12:00 AM smellsofbikes: But wow does it hold heat well if I'm doing a multi pour.
12:07 AM smellsofbikes: those shots of what looks like a carbon mold are very nice.
12:07 AM smellsofbikes: Oh, yeah, I just got to the shot of you making a top very much like mine.
12:07 AM smellsofbikes: Sorry. Yo get kinda a travelogue as I go throgh the slides.
12:09 AM rue_mohr: those carbon molds, are actually steel ones form Tom_L
12:10 AM smellsofbikes: Whew. That's some CNC to be cutting steel that size with that nice a finish.
12:10 AM smellsofbikes: Okay. I should head to bed. Thank you for all the ideas.
12:10 AM smellsofbikes: sleep well when you do.
12:10 AM smellsofbikes:
12:10 AM rue_mohr: :)
12:12 AM rue_mohr: oh I should be drying more clay when I do the castings
12:14 AM rue_mohr: maybe I can open back up the mining tunnel to the (new) underground hidden shop
12:14 AM rue_mohr: as its the only way I might get some space in the next 20 years
01:09 AM rue_bed: need to mix more casting sand
01:09 AM rue_bed: need buckets to put it in
09:43 AM rue_mohr: hmm what regulator should I put on this cpld board....
11:55 AM splyne is now known as spline
08:32 PM aandrew: what's it need
08:34 PM Tom_L: 5 iirc
08:35 PM aandrew: there are plenty of nice 5V switchers with excellent regulation
08:36 PM aandrew: sweet, my son booked a christmas movie, I go with him on set for more or less the rest o the month
08:36 PM aandrew: it's up north (North Bay)
08:51 PM rue_shop3: 3.3
08:51 PM rue_shop3: for some reason this --XL PLD is 3.3
08:59 PM rue_shop3: aandrew, cool
09:06 PM aandrew: it's very rare to find 5V programmable logic - they do exist though, but are not mainstream
09:19 PM aandrew: well
09:19 PM aandrew: I have a feeling I'm going to be up all night
09:19 PM aandrew: I've been fighting this for the better part of three weeks now but I keep slipping more and more late
09:19 PM aandrew: last night was 4am and that's usually the point where I decide whether it's worth trying to force myself to go to sleep at a normal time or say "fuck it" and get this over with
09:27 PM rue_mohr: hmm
09:35 PM rue_shop3: ok I set up that trigger in the high temp silicone
09:35 PM rue_shop3: let it set up for... a few days
09:36 PM Tom_L: making a mold?
09:37 PM rue_mohr: gonna try it
10:24 PM aandrew: wtf
10:24 PM aandrew: these connectors I ordered off of ali and paid for crazy shipping were delivered today... to bangkok...
10:25 PM rue_mohr: hmm, is that worth a refund?
10:25 PM aandrew: yes
10:25 PM aandrew: I asked them to look into it
10:25 PM aandrew: but I kind of need those damn parts
10:26 PM rue_mohr: not sure if I shouldn't just drop some linear regulator on this for the 5V->3.3V (cpld board)
10:27 PM aandrew: it's worth a try, I kind of doubt the CPLD is doing anything seriously fast
10:27 PM rue_mohr: no, tho I'd like to put a 100MHz osc module on it
10:27 PM rue_mohr: using the dip14 version so it can be socketed
10:32 PM aandrew: try a linear and make sure there's decent bulk and bypass capacitance near the CPLD, but it might not be sufficient
10:33 PM rue_mohr: I'm just gonna see what it eats, but I keep getting distracted
10:33 PM rue_mohr: https://www.st.com/content/st_com/en/about/events/events.html/stiso-isolated-interface-webinar-ame-2021.html
10:33 PM rue_mohr: ^^ distraction
10:34 PM rue_mohr: 20:20:31 up 106 days, 15:09, 0 users, load average: 1.75, 1.28, 1.05 <-- I have a lot of windows open
10:35 PM rue_mohr: I have 24G of ram sitting beside my computer waiting to be put in on the next reboot
10:35 PM rue_mohr: its dusty
10:36 PM rue_mohr: It is comprised of 16 54V18 Function Blocks
10:36 PM rue_mohr: ""\
10:36 PM rue_mohr: thats an interesting thing to say
10:37 PM rue_mohr: yea, this thing can eat up to 525mA
10:38 PM rue_mohr: as low as 125
10:38 PM rue_mohr: 125 probably meets minimum for a switcher
10:39 PM rue_mohr: not sure why I cant get a jtag answer
10:39 PM rue_mohr: there will be a crazy-small smps chip, hmmm
10:51 PM aandrew: rue_shop3: tell me about distraction: https://ibb.co/bsvm3s4
10:51 PM Tom_L: is it a different jtag protocol?
