Most Greedy Boy, of them all... or (there is no) DEFiSIT of Papa's Koans
Default Most Greedy Boy, of them all... or (there is no) DEFiSIT of Papa's Koans

Most Greedy Greedy Greedy Boy (of them all)

Yup , that one would be Me , Mighty Moi , ZM

What’s the Catch ?
Nothing …. except here’s the story ……



Culprit : I was constantly bugging Papa about mostly everything , squeezing both question and answer of 42 ….

Consequence : so he in one moment (certainly desperate move ) came to idea that bribe is the way to cope with me ……..


(Fact: Papa is naive ; Do not tell him that simple e-mail addy block is more than sufficient to solve all his ZM related troubles…….. though if he really start using that , we’ll have mass suicide of DiyA Papaland members ……. sometimes I have an impression that e-mail traffic to Pa is almost big as regular posting on forum )


So – he asked me what do I want , from pretty extensive list of things , he’s working on lately;


As usual , I said – nuttin’ , frankly not needing anything , being 2 (3, 4, 5) years late in things obligated (from various reasons) to build for my self …..
But – after repeated reading of his proposition , greediness started getting better of me , and I asked him for few more words about DEFiSIT ; when he replied , I instantly had impression of (my absolutely fave) M2 , with heavy twist(s)
so ……..
now – few pics from recent BAF....... Papalecture , DEFiSIT simple , DEFiSIT no values , Real MCKay one and two , little more detailed schm.

Aha ....

Lucky me ..... crystallization moment of entire ( taking advantage of naive gift giver) operation , was when I realized that I had opportunity of my personal Pony Express executive being in USA and soon going home …… with possibility to fill some space in luggage ;
So , I got finger (not that one !) , pulled entire arm ,and result is - nice FW box , arriving at Pony Express rider temporary address :

as agreed ....... what was really agreed is DEFiSIT kit , in most beaten FW case , as we know that Papa is using them for all sort of prototyping .....

well , he tricked me - case isn't beaten at all .....

as I said - Kiddoe is handy with Allen key ;

per my instructions - everything is dissmantled in pieces , for better usage of suitcase space and for lesser amount of Customs curiosity , at arrival home ;

approach resulted fruitfully - Roentgen in Customs is still cleverer than operators

few days ago I started assembly/disassembly/assembly ;

Reminder : Assembly of Japanese bicycle require great peace of mind.

PSU pcb is obviously (same as in BAF specimen) from (early?) testing/production of SIT-1 ; and - Pa obviously used that pcb for some tests , and few power resistors in CRCRC are not same in channels (yup , dual mono PSU) ...... lucky me (again) , if not brain , I have great piece of mind , so I spotted that ...... also one cap per channel used in other purposes , now connected to other ones

just from habit - my fave Philips 1uF MKC , as bypass on C1 and C2 position

did I wrote that Papa sent all caps in bubblie ?
....... more precisely - all parts , except small metal films

I also changed C2 to (also) my fave (125C , so industrial?) ELNA 470uF/35V

Ok , Donut time ;
He sent me schmtc , but he didn't wrote about rails value ; after several emails (yup, me bugging again) , I finally got that name of the game is PapaSit's sweet spot ...... so set voltage and SIT will sit in proper current



Donuts- I have them zillion years , never had some use for them , until now

potted , shielded ; had to drill bottom Donut all through (careful with that Axe, Eugene .... it's easy to make a short , so drill bigger hole in shield pan on top)

50Vct , so CT going to GND on PSU pcb , while start and end of secondary are connected to just two diodes of Graetz bridge , routing neg to neg PSU input
