I don't plan to bike commute in the winter, it is too dark AM and PM. Have you tested your LiFePO4 batteries in low temperatures?

Sure if you can't DIY. It's a 20 year old Fuji chromoly-frame mountain bike with Shimano components. My biggest expense was new batteries, followed by heavy duty e-bike brake pads. What did you pay to build yours?

Oh, clearly. But for that money I'd buy a really nice BMW i3 REX. Obviously not an option for everyone.

I am using 3x 12v 185wh batteries in series. Realistically I can count on around 500wh. They are only 3 lbs each and fit neatly within the frame of the mtb. I don't like having them up on the rear rack, they tend to make the tail of th

I just added strips of fake fur to the straps my boring old helmet to diffuse the wind noise the same way a "dead cat" cover on a microphone does. They look a bit like muttonchops which is a bonus as far as I am concerned. I use w

$4500 is ten or more of my homebrew 750 watt electric mountain bike originally built in 2004. I just repowered with LiFePO4 after 10 years in storage and the new batteries really pull. It has a front hub motor with a throttle control limite

My takeaway from this story is that as an (aspiring) billionaire I can buy an awesome Swedish submarine for less than the cost of a crazy megayacht. Unfortunately, skull shaped volcano islands are harder to come by.

This transformation in and of itself does not perform any compression. In fact it adds an additional string marker to the data. Performing compression on these strings is addressed here: https://www.cs.cmu.edu/~15451-f18

I have had high hopes for passive daytime radiative cooling since I read about it 10 years ago. Converting waste heat to an infrared wavelength that flies off into space day or night is apparently not that easy or cost effective right now.

Good advice of course. It is not valuable, and it is not my product - I merely worked on it. The real value was guiding me _away_ from a career as a programmer (and the friends we made along the way).

Much of my early post-college work is stored across a stack of Mac formatted Bernoulli disks. The software requires an ADB dongle to run, so physical hardware is required. I wonder if any of those ADB to USB adapters could be mapped into th
