Mini mp3 player holder for bikes

This is a new mounting accesory for mini cube mp3 players which are abundant on the market. These nice and very cheap mp3 players can be fixed on any bike handle or 1in dia pipe with this design. Tested and approved, works quite good. A little piece of rubber, tire patch or silicone glue placed and dried before assembly will make the device hold its groud firmly while supporting your mp3 player.

Bike computer with graphics LCD screen

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.

Mp3 player holder for bikes

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.
