01:19 AM rue_bed: I need to work out a chime for the driveway sentry
01:22 AM rue_bed: I should also work on getting an avr playing an audio clip
04:43 AM Luminax-Work is now known as LuminaxWk
04:43 AM Jak_o_Shadows: What's a good rigid body library?
04:44 AM Jak_o_Shadows: Or rather, blender's version of bullet keeps jittering crazy
05:29 AM squirrel is now known as veverak
09:18 AM rue_more: zhanx, I think I could makea 2 stroke into a hit and miss by having a valve around the carb thats left open during the compression stroke
09:22 AM zhanx: rue_more: i think i said hit and miss before
09:23 AM rue_more: you did, I was thinking
09:24 AM rue_more: the mix ratio of a gas engine is about 13:1?
09:24 AM rue_more: fuel air?
09:25 AM rue_more: or is that the compression ratio
09:25 AM rue_more: 14:182 psi
09:25 AM rue_more: ? hmm
10:34 AM SpeedEvil: rue_more: probably more sane to do it by adding fuel injection
10:34 AM z64555: engines mentioned?
10:34 AM z64555: !clog
10:34 AM z64555: err
10:34 AM z64555: !zlog
10:35 AM z64555: .zlog
10:35 AM z64555: sigh
10:35 AM z64555: .clog
10:35 AM z64555: alright I give up
06:13 PM anniepoo: @zhanx, you around?
06:13 PM zhanx: yes i am, just sat done
06:15 PM zhanx: anniepoo:
06:15 PM anniepoo: hey
06:15 PM anniepoo: So, made a version of blender file suitable for your use
06:15 PM zhanx: cool and thank you
06:15 PM anniepoo: but wondered if you wanted the eye stalks
06:16 PM zhanx: nope I can make those thank you
06:16 PM anniepoo: also, need you to email me annie@theelginworks.com with your addy so I can ship it
06:16 PM zhanx: was making beer today and both my brew buckets started leaking, it was almost bad
06:17 PM anniepoo: I'd suggest making them yourself, the layered cardboard doesn't handle small off-axis 'stalks' well
06:18 PM zhanx: sent
06:18 PM zhanx: I figured that
06:18 PM zhanx: and i had an idea on them
06:19 PM zhanx: gonna custom make a linear to servo horn for them
06:35 PM anniepoo: sorry, work distraction - what do you mean?
06:44 PM zhanx: its a thought right now is all
06:45 PM zhanx: but use 2 servos to move them around like some of the octopus tentacles
06:59 PM anniepoo: soft robotics -
07:00 PM anniepoo: 3 rubber tubes, silicone or latex, syringes pushed in and out by servos
07:01 PM anniepoo: (use a large syringe and shorten it to reduce stroke)
07:05 PM anniepoo: I could probably do the eyes at about the point you're ready to do yours
07:05 PM anniepoo: so maybe we can just make two sets
07:22 PM rue_more: I have to try making air muscles from the silicone tubbe I got
07:22 PM rue_more: but I dont know if the tube I got is thin enough
07:23 PM rue_more: its hard to find really thin silicone tube from china
07:23 PM rue_bed: anniepoo, your aware of the 3d printed moulds for castingsilicone actuators?
07:24 PM anniepoo: no
07:25 PM rue_bed: oh
07:25 PM anniepoo: I've seen a video of a guy doing just that
07:25 PM rue_bed: hackaday silicone actuator
07:25 PM anniepoo: he's 123Adrain or something
07:25 PM anniepoo: yes, on hackaday
07:25 PM anniepoo: he's 123Adrian or something
