I used c channel aluminium and folded the felt double and pushed 4 inch nail into it . Very tight fit otherwise you can get hot spot very easy . I will be covering mine with clay and sorell cement mix . Also you can get ready made brick to absorb the heat for long heat store . Maybe make sand battery if you put sand on top
@@cayrex I will do a video in next week of sand heater with carbon . I have some already but I have finalised design and will not be using graphite coated sand as it's better to use welders blanket carbon felt which can go over 1000c degrees . The pan felt can not go very high but is ok for 200 c degrees I think . I was getting hot spots and it's very messy with graphite coated sand .
@@Buzzhumma I heat the graphitic carbon felt for 9 hours on 500 deg C. The Activated carbon felt I heat on 900 deg C for several hours,... but have higher resistance as graphitic carbon felt. The carbon coated sand I try allready which works great but because of the little bit higher resistance I need higher power to run
Thanks for the great video. I have some questions, though! What does the pad exactly called? If I buy fiber welding blanket would work as camping pad? What about the woven carbon fiber from Amazon? Does it be better
Will this work with "carbon felt" or do you need to use "graphite carbon felt"? Does carbon felt have the same resistance? I've noticed the price is quite a bit less and I need to use quite a bit of it for my project to melt the ice off my solar panels.
@@AJolly You can buy some 1 or 2 mm thick felt. Finger heaters are nice idea because my fingers are cold in the winter time. But some heated fingerless gloves I already make some videos
@@cayrex How are you controlling both the voltage and the current? I bought a new power supply but it was load dependent. I could set the voltage but I couldn't set a fixed current. Can you please help me out with the type of the current regulator or power supply and how can I overcome this problem? Ithink i am not getting results because the current is so low and I cant force it to be higher. Thank you
In addition, the carbon fiber mat I am using has much higher resistance around 500 ohms and it depends on the length of the sample can go up to 7000 ohms.
@@bobhafi281 You have a felt with to high resistance. Search for graphitic carbon felt on ebay or amazon. Because for high resistance material you will need higher voltage that can operate on a certain current.
Could you set this up to use 120 volts which will really lower the amps and have the added advantage to use up to 15 amps safely and really make a true heater ??? Please give your idea on my idea SIr ?? Nice video too. vf
What is this material called? I think he's saying graphite but I don't know what else he's saying. The closed captions say graphitti. Graphitti cover fat graphittical effect. What in the world?
@@cayrex graphitic - how did you get this name. I am using it a lot to make wicks and smal eletric heaters. It is called graphite felt, carbon fiber or graphite carbon felt. I was trying in google "graphitic carbon felt" but it gives me zero results(except just two scholarly articles for "graphitic carbon felt" written by chinese people - judging by their names) and displaying a lot of graphite or carbon felt. Check it out and accept the mistake, it is no big deal ;)
@@mrtyupratiksha Oh yes sorry, my mistake I make some gCN thos days and for this reason it was associated to graphitic. It is called graphite carbon felt aka graphite felt. Most known graphite felts are based on PAN and Rayon.

Yes using clay & cement is also good idea to use it. Similar I made with my ceramic IR heater. Sand battery with carbon heater,.... interesting 🤔💡😁

@@cayrex yes o found the best grapite was the mold release cheap stuff which was suprise but also very fine sand made it best conductivity
Fantastic! ANy thoughts for a suitable flexible electrode material vs. aluminum plates?
Thanks for the great video. I have some questions, though! What does the pad exactly called? If I buy fiber welding blanket would work as camping pad? What about the woven carbon fiber from Amazon? Does it be better
It is called PAN based graphitic carbon felt. The welding blanket will not work. I dont know about carbon finers from Amazon
how much power did you use for this plz?
Can you directly connect the Carbon felt to the power supply?
You can. But you need to be sure that you have good contact between to the entire width the felt.
Got an electroconductive tip for you.
The black window silicone sealer is electroconductive.
I just don't know how conductive or resistant it is.
Yes I have one graphite carbon silicone. The resistance is in kohm
Will a box cutter or ordinary scissors easily cut through 5mm carbon felt ?
Yes you can cut through carbon felt
Will this work with "carbon felt" or do you need to use "graphite carbon felt"? Does carbon felt have the same resistance? I've noticed the price is quite a bit less and I need to use quite a bit of it for my project to melt the ice off my solar panels.
I can't understand what the heating element is, it says graffiti cover fat in the closed captions? Also says Karma felt heater?
Thank you 👍
Hahahahaha. It is graphitic carbon felt
@@cayrex nice 👍 thanks
Is it possible to find thin ribbons of this? I'm trying to make heated fingerless gloves, just to keep my fingers warm (pip/dip joints)

can it be used not for heating but for cooling effect as well? The material?
Graffiti carbon felt?
He says 'graffiti.' Americans say 'graphite.' its graphite carbon felt, aka magic wick, aka forever wick, aka charcoal felt sheet, aka carbon felt wick.
This is very interesting, Are you able to control the heat produced by limiting the voltage and amperage? Thankyou ☺️
Yes for sure. That is how every heater works
a PWM (pulse width modulator) from a scrap newer car will easily control the power (12Volts, 5A) so you don't need the expensive power supply.

What type of tape?
Kapton tape
Which ir Thermometer you using ?
It is a VOLTCRAFT ir thermometer
Why use PAN graphitic carbon felt and not carbon fibre weave?
Because I have tons of that stuff
You can also use AC and water.
Hi is graphitic felt heats when we apply AC voltage?
Yes
@@cayrex cool ,thanks Dusan
@@bubbatt77 No problem
Bit where do I find graffiti Carmel feds
I said in the video. on ebay
Sorry the black stuff is called what? I tried searching it on ebay but I think I have the wrong spelling
PAN based graphitic carbon felt
I wonder what kind of homemade battery could power that?
The one which will produce around 50W of power 😊 To make more power you need buger surface area
Pan Based Graphite ______ Felt ? What was that word to search the products?
Pan based graphitic carbon felt
good experiment...

Put that in a pail of sand and you would have a cheap sand battery
