Tidy.  It something I've considered, but don't have any keen static cyclists to use it, so there was limited point.
I thought you should connect it to a kettle: once it's boiled you know you really deserve that cuppa. Wink

Did I read right, you're generating about 100W with 250W on a sprint.

Until somebody sets up an alternative, MCS is the only option.

Really nice! Very impressed with it. One day, when I get chance, I'll have a go. Funny enough, I reluctantly threw an old circular saw into the metal recycling. At the time, I was racking my brains to think what a nice flat piece of circular steel with a centre hole could be used for...

Same for me.  I wish I could make one. And knowing that I'd produce some juice that might even motivate me to go on the bike!

well what motivated me is to kill 2 birds with one stone Smiley
that's  :
fight the flab  bike and lower the dreaded electric bill  fume


anyways  i have done some changes to it
i got a grid tie inverter 14v - 28v 300w to try on it  on hooking it up and got peddling the inverter cut out !!!!
i was over powering the inverter  fume
i was kicking out more than 28v
so i got a bigger one 28v - 48v 600w and now its working fine  extrahappy
