Mp3 Player Headlight for bikes (new photos)

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

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. :)

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.

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.

SteamPunk Clock

steampunk clock

screenshot from solidworks

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.

Juicy Salif Model

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.”

Bike Light

Here is a new bike light with stealth concept.

Front side view.

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
