My new light for the reader
I suppose you know the invention of
Lightwedge to read books and that Sony has adapted to its case to light.
This is a layer of methacrylate (I suppose) internally illuminated with LEDs that when putting on the pages of the book illuminate it in its entirety and without lights waste.
I think this is a great invention and I decided to ride one to see that such a sale.
The materials:
A plate-methacrylate which was home.
-5 White LEDs 5mm diameter and 3.5 v resistance and 20mA and five of 56 Ohms
- A holder of 3 AA batteries
- A bit of wire and some connectors and sockets
- A CD sleeve and a box of old nails
What he methacry first cut with a long equal to the screen reader and a width of 2 cm more. This is 12.5 x 11 cm
And a few notches cut of 5 mm to fit the leds. The extremes of 1.25 cm from the side or the other separated 2.5 cm
Then mount the LEDs. I used to base a piece of rigid plastic removed from a cable tray. I made a holes with a nail for each LED meter leg where negative and thus connect the LEDs in parallel, connecting the legs above positive and negative with resistance from below. The LEDs are bent to one side.
First light of evidence connecting the LEDs to the three batteries of 1.5 v put on the stand. Total 4.5 v
This promises! Keep in mind that the methyl carries on each side a plastic protector.
He protected the circuit with insulating tape to prevent short circuits or disconnections. I intend to make the invention beyond repair (all stuck) as the duration of the LEDs is very high and simplifies the assembly.
Then with the dremmel I cut the sides of the CD case along with a width of three cm. It should be the side of the bottom of the box that has angle and serve to make the box that will cover the LEDs.
With the methyl silicone thermal paste to the base of leds and cover these with the two sides of the CD which also hit with silicone.
I connected the cable positive and negative circuit of LEDs (secure with tape) to a male connector snaps and I've stuck to the top of the box. Cutting the rest of the CD sleeve of the two pieces of plastic triangular shape, I have stuck to extremes to stop all closed.
The following is painted in black compartment to prevent the LEDs light output.
While the paint dries, I have the power source by placing the battery holder inside a plastic box where you get the cable with comector female in the extreme. Pintaráde is also black.
So much for today. Tomorrow with the paint dries, withdraw the protections of methacrylate and try the invention. If it works later on I will make another more streamlined and better finishes.
Soon photos of the result.
