framed color changing led art
Velum in the paper section of your local art store also does a great job.
5x4 matboard frame with 2 \"x 3\" windows: you can buy a piece of black mat cut to these sizes for a few dollars in any frame store, or with the right material, for example, a hard black card paper is cut by itself.
Battery Case for 2 AA batteries with lead wire and power switch: these can be purchased online from Jameco 216120 section or found in Digikey. com or Mouser. com as well.
Similar Battery brackets can be found in Radio Shack, but you may have to weld a simple power switch in the circuit yourself. 3 RGB color-
Replace the LED: I got these here: looking for \"slow color change for 5mm RGB LED \".
\"Make sure you get it clear, because decentralized projects don\'t work either for this particular project (
But you can do other cool things with them! )
Everything in this store seems to have a free resistor, you don\'t need this item, but hey, free resistor.
2 docking :(tee hee. . . butt splices).
These can be found in the Radio shed;
18-things in scope
The instrument around the 20th works normally. I use the non-shrink-wrap-
Coating, but the coating should work properly.
You can also get these from Jameco part 494469, but the minimum order is 100.
The picture also shows: glue point.
These are attached to the kit and, as an alternative to hot glue, some parts can be connected together.
These can be found in the crafts store (
You should get the biggest, most tacky (stickiest)ones they have)
, But the hot glue gun also works well in these steps, and in any case, it\'s good when you need to \"customize\" your LED artwork.
You also need 2 AA batteries and some clear tape. TOOLS (not shown)Needle-
Nose pliersWire Clippers and strip: these may be needed to cut and trim the wires on the battery box.
If you want to cut your own screen or mat, scissors or similar cutting tools.
Hot glue gun: As mentioned above, some parts can be connected using glue point instead of hot glue, but the hot glue gun is optional (
But highly recommended)
Steps to customize artwork.
Flip your cushion frame (or equivalent)
So you\'re looking at the back \".
\"If you use a hard piece of plastic as your screen, position an edge so that it is close to a wide edge of the frame (
As shown in the figure);
This will be the \"bottom\" of the frame and the battery pack needs something solid to connect.
If you use velum, place it in a higher position in order to expose as much as possible the bottom edge of the frame (
When using velum, you need to connect the battery pack directly to the mat board).
Next, tape the left and right edges of the screen to the back of the frame.
Make sure the tape does not overlap with the window, or when the screen is lit from the back, it is displayed.
Observe one of the LEDs carefully and note that one of the lead wires is longer than the other.
A long lead is a positive one.
Gently bend the positive lead of about 15 degrees.
Do the same for another (negative)lead.
Bend the remaining 2 LEDs in the same way.
Keep your 3 LEDsby-
Side, make 3 positive leads parallel.
Place docking joints on all 3 front leads.
Squeeze the butt joint with pliers, surround the 3 LED leads in it, be careful not to curl the relative position of the joint.
Apply enough pressure to keep the 3 leads firm.
It is very important to remember which LED leads are positive;
You may want to mark this joint with a small piece of tape.
If you are confused, each LED lens has a small flat point next to the negative lead.
Now collect the negative leads and place another docking joint on all 3 leads.
Again, give it a good squeeze and be careful will only press the LED side of the joint.
Remove the end of the Red Line lead from the housing and insert it into the opening end of the docking joint connected to your positive LED lead.
Squeeze the joint firmly on the red line with pliers.
Next, insert the black line in another joint and squeeze it.
Now gently bend the lead at each joint and look like a picture.
It is very important that these two connectors never touch, and if they do, it will prevent your LED art from lighting up and quickly drain the battery.
Open the battery box.
Sometimes there are few fixing screws in these cases to fix them, in which case you need a small cross screwdriver to remove it.
Turn on a few AA batteries, turn off the chassis and turn it on.
The three LEDs should be turned on immediately and color change will begin.
If not, here are some trouble-shooting tips: If some, but not all, LEDs are turned on, you may turn on one or more LEDs backwards;
That said, you didn\'t arrange all the front LED leads.
You may need to pull the curl down with a pair of pliers or cut it off with a wire cutter.
There should be enough extra LED to re-
But you may need more docking joints that can be found at Radio Shack.
If none of the LEDs light up, you may have reversed all LEDs (i. e.
, Connect the red line where the black line should be, and vice versa).
Put the battery back into the bracket instead of pulling the joint open or cutting. Still no luck?
It may just be a bad connection.
Try to cut off the criminals and re-
Peel off the wire and re-
Blank holder with new butt joint.
This step explains how to connect the LEDs to the battery box using the glue point that comes with the kit.
Alternatively, you can use a small amount of hot glue and it will actually be a little stronger once set.
Gently peel the glue dots off, be careful not to touch the glue dots or let them stick to anything (
They are like sticky).
Cut off the backing so you have a point and stick it on the box near the switch.
Press hard and peel off the backing (
Use your finger to help glue points stick to the box if needed, but do not touch the glue more than necessary).
Now press hard on one of the curled joints (
Which is okay)
Stick to the glue point
It\'s time to get to know the look of your LED art and make any adjustments or changes.
Dim the light, place the switch on the housing in the open position, and keep the frame on the LED/housing assembly so that it projects to the back of the frame.
Take a look at the front of the work and see how the colors and patterns change over time.
You can adjust the look of your product by gently repositioning the LEDs.
Without any further changes, your LED artwork will loop through the seemingly endless pattern of light and color.
You can further modify the look of your product by dropping a small amount of hot glue on the LED lens.
You can create patterns that are more interesting and complex than seeing separate red, green and blue spots on the screen.
Plug in your glue gun and give it a few minutes to heat up.
If you are a child, you definitely need to be supervised by an adult!
Carefully drop a small amount of glue on the LEDs.
Let the glue cool and see what it looks like when it is projected on the screen.
Give it a few minutes to let the LEDs cycle through their various colors.
Feel free to try as it\'s easy to peel the cooled glue off the lens and try something different!
Once you are satisfied with the look of it, use the remaining glue to connect the frame to the battery box (
Hot glue can also be used).
Apply the dots to the front of the box.
Peel off the backing and attach to the lower edge of the frame, the plastic screen extends all the way to the edge of the mat.
Apply some pressure to make it stick together.
You have one now. of-a-
Real object of LED artwork. . . enjoy!
I really like to use these LEDs and they have a lot of creative possibilities.
