Here is an other bicycle product.
There are already some products in the market that combines mp3 playing and a headlight but although china originated they are a bit too expensive. on the other hand, there are many headlights, hand torches and mp3 players which all are very cheap.
So I’ve concentrated on this deep 🙂 issue and designed an mp3-headlight-torch suitable both for bike as well as manual usage by using the parts of products which are already present abundantly and cheaply at the market.
Here is the design
First I’ve bought several cheap mp3 players. They are around 12$ in İstanbul and their performance is quite good, they even have radios and equilizers. 🙂
Here are the mp3 players
This product is aimed to be used on bikes, but can be used elsewhere where a small solar panel attachment is needed. The part is quite strong & sturdy , able to carry up to 1kg with ease.

I’ve made a toy VW T1 bus. Here are some images and the STL files for 3d printing.
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.

The creation of this article is a kitsch product that looks and pretends to be like a steam engine.
But within the body, there is microprocessor power and a graphics LCD screen that can display various clock faces.
It can generate a number of sound effects suitable for the current clock graphic displayed on the LCD.
The body is suitable to be produced at a 3D printer.
Our design is selected as the thing of the week in 3D Genious.

Bike Computer Circuit Schematic
This is a bicycle computer product with 16×2 LCD screen, real time clock, temperature sensor, light sensor, total & trip distance measurement, even a knight rider led display that changes its swing speed according to the bike’s speed. A very fun project.

The product design
This device is a temperature probe which measures temperature at a point and displays it on its 5×7 dot matrix led display.
