This reminds me very much at my own computer: http://www.retrocom.de/cgi-bin/weblog_basic/index.php?page_id=107

BTW: My PC is broken since a couple of weeks, so I'm actually using it currently!

I like the Retro look to it looks like a little valve tv very good work ! have you made cases for you nbtvs ?.....desk top computers remind me of having a mini refrigerator with tons of wires coming out of it must be one of the most ugly things ever invented !

Least laptops do away with most of the wires .

Yeah but when something breaks they are pretty much unrepairable, and, most importantly, their parts are less salvageable for NBTV stuff!

Oh yes and i have done that a few times laptops are very hard the little hard drives are still good to scrap .

Because things are getting so small there will come a time when we run out of mechanical parts vcrs are gone computer will go all solid state in time ...i can see that to do our hobby in years to come they will have to remake all the parts as in the 20's and 30's ...i wonder if the electronics will be a problem too they may stop making parts apart from things like an now a ic phone or ic tv with little or nothing to scrap ? a sad day for us scrap yard hunters .

Of course I always make a casing for my mechanical TVs, here are some examples:

Very good Doctor Z something about wood and electronics thats much nicer than Plastic !

Your much better at wood work than me ,i hadn't seen these before thanks for posting .

[DrZarkov]

Thank you, but you are better in electronics!

[Harry Dalek]

Thank you, but you are better in electronics!

I will swap you for some wooding skills for electronic ...a hint in doing circuit boards i worked out a while back use as little plastic coated wires as possible
try to cooper wire under the circuit board ,it a maze but neat....rat nest wiring is a no no in my zen zone .

I used to use normal plastic sleeved bell wire for all my point to point wiring on boards until very recently.

I've now discovered the JOY of using solderable enamelled wire. It's so neat! (you do need reasonable ventilation though as the fumes from burning the coating off aren't pleasant)

I use "wire wrap" wire - but then I have a heap of it from a previous life...

Gary, how do you strip the isolation from the wirewrap wire? The teflon tends to be difficult to remove from the thin wire. Although teflon is nice because it doesn't melt on the soldering iron tip.

Klaas, I now use one like the attached image, it does a very good job, but to be honest I have used just about every kind of stripper there is and they have all worked at least to some degree. To be honest though, I wish I had discovered this kind of stripper years ago, it is very versatile.

I prefer the claw kind as they cut the insulation all the way around, though I generally just use my side cutters as I'm too lazy to keep changing tool

Yep, that used to be my stripper of choice but I tire of having to adjust them all the time. These need to be adjusted too but have a much wider range for any particular setting. (actually there are different kinds of "claw" strippers I assume you mean the non-flat type which are much harder to adjust again).

And yes I have used side cutters often when I can't find a stripper to hand, but they don't work very well on the wirewrap - they tend to only strip along the edges you are in contact with and you are left with little "curlies" where there is no contact.
