How to make your own LED projector lamp

Posted: 03 Nov 2011 05:06 AM PDT

Sunny Goel:

LED Projector Lamp
LED Projector LampMaking LED Projector Lamp.

In an LED projector lamp, an LED is used instead of the filament based bulb which is used in standard digital projector lamp, also known as UHP (Ultra High Performance) lamp. The LED lamps come with a long list of merits in comparison with the UHP lamps. The most remarkable quality of an LED lamp is that it is far more durable than a UHP lamp. An LED lamp has a consistent, stable and distinguished color output throughout its lifetime. On the other hand, the color output of a UHP lamp diminishes as the time passes.

UHP lamps demand very high maintenance expenses because the bulbs which are used in them are not very durable. They are very expensive to replace. On the contrary, LED lamps does not require frequent changing of LEDs. Due to their qualities like small size and their capacity to work at a lower temperature, LED lamps can be designed to be extremely small, light in weight and above all portable. That is why these lamps are also mentioned as micro or pico projectors. However, LED lamps do not offer good brightness in comparison with UHP lamps. The lumen production in UHP lamps ranges from 2000- 5000 lumen or more. LED lamps which produce only 50- 500 lumen.

Let us see how to make your own LED projector lamp at home or in your lab.

Difficulty Level:


One need to perform steps like soldering and gluing. Good knowledge of circuits is also required.

Time Required:

1- 2 hours approx.

All the essential parts and components need to be kept ready at hand.

Resources Required:

1. A Project Box

2. Powerful LED

3. A Slide Projector Lens

4. A Power Supply Unit (PSU)

5. Small Fan

6. Power connector

7. Magnified/ Fresnel Lens

8. Condenser lens

9. MP4 Player with a LCD screen of at least 2 inches

10. Some cables

11. Hot Glue Gun

12. Soldering Gun

13. Some Screws

14. Heat sink

Estimated Cost:

$120 approx.

To lower the cost, certain equipment can be rented, borrowed or bought second hand.


1. Take the MP4 player apart and then carefully disconnect or separate the LCD from the circuit.

2. Remove the LCD and backlight from the casing.

3. Cut a piece of something rigid where the LCD is going to be.

4. Fit the LED to the heat sink. Take a drill and make two holes on the heat sink to attach the LED firmly on it with screws.

5. Wire the cables and make connections.

6. The most important and crucial step is to place the LED, the condenser lens, the Fresnel/ Magnifying lens,the LCD and the slide projector lens in a line. Make sure that the center of these objects must be in a straight line. You have to shuffle these objects many times to get the right distance and desired results.

7. Once you are done with finding proper distance between all these objects you can decide the size of box required for this purpose.

8. Now put the fans near the LED so that the heat generated can be reduced.

9. Check the projector in a dark room just like in a theater to test whether the projector is properly or not. This way, you can find out problems with its functioning, if any.

Frequently Asked Questions:

1. I am not happy with the results of my LED projector. The LED which I am using generates 750 lumen. Should I go for a more powerful LED?

Ans: Yes, because the picture will become clearer and brighter with increase in the luminosity of the LED. So, if you want better results, you should go for an LED that generates more than 1000 lumen.

2. What things should I do to make the picture more clear?

Ans: Go for a more powerful LED. Secondly, the Fresnel lens, condenser lens and the slide projector lens should be of high quality. Lastly, make sure that all of them are placed in the right order and at right proper distance.

3. Where can I get the resources needed for making of an LED Projector Lamp?

Ans: You can get the LED and the box at any radio shack or electronics components store or hardware store. The rest you can order online like on eBay. You can buy new components or you can go for second hand products depending on your budget and requirements.

Quick tips:

1. If you want a good picture quality then always opt for a powerful LED, good quality of Fresnel lens, condenser lens,slide projector lens and LCD.

2. To avoid any confusion, get the material together and follow the steps one by one.

3. For better results you have to try many combinations of distances between the LED, the different lenses, the slide projector and the LCD. You can either get it right by trial and error or you may calculate the distances by drawing an optical diagram.

4. While fitting LCD make sure that the image shown is upside down so that the image projected by it will be straight.

Things to watch out for:

1. Make sure to align the centers of the LED and the lenses.

2. Pay proper attention while doing electric work like making connections of wires and placing the components in order.

4. To reduce the heat generated, use of heat sink and fans is absolutely essential.

5. Removal of LCD from its panel should be done carefully to avoid any kind of damage to it.

portable Guitar Amp
portable Guitar AmpMaking your own portable Guitar Amp.

The guitar is a wonderful musical instrument which is capable of providing both melody and rhythm. However, every guitar player would have experienced the problem of low volume. The guitar is rarely heard unless the surroundings are absolutely quiet! To solve this problem, the guitar amp is often employed. If you have some knowledge in reading circuit diagrams, this tutorial will guide you to make your very own portable guitar amp.

Difficulty level: Moderate. This project requires some expertise in reading and making circuits.

Time required: This project will require about 3-4 hours to complete. You can make many more customized improvements and that will take an hour or more.

Resources required:

1. 12.5 VDC wall transformer - DCTX-1285

2. Coax power jack, 2.1 mm - DCJ-21

3. Coax power plug, 2.1 mm - DCSID

4. 1/4″ Mono jack - PHJ-S

5. Perf board - PC-1

6. Black plastic case - 1951-MSBK

7. 9 Volt battery snaps - BST-3

8. SPDT toggle switch - MTS-542

9. 9v 250 mah NiMh battery - NMH-925

10. Miniature full range speaker - SK-408

11. 500 ohm trim pot - TPS-500

12. LM386 amp - LM386N

13. LM317 volt regulator - LM317T

14. BC327 transistor or an equivalent

15. Resistors of 10 ohm, 240 ohm, 470 ohm, 1.5K ohm, 10K ohm, 1.5M ohm

16. MPF102 transistor

17. Capacitors - 0.22 uf, 10uf 16V (x2), 100 uf 16V, 0.05 uf, 1000uf 25V

18. Case for the charger circuit

19. Hookup wire

20. Strong glue

21. Sanding drum

22. Small heat sinks

23. Ammeter

Estimated cost: The cost here depends entirely on what you will have to purchase, what you already have and what you manage to scavenge. Hence, it is totally variable.


1. Let us first make the enclosure box. Drill a 1/4″ hole on one side of the box for the input jack.

2. Drill two holes of the same size on the other side for the charging jack and the switch.

3. Drill another hole in the back to fit the clip too.

4. Drill more holes on the narrow end of the enclosure and a few more on the adjacent sides to act as the ports for the speaker.

5. Place the speaker face down on top of the enclosure and trace a circle of its size.

6. Drill out the center of this circle and then use a sanding drum to dremel this hole.

7. Fit the speaker and use glue to stick it in place.

8. Now built the circuit that is necessary. Instead of going into the details of explaining the circuit, we present the circuit diagram below. Follow it to the hilt.

The schematics
The schematicsFollow the schematics carefully and that will be a major task accomplished
  1. Place the circuit that you have built inside the enclosure. The battery is at one end and the two jacks are opposite to each other.
  2. Mount the switch and amplifier circuit below the speaker.
  3. Add two small heat sinks above the amplifier clips.
  4. Add the clip from an old tape measure behind the amp so that it can be clipped on to the strap of the guitar.
  5. Glue a 1/4″ diameter white tubing along the borders of the speaker cone.
  6. Cover the front of the amp with grill cloth. Stretch it completely so that there are no creases running across.
  7. Use hot glue to stick the cloth behind to the cover of the enclosure.
  8. It is now time to make the charger. The schematics for assembling the charger are giver below. Follow it carefully.
    Schematics for the charger
    Schematics for the chargerThis should be pretty easy to follow and make

9. Hook the positive end of the charger to one terminal of an ammeter. The other terminal is connected to the positive end of the battery. Connect the negative end of the battery with the negative end of the charger.

10. Increase the trimpot on the charger till the current displayed in about 30mA.

11. Mark the trimpot to this point and keep it fixed there.

12. Mount the charger too in an enclosure and add heat sinks to it.

13. Now your guitar amp is ready for use.

Frequently asked questions

1) You have mentioned the SK-408 speaker. Can I use any other speaker for the project?
Ans: The speaker that has been suggested here has a resistance of 8 ohms and can thus handle about 3 Watts of power. It is also shallow in its depth and makes it possible to insert heat sinks. These specifications are important for the project and it would be better to stick to the above mentioned speaker unless you can obtain another one with the same specifications. Different speakers will also give different performances. Experiment at your own risk.

2) What are heat sinks and where do I get them?

Ans: Heat sinks help to dissipate the heat that is formed in the circuit. Too much heating can harm the circuit. The heat sinks used in this project are nothing but cut pieces of a regular heat sink that have been filed to fit in. You can glue them using thermal glue that is available.

Quick tips

1. You can add many customized effects to the amp. For instance, you could stick custom decals to the back of the amp to give it a cool look.

2. Some of the resources necessary for the project could be scavenged to save money.

3. Turn on your amp only after plugging in a guitar. Else you will hear a painful screech.

4. Keep the volume on the guitar at a level that the sound from the amp speaker does not distort.

5. It takes about 12 hours to fully charge a completely dead battery.

Things to watch out for

1. Drill and dremel out a hole with the sanding drum for the speaker, ensuring that you do not overdo it. It should fit the speaker.

2. Be careful while using the hot glue and quick glue. These glues bond very strong and fast. Skin could easily get bonded by mistake and result in injuries.

3. 30mA is the maximum, safe charging current for a rechargeable NiMH battery. Do not exceed this value.

4. While you are charging the amp, do not play it at any cost.

How to make a dusting accessory for your vinyl turntable

Posted: 03 Nov 2011 04:48 AM PDT

Jancy James:

Vinyl turntable
Vinyl turntableAs anyone who still likes to enjoy their vinyl will know, dust is a bugger

The days of the vinyl turntable are passé, but there are still some who want to revive memories of listening to retro songs with their near and dear ones. Those who still have their vinyl would know how difficult dusting can be and how irritating the crackle of dust can be when we want to listen to our favorite numbers.

Though the antistatic brush arms do a pretty good job, they do have a tendency to get swing to the middle track and get stuck there. This will prevent the inner tracks form getting cleaned and so a proper cleaning process cannot be attained. With a bit of time and patience, we can make our own dusting accessory for our vinyl turntable. This accessory does a wonderful job of tracking the stylus position and preventing the dust from settling. Let us see how such a dusting accessory can be made at home:

Difficulty Level:


Time required:

Less than one hour

Resources required:

1. A piece of fleece material to make the brush

2. 9 cms of fine wire or a twist tie

3. An ink reservoir end from a Bic-style biro

4. Glue

5. One Sugru sachet


1. Take the Biro reservoir and using a paper cutter or a sharpened knife cut off two sections, one short and the other a little longer to form the core part of the brush. The shorter piece will be used for mounting the brush on to the vinyl turn turntable.

2. Keep the back of the fleece or velvet up and apply glue over it. Make sure that the glue is not in excess to make it leak to the outer surface. This will give a hard surface which can cause scratches on the vinyl surface.

3. The longer tube can now be rolled into the fleece and allowed to dry completely.

4. Once this is dry, you can insert the twist tie into the biro tube and bend the end of the twist tie to hold the fleece with the tube in place without falling out.

5. Now, place the brush on the tone arm of the vinyl turn table to check whether it fits well and remains neatly.

6. Take Sugru and mount the shorter piece that you have cut on to the headshell of the turntable. The ends of the tube must not be blocked with Sugru. Wait for the Sugru to get cured.

7. Now, you can fit the brush on the headshell. For this, the free end of the twist tie must be inserted through the hole of the tube that you fixed on the headshell.

8. The twist tie must now be bend inwards to form a right angle. The end where the fleece is fitted too must be bend in a similar manner to form a right angle so that the entire twist tie along with the brush forms a wide U shape.

9. The free end of the twist tie at the side where it is mounted on the headshell must be bent slightly over the top of the headshell. This will allow the brush to get lifted from the record automatically when the tone arm is raised.

10. You may now attach the headshell back to the tone arm and the stylus can now be inserted back as well.

Frequently Asked Questions:

1. What other materials can be used for making the dusting accessory other than those mentioned above?

A: Other than fleece, you can also use velvet or felt as well. Instead of Sugru, you may also use Blu Tack which is as effective.

2. How do I prevent damaging the headshell while mounting the dusting accessory?

A: You have to be very careful while fixing the dusting accessory as the ends of the twist tie can scratch the delicate parts if not careful. For this, you can remove the head shell from the tone arm and do the mounting so that the vinyl is not damaged in the process.

Quick Tips:

1. Always check whether the brush fits well on the tone arm before mounting. This will save a lot of extra work like removing and fixing it again.

2. While fixing the fleece on the tube, ensure that just the right amount of glue is used to prevent hard surfaces from forming on the dusting accessory.

3. When you attach the tone arm, care must be taken to re balance the arm as more weight has been added to it. You must also twist the brush adequately so that it comes in contact with the vinyl surface.

Things to watch out for:

1. Remember that the headshell must not be removed unless you know how to fix it back.

2. It is also not advisable to undertake such DIY tasks if you are not good with electronics. It can damage the entire turntable.
