"With all these negative reviews, I thought it would be hard to get going, but I'm no slouch when it comes to technical stuff so I gave it a try. It was really pretty easy. I got it to work with two different raspian images (hypriot and the standard Jessie) by just adding a few lines to the config.txt:
max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt=1024 600 60 6 0 0 0
The first line let's the pi send it more current over the USB ports, the other three set a manual resolution for the HDMI. These are standard pi configuration variables, and needed for most bare monitors." -
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 39: Including a Featured Photo when Syndicating an Article #100DaysOfIndieWeb
I've noticed a pattern in the blog posts that I write about these #100DaysOfIndieWeb updates, which is that I almost always include a photo in the article, most of the time embedded in the text. When I syndicate these articles to Twitter, I was previously only including the name of the post and the URL to the post, but I wanted to include the photo as well.Today I updated my syndication code to check for a "featured" photo when syndicating blog posts. It first checks for a "featured" property in the post's storage file. (So far I don't actually have any examples of storing it that way.) It then parses the post's HTML and checks if there is an image with the "u-featured" class. If so, it includes that image in the request to syndicate the post via silo.pub.Now my syndicated articles will include an image!continue reading... -
Day 39 - Escalation
Day 39. I don't know if you can really call this one a "song". This is an attempt at making something that could be used in a trailer or as the end of an episode of a TV show. There is a base track of a few layers of string instruments, and then I layered a whole bunch of other sounds to build up to the big "boom" at the end. I reversed a couple of the sounds so that they build up instead of taper off. There's also a heart beat at the super low frequencies that doesn't actually follow the rhythm of the rest of the piece, which I think gives it a nice bit of dramatic effect. This time, I was mixing it while listening on both headphones and my desk speakers to make sure it comes across okay without headphones.continue reading...
