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. Where he shows an MSP430 + the ANT+ AP2 module to use as an intermediary and convert old SRM powermeters to ANT+.
This is like my ANT+ to BT2.0 for another purpose… a much more complicated issue too. If you have an old SRM this should be very useful to you!

This is impressive! He’s gotten power consumption down to 160 microamps from a coin cell. He’s a much more experienced man than I in regards to this stuff.
There was also a discussion on Facebook’s “Training with power” surrounding ANT+ head units. Mark’s post in the ANT+ forum was removed or I can’t find it, however the opensource.quarq.us site still exists with his python scripts for ANTware II. It’s located here.
A big shout out and thanks are deserved for Mark I think. Cheers and thanks for promoting ANT+.
