For the final project in a class I took on prototyping methods, we could pick anything we wanted to design and build, within the constraints of the prototyping processes available to us in the lab. Our group decided to build an electric motor as it seemed like an interesting challenge. Based on a...
Here’s a preview of the PCB layout I completed for an internet connected electric vehicle charger design. Since the design requirement was only AC Level 1 (15A/120VAC) the main current paths were done on the PCB itself with 2oz copper outer layers. This simplified the high voltage front end design...
Hackaday recently featured the real time car tracker project I designed and built. The tracker uses an Electric Imp module, an STN1110 OBD-II to UART interface and a PA6H GPS module. Vehicle location and engine stats are plotted real time in Google Earth by relaying the data through Firebase to a server...
Ever wanted to keep track of how many cans of beer there are in your fridge? Want to be notified if somebody takes one? In this post I will document how to construct your very own Beer Daemon. The Beer Daemon is an internet connected device that sits above the can holder found in many mini...
In this post I will document how to interface two Tiva C Series microcontrollers over CAN bus with the Microchip MCP2551 CAN transceiver. Messages will be sent over the bus to control the second MCU’s onboard LEDs. The code for this project can be found on Github. The Hardware For this project I...
In this post I will document how to interface the PAN1321 Bluetooth module with a Tiva C Series Microcontroller and create a simple UART echo program. The Hardware The Panasonic PAN1321 is a relatively inexpensive Bluetooth V2 module that can easily be utilized by a microcontroller via a four wire...
