How to Make a Flashlight

Tip 1: How to make a flashlight

Paper lanterns have always been simple and bright Christmas decorations in all nations. Make your own lantern is quite simple. Consider a simple but interesting models.

July Toy “flashlight” to be graceful and light. For their manufacture take color paper, PVA glue and scissor. Cut a rectangle of colored paper width of 150 mm and a length of 200 mm and gluing the side length of 150 mm.Den resulting cylinder put on colored paper bottom circular circumference of the cylinder and cut the two is the same. The two free edges of our design, we will cut the strips to a depth of 5 mm. Bend results bangs inside, smear it with glue and glue the cut circles. From elegant strings do loop and glue to the underside of work piece. For this thread we will hang on the Christmas tree lantern. The remains to decorate, pasted shiny glitter, stars, or other details,garlands to produce more complex flashlight. Prepare two sheets of double-sided colored paper. One rectangle of 150 mm by 200 mm and a square of 200 mm.Vi glue the response rectangle with cylindrical shape, height 150 mm. On square piece top and bottom draw a line at a distance of one centimeter from edge. Lay to the square in half we cut the sheet into strips, from the fold before line. Expanding list, not secure cut square of the upper and lower edge of the cylindrical work piece. Fixed eyelet to the flashlight could hang and decorate it with threads, beads and confetti.The square the flashlight can not cut bangs, and looted an openwork pattern.

You can also make a Christmas tree with a flashlight lighting. Take few sheets of double-sided colored paper. From leaf cut out rectangular billet of 150 mm by 200 mm, top and bottom draw a line at a distance of 20 mm from edge.Bay rectangle in half of a fold will cut into strips of width 20 mm and a selected line, cutting them from one side to 10 mm.Vi unfold glossy paper, and bend the cut portion of the same direction. Draw free sheet amusing figure, height 110 mm, and cut ten. Carefully stick the shapes of the curved portion of preform. Glue ends of preform width. If you want to attach an edge of a flashlight shining a bright ribbon or string to hang it on tree. When we hang a flashlight, we drop into the center of the lamp garlands, then the light turns on.

Tip 2: How to make a laser from a flashlight

In recent years lasers are very popular. Produce laser home is quite real. The is only necessary to have some skill with a soldering iron and features “+” from “-” installation system.

Production of laser – some fun

Guide

1. If you want a powerful laser with emission of 200 mW, find a suitable DVD of the work cart and mounted on the head laser. Determine what you want to have a glowing, red or blue-purple.

Flashlight

pick suitable illumination wavelengths ranging from 380 nm to 800 nm, show characteristics of different emitters.Can obtained weak emission remove the same block, but because of a CD-unit. Both units should write. Badly light and get out of a printer, bar code scanner, mouse.

2. The design of the device can be very various. Carefully reviewed it without too much trouble to screw some screws.The laser unit is mounted on the carriage, which you can easily eject after removal brackets. Take then remove the optical element unit DVD, formerly “sitting” all conclusions on foil or thin wire wound correctly, eliminating degradation of statics. Decide on each of the three results:

– 1 output “+”;

– 2 feed “-“;

– 3 output is not used.

3. Power Laser Diode 3 volt.Use two “finger” batteries. You can take to power a Conventional crown and then collect an additional voltage regulator krets.Detta options Provide a more long-term use of your laser. Findthe ceramic capacitor 10 pF and a Polar 100 microfarads / 16.Select the directory of the stabilizer, the equivalent voltage of 3 V, for example, KR1158EN3V.

4. Addition Choose a Suitable Enclosure and Micro Switch.

To start the whole process of assembly soldering of ceramic containers to the terminals of the laser diode, remove the protective foil and solder polar capacitor with the right polarity. ROLL-ka has three conclusions:

– a stable food + 3c;

– 2 general;

– 3 input voltage.

Again, strictly considering the polarity of the stabilizer and the laser diode, make this part of the wiring of circuit. Nu open circuit power supply circuit and collected solder micro. Verify the composite circuit and try to incorporate.

5. Carefully remove the resulting product and place it in the body prepared flashlight , after removal of the glass with a flashlight .Perform you own a laser and without dismantling the device and surf the Web, shop and pick up the necessary (or order) laser device.
