Blog - TechOBrien: Rainbow Goose
http://blog.techobrien.com/2013/05/rainbow-goose.html
A life blog of myself, Sean, and my pursuits and interests. Tuesday, May 14, 2013. A little while back a friend of mine. Wanting more brightness, and a little more control over the color changing, I purchased a 3 watt from gybbshop on eBay. It's a pretty neat unit with the following features:. Aluminum-backed heatsink for dissipation. Built-in controller circuit with small SMD components. Power requirements closely matches a USB port (DC 5 - 5.5V, 150 - 600 mA). Small footprint (28mm) with mounting holes.

Blog - TechOBrien: DIY Pentax Wired Remote
http://blog.techobrien.com/2013/11/diy-pentax-wired-remote.html
A life blog of myself, Sean, and my pursuits and interests. Saturday, November 16, 2013. DIY Pentax Wired Remote. A sneak peak of the finished device. Oldschool SLR cameras used a manual linkage in the form of a shutter release cable. This allowed photographers to release the shutter without touching their camera, and a thumbscrew could also add bulb mode capabilities. A manual shutter release cable for SLR Cameras. Notice the thumbscrew for bulb mode. The nice thing about this interface is that Pentax i...

Blog - TechOBrien: The importance of "measure twice, cut once"
http://blog.techobrien.com/2013/05/the-importance-of-measure-twice-cut-once.html
A life blog of myself, Sean, and my pursuits and interests. Wednesday, May 22, 2013. The importance of "measure twice, cut once". CM Hyper-212 with two fans mounted. Both fans had rubber isolating hardware. Mounted on the motherboard. But not close enough. So to make a short story shorter, I learned my lesson. I sold the cooler to a friend and now always (sometimes) measure twice! June 24, 2013 at 2:06 AM. I missed this initial post, but saw it today.Amazing and so interesting post.Thanks!

A life blog of myself, Sean, and my pursuits and interests. Wednesday, May 22, 2013. The importance of "measure twice, cut once". CM Hyper-212 with two fans mounted. Both fans had rubber isolating hardware. I purchased this look-alike kit from eBay for less than $25. I was overall very impressed with the machining of the aluminum, and had next to no problems with the set. Sets can be found for both automatic / manual transmissions, and can be found with and without the Mazda logo. The set, all together!

Blog - TechOBrien: Caltrans Love
http://blog.techobrien.com/2013/05/caltrans-love.html
A life blog of myself, Sean, and my pursuits and interests. Monday, May 13, 2013. Early last quarter I helped clean out a storage room in the ATL here on campus. The Advanced Technologies Lab is home to some supercomputing power, machine shops, car garages, and conference rooms. While cleaning out one of the rooms, I came across this beauty:. CalTrans traffic light, complete with sun-damaged ABS plastic and a decade of dust and dirt! Find out what I did with it after the jump. Another problem was decidin...

Blog - TechOBrien: Racing Pedals
http://blog.techobrien.com/2013/05/racing-pedals.html
A life blog of myself, Sean, and my pursuits and interests. Wednesday, May 22, 2013. One very simple mod I've done to my 2005 Mazda 3 is adding "racing" pedals. These pedals do not replace the existing ones, but rather cover the ones in place. They look great, and tend to have less slippage in wet weather or with slippery shoes. The rubber covers of the existing pedals are easily removable for bolting. The set, all together! I'm thankful that my car has a fly-by-wire electronic accelerator, because I cou...

Blog - TechOBrien: About Me
http://blog.techobrien.com/p/about-me.html
A life blog of myself, Sean, and my pursuits and interests. Along with the more agricultural side of things, from a very young age I loved to tinker. Taking things apart (and not always putting them back together) was one of my favorite hobbies. Understanding how and why things worked the way they did was crucial for me, and drove a desire to learn as much as I could about whatever I could get my hands on. From there I pseudo-transferred as a Freshman to Cal Poly San Luis Obispo. I am now, as of this...
