Valentine's day gift for 4 nights and 1 day
A couple of weeks ago, I decided to give my beloved on Valentine's Day a gift made by myself. I didn’t like homemade products found on the internet, I wanted to make something beautiful, but my own, unique. He stopped at a transparent sculpture with LED backlight in the shape of a heart, with the potential to use as a frame for a photo.
To attract attention, I will demonstrate the result:
And now, for those who are interested in how to make a similar gift for 4 nights and one day, I offer step-by-step instructions.
The first thing you need is a transparent epoxy resin, for casting medium volumes (~ 300ml at a time), MagicFast resin was recommended to me. I used about a kilogram, I advise you to take with a margin.
Also need a form. For the stand was chosen capacity 0.5l, and for the sculpture itself a silicone baking dish.
')
More LEDs are required. Were selected RGB diodes with a common anode for the heart, and blue for the stand. I also advise using the MGTF wire, it will not be so noticeable.
The list of materials for sculpture (control scheme is absent):
The result of the preparation: 494 UAH ~ $ 55.
During the day I work, I made the gift late at night - at night, as a result, my production phases are so divided. Independent actions can be combined, but do not forget that for mechanical operations, such as bending the legs of LEDs in sculpture, the last layer of resin should harden well. And re-fill the transparent layer after installing the LEDs can be performed immediately.
Wash and dry the forms well.
Stir the epoxy resin, pour into a new container, and mix well again.
Fill the first layer, it should cover all the irregularities of the form and prepare the basis for the LEDs, I needed 150-200ml.
In order not to waste time in vain, we bend the legs of the LEDs and part them at the same distance; for this purpose interboard connectors are used with a 2.54 mm pitch.
To fix the LEDs in the resin that began to harden, temporarily connect four diodes at the same distance, for rigidity I recommend using soldering.
After the resin thickens sufficiently, the LEDs can be arranged; in my case, I had to wait four hours.
Re-fill the mold with a transparent resin so that it completely covers the LED housings.
The housing for electronics needs to be modified to be able to open after pouring, for example, I made a rim using scotch tape.
Tint hardener, then perform the usual operation of mixing the resin.
Fill it in the tank for the stand and immerse the electronics housing with the lid up.
We remove the temporary fixation of the LEDs, bend the legs, solder, select resistors of 3 for each diode, and then connect the resistors for each color to each other. We also do taps from the anodes, as a result, we have 11 wires.
Then you can perform the last fill of the heart, I used a red dye.
Stand can get out of shape, free from excess tape and polish the bottom. In it we make holes for wires from buttons and LEDs, and also form LEDs to illuminate the stand.
We solder the buttons and prepare a mount for them.
Extend the shape, to fill the docking layer, I used adhesive tape glued together with a slight offset.
We take out the heart from the form.
We skip the wires into the holes, and pour transparent glue so that the resin does not leak, I do not recommend using hot melt glue, since the resin is heated during polymerization.
Prepare a support for the heart, I used a juice bag, twisting two 20 mm self-tapping screws.
We fill the tinted resin.
I had a bad luck with the control circuit. It was found a few errors, as a result of it had to be abandoned.
As a result, it was decided by pressing the button to turn on one of the colors for 1 minute, and turn on the backlight of the stand by pressing any button.
Also, the power had to be made from 3 AAA batteries, instead of the planned 2x.

The girl really liked the gift, and she agreed to temporarily return the statuette to carry out improvements by the eighth of March. There are plans to implement a control circuit, in particular, to add diode brightness control and a power supply voltage regulator.
