Un de- ăsta? Sunt okay oamenii ăștia, a luat ceva mai mult de o săptămână de când am plasat comanda până când am primit Voltcraft-ul, dar totul a mers foarte smooth.

Am studiat putin cazul in legatura cu heliu lichid.
Problema cu el e ca vine direct din italia in butelii la presiune mare pt ca la noi nu exista fabrici de separare si lichefiere.
Pt a putea fi scos sub forma lichida din tub la presiune ambientala sunt necesare reductoare de presiune de care nu dispun prea multi pt ca nu prea e lume e interesata de heliu ca agent frigorific din cauza pretului mult mai mare ca al azotului
Unde ati fost si au zis de 20 de euro pe litru? ca poate reusim cumva sa facem rost

voi studia cazul mai in profunzime si revin cu detalii
L.E. : din pacate la un pret mai rezon nu se poate face rost la noi. oamenii cu baloane cumpara heliu la un pret de 16+ euro cand cumpara la butelie presurizata de 8 sau 10 litrii.

L-am inaugurat pe "cel nou". Nu pot sa trag concluzii dupa o singura sesiune de PI32M la 5GHz cu 1.58v, trebuie sa ajung la ceva 3D-uri mai suparate pe LGA 1366 peste 5GHz ca sa ma obisnuiesc complet cu el. Oricum, din ce am vazut astazi, imi place, merge bine

Pentru cei ce nu-si permit sau nu au posibilitatea cumpararii unui F1, Koolance vine in ajutor:

Pentru cine nu isi permite un F1 avem baietii aproape care trimit oricand pot de CPU pe la 120-150 Euro. Ala de la Koolance e o porcarie.

Pai iau azot sa ma uit la el sau cum.... ? Daca vreti vin la unul care are tub si testez si dewarul. Dar sa testez dewarul doar de dragul de a testa nu are sens.
Se ocupa niste oameni priceputi la el si nu-mi fac probleme ca o sa fie unul performant. M-au asigurat ca pana la pensie ma tine fara problema

Cine crezi ca te lasa sa te apropii de el cu o bomba .... ?!

A colleague of mine forwarded a copy of an accident report from Texas A&M. It seems that in mid-January they had a bit of a blowout there, thanks to a big liquid nitrogen tank. Now, liquid nitrogen cylinders are normally fairly benign, as long as you don't freeze your external organs off with the stuff or leave the liquid sitting around where it can condense oxygen out of the air. But idiocy will find a way - note the regular cylinder on the right and the new, improved model next to it.
These guys are usually equipped with pressure relief fittings, since nitrogen does tend to want to be a gas, and gases do tend to want to expand quite a bit. This tank, though, which seems to have been kicking around since 1980, had been retrofitted by a real buckaroo. Both the pressure relief and rupture disks had failed for some reason in the past, so they'd been removed and sealed off with metal plugs. You may commence shivering now.
Why it didn't blow long ago is a real stumper, but presumably people were taking nitrogen out of it quickly enough to keep things together. Not this time, though: at around 3 AM, things came to a head as the internal tank (these things are double-walled) expanded until it pressed against the outer one. That kept it from expanding anywhere else except on the ends, and as fate would have it, the bottom blew out first. The engineer's best guess is that this took place at around a 1200 psi load. It must have been quite a sight, although it's a damn good thing that no one was around to see it. I'll let the engineer's report take it from here:
The cylinder had been standing at one end of a ~20' x 40' laboratory on the second floor of the chemistry building. It was on a tile covered 4-6" thick concrete floor, directly over a reinforced concrete beam. The explosion blew all of the tile off of the floor for a 5' radius around the tank turning the tile into quarter sized pieces of shrapnel that embedded themselves in the walls and doors of the lab. The blast cracked the floor but due to the presence of the supporting beam, which shattered, the floor held. Since the floor held the force of the explosion was directed upward and propelled the cylinder, sans bottom, through the concrete ceiling of the lab into the mechanical room above. It struck two 3 inch water mains and drove them and the electrical wiring above them into the concrete roof of the building, cracking it. The cylinder came to rest on the third floor leaving a neat 20" diameter hole in its wake. The entrance door and wall of the lab were blown out into the hallway, all of the remaining walls of the lab were blown 4-8" off of their foundations. All of the windows, save one that was open, were blown out into the courtyard.
No one seems to have heard the celebrations, but someone noticed that the building's water pressure had gone a little wimpy and went to investigate, which I'll bet was a real eye-opener. I get the impression that they're still trying to track down the Mr. Fix-It who inadvertently rigged the tank for takeoff. The company engineer who came in to investigate noted that he's seen these kinds of "repair" jobs before, generally after they've powered through something.

Am zis sa-l premiez pe Triplu_Z pentru tot ce a facut pentru lab501 si am facut schimb de tuburi. Inca de prima data cand a vazut fostul meu tub de cupru s-a indragostit de el si am zis sa nu le distrug frumoasa lor poveste de dragoste.
Acum eu sunt noul posesor al tubului ZZZ.
Astept sa fie gata dewarul si apoi am sa rog pe cineva priceput sa ma invete cum sa izolez f bine si apoi sa ne apucam de joaca. Multimetru digital profesional DT-9208A a fost comandat.
