Over a year ago I participated in the <a href="https://www.kickstarter.com/projects/1598272670/chip-the-worlds-first-9-computer/description">kickstarter campaign</a> for “CHIP - The World’s First Nine Dollar Computer” by <a href="https://www.nextthing.co/">Next Thing Co.</a>. I went for the PocketCHIP because of the idea. Display, built-in storage (thus no need for SD cards), battery-powered, and a keyboard are pretty nice features. Last week a package arrives…</p>

<p><a href="https://github.com/rhooper/">Roy Hooper</a> did an amazing job migrating the history support from being tied to SQLite to use the ORM SQLAlchemy instead. This means that you can now use <strong>any</strong> SQL backend for the history. So besides SQLite you can now databases like MySQL or PostgreSQL. However, this does require that you install <a href="http://www.sqlalchemy.org/">SQLAlchemy</a> and run a command to migrate your existing history over. We tried to make the process as seamless as possible by introducing a new command line script:</p>

The first release of Micropython for ESP8266 was delivered a couple of weeks ago. The <a href="http://docs.micropython.org/en/latest/esp8266/esp8266_contents.html">documentation</a> covers a lot of ground. This post is providing only a little summary which should get you started.</p>
<p>Until a couple of weeks ago, the pre-built MicroPython binary for the ESP8266 was only available to backers. This has changed now and it is available to the public for <a href="https://micropython.org/download/#esp8266">download</a>.</p>
