Blueprints Make It Easy To Make (Some) Alexa Skills

Posted on by

If you can code, you can create an Alexa skill — the programs that allow an Amazon Echo or similar device interact with you. What if you can’t code or you are just too lazy to do all the setup? Amazon now has Blueprints that can help anyone make a skill. The only problem is the skills you can create are pretty limited. In addition, they are only available to your Alexa devices.

The idea is simple. You start with a template — OK, a blueprint. This is a model application that does something like giving you a compliment or …read more

It uses a UBlox NEO-6M positioning module for the location and a custom built QFH antenna built after calculations done with an online calculator for the GPS half. The audio half is based around a VLSI VS1003b decoder chip.

Electronic Message In a Bottle

We remember going to grandfather’s garage. There he would be, his tobacco pipe clenched between his teeth, wisps of smoke trailing into the air around him as he focused, bent over another of his creations. Inside of a simple glass bottle was something impossible. Carefully, ever so carefully, he would use his custom tools to twist wire. He would carefully place each lead. Eventually when the time was right he would solder. Finally he’d place it on the shelf next to the others, an LED matrix in a bottle.

Well, maybe not, but [Mariko Kosaka]’s father [Kimio Kosaka] has done …read more
