01:06 rue_shop3 it properly detects the pulse polarity and debounces the inputs
01:06 katsmeow-afk can i have it for free, a working physical model?
01:06 tsmeow-afk j
01:08 katsmeow-afk except for the analog input, didn't Riff do that with his sterio boat weedwhackers?
01:08 rue_shop3 not that I'm aware
01:08 rue_shop3 I have a scenario where I need to detect two buttons over one pair of wires
01:08 rue_shop3 so I'm using AC and diodes on the buttons
01:08 katsmeow-afk turn knob, motors sped up or slowed down?,, oh, his used steppers to move the gasoline throttles?
01:08 rue_shop3 two optos by the micro paralleled backwards
01:09 rue_shop3 then it goes into an avr which reports which input activated
01:09 rue_shop3 1,2,3,4
01:09 rue_shop3 4 buttons on 2 pairs
01:10 rue_shop3 across about 150' of building
01:10 katsmeow-afk oh
01:12 rue_shop3 I was going to use relays and diodes on the avr end, but thought about it and realized that optos take less current and have an inherint diode
01:13 katsmeow-afk and, are faster, and don't need debouncing
01:13 rue_shop3 the buttons are mechanical
01:13 katsmeow-afk so is a relay
01:13 rue_shop3 source of all noise
01:13 rue_shop3 yes, good point
01:16 tsmeow-afk ponders rue making code for a attiny to simulate every electronics part, and building a circuit out of only those avrt
01:16 katsmeow-afk this is an attiny "resistor", this is a "capacitor"
01:18 Tom_itx rue_shop3, did you see that isolator?
01:41 rue_more its an S-rex, it predates the t model

13:21 katsmeow-afk need any wide scsi 4.3GB hdds? i can get armloads of them for maybe $1 each, they are used
16:13 rue_more $1 ea? can I sell them for 50cea, cause I have a lot of them
16:15 rue_more I wonder if there's a motor in there I could use for my truck
16:15 rue_more think I'm aiming at 80hp
16:15 rue_more in something an S10 can hold up

21:01 TELunus Any experience with pulseaudio?

21:18 tsmeow-afk is pondering electric land
21:21 katsmeow-afk so what if you simply ignored the leaks in your underwater robot, and used the waste heat of the machinery to pump that water overboard?
21:26 katsmeow-afk if the internal space of the robot was brought to 1/2 psi above the outside water presure, leaks would be minimal, pump needs would be minimal
21:42 tsmeow-afk wonders, if in the future, floating around on their cities to enjoy the optimal weather, the humans who lived on land ever considered the alternatives to being inundated with flood, snow, ice, drought, high heat, or forest f
21:44 tsmeow-afk wonders if starting with a square 2 miles on a side, and building up and down a triangle shape, would let 500,000 humans have 1000 sq ft of private space, and still allow enough public and work space for happi
22:09 katsmeow-afk re McDonalds : In all, the company serves almost 70 million customers a day spread across 36,000-plus locations. In 2014, such feasting equated to revenue of $27.44 billion�more than the gross domestic product of about 90 individual nations.

23:46 katsmeow-afk rue, what sorta air-to-air or air-to-water or water-to-water heat exchanger can i make using 1mil cellophane?
23:46 katsmeow-afk or is it hopeless being that cellophane is biodegradeable?
23:47 katsmeow-afk i ask because it's tougher and stiffer than poly film sheets, and being thinner it should be a better exchanger
23:53 katsmeow-afk did anyone realise a seadoo is 8ft long?
