Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range I worked most of last week to complete my RoadTest of the TPSM84A21EVM DC-DC Converter but on Friday the revised PCBs for t...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range Over the weekend I modified the PCB design, submitted it for production, and started thinking about refactoring the firmwar...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range Over the weekend the remaining parts arrived and I finished populating the board. I found a few more problems and wil...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range The PCBs arrived today but unfortunately I was slow in ordering the more obscure parts for the design and they have not yet...
Last summer my 5 year old grandson spent the week with me and I promised his mother it would be educational and him that it would be fun. Early in the week we wired up LEDs, beepers and switches, learned about polarity, etc. We played wit...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range With the schematic complete it was time to design a PCB. This blog entry will outline the PCB design and layout along...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range The breadboard prototyping and first pass at firmware are sufficient to proceed to hardware design. After exchanges w...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range The prototype now receives AIS messages from the dAISy module and stores them in a persistent FRAM ring buffer. The r...

Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range The prototype is now receiving AIS messages from the dAISy module. In this post a method for storing the messages in ...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range In this post the dAISy receiver will be connected and the first AIS messages received.The green LED on dAISy indicates an A...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range This post will add 38400 baud UART to the existing code and test it./*
* dAISy_Alarm_V002 - adds UART at 38400 baud
* dAI...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range Now that there is a working microcontroller that runs at the right clock speed and blinks a LED it is worthwhile to outline...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range In this post I will start development of the firmware for the prototype by setting up the microcontroller's clock, sett...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within range In this post I will describe the hardware to be used for prototyping and why it was chosen.Starting in the upper left and g...
Project Objective: Develop an open source AIS Alarm that alerts sailors that a new marine vessel with AIS is within rangeTime to get back to work on the AIS project. In this post I will lay out a plan for developing the hardware and firmw...
This is a project I did with a friend just before Christmas that I was able to get my grandson involved in. The idea is to use a CR2032 coin cell to power LEDs as it rolls down a ramp. The project is constructed from foam board cut out wi...
NOTE: This is the initial post for this project. The project is now nearing completion and a chronological list of posts associated with it can be found at the bottom of the page. Project Objective: Develop an open source AIS Alarm that al...
