11:29 AM rue_mohr: milled the indicator hole in the face of the cnc yesterday, the orig paint didn't adhere properly so it all started flaking off, had to strip it and repaint
11:29 AM rue_mohr: I was sad I couldn't maintain the logo
11:53 AM rue_mohr: locating parts on that gigantic cnc must be interesting
12:40 PM aandrew: rue_mohr / polprog (or anyone) -- any interest in these: https://ibb.co/LrB5yC6 https://ibb.co/T2xYshr
12:40 PM aandrew: https://ibb.co/FXX1k8Y
12:41 PM aandrew: there is a shitload of (old) DSPs, EPROMs and Z80-somethings
01:12 PM polprog: omg, cards
01:12 PM polprog: ill gladly take them
01:12 PM polprog: always wanted to build a card based system
01:17 PM aandrew: polprog: no problem, I will get dimensions/weight. I'm happy to give them away but will need you to cover shipping
01:18 PM aandrew: gonna do more cleanup/reorg, there may be other stuff you might like. I did find a Coldfire BDM which I think you'll find useful if you are using that Arnewsh coldfire dev board I sent you before
01:21 PM rue_mohr: oo neat
01:22 PM rue_mohr: I think I'm good, what are the analog devices chips?
01:22 PM rue_mohr: adsp?
01:23 PM rue_mohr: PCM line interface, interesting...
01:24 PM rue_mohr: phone system?
01:24 PM rue_mohr: aandrew, I'm looking to shim my stock of 2716 if you encounter any
01:25 PM rue_mohr: Hmm, a set of the 1M ram chips would be nice for that video card project...
01:26 PM rue_mohr: 551001
01:26 PM rue_mohr: polprog, could I get in on one of the sets of ram chips?
03:39 PM aandrew: this was part of a phone system tester, I forget when I got rid of the hassis
03:45 PM polprog: aandrew: i can cover shipping, np
03:45 PM polprog: rue_mohr: what ram sets?
04:00 PM polprog: rue_mohr: if you want anything from that set from aandrew go ahead
04:22 PM aandrew: either of you interested in that OMAP devboard or the old (I'm guessing) 56k ISA modem (non-winmodem)
04:22 PM polprog: i have an abundance of isa modems
05:27 PM rue_mohr: ok I put another 6km on the trike, nothing broke
05:27 PM rue_mohr: yea, I'm good on modems
05:28 PM rue_mohr: polprog, the 551001 is 1M SRAM
05:28 PM rue_mohr: I want to make a video thing at some point, so I'm gathering parts
05:28 PM rue_mohr: pixels stack up quick!
05:30 PM rue_mohr: I need to slow down the steering, narrow the base of the handlebars, and work out some sort of seat suspension.
05:32 PM aandrew: rue_mohr: I'm trying to find some time to play with that beamchaser VGA idea
05:34 PM rue_mohr: there are a LOT of video projects out ther!
05:34 PM rue_mohr: which one?
05:36 PM aandrew: I pasted it here last week
05:36 PM aandrew: basically 100% interrupt driven
06:44 PM aandrew: holy shit I found it
06:44 PM aandrew: my old music tracker player
06:46 PM aandrew: this code is literally 30 years old
06:49 PM aandrew: ; Many many many many many many many (and a few more...) thanks to Karl Wyman,
06:49 PM aandrew: ; who helped humongously with the debugging and general making-it-
06:49 PM aandrew: ; work-ing of TZGUSP. Many hours have I spent arguing with him that the bug
06:49 PM aandrew: ; just couldn't be THERE when that's exactly where it turned out to be... :-)
06:49 PM aandrew: hahahaha
08:57 PM rue_shop2: I took apart the Hybrid vehicle battery packs I had
08:58 PM rue_shop2: charging up one of the cells, its HUNGRY
08:58 PM rue_shop2: its votlage was ok, 7.4
08:58 PM rue_shop2: NiCd
08:58 PM rue_shop2: not sure of the capacity, if I can get it charged up, I might run my charge tester on it, see what I get for Ah
09:49 PM rue_shop2: this new system is really annoying
09:49 PM rue_shop2: I keep bumping my head on custom programs I wrote that aren't installed yet
09:59 PM Tom_L: maybe you should have a common server for everything
09:59 PM rue_shop2: i do
09:59 PM rue_shop2: I just dont have all the apps in one place
09:59 PM rue_shop2: I forget what they all are on acocunt I use them so much
10:06 PM Tom_L: i got stuff scattered all over the place
10:06 PM rue_shop2: well I never did merge my two file servers
10:08 PM rue_shop2: so, javascript has an interesting solution for a problme
10:08 PM rue_shop2: talking to serial devices,
10:09 PM rue_shop2: its an issue if your waiting for a reply to continue
10:09 PM rue_shop2: so they have a special function that does a callback when the reply finishes comming in
10:09 PM rue_shop2: I wrote a function called "converse" but its not *quite* right
10:11 PM Tom_L: wait or timeout...
10:12 PM Tom_L: or wait forever
10:12 PM rue_shop2: I have 43 of these 7.2V NiCd car cells
10:17 PM rue_shop2: one of my cnc tasks is to devise a bracket to move the spindle driver box from the back to the side of the machine
10:18 PM rue_shop2: need to fold a rather large piece of sheetmetal to get what I want
10:18 PM rue_shop2: even if I had a normal box break I dont think I'd be ok
10:18 PM rue_shop2: oh ohoh oh
10:18 PM rue_shop2: so, I was trying to sand blast something last night
10:18 PM rue_shop2: blaster kept plugging up
