Replacement for nichrome coil...

[crip]

My guy says he can do it its 25$ and need the swift code,, and he said most big banks will do it.. too.

but eaiser is to just wire it to a person direct,, he said for thousands of dollars its best to do a to bank transfer..

but for the 250 he said just get his personal name and send to him western union and he can just go in and pick it up with the tracking num somethin like that..

hope that helps if not my friend will do it he will just need swift code n funds ..

Any progress?

We figured out how to transfer the funds (I think - haven't done it yet), and I'm just waiting for him to tell me they are ready to ship. I was hoping it would be today, but it looks like it will be next week.

When he is ready to ship, I'll transfer the funds, and then contact everyone who PM'd me and those who posted interest on this thread (in chronological order) until I have takers for the 10 samples. Hopefully, we can make some real progress once we have them in hand. I've been watching the thread on the glass attys, and that solution looks like it may have promise as well, but given the choice I think I would rather trust a ceramic-encased heating element over a glass one (since I would be inhaling the debris if it broke).

I'll keep everyone posted.

and they do look much easier.. and those ceramic elements have had major testing by me over the year.. they work,, just need to be adapted..

Ok will be waiting for the PM, and I agree on the glass element for different reasons. One of my concerns over the glass breaking is the nichomium is not being cooled in any way, and the life expectancy since it is not in a vacumn like a light bulb, can not be very long. But I guess time will tell if I am right. If you come up short on supporters let me know and I will fund the rest.

I'm interested if you don't have 10 takers yet.

You guys are amazing with these designs.

 

[Quit4myKids]

Thanks, Dan, and everyone else, for the support shown for this. I'm still waiting on the supplier, but it should be very soon now.

All I have to say is...Woo-Hoo and Yippee!!!!!!!!!!!!!!!!!!!!!!

 

[wampumhunter]

Has anything come of this? Did the order come trough? Did it work? Any updates would be great.....

 

[Quit4myKids]

Funds have been transferred to China, and they are attaching the electrodes today. I should have a photo of the actual product tomorrow, and they should be in the mail by Friday from China. As soon as I get confirmation of shipment from China, I'll start PMing folks.

Thanks, everyone for your patience. I wish we could have had more samples, but if we can make them work, I'm sure we can find enough takers for a minimum order.

Thank you, Q4mk!

This might be of interest to you guys. I found a discussion on the German forum regarding this.

Radiation might be a problem... I am no expert on IR.

Translation from website. LINK

The following are in thermal IR emitters emitters (in contrast to diode lasers) understood.
The offer by LASER COMPONENTS comprises reflector of manufacturers CAL Sensors and Intex. All the IR emitters are in TO-supplied housing. IR - emitters are here by user often in competition with special very cheap micro-bulbs. Up to a wavelength of about 4.5 microns special lamps often provide a fairly good level of radiation at higher wavelengths is the use of IR emitters mandatory. It may, however, for 2 reasons even below 4.5 microns to make sense to specific IR emitter should be addressed: To have an IR emitter mechanically robust, and, secondly, there are models that allow electric pulses are very good (sometimes up to 100 Hz).

Emitter of CAL-sensor
The emitters of CAL-sensor (CAL-source) are based on metal alloys. These are either a spiral (SA Series) DC version for unpulsed operation or as a metal ribbon (SVF series, design for pulsed operation), one pair of parabolic mirrors as standard. Used will be a robust and widely proven technology, are possible when no further improvements. The maximum temperature is 730 ° C.
SPF Series
The SPF series of CAL has been introduced to achieve higher speed. A modulation level of 50% is achieved in the new design at about 180 Hz. The lamp with the maximum temperature of 1000 K are available in TO-5 package with an integrated reflector and sapphire windows.
SF Series
The SF series was cheaper than blackbody emitters for applications in the NIR and IR developed area. An ultrathin Metallfolienfilament with an emissivity of 0.88 provides a radiation, which comes close to that of a black body.

Emitter by Intex
The IR emitter by Intex are based on the other hand, relatively modern technologies. It is structured around micromechanically hotplates. On a one carbon-silica nanocomposite membrane (amorphous diamond) as a resistance material is deposited, which has a very low temperature coefficient of resistance, and high emissivity. Special advantages: Due to the short thermal Zeitkostante can be reached at 100 Hz modulation frequency is still a modulation depth of 50%. Because of the constant resistance is observed no Einschaltstromimpuls. The radiator is location and dimensionally stable. At the maximum temperature of 750 ° C (10 Hz, 50% duty cycle) a lifespan of 10,000 hours at 600 ° C. for about 25,000 hours. The core competence of Intex is the special carbon coating. The developers certainly still see room for improvement on maximum temperature and lamp life.

JXMiller, This is interesting stuff, but I'm not at all familiar with the technology. I think it bears additional investigation by someone with some IR experience in a different thread. Have you looked into the technology further? It appears that one of the suppliers listed on the page is a US company.

In any case, it's a good find.

I have a photo of the final heaters, and they are on their way now from China to California.

I'm not interested in making a profit from these, but I would like to cover my costs. Total cost per heater is $25, plus $3 to cover the padded envelopes and First Class postage to the US. If someone outside the US wants one, I'll charge $2 plus the actual shipping cost. If anyone wanted to contribute a little extra for the time I spent, I wouldn't complain (I'm currently unemployed ), but I'm not asking for anything beyond my actual costs.

I'll start sending out PMs tonight to the first ten people that have previously sent PMs to me or posted interested on this thread, and will continue until I have takers for 9 of them (of course I'm keeping one for myself). I doubt I will reach the end of the list before they are all spoken for, but will post here one way or the other within a few days. One requirement for receiving a heater is the ability to test it, and an agreement to post the results to this thread for everyone to see. I really want to encourage the free exchange of information from all concerned.

Thanks to everyone, and let's keep moving forward.

I hope I am one of the lucky winners!
I completely agree to the terms.
That said, my hat is now being flung into the air!!!!!!!!!!!!!
We all win.

anxiously awaiting a PM...

 

[jxmiller]

I am in if you still need someone to test. What the hell.
