The 3d Printer Life

So, I got onto the 3d printing bandwagon, about half a year ago. My major sell point was I could make anything I want so I did get a nice starter printer based on the Mendel Prusa i3 from It was very cheap compared to the build boxed 1500-3000 dollar ones by Ulti-maker or Dremmel you can find at the store. For 300 dollars with shipping and handling and some elbow grease I now know for sure, this is a fine tool. As with all tools, if you take care of them they will last you long(er), and help build an unstoppable robot army(oops- I gave it away). It does require some familiarity with controllers like the Arduino, and a little bit higher knowledge of technological principles. That said, the build up from the supplied parts is real easy to do as you follow along with the pdf’s hosted by folgertech on google drive. Some idea how a 3d printer works is a plus but not completely necessary.

It started out as a box of parts and I quickly build it up like this11666205_10206745342699633_8029864577930071696_n11745312_10206768096148455_9090160351100961888_n11659396_10206751202606127_8843991176186566192_n

Longer Than Expected Hiatus

Wow, has it been a while? Well yes it has, and time moved fast. I also didn’t sit still, just didn’t write blog posts about it. So if you were anxiously awaiting another post since April I’m very sorry to have extended your excruciating anticipation. But here here, I will try my best to bring you all up to speed with my trials and tribulations of the past nine months.

You will also notice the domain change I hope this does not inconvenience you reading my posts.

I could not justify paying for a domain name since I haven’t produced anymore posts for so long.

They say that is the way of blogging unless you monetize somehow or have money to burn.

Money is not mine to burn but a little has been certainly helpful to melt down plastic and make useful stuff from it. I have been busy with the 3d printer for quite some months now and it totally fascinates me being able to design an object or even in my case a servo robot arm, which I will make write ups of in the near future.

Making music has become somewhat of an after thought but I have some new ideas to work on and finish. I’m still looking for jobs but so far none of the interviews have paid off dividends. I have become very good at talking on the phone to unknown people about just about anything really.

Well, I won’t keep you here longer than need be so see you later all

Learning With Memory Mapping or Mind Mapping

Memory mapping is a powerful technique to stimulate your thoughts, and a memory power boost.
The technique starts by drawing associations on a piece of paper. first start with the key idea or word in the center and write close by the sub ideas, then connect these with a line.

This is a powerful memory enhancing technique because it operates on a number of levels at once

Diagramming information coverts the incoming mass of data into concepts and images that are meaningful to you.
It draws on the left-brain verbal, analytic abilities and the right brain spatial, visual abilities, reinforcing facts and data simultaneously in the memory circuits on both sides of the brain.
By jotting down key ideas and indicating connections between them, you personalize the data, arranging them in a way that is meaningful to you.
Because there is always space for further ideas and connections you are prodded to keep looking in new directions.
Since the key elements are all right there on one sheet it’s easier for you to see important connections.
Consciously processing the information– rather than passively listening or reading– makes it more likely you will remember it.

Conclusion: Memory or Mind mapping is a very efficient memory boosting technique that works by involving all senses. I used it in college where I had only one class C grade and mostly B+ and A+

Rubik’s Cube and Memory Techniques, Little Journey,Loci

As a Rubik’s cube fan there is the need to memorize algorithms to solve the blessed cube. I used the loci and little journey memory techniques to memorize this algorithm for solving the top corners of the cube. The algorithm goes like this U R Ui Li U Ri Ui L, first the upper layer is turned one twist, then a right side move is needed followed by a top inverse then proceed by turning the left side counterclockwise one twist. The second part of the algorithm is the same as the first all for the second right inverse move and last move which is a left turn. Now you could say” why is it so hard to remember 8 moves?” Well,I guess it is not, but the point of this experiment was to apply some learned memory techniques and put them to the test. I decided to take a little journey through the apartment as such, by the door of the office look up U to the vent, Look right into the bathroom R, look down to the basket Ui, Walk left backwards into the hall way Li, Look up to the vent U, Look at Dusty’s cage Ri, Look down, Look at the table L. This completes the algorithm which is the standard method for solving the top corners as explained in the booklet 7 step solution that is sold with the 3x3x3 cube. Myself, I combine two methods the one in the booklet and one I picked up from You tube on the net by some Chinese dude. Ni hao!
have fun !

Sound Synthesis Visually Explained.

I remember sitting in front of the Commodore 64 around 82 as a kid, trying to figure out the modular synthesis operations possible. With its then quite advanced sound chip, a MOS technology 6581. But it’s better known as the SID 6581. I have been getting busy with some electronics and Arduino stuff lately I might just make myself a midi sound module or such based on that chip. Anyway, it was at that time a big feature one up for it’s intended market audience, the hobbyists. I was somewhat left to my own device to figure things out, mind you we didn’t have Internet then so a trip to the library was the best thing to do. To my chagrin they did not have a single book on hand. So I just did what I do and fiddled with some parameters and quite possibly invented New Wave or Emo doom! Hahaha good fun that was. But this schematic will sum it up greatly for you, know fire up that Oberheim Bristol plugin or the many classics available on Linux and throw some switches and turn those knobs!L06_a_overview-synthblock-01

Install Bind9 In A Chroot Jail

after completing these simple steps you should have a DNS Cache server running. enjoy

	apt-get install bind9 bind9-doc dnsutils

It will probably autostart after install, so stop it before proceeding:

	/etc/init.d/bind9 stop
  1. Create your chroot. This requires a minimal file tree:
    	mkdir -p /var/chroot/bind9/{etc,dev,var/cache/bind,var/run/bind/run}
  2. And some devices:
  3. # mknod /var/chroot/bind9/dev/null c 1 3
    	mknod /var/chroot/bind9/dev/random c 1 8
    	chmod 666 /var/chroot/bind9/dev/{null,random}
  4. Move your default configuration files:
    	mv /etc/bind /var/chroot/bind9/etc
    	ln -s /var/chroot/bind9/etc/bind /etc/bind
  5. Tell rsyslog to listen for log events in the chroot:
    	vi /etc/rsyslog.d/bind-chroot.conf

    and add the line:

  6. Tell bind9 init to use the chroot:
    	vi /etc/default/bind9

    and add:

    	bind -t /var/chroot/bind9"
  7. Restart syslogd and make sure it creates /dev/log in the chroot.
    	/etc/init.d/rsyslog restart
    	system log daemon: syslogd.


    	ls -al /var/chroot/bind9/dev/log
    	1 root root 0 2008-10-09 14:48 /var/chroot/bind9/dev/log
  8. Start bind9 and make sure it works
    	/etc/init.d/bind9 start
    	domain name service...: bind.
    	ps ax | grep [n]amed
    	?        Ssl    0:00 /usr/sbin/named -u bind -t /var/chroot/bind9
    	host localhost.

Now, you’re done the chroot portion. Copy over your old named.conf.local and

Line 6 products (toneport, Pod, etc..) on Linux

Tonight after laying on the couch watching the NFL division playoffs unfold all day I decided to get active 😀 some research on how to interface to my line 6 spider iv amp through the Shortboard MKII seemed like a good idea and a great little project to maybe add to, who knows? I found to be a most recent project that handles a driver module and a GUI. Support seemed a lil lacking since one person asked a question and seems yet to be answered 3 years later. But hey we all get busy sometimes , and documentation is not always priority. But here is a small helpful hint: The module or driver must first be build of course so we go to the directory $ cd ~/line6linux-code/driver/trunk do a $ make and then it should build the headers module in your kernel directory under $ /usr/source/linux-headers then we can su -c “insmod line6usb.ko” check that it was installed with $ lsmod that’s what I have checked so far, and ran into make errors for the apps ???? ok not too much on a Sunday night, goooo Packers!!!!

update: I found the driver doc here 

update: best use the mailing list for questions etc… thanks
