=Basics=
*A [[Kiln]] that uses wire-resistance based heat to reach and hold a set temperature
*Can also be used as a metal melting furnace, but this is not reccomended (outside of mettulurgical chemistry, and "special" use cases neccesitating it's use) due to it's innefficiency
*Used mainly for:
**[[Heat Treating]]
**[[Firing Ceramics]]
**Drying Chemicals (in batches for labs etc)
**Chemical Reactions Requiring High Heat (but not [[Open Source Tube Furnace]] level, or as a lower cost option)
*It is a relitively inexpensive device to build for a shop/makerspace/microfactory, and the capabilities it provides make it almost essential

=Industry Standards=
*

=Existing Open Source Designs=
*[ One of the Main Projects of the [https://www.youtube.com/channel/UC3dmgnqBSqlENPwPcxZ33Cw/videos Youtube Channel "Paul's Garage"] has been such a device
**Unlike others however, it is high quality, and has other functions such as gas injection for an inert, or reducing atmosphere
**This, plus their documentation seems to make this the obious option

=Minimum Viable Product
*
*[[Firebrick]] lined inside sealed with [[Firebrick Mortar]] for longevity
*Common Tube for use of an inert atmosphere, or a reducing gas (but this is an option, but perhaps install the tube anyways for ease of upgradability?)
*Arduino controlled for complex heating cycles, and gas managment
*Display of current temperature, desired temperature, and perhaps time left? (simple display, 7 segment even)
*Temperature probe

=Basic Design=
==Shell==
*Essentially a sheet metal (powder coated?) exterior to hold everything together and add some durability/regidity
*Perhaps a "ledge" below or above for all the electronics etc

==Lining==
*[[Firebrick]]s cut to size in the desired box size
*[[Firebrick Mortar]] to seal the gaps

==Heating Coil==
*nicrome wire?

==Gas Inlet==
*What type of pipe?
*Use hole saw to drill, through a top (for downwards flow? does this matter?) firebrick
*Add either a cap and insulation, if not in use, or a manifold for inert or reducing gas

==Control Unit==
*Arduino
*Custom Sheild?

==Power==
*[[Universal Power Supply]]
*Can this perhaps replace the control unit too?

==Display Unit==
*Either a few [[7 Segment Display]]s, or a cheap lcd/e ink
*3D Printed Holder
*Label either with a labelmaker, or with perhaps incorperating the labels into the 3d print (celcius/farenheight marker, what the gauge represents etc)

=BOM=
*

=CAD=
*

=Code=
*Somthing like octoprint but for kiln heat profiles, that and/or a simple knob system (for simple ones) and an sd card (for complex ones especially with gas)
