We’re moving from an apartment to a house next month, finally. The house will afford me the ability to start getting back into my eco-projects again, and I’ll be able to start posting updates and project details like I used to a few years ago. I’m really looking forward to it. I really want to focus on alternative energy, water conservation (serious drought here in Los Angeles!), and low power cooling techniques. Check back soon to see what’s new at ecoexist.net!

Replace your computer with a Raspberry Pi – phase 2

Posted by admin on Dec 25th, 2013

As promised *here*, here is the comparison between running a desktop and a raspberry pi. My raspberry pi setup is as such:

  • 2x raspberry pi’s
  • 2x external usb hard drives – one ssd, one sata
  • 1x 8 port 3.0 usb hub



Network hub is not measured in this test… Here are the results for the pi’s:

  • Time measured: 236 hours
  • Total KWH consumed: 2.34
  • Amp draw (constant): 0.14
  • Volts (constant): 120.1
  • Watts (constant): 10



Compared to the desktop:

  • Time measured: 143 hours
  • Total KWH consumed: 12.34 KWH
  • Amp draw (constant): 0.78
  • Volts (constant): 118.5
  • Watts (constant): 88



If, and it’s a big if, if the raspberry pi had an ARM v7 processor instead of the v6 then it could truly replace a desktop since then it would be able to run flash (no flash available for the v6 ARM processor unfortunately). But, as we move more and more to HTML 5 then this dependency will be less and less. As you can see, it is far more economical to run a raspberry pi – at least for the non-gamer ;)

Replace your computer with a Raspberry Pi – Phase 1

Back in February (only a few short months ago….) I stated I wanted to find out if it was possible to Replace your computer with a Raspberry Pi. I’ve been using my two raspberry pi’s since last February and replaced my former desktop, but never set about to measure the difference in power consumption – until now. I hooked up a kill-a-watt to my desktop at work, relatively comparable to the system I was using at home, and here are some of the consumption stats:

 

  • Time measured: 143 hours
  • Total KWH consumed: 12.34 KWH
  • Amp draw (constant): 0.78
  • Volts (constant): 118.5
  • Watts (constant): 88

 

Next week I’ll measure the same data on the raspberry pi’s as a full unit (i.e. both RasPi’s, usb hub, and external hardware plugged in) and update.

 

Site moves

I’ve had to move my blog a few times recently for various reasons. The last location was an AWS micro instance that just couldn’t keep up with running several blogs and a mysql server (yeah, well duh….). It limped along as valiantly as it could but I’ve finally found a new home for my blogs that will hopefully remain home for the indefinite future. It should also be running a lot better, and I hope to start updating more frequently as well.

Replace your computer with a Raspberry Pi?

Over the next few weeks I’m going to be working on replacing my full sized desktop computer, that used a 500w power supply, with a couple of credit card sized full function computers called Raspberry Pi. This little guy won’t be able to fully replace my desktop or laptop, but only because flash for web browsers doesn’t work on it because it hasn’t been compiled (nor will it ever, apparently) for the ARM V6 processor that the Pi comes with. The up side, though, is that the Pi’s are rated for 5V and .5-.7 amps – which should be well below the power requirements for my desktop.

I’m going to post a full update on what I did with them and which accessories I used. I’ll also show what the power consumption savings is by doing this. To be fair, I’m not a normal computer user…I don’t play video games usually and I run linux everywhere I possibly can. I don’t need a fast CPU generally and I plan to use multiple Pi’s to accomplish what my desktop did. Updates forthcoming.

Why, and how, I shave in the shower

“What!?!”, you may say. That sounds pretty non-eco, right? Lots of water being wasted…just down the drain. I’ve heard over and over again that shaving in the shower is bad for the environment. Well I’m here to tell you that it’s much more eco than you may think, if it’s done the right way. I’m not saying I’m doing it the best way possible, just the best way possible with the knowledge I have so far.


Here’s the jist of the thought process, and the personal results, from this “project”. Whiskers can be, let’s say, stubborn. When we use hot water they get less stubborn. The ideal place to shave, then, would be in the shower – right? All the hot water, and steam, this all makes the whiskers much easier to shave. If we make the whiskers easier to shave then the razor won’t get dull so quickly. Hopefully we’re all on the same page so far.


I have been shaving in the shower for the past 16+ years, based off of a suggestion from a co-worker back in 1994. The thing that I’ve noticed since I’ve been doing that is that my disposable razors have been lasting 2-3 months. My wife bought me a pack of 50 disposable razors from Costco almost six years ago, and I just got rid of the last one. That averages to one razor every 6 weeks. Some my wife used and some I could only use once or twice for various reasons, so the numbers might seem off, but don’t freak out over the math ;). I’ve recently been privy to information from current co-workers that they can’t use disposable razors for more than 3-4 uses. Wow. Now to be fair, I only shave every other day, and have done so for the past 16+ years, because I never seem to get a job that requires I present myself in a clean-cut fashion on a daily basis. That’s an advantage to working in the tech industry.


When I started learning about how to reduce my environmental footprint, and then started using the 5 gallon bucket in the shower (the 5th paragraph down) it made me feel like I was making a difference, albeit in a small way. My shower water collection has progressed, changed, and matured in several ways (which I’ll discuss in a later post) and now I think it’s pretty close to being somewhat mature. I collect the shower water the same as I’ve always done, but now when I shave I use a cup or mug to collect a small portion of hot water, then turn off the shower, then I shave – rinsing the razor in the water in the cup, then turn back on the shower. Because of this, I save even more water, minimize the disposable razors I put in the landfill, and get a better shave than I would if I had used the sink. Oh, and when I do dispose of the razor I remove the head from the handle and recycle the handle. I actually don’t know if I can recycle the head of the razor or not – let me know if you know the answer to that.


So what are you doing to save water? I’d be curious to hear.

Workplace eco mentality

I’m sure I can’t be the only one that has a certain level of frustration with how the general mentality of the workforce is so lackadaisical toward environmentalism. Where I work, there are several recycle bins for cans and bins for paper – but what gets put in them? Trash. Grease stained boxes from lunch, the single use coffee packets, spent non-recyclable packaging, etc. The other thing that gets me is that people will turn on every available light whether or not they need it. I’m constantly turning off two of the three light switches in the break room, which reduces the available light only slightly.

 

So because of this, I’d like to pose a question. Is it possible to motivate people to think even a little more about the benefits and need for thinking more environmentally in the workplace without sounding preachy? There are plenty of things in place where I work to recycle, and using a light switch is pretty easy, so it must just be a matter of caring. I make light comments when I see the opportunity, but it really needs to be more of a thought/life process change, than the random jibing by a co-worker to encourage green thinking.

 

Post comments if you have suggestions on effective ways to “educate”.

 

Datacenter efficiency

I’m glad to see there are more and more trends toward making computing datacenters as power efficient as possible. There are options now for lower power consumption servers, more datacenters are using solar and alternate cooling methods to further reduce their carbon footprint, and then there is Facebooks datacenter – which is described as the most energy efficient in the world. Nice. Here’s a link to more information – Facebook Datacenter.

Is it ignorance or commerce?

Last week at work, someone had put fliers on all of the cars in the parking lot. The fliers were for the 2011 L.A. Earth Fest! After reviewing the card fully, I didn’t see anything about the card being printed on recycled paper, and worst of all it was laminated so it couldn’t be recycled. I will NOT be going to Earth Fest and I would recommend people give them hell over being more about commerce rather than eco. How can an event be “Eco” with eco events when they do things like this:



Laminated Earthfest flier put on cars

No reference to even being printed on recycled paper




How environmentally irresponsible. Contact their sponsors and complain – http://www.earthfestla.org/sponsors.html

Hypermiling on a Harley – part 4

Posted by admin on Sep 18th, 2010

It’s been about two months since my last update on my Hypermiling on a Harley series. The reason it has been so long is because I’ve been experimenting with different hypermiling techniques to get as much information as possible. The conclusion I’ve come to is: so far I don’t really see any difference or benefit to hypermiling on my bike. The range I’ve seen in the last two months has been a low of about 42mpg – usually with a passenger, and a one time peak of 48mpg, but the overall average has been pretty consistently about 45-46mpg. That’s pretty much the same as before when I was just monitoring my speed.


I’m going to continue to experiment and will report any noteworthy findings, but as of this post my official series is now concluded. My suggestions? Watch the throttle and check your tire pressure – nothing groundbreaking there, but obviously very important.


*Update: it occurred to me that I haven’t added any context to my hypermiling testing. I typically commute about 48.4 miles per day round trip. Of the 48.4 miles I was hypermiling (read that as “clutch disengaged”) about 4-6 miles per day. Not a lot, but if you average that to 5 miles per day, that comes up as about 10% per day. That should translate to an additional 4+mpg, but it didn’t.
