It’s finally on order! The nRF51422 DK / EK kit that uses the new ANT+ transceiver with Arm Cortex M0 all in one chip. So that means that development is [ … ]

So a while ago I noticed some posts in the ANT+ forum by Mark Rages. Turns out he’s the “electronics guru” of Quarq. He has an old tumblr site here. [ … ]

This data was gathered using a Garmin Edge 500 and my prototype L/R measuring Power Meter which is still being worked on. The latest upgrade to my prototype power meter [ … ]

So V2 had some superior measurement features. If you recall here I discussed about how applying a torque through my foot caused the readings to skew. So installing a couple [ … ]

This little chip is going to revolutionize my design, simplify it, add thermal compensation (if needed, need to do temp testing) and drop the price of the board.Potentially the electronics [ … ]

As mentioned in my previous post on the information I found on the new Rotor Power Meter, it became official yesterday that the Bicycle Power Profile is upgraded to V3.0. [ … ]

I’ve been diligently asking and looking and scouring the web for what metrics the new Rotor Power Meter will contain and now I know. Quote from the www.thisisant.com site: Balanced [ … ]

Some longer testing (1.5 hours) today and I’ve come to a few conclusions. My calibration is off It doesn’t matter that my calibration is off, the crank shear gauge on [ … ]

Snow day today which means I didn’t make it into work. Seriously though, I tried. Shovelling out at 8am when the snow was at it’s worse and not a plow [ … ]

I got my breakout boards today for the 24 bit Sigma-Delta ADC’s. Soldered and conductivity tested. Now to wire them to an Arduino and a strain gauge. Approximately 3ma for [ … ]
