01:05 PM rue_house: after that pwm circuit I'm stoked to work on other rediculusly simple complex circuits
01:08 PM rue_house: human brain?
01:08 PM rue_house: think I can do it in 20 transisotrs?
01:08 PM rue_house: I'll think on it
01:10 PM SpeedEvil: The human brain can be trivially done in under 20 transistors.
01:11 PM rue_house: I came up with a great neuron design, I need to play more with it
01:12 PM rue_house: I'm excited to play with the PFM stuff I'v drawn up sometime
01:12 PM robopal: that was what Tilden was trying to do, if i recall?
01:13 PM rue_house: I wonder if I can switch out the 555
01:13 PM rue_house: thats a name I'v not heard in a long time
01:13 PM rue_house: I have copies of docs they took offline
01:13 PM rue_house: back in '89 or so
01:13 PM rue_house: er... 98
01:15 PM rue_house: interfacing nervous networks to computers
01:20 PM robopal: do you have the book, Fast, Cheap and Out of Control?
01:21 PM rue_house: heh no
02:23 PM SpeedEvil: http://imgur.com/gallery/VlIFG
02:23 PM SpeedEvil: Walking Machines Other Than The AT-AT
02:36 PM robopal: machines for specific job, I agree
02:36 PM robopal: what's with that bike with legs
02:36 PM robopal: https://scontent.fath2-1.fna.fbcdn.net/v/t1.0-9/18765890_1746336278715316_9157464198721366681_n.jpg?oh=a7b3c335b62abbbe2132c02de43e1d2d&oe=59B9496D
02:36 PM robopal: would you?
02:37 PM robopal: :D
02:37 PM robopal: "if you get me that bike, I would!" hehe
03:33 PM rue_house: did you know that things been around since like 75?
03:38 PM anniepoo: rue, if you make a neuron, reduce it to silicon and make a massive neural net chip.
03:38 PM anniepoo: 8cD
04:18 PM Tom_L: rue_house, i think you could duplicate _some_ human brains in less than 20 transistors
04:19 PM robopal: :p
04:25 PM rue_house: your right, I could start with, say a Trump and work my way up to the brain of a large fly
04:26 PM Tom_L: he is really rather educated
04:26 PM rue_bed: I'm sure he knows what side the fork goes on
06:46 PM * anniepoo desperately tries to remember which side the fork goes on
07:13 PM SpeedEvil: Prongs into the food.
07:15 PM * anniepoo tries to lay place setting with sporks
07:25 PM * anniepoo lays a table with a vegetable peeler, a wire whisk, and an olive fork at each place
07:36 PM malcom2073: Sounds legit
07:56 PM anonnumberanon: <rue_house> your right, I could start with, say a Trump and work my way up to the brain of a large fly
07:56 PM anonnumberanon: :0
07:56 PM anonnumberanon: 9/10
07:57 PM anonnumberanon: i wonder how many neurons a bee has
08:05 PM anniepoo: hang on
08:05 PM anniepoo: happen to be chatting iwth a biologist
08:12 PM anniepoo: Insects typically have many small neurons. As a top of the head estimate, I would guess between 5,000 and 10,000 in the CNS.
08:12 PM anniepoo: retired Bio prof
08:12 PM anniepoo: 8cD
08:14 PM anniepoo: drawing laser cutting file
08:19 PM anniepoo: Alright, I was under by a lot- Wikipedia says 960,000
08:19 PM anniepoo: (bio prof)
08:20 PM anonnumberanon: it's crazy how small neurons are
08:20 PM anonnumberanon: is it smaller than the smallest transistor chain that can synthesize a neuron?
08:29 PM anniepoo: jonlieffmd.com/blog/the-remarkable-bee-brain-2
08:31 PM anniepoo: Bees have approximately one million neurons in 0.5 mm
08:31 PM anniepoo: not sure what that means, if that's some weird way of saying linear distance or cube or what
08:37 PM z64555: linear distance, 0.5mm is the distance on a slide or tissue under test
08:37 PM z64555: I think
08:40 PM anniepoo: so neurons would have to be 0.5 nanometer
08:40 PM anniepoo: that doesn't sound right
08:41 PM anniepoo: CO2 is 232pm
08:41 PM anniepoo: so if it's a cube
08:41 PM anniepoo: then 5 microns
08:41 PM anniepoo: (100 per side)^3
08:42 PM anniepoo: that's about right
08:42 PM anniepoo: 1 micron tech, a couple transistors. But the bee's 3D, silicon's 2D
09:50 PM anonnumberanon: what?
10:05 PM anniepoo: the bee has neurons in a 3D space
10:05 PM anniepoo: the IC has similar sized neurons in a single layer
11:36 PM rue_house: the ali express login hates it when you finish typing your password before the page has loded
11:54 PM Jak_o_Shadows: irc in the shed
11:54 PM Jak_o_Shadows: truly, this is an age of marvels
