02:49 AM rue_mohr: aha 2573!
03:23 AM rue_bed: grows too fast it falls
04:28 AM Tom_L: .
09:14 AM rue_mohr: morning
09:34 AM rue_mohr: well, the glue will be set by now
09:34 AM rue_mohr: I have a robot to play with a battery monitor and voice for
09:34 AM rue_mohr: there is the injection molder to fix up and test
09:35 AM rue_mohr: still have the stuff for the 1 bit computer to try
09:38 AM rue_mohr: interesting dream were me and mom went to some tropical islands for a holiday, most of the dream was about cleaning up to come back
09:38 AM rue_mohr: ma found a whole bunch of stuff she wanted to take back and it looked like fitting it in the van would be an issue
02:03 PM rue_mohr: https://www.ebay.com/itm/165467604835
02:03 PM rue_mohr: dont mind me, I did something stupid and someone else did too
03:25 PM Tom_L: goodwill will sell you a shirt ya know :)
03:55 PM rue_mohr: dont care about that, it cost $15 to send
03:55 PM rue_mohr: so, interesting thing
03:55 PM rue_mohr: when you list on ebay.com, 'local' is the usa, so I didn't get my $1 for international shipping for selling it from canada
03:58 PM rue_mohr: er $13
03:59 PM Tom_L: cost more to send it than it sold for
03:59 PM Tom_L: something wrong with that picture
04:00 PM rue_mohr: well, it sucks that I didn't get the $1 for 'international shipping'
04:00 PM rue_mohr: but if I put $13 shipping for simple items, now I know.
04:03 PM rue_mohr: ok I shipped that, got milk and papertowel, set up access for the sprayer bank account, and got the 6-32 square nuts I ordered for the sprayer handles.... like.... 2 months ago?
04:04 PM rue_mohr: so, mowerbot and various yard tasks
04:07 PM rue_shop3: ok, I have to add wires for hardware handshaking to that serial card
04:31 PM rue_shop3: maybe I should have checked this card before hacking it
07:02 PM rue_shop3: I cant get the serial card to work on the mowerbot
07:23 PM rue_shop3: ok low battery detector is working ok
07:27 PM Tom_L: sounds like you're going all thru it
07:29 PM rue_shop3: one of the stress points to using it is watching it for a flat battery
07:29 PM rue_shop3: there is no off, so it just runs the battery to 0
07:29 PM rue_shop3: I try to catch it at 10.5 min, but I have to keep checking
07:29 PM rue_shop3: so I'v added a low battery detector that shuts down the cutter and auto wander and cries for help
07:29 PM rue_shop3: it can still be manually driven
07:38 PM rue_mohr: but apparently its raining, have to wait to test
07:39 PM Tom_L: mmm
07:48 PM rue_shop3: since its raining I can do indoor things and not feel bad
07:48 PM rue_shop3: like this extruder
07:48 PM rue_shop3: get the mowerbot off the bench...
07:54 PM rue_shop3: some kinda M6 thread ok,
08:18 PM rue_mohr: http://ruemohr.org/~ircjunk/tempimage/p1230886.jpg
08:18 PM rue_mohr: backwards, I know, but there is no room to flip it
08:21 PM Tom_L: you gonna insulate it?
08:21 PM rue_mohr: yes
08:21 PM Tom_L: or heat shield..
08:22 PM rue_mohr: I have mineral insulation, but
08:22 PM Tom_L: does the thermocouple go into the tube?
08:22 PM rue_mohr: not sure what to wrap that in
08:22 PM rue_mohr: its up against it
08:23 PM Tom_L: k
08:23 PM rue_mohr: but also in contact with elements on either side
08:23 PM rue_mohr: its a 3 way sandwhich
08:23 PM rue_mohr: oh and I need a ground off that too
08:23 PM Tom_L: not the most accurate but a reference i suppose
08:24 PM rue_mohr: well, its in the middle zone
08:24 PM rue_mohr: the tip should be hotter, as the coils are tighter
08:25 PM rue_mohr: someone who might have known what they were doing and was being overly polite mentioned a hole to know when its full
08:25 PM rue_mohr: sorta a fill confirmation thing
08:26 PM rue_mohr: if its a thing, I might grind a small trace off the back hoof
08:26 PM rue_mohr: will see
08:26 PM rue_mohr: right now I need to extend the element wires and insulate it
08:26 PM rue_mohr: wtf do I put around the insulation tho
08:26 PM rue_mohr: maybe sheet metal
08:30 PM Tom_L: not the antlers?
08:30 PM Tom_L: i kinda wondered about that but didn't receive an ECO for it :)
08:31 PM Tom_L: got some bigger tubing?
08:32 PM rue_mohr: thin sheet metal I'd say
08:46 PM rue_shop3: ok, got a ground wire
08:59 PM rue_shop3: ? I dont have any of the thin stuff I'm looking for
09:01 PM rue_shop3: I can pick some up tommorw, so I'll get the control box assembled
09:05 PM Tom_L: who mentioned the vent?
09:06 PM rue_mohr: someoe on twitter
09:06 PM Tom_L: so they saw what you were doing?
09:07 PM rue_mohr: yea, I been posting progress :)
09:07 PM Tom_L: i kinda figured it may need a vent for the air to escape
09:07 PM Tom_L: but that would also escape between the halves
09:07 PM Tom_L: it's not air tight...
09:07 PM rue_mohr: yea
09:07 PM rue_mohr: thats my thought
09:08 PM rue_mohr: I expect a bit of flash
09:08 PM Tom_L: i'm afraid of 2 things
09:08 PM Tom_L: the ring and the antlers not filling in
09:08 PM rue_mohr: I can get that plastic pretty thin
09:08 PM Tom_L: time will tell
09:09 PM rue_mohr: yup
09:10 PM rue_mohr: I'm curious about what fill speed I can get
09:21 PM Tom_L: how long did it take that blob?
09:21 PM Tom_L: should be rather quick
09:21 PM rue_mohr: fraction of a second
09:23 PM Tom_L: i've seen an aluminum mold working and that took seconds
09:23 PM Tom_L: not pour, pressure
09:30 PM rue_mohr: most of the cycle was probably active cooling time
09:31 PM Tom_L: yeah
09:31 PM Tom_L: maybe have a block of ice handy to set it on :)
09:33 PM rue_mohr: I wonder how much energy there is to the plastic charge
09:34 PM Tom_L: enough to burn your finger if you stick it in the goo
09:34 PM rue_mohr: !....
09:34 PM rue_mohr: should I try it with hot glue first?
09:35 PM rue_mohr: no, I cant load it fast enough
09:35 PM rue_mohr: hmm
09:44 PM Tom_L: the hot glue would probably stick to the mold more anyway
09:56 PM rue_mohr: sorry, energy problem
09:56 PM rue_mohr: I took a B12, but if its gonna work it'll be a while
09:58 PM Tom_L: that helped me alot during covid only i had the shots
09:58 PM Tom_L: i was kinda surprised
