Color Injection Lamp - Jumbo Size

I love this concept very much because kids like it very much. Now a days kids are always in mobile for study then for play and then for entertainment. Already i develop few projects with lights with arduino and Android. When i see through net i found this project is very interesting. I thank Mr.Taras Sgibnev, i see his model in web. It also teach kids the result of color mixing and make them happy. When you see you think its very simple to build, but it is little difficult to make it. I plan to make as a night lamp for our room. So with out using cardboard i use durable materials and also power supply directly given from EB supply.

After completion Its very big in size 2.5 feet height and nearly 1 feet X 1 feet square. Its a jumbo light.

Step 1: Materials Required

Materials Required

1) Arduino Nano - 1No.

2) Sliding variable Resistor - 3Nos.

3) Addressable RGB LED - 1 Strip (60 nos led).

4) 230V AC to 12V DC SMPS.

5) LM2596 DC to DC adjustable step down module.

6) 200ml Syringe - 6 Nos.

7) Plain PCB, Male and female header pins, Ribbon Wires etc.

8) 75mm PVC pipes - 690mm length .

9) 3mm Sun Shade sheet.

10) 8mm wooden board - 2 feet X 2 feet.

11) 4mm fish tank air hose - 3meters

12) Feviquick.

13) Wooden Sticks.

14) Wooden boards.

15) Food Colors (Red, Blue and Green)

Step 2: Circuit Plan

The Circuit plan is very simple and basic. 3 sliding variable resistor output connected with the analog pins A0, A1 and A2. Addressable led string data pin connected to D3 of arduino. Arduino Vin and gnd connected directly from 12V Smps output. Adddressable LED strip vcc and Ground to LM2596 output and LM2596 input connected to 12V smps supply.

Step 3: Make Shield

Every time i make a shield for each project and so i have a box full of shields. As per circuit plan i make a shield using plan board. I plan to connect the wires using male and female header pins, because while assemble the lamp we want to remove the wires and pass through holes. As per circuit pins with supply must be female connector, So Power supply input pin in arduino side must be male header and all other pins are out put from arduino so all other pins must be female connector.

Step 4: Cables Preparation

From arduino to Sliding resistor, i use long 9 color ribbon wire. Divide wires in to 3 sets and solder male header one side and female header on the other end.

Step 5: Power Supply Arrangement

I plan it to hang on the roof of the room. In the roof supply available is 230V dc from switch, So i use 230v to 12V dc converter. Don't connect the led strip power to arduino 5V because it may damage the arduino. So i use LM2596 to convert 12 V to 5V DC. Make a single female connector for the power out. And this is connected to the arduino male connector near the Vin side. Becareful while connect the header pin to arduino if reversed 12V send to LED strip cause LED strip failure..

Step 6: Careful With Power

Be Careful while working with the high power supply. I lost my multimeter while working, the markings are dim in the yellow multimeter. I put the mode in resistor and check the 230 V AC supply, its burned. I use thgis multimeter for last 20 years. I miss this multimeter but God grace it never cause more problem. So be careful.

Step 7: Light Arrangement

Actualy it is a 60 addressable RGB led. I use it for my previous project 7 Feet 7 Segment RGB Display With BT App. Due to space concern i remove the materials from that project and store it sperately. Now use that leds in this project.

Step 8: Arduino Program

This is a small Program. Use led PololuLedStrip library to drive the addressable led strip. Receive the analog signal from resistor in pis A0, A1 and A2 Use Map in arduino to convert the 0 to 1024 to 0 to 255 and check in each cycle if its differ from previous color then change the color of all leds's in the strip.

Step 9: First Trial

First check the circuit with the code and adjust the potentiometer to generate all colors. See the video of its testing.

Step 10: Syringe Fix With Sliding Potentiometer

This one is one of the difficult task if you have 3D printer then its very simple but i use woods and materials available in my box.

1) Remove the knob of the sliding potentiometer.

2) Cut the plunger round piece in the back.

3) Cut the plunger in the center up to 2 cm.

4) Slider base is higher from the floor so cut novopan sheets and stick with the base of the syringe using feviquick (qucik fixing gum). Don't use hot glue gun in the syringe side, because it cause syringe melt.

5) Screw sliding resistor in a straight stick with around 25cm between each sliding resistor.

6) Insert the 2Cm cut portion of the syringe plunger to the sliding resistor knob and hot glue it.

7) Arrange the syring straight with the sliding resistor and use hot glue gun stick it with the base stick.

Step 11: Testing the Syringe

Test all the three syringe fixed with the varaible resistor with another syringe as shown in the figure.

Step 12: Arrange Leds in a Round Pipe

1) I choose a 75mm pipe for led Arrangement. I found the LED strinp length is very high so first cut the pipe for 670mm height. At first the strip length is around 820mm (its made for my previoud project) change the strip length to 670 mm by cut the space between each led's and strick with tape.

2) Arrange the Leds around the pipe and Tie any three places using white twine rope. I have 7 strips used in 7 segment display but i able to arrange only 6 strips so remove the 7th strip.

3) Then move the strip and arrange in equal spacing.

4) using hot flue gun stick the strip with the pipe.

5) Then use the twine rope tie the wires with the pipe to avoid wires pop out. Now the Strip is ready and want to test.

Step 13: Test the Arrangement

Connect the Arduino, Potentiometer Syringe and power supply to the strip. And check all the leds are glow. On my checking after 2 and strip in third strip only one led glow after that all the leds are not glow, check and found the Led output dc voltage to next led is broken, resolder and found in the 5 the strip after 4 the LED all leds only burn in white color. Check and found in the 4 th led output Data pin broken, resolder it and found all ok. Change the syringe length and test the colors.

Step 14: Some Selfie

After hard work up to 2 am its some satisfaction on the result how it glow so remember that movement a selfie.

Step 15: Make Shade

1) For 3d printing this size almost 690 mm height shade is very very costly. so i search for low cost but same result shade. I check with thermocol sheet, Cloth and finally 3mm sun shade its result is amazing. 3mm white pvc sun shade sheet 6feet X 4feet is only 150Rupees (2 Dollars).

2) The height we want to take is 690mm + 8mm + 8mm (i have 8mm wood sheet for hold the shade so for both side 8 + 8). I take 706mm height.

3) First cut height the and check with the light how much distance give nice result. When very close light dots are shown so check with each distance and found almost 65 to 75 cm from the light it shows the nice glow. So the square we want to cut is 80 cm for the light + 70 + 70 (for both sides) = 220mm.

4) So impress the sheet with thick screw driver in each 220mm (carefully impress straight line)

5) Take four part and cut the lost.

6) Paste the edge with feviquick (quick fixing solution).

7) Now the lamp shade is ready.

Step 16: Check Shade

Test the lamp shade for results. The result is superb. More than i expected.

Step 17: Make Lamp - Wood Works

1) Check with the had ware store and found 8mm wooden sheet dark brown on one side and white on other side. I need 2 feet X 2 feet. But the size available is more than that.

2) I want to cut 6 square pieces of size

a) 49 X 49mm for holding the light pipe in the center with out moving

b) 220 X 220mm for holding the shade with out moving.

c) 250 X 250mm for the base and top of the lamp.

3) In all the eight pieces we need 17mm X 27mm rectangular hole in the center to connect the syringe holding stick.

4) First i try to cut the pieces using hands but after cut one piece 220 X 220mm its very late night and i am tired. So I left the other cutting to the wood workers.

Step 18: Lamp Bottom

1) Stick 220mm and 250mm pieces together as shown in the picture using qucik fixing paste (feviquick). Don't stick the 49mm small pieces because it want to move.

2) For syringe hose we want to put three 4mm holes. The hole must be between the stick hole and the LED pipe. So put a piece of pipe and mark 3 points inside the pipe and put three 4mm holes.

3) The total height of the wooden pieces are 24mm(8mm board 3 layers). So put two 4mm hole in the bottom of the Syringe holding stick at (PCD) center distance of 29mm (1mm clearance). Insert a piece of rod and stick the top rod and bottom rod want to be removable.

4) Connect the Sliding resistor wire and using wire tag correct the wiring.

Step 19: Top Plate With Circuit Box

1) For top plate we want to put 2 holes one inside the pipe to bring the Potentiometer wire to the microcontroller and another outside the pipe to bring addressable led wire to the microcontroller.

2) For place power convertor and microcontroller take a wooden switch box of size less than 250mm X 250mm. Check the circuit and smps sit inside the box.

3) Put same size hole and the pole slot in the wooden box and the top cover of the box. Put a hole in the side to bring the power supply out from the box.

4) Stick the box in the top of the 250mm size board and stick with using feviquick.

5) Arrange the Circuit and the smps and LM2596 inside the box and leave the center place to insert the stick.

6) Paste all inside the box using hot glue gun.

7) Check the all the circuit and lights by connect the powersupply, Led and potentiometer.

Step 20: Start Assemble Lamp

1) Now all the arrangement are ready so no more drilling or cutting works.

2) Start from the bottom. First insert the bottom plates and insert the iron rod in the bottom hole. Now when you hold the top of the stick the bottom plate hang.

Step 21: Filling Colors in Syringe

1) Cut 3 pieces of 4mm fish tank air tube and insert through the bottom plate hole.

2) Prepare the color water Red, Green and Blue using food grade color.

3) Fill the tube first and connect the hose with the syringe fitted in the rod.

4) Take 20ml of same color solution in a new syringe and fitted in the opposite side of the tube.

5) Like wise fill the other 2 color. I mark from bottom first syringe is Red, second green and last blue.

Step 22: Check All Syringe

Check all the syringe working properly and sliding resistor movement.

Step 23: Complete the Lamp

1) Insert the Syringe holding stick to the LED pipe and take the wire from the sliding variable resistor to the top.

2) Insert the 49mm square wooden piece from the top and insert it inside the pipe and it went up to the top slider varriable resistor. So it never allow the led pipe to move in any direction.

3) Now take the shade we already made and inset it over the LED pipe and insert the bottom 220mm sheet in to the shade, So the shade hold in the bottom.

4) Take the top plate with the circuit and insert the wires from the sliding resistor and LED through the hole and insert the top plate.

5) The top 220mm sheet insert into the holder and now the hade dont able to move in any side and all are hold tight.

6) Connect the sliding resistor and LED wire headers to the shield.

7) Use wire tag neat the wiring.

8) Close the top Switch box.

Step 24: Checking and Hanging

1) Before hanging check the working of the lamp. Its very nice and color full.

2) Connect a chain or a rope in the top hole of the stick (i already put a 8mm hole in the top of the stick while put hole for the bottom holder).

3) I hang it in the center of my room and connect a very long wire to connect with the switch board. If also have concealed wiring in the top to connect the wire directly to supply. But now i have plan to hang in another room for some days for my kid play. So i use plug for power supply.

Step 25: Color Injector Lamp

Its all done and the result also fantastic. To find the result u want to make one. Because while take video using camera due to latest camera features while change some bright colors it auto focus and show different color. Even with sun shine and also indoor light the color is very cool and superb.

Step 26: Full Fun

I finish the project at early morning 5am work through out the night and even after i spend more than a hour with the lamp to change color and take photos with it.

Step 27: Kids Love It

In the morning when I show it to my kid she is very excited and play with it. She is very happy to see the color change while inject the color and remove the it. She see the result of color combination physically. But ask lot of questions one example question when add all three colors the output in the light is white but when add all three colors in water color it result is black why?.

For this project i daily update the works and completed on 26feb2021 morning 5am. Its a nice project with wonderful result. Taking spare from various projects. If purchase new the time may less but more cost. For this project i spend, addition charge of 2000 rs (around 27 US dollars).

While doing this project i lost in multimeter so it added my cost. Be careful while working with high voltage power supply.

Again very very thanks to Mr.Taras Sgibnev.

Thank you for going through my project.

Lot more to enjoy...............Don't forgot to comment and encourage me friends.
