Thank you for sharing the design and testing process. It helps us beginners understand and learn quicker.

As mentioned in your other video I think your project is a great service to the DIY community. Many retro computer and reverse engineering projects are faces with older EPROMS and serial EEPROM programmers are mostly unable to read them. If you ever redesign the PCB my suggestion is to have all the jumpers and links on the exposed side.

Thank you :) I like to help where I can.

Looks good. UV lamps are something you don't want to sun tan with. I have your 65uino kit. Looks great. I have been busy fixing up/ Cleaning up this room. I like it nice. I am a bit of a neat freak. I enjoyed this video, and I wont star at any UV lamps.

I think it’s a great project 😊

Regularly in Finland school kids and others make bird nesting boxes. Looks line your UVC enclosure with an extra hole.

I think the school children might take offence with that statement :D I'm really not proud of my box - but at least it works.

Maybe adding metal foil tape onto the walls of the wooden box would make erasing faster by also reflecting light that would otherwise not hit the chip

And/or the lid too. Good idea!

nice work .. I have since tested the cheap phone sterilizer and it works too .. the positioning of the chips is a bit awkward but with some blue tack it works fine

That's actually surprising, since I assume they have UV LED's - which are crazy expensive in the

@@VVerVVurm Ah! I believe I’ve seen those tubes too, those should work just like this - but the first many results from the markets show LED versions .. which I guess are also less effective at their advertised purpose.

I've built my eraser using a T8 UV lamp - whatever was able to find. But now I can erase ten EPROM simultaneously 😅 Also, when you erase UV EPROMs - always short all the leads together (e.g. using a piece of foil). UV light induces a current (photoelectric effect) which may damage the chip

@AndersNielsenAA 14 күн бұрын

Yup, I've noticed the T8's - actually I could've just replaced the tubes in my "UV-B" lamp with those but this was... somewhat insignificantly.. cheaper :) Wouldn't shorting all the pins make it worse - letting current flow where it doesn't belong? My logic can be very flawed. I wonder why the datasheets don't mention this.

@@AndersNielsenAA All UV erasers I have ever seen had conductive foam in the tray. I think the risk of photoelectric charge build up will be low. Shorted, resistive or open pins will probably all work fine.

Thanks for the insight - I didn't really have much experience to go on for this little project.
