Endtas is a website in which the visitors can find all necessary information to build a product specially designed to be home-built. There will be 3d files, circuit schematics, circuit board designs, interface designs as well as firmware for the embedded micro power.
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.
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.

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.
Not all squeezers are actually meant to squeeze. Perhaps the most famous example of this is the Juicy Salif, designed by Philippe Starck in 1990. It is considered an icon of industrial design that has been displayed in New York’s Museum of Modern Art. It is manufactured by Italian kitchenware company Alessi. Its diameter is 14 cm, height 29 cm, and it is made from cast and polished aluminium. As the founder of the company Alberto Alessi recalls “I received a napkin from Starck, on it among some incomprehensible marks (tomato sauce, in all likelihood) there were some sketches. Sketches of squid. They started on the left, and as they worked their way over to the right, they took on the unmistakable shape of what was to become the juicy salif. While eating a dish of squid and squeezing a lemon over it, Starck drew on the napkin his famous lemon squeezer.”
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 prototype made on multiholed prototyping board
The light is fixed to the handlebar of a bike by an elastic o-ring or a piece of o band cut from an old bicycle inner tube. There is a 3.5mm jack at the side of the product for charging the battery and an on-off switch at the back.
front view, all three leds are visible
The circuit uses 3 leds, one for standby and others 1w white leds for lighting. This is an intelligent lighting system with the details you can read from our first bike light article
