A decent unit can be bought from ebay under US$ 50.If you wan to build one, then need to find a UV light first. Purple color UV tubes are available (pettah electrical shops), and you may try it first. I am sure these common UV tubes are not ideal, thus will take a lot longer exposure time to get the data erased.You ideally need 254 nM wave for erasing EPROM data. Sunlight, floresent lights etc. have some amount of this, which can damage the data if exposed. But for a compleate erasure, you need lots of wave.You can do it dirt cheep if you expose the UV window to sunlight, for a week or two. This is not a gurenteed method, but will work eventually.</blockquote>
