This week of Fabrication’s enclosure, I chose to use acrylic with standoffs as the enclosure of my LED light panel for photo shooting. I learnt from the experience of making it with trials and errors, and figuring out the sizes of nuts and screws for the standoffs was hard. If I could buy more time and notice the errors earlier, I could make a better enclosure.
- Acrylic 12×12
- Standoffs + nuts + screws
- Laser cut
- jump wires
- battery holder + battery
- LED light strips
- glue gun
Step 1: Using laser cut for acrylic enclosure
I used adobe illustrator to laser cut 3 panels for enclosure in the first plan, and using standoffs to build up the panel. Unfortunately, I realized I measured the holes wrong by using the diameter of the standoffs. To fix this problem, I used glue gun to narrow down the size of the hole, to let the screws and nuts to fit in and won’t fall off.
Step 2 : Applying the LED light strips onto the acrylic
I taped the LED light strips onto the panel, and then use soldering to solder the wires in parallel circuit.
Step 3: Connecting the LED to Arduino and breadboard
I have connected the Arduino to the battery and connected with breadboard that has a switch (potentiometer). The switch would turn on and off the LED in different levels of light too. As I realized this enclosure is not portable and there is insufficient space for the wires of Arduino and breadboard to fit in the tight space with 1″ standoffs.
Step 4: Refine the design
I refine my design by laser cut several pieces to stick at the bottom, left and right side to hold the electric components. A hole is designated for the switch to go through, my first switch works and somehow it does not work after soldering. So when I switch to another switch, the switch is bigger than the previous one. It was too late after I stick the side panels and screw in the standoffs, so the switch doesn’t fit now. I added an additional standoffs to create 2″ standoffs space for putting in the components. Even though the process included lots of trials and errors, I have made the effort to make it portable LED panel which is great for photo shooting.
Advice for myself:
- measure the holes correctly for the standoffs
- learn how to buy nuts, screws and standoffs from mccarter (too many sizes and lengths to figure it out…)
- should have test out the size of Arduino, breadboard, extruding wires and outlets.
- should have use stack acrylic for exact size for breadboards and Arduino
- make dividers?
- should cut small holes at first, if not, bigger holes are unable to fix?
- make a metal sheet at the bottom to slide through the camera flash holder slot
