Nanoparticle Carrier Blood Brain Barrier (BBB) penetration Nanoparticle Carrier Blood Brain Barrier (BBB) penetration So I'm just starting this project and would like to know a couple of things. 1: Is this feasible? I don't know if I as a high schooler can do these things, especially since I plan on using computer sims. 2: If you guys have experience in computational biology projects or just computational projects, what would be my best bet in finding a framework? I've found some mock… Read more

Advice for solar physics project Advice for solar physics project Hi! I am a grade 11 student, who worked on ICME research(interplanetary coronal mass ejections). These events pose a profound threat to the technological-modern world. Critical systems, including major communications networks, satellites, electric grids, and crucial electronics, can cease to function and be permanently damaged by space weather events. Therefore, it is essential to better understand the evolution of these… Read more

Artificial Pancreas Artificial Pancreas Posted on behalf of student/family -------------------------------------------- My daughter is building this artificial pancreas project for a science fair. We followed all the trouble shooting and made sure the pump(5-6) works when connected directly also using a button. But the pump never turns on when using the connection for this project with output from A0, We tested using the MOSFET for turning the pump on as well. Any help on troubleshooting… Read more

Issue with right IR sensor on Bluebot Car Issue with right IR sensor on Bluebot Car The Right sensor does not seem to be detecting anything. We did run serial monitor and the Left IR changes value when approaching line - Right stays around 950 and never changes when placed on the line. We have switched the right and the left sensor to verify the sensor isn't bad and it failed on that as well. The right IR is A1 and and left is A0 - does this mean we have a bad connection? Re: Issue with… Read more

Clinostat: Arduino UNO R4 Minima won't run code Clinostat: Arduino UNO R4 Minima won't run code So I'm in a Science Fair and I've been trying to get my code to run on my Arduino. The code is in the "Grow Plants in Microgravity with an Arduino Clinostat" and I have already put in the code it just won't run. The computer I'm using is a Pixelbook Go. According to what I watched the code should execute when I put in the code but when I have wires attached to the Arduino it wouldn't connect to… Read more

Microsoft Hardware Engineering Intern Interview Microsoft Hardware Engineering Intern Interview Hello, I was wondering if anyone has interviewed with Microsoft for a electrical (hardware) engineering internship before? I'm not entirely sure what to expect. In the email my recruiter sent, he said to be comfortable with computer science fundamentals, OOP, and data structures, which I feel fine with but I thought it was a bit strange since I thought it would be more hardware focused lol. . Any… Read more
