Hello fellow DIYers
I came up with the original concept and design of "Kevin Bragg" of a lithophane lamp which I really like.
However his design wasn't ideal for my concept so I decided to redesign all his work, not exactly a remix as I did everything all over again. But I used his lamp as my main concept, hence giving him his proper attributes, Thanks, Kevin!
This a real DIY
• Power Cord (12DCV)
• In line switch or other on/off switch
• 8 LED's (any color you want)
• Resistors (270 ohms) If you don't have that you can use max 300 ohms or solder in parallel or series depending on the ones you have (ohms law)
• Haven't had problems yet. LED's work great and don't heat up that fast. I added a thin layer of hot glue on top of each led to make the light wider.
I Run the lamp on for 2 days straight with no issues.
Make sure to print 8 lithophanes from this website!
The settings I used for these are on the Images
Prepare the Lamp model by printing all files ( you will need to print twice the "Middle part" as flipping it connects
Solder LEDs in a pair to a resistor and put them one side negative and other positive (up and down) do this for all sides like in the images, add shrinking tubes to the connections to make it safe since they're going to be tight and pull positive wires from one side and all negative wires to the other side. Solder each terminal (positive to positive and negative to negative to the power cable)
For the power supply, I used an old charger with these values
Input: 100V -240VAC 50/60Hz.0.3A
OUTPUT: 12 V DC 500 mA
Print all lithophanes and make sure they fit on the tabs (print one and test you might need to scale them depending on each printer settings)
To seal the gap between images you can use silicone glue (hot silicone gun) and start by dropping a line of it making sure you add more than enough to cover the whole area. Make sure the silicone goes over the lithophanes and use a precision knife to cut or trim the silicone in a straight line. Creating a seal between pictures
Connect them to the outlet and enjoy!
you might want to cover the LED on a reflective plastic or tape to make the light brighter with a bigger radius to fit each lithophane respectively
I used a charger like this, strppied the connection and separeted the positive and negative terminals
2 Resistors in Series for 150 ohms
Adding a 120 ohm resistor in series to add a total of 270 omhs
