Here is an overview of my projects. Completed projects are at the top, in progress or stalled projects are towards the bottom. Select a project for more details.
I found an interest in waterdrop photography quite a while ago. Leaving the faucet dripping into a bowl of water worked for a bit, but it was unreliable and not easily repeatable, so I decided to make this controller. It controls a solenoid valve, my camera shutter trigger, and a flash trigger. Potentiometers are used to set the interval between two consecutive drops, the period the valve is opened for (to control the size of the drop), when the camera shutter is opened, and when the flash is fired. It was a fun project for 16-year-old me and helped to introduce me to the world of embedded design. Click the button below for schematics, code, and a gallery showcasing the project.
A friend and I wanted to work on a project together, after thinking for a while, I came up with the idea for a symmetrical display cube, with an interactive display, motion reactions, and potentially some games. We initially planned on using six 3″x 3″ monochrome LCDs but we could only locate 4 from our preferred supplier, and we could not find suitable square LCDs elsewhere. Square LCDs seem to be uncommon, so we were forced to modify our design to use larger addressable LED panels. It is not what we wanted, but it will work for a prototype, and we will potentially make a smaller model using LCDs in the future. This project is actively being developed, so this page will be updated frequently. We are currently working on physical design and schematics, and will soon begin 3d printing the chassis.
Creating a nixie tube clock seemed like a good project to introduce me to high voltage DC circuits. I designed my circuit a while back, but never got around to building it as it was very tedious to solder all 10 legs for each of the 4 tubes, along with all the other wires. I abandoned the project for a while because having such a mess of wires did not seem very fun to work on, but I recently decided to get back to work on it. I am considering producing my own PCBs in my garage to eliminate as many of the wires as possible. I plan on using photoresist dry film to produce the boards, allowing with high DPI prints from my printer for the exposure. I have practiced PCB design in my Junior Design course at UCF, so I feel more confident now with this method. This project page is not complete and only a schematic will be present for now.
