Birtija / pitanje za elektroničare
riknula mi je kartica u laptopu, 3D vise ne radi, a na desktopu su šarene crte,
Pošto se može izvaditi van iz laptopa, pokušao bi sa tom "tehnikom"
Na netu ima x tutoriala, mozda netko ima iskustva ili drugi prijedlog?

Ostalo / T: tokar
traži se tokar, koji bi složio jedan "čep" sa navojem prema uzorku
materijal plastika ili neki aluminij
promjer ca 6 cm i dužina ca 5 cm
ili ako imate nekog za preporučiti u Zagrebu

Elektronika i baterije / baterije storage mode - 2 godine kasnije
turnigy 3s 2650 30-40C
stare ca 4 god
malo napuhnute su bile i prije, prevedeno dosta ciklusa
ostavljene su u storage modu 2 godine
jučer sam ih stavio ponovno na storage mode na punjač
bile su na nešo niže od 11.4
napunio je u jendu 40 mah, a u dugu ca 60mah
i to je bilo to
danas sam stavio jednu puniti, napunjeno 1156maha
ćelije 4,19 4,19 4,18
bile su na suhom uskladištene, a temperatura, manje više kao i da su vani ostavljene, od -10 do 35 stupnjeva C
nisam neki frik za mjerenje baterija i sl., tako da ovo u principu ništa posebno ne znači, osim da možete baterije ostaviti 2 god na miru na storage mode-u i manje više će biti OK

Elektronika i baterije / vijesti iz povijesti - Hedy Lamarr - Frequency-hopping spread-spectrum
Između snimanja filmova i preko nekoliko brakova, gospođa je imala vremena učiniti nešto što će danas avio modelarska populacija znati cijeniti
Although better known for her Silver Screen exploits, Austrian actress Hedy Lamarr (born Hedwig Eva Maria Kiesler) also became a pioneer in the field of wireless communications following her emigration to the United States. The international beauty icon, along with co-inventor George Anthiel, developed a "Secret Communications System" to help combat the Nazis in World War II. By manipulating radio frequencies at irregular intervals between transmission and reception, the invention formed an unbreakable code to prevent classified messages from being intercepted by enemy personnel.
Lamarr and Anthiel received a patent in 1941, but the enormous significance of their invention was not realized until decades later. It was first implemented on naval ships during the Cuban Missile Crisis and subsequently emerged in numerous military applications. But most importantly, the "spread spectrum" technology that Lamarr helped to invent would galvanize the digital communications boom, forming the technical backbone that makes cellular phones, fax machines and other wireless operations possible.
As is the case with many of the famous women inventors, Lamarr received very little recognition of her innovative talent at the time, but recently she has been showered with praise for her groundbreaking invention. In 1997, she and George Anthiel were honored with the Electronic Frontier Foundation (EFF) Pioneer Award. And later in the same year, Lamarr became the first female recipient of the BULBIE™ Gnass Spirit of Achievement Award, a prestigious lifetime accomplishment prize for inventors that is dubbed "The Oscar™ of Inventing."
Proving she was much more than just another pretty face, Lamarr shattered stereotypes and earned a place among the 20th century's most important women inventors. She truly was a visionary whose technological acumen was far ahead of its time.
