Jason Client

“Jason is a scriptable iOS client that lets you view and interact with any data and any server, in any way you desire.” Basically, you feed it a JSON config file which describes a UI and data sources. The client then consumes those sources and displays them according to your UI definition. And you get access to device-native APIs, too.

Project time

I’ve been tinkering a little bit with my electronics stuff again. Now I’m trying to decide on a project to do, and which hardware platform to use… I have a ton of different microcontrollers — Digispark (ATtiny85), Digispark Pro (ATtiny167), Digistump Oaks (ESP8266, wifi), Adafruit Trinket Pro (ATmega328), PunchThrough Bean (BLE), Particle Core (wifi) / Photon (wifi) / Electron (3G cell), NodeUSB (ESP8266, wifi), ESP201 wifi  modules, some Arduino Pro Mini clones, a Tessel2 (wifi, linux, JavaScript), RFduino (BLE), and a few others that I can’t even remember right now.

  • TV Mute Button
  • WiFi/Bluetooth control for our garage door
  • Motor push-assist for our son’s wheelchair
  • Distributed temperature sensors tied to our thermostat
  • A mailbox sensor to notify us when we have mail
  • Some under-cabinet lighting using addressable RGB LED strips
  • Phone push-notifications from our doorbell
  • Tying into the security system panel and sensors in our house
  • RGB reactive lighting for my car (audio spectrum, etc)
  • Homebrew robot or quadcopter

I suppose the first thing should be to finish up the TV Mute Button I started to build for our son a while back. But as you can see, I have plenty of possible choices. I guess I’ll start small and work my way up. 🙂

 

chartd

chartd makes it easy to include charts (either png or svg) on your web site, by just passing parameters in the URL of an img tag. For simple charts, this will be easy-peasy to automate. Of course, the downside is the same as for any other time that you let a third-party service have responsibility for your content — what if they shut down the service?
