I’m currently (also) designing a digital logic analyzer with a target maximum frequency of about 100MHz. To cut the story short; I received my “special” parts from SEGOR today. Incredibly I payed about 44€ for these 2 ICs. The first is a Cypress CY7C1347G-133AXC 128k * 36 static RAM; which can take up to 133MHz clock rates (static because I don’t like [and can’t take care of] refresh cycles…). The second is of course the Altera EPM570 CPLD (for up to 300MHz clock). Today these beauties arrived in a quite big box (which made me think of why they send such a giant parcel) but as i unwrapped it… but see for yourself…

I remembered to have a old HeNe laser tube laying around which I got for some bucks some years ago … at the Ham Radio fleamarket. I don’t own a neon transformer so it was pretty much laying ’round without any use. I rediscovered it today and I decided to hook it up to my 15kV (AC) high tension transformer. I used a 1k470 series resistor to keep “power down”. Pics… (klick for high res!)
