I'm a fan of brutalism.
<alexisvl>
yeah. he meant it as a compliment and i received it as one :)
<qu1j0t3>
i'm definitely feeling compliment vibes and now i want to see your boards.
<tunixman>
me too!
<alexisvl>
hm i should show my previous rev crt controller but i don't have that layout handy
* alexisvl
has been leaning more "curvy" than "brutalist" lately tbh
<tunixman>
hahahh yeah... I feel that for sure. sometimes I like curves, sometimes I like edges, metaphorically.
<tunixman>
that came out badly
<alexisvl>
haha
<qu1j0t3>
yeah i've seen your curvy ones. mods asleep, post pcb pics any time
<qu1j0t3>
oh i'm not sure i knew about your blog. wow, i might learn a lot here.
<qu1j0t3>
this is stunning
<qu1j0t3>
new goals unlocked <3
<qu1j0t3>
I _did_ get 1kV regulated working
<qu1j0t3>
then i put it aside months ago to work on the vector gen.
<qu1j0t3>
efficiency was poor though. i was using Baxendall self resonant. as I know you do in one place.
<alexisvl>
haha i constantly forget to update it
<qu1j0t3>
at first i got 80% efficiency and then only half this and never pinned down why, over weeks of struggling
<alexisvl>
next post will probably be a big writeup on the frontend, which is still pretty early (going to send out pcbs today or tomorrow)
<qu1j0t3>
<tunixman>
oh! You're the person doing the oscilloscope from scratch!

<alexisvl>
yeah i'm that dumbass
<tunixman>
hahaha hardly...
<tunixman>
it's a wild ride doing that sort of thing.
<alexisvl>
heh yes. i was in college when i first decided i wanted to do it. now i'm 30 :p
<qu1j0t3>
this vector gen took me 4 years from sketch to pcb.
<qu1j0t3>
for Various Reasons (life events mostly)
<alexisvl>
yeah there was a lot of Life in there
<alexisvl>
somewhere between deciding to make an oscilloscope and having half of one scattered around my bench, i got a degree, conned someone into giving me a "senior engineer" title ;), moved halfway across the country and found a new gender just lying on the floor to be picked up~
<qu1j0t3>
:)
<tunixman>
heh, 30, damn.
<tunixman>
t qu1j0t3 how many relationships ago was I haha
<tunixman>
alexisvl: that's rad, very rad
<alexisvl>

all I did was burn through friends and family.
<alexisvl>
oh i did that too
<tunixman>
yeah...
<tunixman>
you did that and more
<tunixman>
is what I mean
<alexisvl>
lol
<tunixman>
I guess I did have two kids of my own but my wife did most of the real work there.
<qu1j0t3>
tunixman: We need to get you back in the hacking mode. or musical mode.
<tunixman>
we do, yeah... I'm planning some basic electrical work on the house now. I want to bring it up to code at least.
<tunixman>
it wouldn't be out of character for me to add some basic hall effect sensors to things and get live current readings.
<qu1j0t3>
talk to asjackson about this
<qu1j0t3>
he has done this for his house
<tunixman>
I mean I do work for an IoS team.
<tunixman>
I'd probably just throw it together myself with some weird cheap high I/O pin board...
<tunixman>
I now have a blowtorch and two nice vintage workbenches.
