My dad has acquired an outdoor anemometer that’s cleverly built around a bicycle computer. The bicycle computer uses a couple of coin batteries (total voltage, 3V), and he wants to convert it to plug-in so he doesn’t have to keep buying batteries for it. I’ll be visiting in a couple of weeks, and he asked me to dig through my junk heap to find a 3Vdc power supply to bring with me.
Crap: the closest I could find was a 5Vdc power supply.
Question: is it likely that I will be able to power this bicycle computer from a 5Vdc power supply without frying it?
