... Wrong wavelength; you may as well leave them out in the sun for a few days/weeks. When they say UV, they *mean* UV. -- Dave...
The BC "blacklight" globes will not erase an eprom. AFAIK they need a light source in the "microbiological" light frequency. Suggest you google it for more...
Hi Troy, Steve, et al. I made the same mistake many years ago. I bought black light fluros for erasing eproms. Suffice to say you need a much shorter wave...

I believe that it was either Jaycar or DS Electronics that had a tooth brush steriliser that was great for erasing UV erasable-EPROM's. It was quite...
In addition to my last reply I offer this URL in relation to the JARCAR tooth brush steriliser that can double as an EPROM eraser. http://tinyurl.com/lhhhl ......
Just had a memory come back to me;-)(bad acid flashback?;-) It has been said by some that the UV toothbrush disinfectors (check ebay) can be modded to erase ...

One warning everyone, The UV from these shortwave UV tubes is very dangerous. It is not like the long wave UV from 'blacklight" tubes which is basically...
I guess there will be a lot of cheap FM900's and scanners on eBay soon ? I wonder if the garbled voice is a fault in the digital system, or wether they just...
Looking at the short wave light has been described as being similar to arc welding without a helmet - sunburn to the eyeballs is not good! p.s. don't put any...
Whatever you use, the wavelength needs to be less than 300nm (250nm recommended; x-rays will also work!). The saying goes that if it won't cause sunburn then...
I can confirm that glass is a bad decision! I decided to do the 'week in the sun' trick, but of course, didn't want any water issues, so I put the eprom in a...
Hello all, Some time ago I came accross this article http://www.siliconchip.com.au/cms/A_104058/article.html while I was looking for a solution to erasing...

As long as you state that your FM900 is ACA compliant and is set to 5w power output, Ebay will not remove an add for an FM900 programmed to UHF CB. k101oz...

Mark, or anyone! Do you know anything about the glass used in cheap scanners (computer type). I am experimenting using my EPROM eraser UV tube to expose...

I would imagine that the glass in scanners is standard glass, perhaps hardened. Going by the Wikipedia entry on UV, only a little light capable of erasing...
Yep, about 70 - 80% of UV radiation is absorbed in standard window glass, clear plastics are similar. Quartz is used in the production of UV lamp tubes...
If you specify that buyers must have an amateur license, then, at least as far as i have seen, you should have no problems - eBay are only protecting...
Thanks for all the replies about glass and UV. I suspect that glass may vary in its UV absorption. In photography it is common to fit a UV filter to the lens...
