Ten years ago, SpaceShipOne proved commercial spaceflight could be a reality

Back in 2004, companies weren’t fighting over NASA contracts and nobody was selling tickets for suborbital space flights just yet. The commercial space industry was still in its early stages …

Personal projects and self-hosted tools

A recent scroll through my blog posts got me thinking about the personal projects I’ve worked on in recent years. Last month I built my own wifi router over a three week period. It was invigorating. Similarly hardware-related, I came across a three-year-old blog post from when I built my current desktop PC. It still meets my needs quite nicely so I’ve no need to upgrade, which is a nice feeling. On the software side, a much older project is a web application I call Tracker. It’s something I use roughly 355 days a year.

beagleboard-xM Wifi Router

For the past year I’ve been using a TP-Link WDR4300 wireless router. I tried installing OpenWrt on it but it became unusable so I reverted back to stock. Last month I decided to build my own wireless router out of the beagleboard-xM I bought three years ago.

What are the benefits of building my own router?

  • It could provide network attached storage via a USB drive or MicroSD card. Could use something more robust than the FAT filesystem too.
  • It uses less power by 3 watts. 5v @ 3A compared to 12V @ 1.5A. I think this comes out to a savings of $2 per year.
  • The Beagleboard with an external USB wireless adapter is slightly smaller than my current router
  • When new wireless technologies come out (like 80211ac) I could simply buy a new USB wireless adapter rather than having to replace the whole unit.
  • With 4 USB ports, I could add extra wireless adapters to cover the 5Ghz spectrum

TL;DR version of all the hurdles I encountered along the way:

The National Park Service tells the Associated Press that it’s about to order all 401 of its parks to ban unfettered use of drones on their grounds.

I kinda want a drone, or some sort of flying radio-controlled vehicle of my own, but nevertheless I’m quite happy about this.

Donated to somafm (internet radio station)

Today I gave money to support Soma FM. iTunes radio is starting to remind me of Pandora with it’s repetition (and ads!), so I figured I should support Soma FM and add them back to my rotation. They’re ad-free and they keep adding stations … kinda blows my mind.

Learn how foreign aid reduces overpopulation, dependency on aid for impoverished countries, and makes a sustainable future for our planet.

This letter is a great read. It invigorates my optimism. “In just 25 years, new cases of polio were reduced from 350,000 annually, to less than 400 in 2013.” Simply, wow.

Wow:

* The moon is rich in rare-earth elements. Sounds kinda funny when you think about it. The moon is rich in unrare-moon elements.
* There is a US rare-earth element mine, and it has recently opened back up. If only mining had fewer long term environmental risks.
* And of course, recycle your cell phones.
