Progress on the BATMON project forms is going well. The goal is to import the existing data into a MySQL database and add onto it using form submissions. The forms will be parsed and automatically upload the data to the database. We are finalizing the lists of data needed to be included, and I will be working on learning to auto populate fields within MySQL if a survey location already exists within the database. Hoping to do this with another database table that can be searched to find existing locations, and auto populate based on a match.
ASCEND:
The carbon fiber housing has been cured, so internal components are the focus of the project right now. Both the mechanical team and the video stabilization team are 3D printing parts that will hold the internal components. Our custom PCB designs were sent to the manufacturer for printing, and will arrive March 10th. We were able to work with CustomCircuitBoards.com, who was kind enough to donate these to our project. Thank you Zack!
We are hoping to do a full capacity battery test this week or next week, where we test our main power supply and monitor the output until it runs out of juice. We will also be placing the system within a container filled with dry ice to get as close to temperatures at high-altitude as possible. I recently began taking an interest in building circuits from scratch, and ditching using Arduino all together. Using an ATTiny85 MCU, I assembled a battery monitoring tool with an OLED screen using some libraries found online. I am hoping to hook this up to the system and see if we can graph the output of the battery during discharge period. If all goes well, I can modify it in time for launch to display the state of all device within the payload, so we don't have to open the the lid.
The team is working hard to complete the payload by March 28th, so things have been very busy for all of us. I will try to take more photos!
