Importing Apple Health Data into InfluxDB

This past weekend I (finally) set up Grafana to visualize information about my machines with the usual stats like CPU usage, memory utilization, network throughput, etc. After reading up on how simple it was to add time-series data to InfluxDB, I pondered how nice it would be to also have my Apple Health data.

I wrote some Python to take the massive file that Apple lets you export (in a clunky, manual operation at the moment) and pull it into InfluxDB so that Grafana could visualize it. Check it out!

Wireless garage door opener v2

“Because my garage door doesn’t need an operating system”


I admit – I went a little overkill with the Raspberry Pi garage door opener. A machine so complex was being used to do something so simple: Perform a button press. Why did it need graphics capabilities? A multicore processor? Cron jobs? It didn’t.

Enter the Adafruit Feather HUZZAH ESP8266. All the right junk in all the right places. A simple HTTP request to the Feather, and we’re good to go.

With the recent release of iOS 10 I took it a step further. Could I get this thing to work with Siri? As it turns out, it’s really not that hard:

Raspberry Pi, touch screen, and a bluetooth speaker

A really simple project that delivers!


The only ‘gotcha’ I came across was when sending audio to the Bluetooth speaker, the emulator I was using (snes9x, the default) got super choppy. This was resolved by adding pisnes as an emulator to EmulationStation and using it instead.


I bookmark. A lot.

I’ve been working on a Python script to help me parse (and make sense) of all the bookmarks I consume on a daily basis. I was interested in just how many I accumulate daily, monthly, and yearly. It turns out, a lot.Output

3D Touch force values in Swift

We’re going to see really cool stuff from this. I was curious if 3D Touch in the new iOS devices provided continuous values, or a few discreet ones (light press, semi press, hard press).

Excitingly, you get a nice float back.

Force touch

import UIKit

class ViewController: UIViewController {

    //@IBOutlet weak var buttonOutlet: UIButton!
    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.

    override func didReceiveMemoryWarning() {
        // Dispose of any resources that can be recreated.
    override func touchesMoved(touches: Set, withEvent event: UIEvent?) {
        let touch = touches.first!
        let force = touch.force.description


Raspberry Pi Touchscreen LEGO Stand

I recently acquired a couple of the awesome 7″ Raspberry Pi touch screens. They’re great except for one thing – how the heck do you hold it up out of the box?

Some third party manufacturers are selling stands, but can dirt-cheap LEGOs accomplish the same thing? Of course. I cooked this up in a few minutes. Three points support the screen perfectly, and a piece is added behind the USB ports to minimize sliding (though that hasn’t been an issue at all).

A downside to this design is that two USB ports are blocked on this model, but you may not need them at all as in my case.

The Mac Pro gets an SSD part 2!

Welp, that didn’t take long. After installing my new SSD I quickly realized I could do better. Upgrading to SATA III from SATA II for less than $60 was a no-brainer.

Installation couldn’t be simpler either: All I had to do was attach the SSD onto the onboard slot and install the PCIe card. After powering on it booted right up, nothing else required.
