The proposed aquarium water chemistry control system combines affordable DIY sensors and a microcontroller (ESP32 or Raspberry Pi Zero) to monitor key water parameters and automatically dispense nutrients. Using IoT technology, it enables real-time data tracking and remote management. This solution addresses a market gap by offering an integrated, cost-effective alternative for hobbyists, hydroponic growers, and small-scale aquaculture operators who currently lack accessible, all-in-one water quality management tools.

At Design Build Fly at JHU, we compete in the annual DBF competition, where universities around the world design, build, and fly custom remote-controlled airplanes to optimally complete missions. This year, we placed 49 out of 159 teams, putting us in the top third of competitors! We’re very excited with our placement and improvement over last year, and can’t wait to build a better plane next year!

Urostomy is a type of urinary diversion that reroutes urine flow through the creation of a stoma. Current urostomy interventions often cause discomfort and impact on patients’ work abilities and social activities due to issues such as leakage, body appearance, odor, and skin irritation. Many of these issues are rooted in the design of urostomy appliances, highlighting the pressing need for an improved urostomy intervention that addresses these multifaceted challenges amongst urostomy patients.

We present a novel pouching system comprising Stomify Baseplate and Stomify Pouch. Stomify Baseplate integrates a leakage absorption and detection mechanism allowing user to check for leakage during routine pouch emptying every 2 to 4 hours. Stomify Pouch is designed for flexible orientation, enabling users to wear it both vertically and horizontally without flow interruption due to external pressure from clothing.

Opioid addiction is a huge problem in the United States that is destroying lives. Millions of Americans suffer from opioid misuse, and millions are seeking treatment through addiction-curbing medication such as naltrexone. Currently, naltrexone is delivered through an oral pill or an injected device. Patients on oral naltrexone tend to have less retention to the drug because of withdrawal symptoms, but it must be taken daily since naltrexone absorbs quickly in the body. The injected form remedies this problem through continuous release, but it is expensive, invasive, and requires periodic check-ins.​
​
We propose NaxPatch, a microneedle patch that can continuously administer naltrexone intradermally. It can be placed on the upper arm and worn discreetly. It would also be replaced once a week, which fits many schedules and is hard to forget. We believe NaxPatch will be a cheaper alternative form of naltrexone that is safe, effective, and convenient.​
