I had one of those erasers! I think standard procedure is that the first one they send is a broken one and the second one they send is intact! Was in my case anyway! I gave mine away when I discovered that I could get EEPROMS to use in my projects rather than deal with all the UV erasing.

Just took delivery of my one of these today. Bulb was intact thankfully. Timer is just crap. Might have to make some sort of electrical timer so I can just press a button and it'll go off when I expect it to.
Yeah, you've got to open it up, it's an unwritten rule. They are handy things when you need them, but spend most of their time gathering dust. These are a great price for what they are really. Does the job.
@@backofficeshow Yeah I just bought 20 16Kb EPROM's for Amstrad stuff. So will be handy. Might buy more ROM's for future games I might write...if i ever learn ASM properly.
Would you suggest avoiding staring into them? :) If I recall they are radically different from black-lights. I guess they are on the other end of the UV spectrum
@@backofficeshow The tubes are usually around 253nm, which is quite a short wavelength. I think some of the common UV LEDs only go down to about 315nm, and EPROMS need that specific lower wavelength to erase in any reasonable time. I tried even leaving some out in the sun once, and they didn't erase a single bit, even after about two weeks. lol Either way, LEDs are generally way too slow... charlesouweland.wordpress.com/2017/12/28/improvising-an-eprom-programmer/

OK, I now WANT one of these... ruclips.net/video/_sSuzDg4ntA/видео.html I thought about using a flash lamp before, but never knew they actually made such a thing for this.
Apparently, it's the "Quick-EII eprom eraser from ZAX Corp", but I can't find them atm. Looks like just a standard small Xenon photography lamp, though. Don't think it would be too hard to just make one from a photo flash unit.
@@AaronHuslage AFIAK China uses the same plugs as Australia, the ones with the angled connectors. And while US and Japanese plugs are technically compatible the sockets are different and the voltage and current are incompatible unless the device itself accepts a range of different voltages, its 100 Volts In Japan, 120 US and 220-240 in Europe.
China actually uses two types of plug. 2 prong US style, and 3 prong Australia type for things that require an earth connection. Power outlets in China accept both types.

I have the same eprom eraser. So does everyone.
The mains cable is super thin.
Worked fine for my Amiga EPROMs. Burnt AmigaOS 3.1.4 just last week.

It's definitely a unit that needs to be monitored 😂 Eeproms are a lot simpler but I can't seem to find them in large sizes

@@electronraygun6346 have you seen any 64k or 128k ones? I'm interested regardless of package

Is that current meter supposed to show anything when it's turned off ? ;)
I'm not even sure it works 🤔

Did you loosen the timer? I know if it is misaligned it can bind up
@@backofficeshow I've not done anything with it yet other than cook some greasy chips. I did open it up because... well that's what you do right?

Neat. I find sometimes with rom chips they can be a little hit and miss on the programming so having an eraser is super handy.
Those clear UV tubes are reasonably hazardous to your eyes and skin.

I was about to buy one of these but after i watched this video i decided to build one. Might be a bit more expensive but not a crap like this.
How did you build one? Did you follow a project one the web, or go from scratch?
You don't really need a mechanical timer, it's mainly just a lamp in a box
Isn't that one of the electric plugs China uses?
Not sure, never been, but it's definitely used in the USA
Yes. That’s the predominant plug in China and Japan as well as the US

He will not pin this.
Absolutely correct! 👍
