Raspberry Pi

| August 14th, 2012

So I made this case. And the Pi fits in there pretty good. I did have to notch out the bottom to make room for the USB connector to poke out (not shown).

I’m also working on a reset switch for the Pi because it does not seem to a have hardware switch that will cause a proper shutdown of the OS.

Since it seems there is no command line spice packaged with the free pspice/orcad 9.1 student edition I decided I needed to figure out how to make it work, and I did. After much googleing, and failed command prompt switches, I figured out that the only (useful) switch that pspice would respond to on the command line is -c. Which basically allows the user to run a script against the UI after pspice AD is executed. The program loads visually, does it’s thing and then closes. That’s as good as I could get with the free stuff. more »

Atmega85 with AVRDragon

| April 19th, 2011

I just loaded a basic pin toggling c program to test my AVRDragon chip programmer. Apparently at some point I had figured out how to re-wire this tutorial on instructables to work with the 8 pin chips.. two or three Halloweens ago. It was the night that Dave Bazan played the Slowdown as not Pedro the Lion. Well anyhoo, to my surprise it actually worked! Pin 7 was blinking like mad. So I guess next is this LCD character display setup once the shift registers come in the mail. I suppose with 8k of program memory I’ll act spoiled and write in c? Well, I might try some assembly after all.

I think the title really says most of it already. I have been working on 8086 assembly stuff for a class. We are using DOS and MASM a lot. My friend Kyle and I wanted to share the source for our project but neither of us had a good idea how to do it. We both have google docs accounts so for this last project we just shared a collection with two folder OLDARCHE and NEWEST. To check a file out we just moved it to OLDARCHIVE. Then to check it in we just copied it back up. Since you can download whole collections as a zip file this worked pretty well. more »

I’d say buy one just because. I think it rules. It’s at least a good web browser that fits in your man purse. It’s plays you tube etc… And some how it knows where I am in the google map. I read some reviews where people cry about it not being everything it was advertised to be. HELLO THAT’S CALLED ADVERTISEMENT! IF YOU DON’T LIKE IT AND YOU LIVE IN THE USA TAKE IT BACK TO THE STORE FOR A FULL REFUND AND SHUT IT. PS: naked chicks

PDF what?

| July 15th, 2010

How do you split the pages in half? If you had a PDF and you wanted to split the pages each in half and have twice as many half dimensioned pages how would you do it… Sadly the answer is perhaps to print the pdf to file with crazy print options. AFAIK there is no functionality in Adobe Acrobat Pro that lets me cut off the bottom half of each page and move it to a new page just below that one for each page. WHY would I/you ever want to do this…. well the PDF reader I have was being real lame about what it wanted to do so I had to feed it a gourmet PDF. Because I wanted to read the document in landscape mode… I had to rotate the PDF in an editor… but I also only wanted each half a page to be a page. DOES ANY OF THIS MAKE SENSE!!!! formatting PDFs for a specific screen size is a pain! But who wants to scroll? So it must be done. Text layout jams and flow are still related to the size of the medium. I know there are technologies that are suppose to be agnostic of that but there will always be things like diagrams or graphs that have to contain a certain amount of detail.. or lack of detail which is sort of up to geometry a little bit. Panning / scrolling makes me want to vomit a little less that zooming way out so that the whole figure is visible but without the detail. In the mean time I’ll be wasting time trimming, rotating, and gutting PDFs like the rotten fish of a medium they are.

I was trying to to a quick add of a repeating event. After a bunch of trial and error, SUCCESS!!
I think the toughest thing to figure out was that the event will not repeat if you do the quick add and do create event without first clicking edit event details.

In other words if you want the event to repeat … you must click edit event details.

Which is to say even if you enter the syntax exactly right the event will not repeat! Am I carzy?

Well… it wasn’t pretty. I had once had some things from amazon sent to my friend in England. Because I had one address in my address book it would not let me download anything.

“We could not process your order. The sale of MP3 Downloads is currently available only to US customers located in the 48 contiguous states, Alaska, Hawaii, and the District of Columbia.”

Every address I have ever lived at in the last 8 years or whatever is in there and because I had some thing sent to the UK I can’t buy mp3s…? I deleted that one address and every thing worked… OH but before that… I could not get the installer to work because it only wants to work with 32 bit.

The dell I’m on is a 64 bit guy with the 92xx sound card from singmatel audio.

BOOOYAAAHHH

Dell might tell you that the hardware feature is missing.
According to … oh, wait it works. You just need an old driver. Why would an old driver work better than a new one? I don’t know ask DEVO, the band. Maybe they know something I don’t.

Go forth and find the driver R171789.exe from dell.

I have renamed the file on my system to:

“R171789_GOLD__92xx_32and64_bit_stereo_mix
_recording_driver__run_with_xp_compatability_
_after_unistalling_old_driver_BUT_BEFORE_REBOOT.exe”

You should un-install all audio drivers (make sure they are really gone). Then install this bad boy and reboot.

use the XP sp3 compatibility mode in properties when you run it!

also you need to right click in your recording devices and ‘show disabled devices’ AND WANG THERE YOU GO!

It might work in Vista and Xp as well?

mobility center

I thought the mobility center available in windows 7 was going to revolutionary my life. I really thought that by striking the keys

WinKey + X

I was going to have access to all the controls that were most important to me. Turns out I have instant access to all the controls Bill Gates thought I would ever need, with no options to add my own choices such the microphone volume/gain. I can adjust my speaker volume BUT NOT THE MIC. OH THAT’S RIGHT… I’M JUST A DUMB CONSUMER WITH NO BRAINS… WHY WOULD I NEED A MIC!!!!!!
I’m SURE it can be done SOMEHOW. But no instructions are given here:

“Some tiles in Mobility Center are added by your mobile PC manufacturer” BUT NONE WILL BE ADDED BY YOU!!!!

Sit back and enjoy the show friends! Sorry to harsh your vibe. :p
