COMPONENT SORTING
Now found another drawer... a smaller one this time ! OK, I promise... I think... I am pretty suuuure... I really believe they aren't any more hiding anywhere now, this is the last drawer/box/bag of components that was left to process ! I guess only time will tell if that was a lie or not...
Lots of IC's again ! A whole plastic bag of brand new TO92 things as well.... guess it's all BJT...
A few cool IC's in metal cans with gold plated leads, just as I like them
A few EPROM, love these old ceramic EPROM, they look so cool, and I am always so curious to read their contents, it's like opening a mystery box !
... but that will have to wait for the lab to be computerized and equipped with a chip programmer of course... so not anytime soon. The longer the wait the bigger the excitement !
But that will be for another day... 00H40 here and I am yawning badly.
Good night people....
OK I am done sorting all the transistors in that drawer.
With so many small packages, not knowing if every one might a different type... I tried to speed up the triaging process and instead of putting them all in (temporarily) labeled drawers, which takes time to open and close them hundreds of times, and make the labels... I tried a faster approach. Simply put all the packages oto my A4 notepad, writing on paper directly the type of each transistor... this way takes no time to add a new type, it's compact, and you get a quick overview of what you have, see which ones are numerous and you might want to keep, which ones you have noly one or two or three of and you might want to sacrifice in the name of drawer real estate.
Had to download a few datasheet to learn about the specs of this or that, so I can make decisions on what to keep and what to scrap.
Ended up scrapping half of it. Other half, 50% were types I already had so cool, easy enough to add more to them. Remaining 50% were new types so had to "insert" them in the existing drawers, bit a shuffling around required and made two new drawers, but it was not as painful as I though. However it's most definitely much easier to insert them in the ... spreadsheet, just right click "insert line here" !
They are all BJT, 2N and BC series.
Have a huge pile of BC639 ! They are interesting : small packages usually means small signal transistor, but here no, for a change it's a "beefy" transistor, so higher voltage and current handling capabilities, but much lower gain. 100V and 1A, and low double digit gain.
Also kept the BC307. Their spec is nothing I didn't have already, but there are a significant enough number of them, 10, and they have cool gold plated leads, it's what saved them, didn't have the heart to scrap such beauties...
And for dessert, I noted this one : 2N2369. Somehow that part number sounded familiar, so I Google it and yes, it's the type Jim Williams used for is fast pulser, that every one builds around the world. I sure meant to make one too at some point, so more than cool to have those !
Only 3 of them though, but better than none at all. I am sure there are better transistors these days, but I like vintage stuff and walking in the legends foot steps is thrilling. Can't wait to build that pulser !
OK so now I can move on to sorting all the ICs... stay tuned...
