 volts right?) Would a 9v battery overwork the thermal pads or just make them hotter?I was also thinking of changing the connecttion to a connector like this (LINK) a might be a little smaller, thoughts? Also what wires on the USB are pos and neg?

Thermal conductivity of two welded plates?

I am in the process of building a wood stove (details on FE Blog) mainly from scrap metal, but I have got it into my head that a stainless steel hotplate would be nice. I wanted one 10mm thick, round with a diameter of 390mm. As it turns out 6mm seems to be a bit of a threshold for stainless, and anything over has to be laser cut or similar and is loads more expensive. Like £80 is the cheapest I can find it.  Anyway, one solution would be to buy two 5mm thick plates and weld round the circumference - that seems like it would work out quite a lot cheaper. The question is how would the thermal conductivity be affected by the tiny gaps which would inevitably remain in the centre (the two plates will never be completely flat)? Is there some kind of thermal paste that could mitigate this, which is very heat resistant? If so how would it deal with being superheated by the welding, and would it contaminate the weld? And lastly - this got me to thinking about copper bottomed pans - how do they bond the copper to the stainless steel (google is failing me- or I am failing google with poor search terms)?? So 3 sort of related questions: 1.Welded plate- big conductivity problem or naught to worry bout? 2.Super high temp. thermal past  - would it help? 3.How are pans copper bottomed anyway??

Thermal Cooling and Heating

It is very possible and it is in use today by using Thermal Cooling and Heating from the earth. Performed by using a 6" well at least 100' deep, with thermal tubing inserted into the well carrying the liquid to be cooled/heated. Process is done by a circulating pump in the interior unit - through the coil - sending back through the well system and returning. It starts out from the main unit circ pump.......through the coils.......out to the "down tube" into the 6" well pipe, a sharp 180* turn back up the system returning to the circ pump. Such a system is used by many facilities to Air Condition or heat rooms of about 15' x 15' or so. I have even seen a system that utilized creek water as the "cooler" of the tubing on a circ pump system. That one really was cool, about 52 degrees. Have you heard of these systems or seen something like it or close?
