    Well I clearly know a lot less about circuit design than I thought. There's something wrong with this circuit, and I can't figure it out. Something about the power distribution causes the Arduino to freak out when the 12v supply is powered on and delivering power through the voltage regulator.

    I've decided to cut my losses and replace the motor control portion of this with a prebuilt relay board so that someone else has figured out all that part for me. I just bought two of these boards which can be powered from the 5v off the Arduino, and controls 8 relays. https://amazon.com/dp/B00KTELP3I/?tag=apkdotcom-20

    This will let me completely separate the power supply of the 12v motors from the power supply of the Arduino.

    Day 38. I wanted this one to be mostly piano, with just a hint of some other sounds. You might want to listen to this one with headphones for the full effect. The atonal sounds you hear are sampled from a gong. I like how some of them sound like muffled speech.

  • Day 38: New Sneaky Redirect Test for webmention.rocks #100DaysOfIndieWeb

    This was a tricky one, spawned from when sebsel failed to discover the Webmention endpoint for one of Zegnat's posts. In that case, the Webmention endpoint was a relative URL and sebsel was sending a Webmention to a URL that was also an HTTP redirect.The new test, webmention.rocks #23, instructs you to send a Webmention to a URL that is a redirect, and that page advertises a relative URL endpoint. You'll need to make sure that the URL you pass to your relative URL resolver is the final URL after following the redirect, rather than the one you start with.So give it a shot! Test if your relative URL resolution code works properly!

    It's that time again, my 8th @Jawbone is dying. Does the automatic sleep tracking on @FitBit actually work now?

    Day 37. I liked the way the maj9 chord resolved in this synth patch, so I built up the rest of the song around that. The background piano is doubled at a 1/8 step out of tune. I used the same compressor trick to help add rhythm to the background tracks too. I'm starting to run out of new video filters to use for these, I wonder how I'm going to make it to 100.

  • Day 36 - Flying

    Day 36. This one's short and sweet. When I replay this in my head I keep thinking about other embellishments I could add. I think if I later expand this I might try some of those ideas, but I didn't want to complicate this version of it. The video is from my flight from Oakland to Portland this morning.

    Today I added the h-review vocabulary to XRay. This means you may now see objects of "type: review" show up when using XRay.

  • Day 35 - Oak

    Day 35. I'm not super happy with this one. I originally had something else in mind, but didn't have the energy tonight to properly get it out of my head. So instead, you get this, which is a strange combination of sounds. You may recognize the pulsing synth sound from yesterday's song as well.

  • Day 35: Handling Redirects of Updated Blog Posts #100DaysOfIndieWeb

    My blog post from 2012 titled "OAuth 2 Simplified" is my most popular article on my website by an order of magnitude. It is referenced by over 400 repositories on GitHub, and ranks very high in searches about OAuth. I still get tweets over four years later from people who discover it for the first time and are very appreciative of finding a succinct summary of the protocol. I wrote it in 2012, when OAuth 2.0 was still relatively new, and it was based on the best practices at the time. Today I was reviewing the post, and realized that there were quite a few places where the industry standards have changed either in the terminology or in the best practices. I decided that I wanted to publish a new version of the post updated for 2017 based on what has happened in the industry over the last few years. I didn't feel comfortable updating the post at its current URL, from 2012, since that seemed like it would be rewriting history. But at the same time, I don't want to make people landing on that post from a web search or link from a GitHub repository to have to click another time to see the latest version of the post.I decided on an interesting compromise. I took the existing post, rewrote parts of it, and published it at a new URL: https://aaronparecki.com/oauth-2-simplified/I then took the old post, copied it verbatim, and published it at a new URL dated the same date as the old post: https://aaronparecki.com/2012/07/29/7/oauth2-simplifiedThe final step was creating a redirect from the post's old URL https://aaronparecki.com/2012/07/29/2/oauth2-simplified (note the "2" vs the "7") to the new URL that has no date component. (This is the part that required a new bit of code for p3k, in order to handle redirects from posts that would have otherwise matched a post permalink.)My plan going forward is to always keep the version at https://aaronparecki.com/oauth-2-simplified/ up to date, and to keep snapshots of older versions at date-based permalinks at the time when I publish an updated version. I link to the previous versions of the post at the bottom of the primary post. (Manually for now, until I decide this is an important enough feature to automate). I think this strike the right balance between providing visitors with the most current information with the least amount of effort, while still preserving the history of the older versions.

  • Day 34 - Texture

    Day 34. I started this one by listening to a Logic Pro loop that I liked. I tried to recreate parts of it as an experiment to see what it would take. I started with two synths playing the chord progression in two different octaves. I added a clip distortion filter to make them sound more dirty. I wanted them to sound like they were pulsing on the beat, except I wanted the volume to drop on the beat to punctuate the sound instead of having them get louder on the beat. To do that, I added a silent drum track that just hits a bass drum every beat, and used this as the input to a compressor so that the compressor would think there was sound on the beat and clamp down on the synth tracks. This results in the tracks getting quiet on the beat, and coming back up again on the off-beats.
