00:07 katsmeow-afk i need someone to tell me what is best tooth belt dimensions to connect a 1hp 90vdc 0-3000 rpm motor to a ER25 spindle for general drillpress duty, plus steel, plastic, and aluminum milling
00:08 katsmeow-afk the spindle is 32mm , the motor shaft is 1/2
00:08 katsmeow-afk the motor is designed to make hp at high rpm, of course, but it's pretty torquey
00:09 katsmeow-afk however, if i need to goto 100rpm for steel milling, that's 30:1 and going to need intermediate belt shafts, or a gearbox
00:10 katsmeow-afk i have 3hp on a ~30:1 worm drive box, but i wouldn't expect that to last long
00:10 katsmeow-afk and the ER25 is prolly not designed for that much torque anyhow
00:11 katsmeow-afk but atm, the smallest 32mm toothbelt i find is a 8mm pitch 3mm wide

01:04 katsmeow-afk G5: Currently this question seems rather trivial, but as the technology advances I think it will be a question that will have to be answered. If your creations are alive, how do you handle the ethical implications that arise with this? For example, if Norns are alive, what right do we hold to "play god"?
01:05 katsmeow-afk If a few artificial lifeforms (none of whom are very much alive yet) have to die in the name of progress than that can't be helped. After all, we're killing ants and spiders and monkeys and gorillas and tomatoes and other human beings all the time, essentially through ignorance of whether it is right or not.

07:47 katsmeow-afk the episode in the news at about the guy who shot his computer.... tv news just said he shot the hdd 8 times, not the entire computer , even whils showing the side of the computer with holes fairly evenly spread center of mass
08:40 katsmeow-afk he prolly missed the hdd entirely

15:33 katsmeow-afk i have the tube for the ER-25 mill, the tube that holds the spindle bearings

21:45 katsmeow-afk Over $750 million per year is spent in the U.S. picking strawberries alone. <<== what if they did it together?
21:45 katsmeow-afk In Phase I, $1 million was raised through qualified investors, including seven from the strawberry industry. In Phase II, Harvest CROO is seeking to raise $1.5 million to build the next version, the Alpha unit, which will be the predecessor to a production model. The Alpha will not only pick, but also place the berries into consumer packs.

22:19 katsmeow-afk Noyce's failure to implement his brilliant idea was almost certainly a direct result of Shockley's discouraging comments to him in 1956.
22:22 katsmeow-afk The aluminum film along with the optical nanosensors also display iridescent colors. Because these colors can change according to the angle they are viewed it�s possible to use the film to detect small variations in position and provide a surface topography to whatever its stuck to.

22:54 katsmeow-afk Universal Robots has been expanding at a rapid pace, selling 2000 robots last year and planning to sell 4000 this year, with expected revenue of $100 million.
22:54 katsmeow-afk The UR3 will sell for US $23,000 in the United States. (The UR5 costs $35,000, and the UR10, $45,000). Like its predecessors, the UR3 is a 6-axis articulated arm that can perform a host of tasks (pick-and-place, soldering, screwing, gluing, painting) in close collaboration with human workers.
22:55 katsmeow-afk To program the robot, you can simply grab it, move it around, and tap on a touchscreen to record the desired positions and actions.

23:45 katsmeow-afk i wonder why my capacitor meter is saying these 1000u, 220u, and 100u caps are actually all 80u caps
23:46 katsmeow-afk i gave the meter an olde 47u cap, and it says it's 45u , which is acceptable
23:47 katsmeow-afk but a 80u caps in a larger package with "1000u" on it is not acceptable
