It turns out that sudo room suddenly has $8,600 in bitcoin! How did this happen? I don't know! I think we should immediately sell at least enough to pay our debt to Omni. Any sudo members who think we shouldn't just sell every single bitcoin right now while the price is high? -- marc/juul

solenoid wanted for sudoroom circuitboard CNC machine

by Jake

does anyone on this list have a solenoid? something that can pull a pound or two of force, from a distance of 1/4" or more, ideally. 12-24 volts would be great, although we could do 120V if necessary. thank you -jake On Wed, 2 Aug 2017, Alexander Papazoglou wrote: > Awesome! > > Any response about the missing solenoid?

bicycles and parts gathering in sudoroom

I don't think people should be using sudoroom as a place to store their vehicles, and large projects like bicycles should not be stored here except for very limited situations like a project that takes more than one day. People have been working very hard on cleaning up the space and the electronics waste pile … [View More]
