I’ve designed a complete new hardware & software for the bicycle comp that I’ve published some months ago. This one has a 128X64 monochrome graphics screen instead of the 16×2 character display of the former one.
this has got real time clock as well as the temperature sensor like the old one. But all data can either be shown fully digital or two different analog display modes.
I’d published a product for mounting mp3 players to bikes some months ago. Recently I’ve resized it, converted its locking mechanism to a double lock for added strength and printed one, by using an UP printer. I’ve assembled it to my folding bike with the mp3 player that i’ve bought from the market for just 14$. The design turned out to be nice, performed its duty well, holding the mp3 player in place at the same time directing its sounds towards the rider. Though the speakers of the player were at the sides, the sound was being distributed to the sides and music was a bit difficult to hear without redirection.
now sound is good. The STL files are at the end of the article for the ones who want to print their own product.
