The transilluminator can also be modified to sit beneath the mini-gel electrophoresis tank (from a previous instructable), as described in Step 8. Used in this way, you can also visually track progress of your DNA during electrophoresis.
Open source hardware kit - This is an open source hardware project. To enable users to make or modify the device, I have included all of the PCB design files, enclosure design files and list of all hardware and electronics in a zip file attached below. We have also put together an LED Transilluminator Kit containing all of the parts described in this Instrucatble.
Step 1: Kit contents
- Printed circuit board and electronics: DC jack, resistor, switch and 72 x blue LEDs
- Laser cut parts: 6 x black acrylic parts, 1 x clear acrylic parts, 1 x LED diffuser, 1 x blue light filter and an amber lid
- Enclosure hardware: 4 x male-female standoffs, 4 x 3/4" long standoffs, 4 x 1" long standoffs, 8 x screws and a mini-screwdriver
- Power supply. 12V power supply with an output current of at least 0.25A. Optional addition to the transilluminator kit. We use one from Jameco Cat # 252824.
