Here is the image capture from my scope. It's at 52.95V RMS, and 152V peak-to-peak @ 60.1Hz
It looks like its ~250V sine wave with the top flattened off.
And it won't grill my sandwich:(
I just measured 36.8VAC @ 60Hz between a chassis screw and plug ground on a Dell Inspiron 15" Latitude D820.
Perhaps I'll put it on the scope after lunch. I wonder if it will grill my sandwich?
We use the Handyboard http://handyboard.com/ which is kinda old-tech with a Motorola 68HC11, but is very beginner friendly. There is a free C compiler available http://www.botball.org/educational-resources/ic.ph p that is also very easy to use. With the expansion board there are many interfaces: analog inputs, digital in/out, sonar, motor drivers, servos, LCD screen.
What if there are not enough machines to fill the pre-orders? I could see this being very likely with the cuts that were made already. Then it will be first come first served for the pre-orders, hence the folks in line.
Just last Tuesday I participated in a driving experiment in a 360 deg field of view simulator. It mostly involved cruising straight through intersections and looking for changes. However, at the end of this long road we had to turn around and come back. The sensation when braking and turning is amazing but not very enjoyable. It was an instant wave of sick but was only temporary. I only get motion sickness while reading in a car, but this was an instant trigger. At the end of the experiment I asked to do some fun drifting in the parking lot and could only last about a minute before getting too dizzy to carry on.
[And that "touch pad" on my portable, more than once I have thought about taking an electric drill to it to destroy it.]
Many times I've caught myself using the touchpad with my wrist bent backwards as far as it goes and middle finger straight down sliding around. I look down and think, "What the hell am I doing".
I would think "awareness" is one of the biggest preventers of RPI. You just have to train yourself to think before you type. Usually it only takes 2 or 3 seconds to get into a better position.
They are actually behind their goals for releases. I've read elsewhere that it should be every 6 months.
"Produce robust releases approximately 2-3 times per year, using a time-based release model: A time for a feature freeze is set in advance, and an expected schedule for test releases is produced before the feature freeze date. (Important feature schedules will be taken into account when setting the schedule for Fedora Core releases.)"
I've had some luck with the Netgear WG511 and Fedora Core 4. The prism54 driver is built into the current kernels. The only thing required is the firmware (which is easily found on the net) and copy it into/lib/firmware
I am currently in the process of migrating from windows XP Pro to Fedora Core 4 on my laptop. Even if I give up later on, I have learned some what I actually use my laptop for. I went through and kept track of what I was doing for a few days. Turns out that everything I normally do can easily be done in Linux: -sync palm -copy music to SD card- -read email -check calendar -surf web -instant message -wireless connectivity -3d games -read pdfs -read and edit excel/doc files -listen to music -watch the occasional video.
After some setup and tweaking-- I can do all of the above in a much more friendly UI.
The biggest help in the transition is that I can dual-boot and also that I can read from the NTFS partition in the process (for documents, music, videos, and pictures) using linux-ntfs.
Now I know what those USB ports are doing on my Bell ExpressVu(BEV) 9200 HD-PVR (equivalent to a Dish 942). They are labled for 'future use' in the manual. I hope BEV does something similar, or at least enables the ports to download content to my computer.

D'OH! I mean.. its been a fun couple of months, but when I read this I realized the hour or 2 I spend in front of the TV(with my laptop) may be the culprit.
Not just the $100s are affected..

.. many places in southern Ontario will no longer take $50 bills, and those that don't often have the UV detectors. Sometimes if I take out a larger sum of money out of the bank machine, I'm peeved that I have to deal with $50s.

This means that the initial takeoff shouldn't be as difficult as expected if the pitch of the blades is controllable. The pilot can get the rotors spinning more freely, pull on the 'collective' (blade angle control) and the momentum of the rotors will help pop it into the air. The problem I see is that the energy required to spin up the rotors doesn't count towards the timed flight, so once you're in the air you're already at a disadvantage.

Why aren't these cards passively cooled? They're a generation old anyways. If they're marketing it for HTPC, then they missed a big selling feature.
Just finished my call with Dell (Canada) and they're sending out 3-prong adapters.

I'd like to hibernate until the hardware to run Doom3 at full detial is plentiful and cheap. Say 3-4 years?
