Projects

✔️ Task:

• The experiment consists of a fixed 137Cs radioactive source and a detector that turns around a target to detect the scattered photons by that target.

• Automate the detector placement to reduce the radiation dose received by students.

• Remotely view and control the experiment.

📈 Results:

• Detector position and source exposure are now remotely controlled via TCP/IP network. The experiment can be monitored remotely through a camera inside the experiment room.

• 100% reduction of radiation dose received by the students;

• 37.5% reduction in experiment execution time;

🏆 PAEPE Award 2014 - The best project of Physics Institute

🤝 Team project

👨‍💻 My contribution:

• design and assembly of the positioning motors.

• design and assembly of the electronics for motors and actuators control.

• design and programming of the remote communication system.

✔️ Task:

• Develop a simple tool for processing spatial and temporal information in an automated fashion from wound healing and scratch assays.

📈 Results:

• PyScratch offers a user-friendly interface allowing researchers with little or no programming skills to perform quantitative analysis of in vitro scratch assays.

• Since your publication in 2020 Pyscratch becomes a worldwide used tool that helps biologists in the daily routine.

🤝 Team project

👨‍💻 My contribution:

• Design and code the data analysis.

• Design and code the user interface.

• Make the repository and maintain it.

✔️ Task:

• Develop layer-by-layer deposition equipment for thin-film construction.

📈 Results:

• The equipment performs an automated layer-by-layer deposition of "mono-layer" or "bi-layer" films.

• The equipment can be set via software via USB cable or via buttons and LCD display.

• The software "DipCoatingController" was also developed as part of this project.

• The 3D printed parts were also designed within the scope of this project.

• There is a hardware option for single or multiple depositing up to 4 plates.

👨‍💻 Solo project

✔️ Task:

• Monitor CO2, humidity, and temperature levels in a cell culture incubator.

• Alert lab users if any of the levels exceed the limits.

📈 Results:

• The Raspberry Pi-based hardware receives via USB the CO2 level, humidity, and temperature values.

• The Raspberry Pi hosts a web page that displays graphs of measurements from the last 24 hours. The site can be accessed by any user on a University network.

• Was also developed within the scope of this project a virtual machine on the University's server. The VM communicates with the Raspberry Pi to get the latest level information. The VM also controls a Telegram bot that communicates with users in case of an alert or error.

👨‍💻 Solo project

✔️ Task:

• Develop a simple-to-use tool to assist in electronics lab classes.

• Design the signal capture interface with an oscilloscope.

• Design the communication interface with a signal generator.

📈 Results:

• Since its release, PyLab has been used daily in experimental electronics classes in the teaching laboratories of the Institute of Physics.

• The increase in data acquisition speed revolutionized the way experiments are performed, improving the didactics of experimental classes.

• Pylab can control both signal generator and oscilloscope and has pre-programmed routines for FFT acquisition, frequency response, and temporal response.

👨‍💻 Solo project

✔️ Task:

• Sort hundreds of resistors by value.

📈 Results:

• OhmSorter sorts the target resistor into one of four possible values. The operator places the resistor in the box corresponding to each value.

• It is possible to add more value cases. I chose 4 because it was visually easier to sort.

👨‍💻 Solo project

Task:

• Make beautiful stop-motion-like videos of 3D prints.

• When you try to make a Stop Motion of a 3D print from a film or just take a set of pictures the nozzle is in a different position on each shot, heaving a not-so-great result.

📈 Results:

• Set of circuits, codes, and parts to generate awesome Stop Motion videos of your 3D prints.

• The solution is to sync the camera with the printer.

• In this project, I handle three differents approaches tho have a nice Stop Motion of a print.
