My first gas portable - the "PortaHeNe"

i tried getting pix of my spots with my cam. i have a real one now, but i guess i need to learn photography too (it never does end, does it . i can't seem to get any detail of the multimode aspects of the spot from my known mm tube. it's similar to the vids, but less random, tighter. looking at the spots of the little tube and the mm side by side tells me i was wrong about the mode of small tube. thanks for the nice vids:beer:

wow! Nice Build. I'd still consider that portable though :crackup:

Interesting idea!!
Really... your idea seems contagious and is inspiring others!!
Portable gas laser... hmmm...

I saw some plans for an I2 ion vapour laser... IR anyone? interesting project?

+1 Very neat pattern from your tube btw, Multimode?

very schweet... 2 thumbs up!

Very good work! It's beautiful!!

This is the best thing i ever seen!
