The project I would like to work on is a computer mouse that allows the thumb of the mouse hand to control a joystick like device. Some similar devices exist but they use a true joystick that has an awkward feel for directions. My focus is on providing better direction feel on the mouse thumb. The mouse will be built largely from scratch by integrating buttons, positioning laser, the joystick, and USB communication all with an FPGA.

The mouse will be powered through USB, the casing will be 3D printed when the product starts coming together more. The current team is 2 electrical engineers.

The joystick is a slider for analog in game left/right movement, the slider on the mouse will be roughly vertical where thumb down is left (or map-able to anything) and thumb up is right. This slider is combined with a rocking switch which has a central position as well as a pushed forward, pushed backward, and ideally pushed 2x forward for 4 digital positions. Likely project will only have 3 positions for simplicity and ease of part selecting.

Potential Parts list for providing rough idea of design:

Slider: Mouser Part # 652-PTA15432010CIB10 , OR 312-2045F-A100K OR 688-RS15H113CA05
USB Jack and cord, for example Mouser # 474-BOB-12700
Rocker switch ideally is of (ON)-OFF-(ON) type, few cadidates also from Mouser. Also have seen several multi (4+) position slider switches, but these seem less desirably for the feel.
FPGA - have not selected however have experience in Vivado with Artix 7 chip from ECE 437 using an Opal Kelly dev board. Not sure what is allowed as has as if it is ok to start with a basic board and integrate another board of our own design into the project. One possible
Otherwise my requirements for the FPGA are probably not to difficult. Able to receive a few discrete signals from the rocker switch as well as an analog value from the slider. Will need to confirm voltage levels with the slider are compatable with FPGA. Also FPGA will need to be at lease USB 2.0 capable (as far as speed).
Optical sensing for mouse can be done from scratch or preferably with a board such as where all that is needed is SPI communication to FPGA.


Cloud-controlled quadcopter

Cloud-controlled quadcopter

Featured Project


To build a GPS-assisted, cloud-controlled quadcopter, for consumer-friendly aerial photography.


We will be building a quad from the frame up. The four motors will each have electronic speed controllers,to balance and handle control inputs received from an 8-bit microcontroller(AP),required for its flight. The firmware will be tweaked slightly to allow flight modes that our project specifically requires. A companion computer such as the Erle Brain will be connected to the AP and to the cloud(EC2). We will build a codebase for the flight controller to navigate the quad. This would involve sending messages as per the MAVLink spec for sUAS between the companion computer and the AP to poll sensor data , voltage information , etc. The companion computer will also talk to the cloud via a UDP port to receive requests and process them via our code. Users make requests for media capture via a phone app that talks to the cloud via an internet connection.

Why is it worth doing:

There is currently no consumer-friendly solution that provides or lets anyone capture aerial photographs of them/their family/a nearby event via a simple tap on a phone. In fact, present day off-the-shelf alternatives offer relatively expensive solutions that require owning and carrying bulky equipment such as the quads/remotes. Our idea allows for safe and responsible use of drones as our proposed solution is autonomous, has several safety features, is context aware(terrain information , no fly zones , NOTAMs , etc.) and integrates with the federal airspace seamlessly.

End Product:

Quads that are ready for the connected world and are capable to fly autonomously, from the user standpoint, and can perform maneuvers safely with a very simplistic UI for the common user. Specifically, quads which are deployed on user's demand, without the hassle of ownership.

Similar products and comparison:

Current solutions include RTF (ready to fly) quads such as the DJI Phantom and the Kickstarter project, Lily,that are heavily user-dependent or user-centric.The Phantom requires you to carry a bulky remote with multiple antennas. Moreover,the flight radius could be reduced by interference from nearby conditions.Lily requires the user to carry a tracking device on them. You can not have Lily shoot a subject that is not you. Lily can have a maximum altitude of 15 m above you and that is below the tree line,prone to crashes.

Our solution differs in several ways.Our solution intends to be location and/or event-centric. We propose that the users need not own quads and user can capture a moment with a phone.As long as any of the users are in the service area and the weather conditions are permissible, safety and knowledge of controlling the quad are all abstracted. The only question left to the user is what should be in the picture at a given time.
