Re: E-Bike Expo, Portland May 20-22

I went Sunday and it was fun to ride so many bikes in the two hours I was there. My favorite rides were on: "Big Bud": http://www.electricbikeattack.com/easy-motion-evo-fat-tire-awd-electric-big-bud-2016/ the E-stream EVO-FS-3-29: http://int.bulls.de/en/bikes/show/e-stream-evo-fs-3-29/ and the Panth...

LED Bike Tail Light with Laser Safety Lane Review

This Groupon special caught my eye and I ordered 2.

Kenda 163026 Big City Slick Tire

These are a great tire for street use; put them on my Giant Yukon hard tail and the bike is joy to ride now. Silent and very low rolling resistance. Will order another set for one of my ebikes. http://www.amazon.com/Kenda-163026-Slick-Bicycle-Blackwall/dp/B00V3HW3JA/ref=dp_ob_title_sports One review...

Re: $25K military grade ebike...

I love how the terms "military spec" and "military grade" get thrown around when they don't actually mean anything. They do mean something; I regularly use mil spec electrical connectors and they are far superior than consumer grade connectors: https://en.wikipedia.org/wiki/U.S._Military_connector_...

Many thanks it works great at 12s lipo can't wait to try it at higher voltages! :P Any advice for not having the same problem with the Bafang controller that you experienced?

Re: Putting a Car Horn on my bike?

You could build a simple circuit using a capacitor that the Lyen dc to dc converter would gradually charge up. May have to play around with getting the right size capacitor; the bigger the capacitor, the more beeps per charge. I would charge the capacitor through a resistor, so that you don't hog al...

Latest, non-e-bike project...

This project was a hurried one in January to make a mushing stove. The rules for the Iditarod require a cook kit that can melt snow / heat water with a capacity of at least 3 gallons. The cupcake burner is original. The blue insulating pad is to prevent the stove from melting into the snow. Musher w...

Re: CO2 400ppm

The historical reason for the Hawaiian data is that it is where the long-term CO2 monitoring started. See: http://en.wikipedia.org/wiki/Keeling_Curve The data is replicated all over the world - even very far from volcanoes - CO2 mixes well in the atmosphere.

All very good engineering schools; since you are in Portland, you are welcome to come by and see some labs at PSU. I work in Civil and Environmental Engineering and when I was in your position of choosing a college to attend, I never seriously considered Civil. I did Physics and an exchange semester...

Re: Mystery Project

Still working on a proper scale to show the fluid level height. There is a mechanism in the reservoir - a block of plexiglass connected to a threaded rod with a handle and two guide rods on either side. Once we have the scale on top, it will be referenced to a zero line on the reservoir; any change ...
