The official one month count down to UPEW 2011 @ Parallax is about to begin!

The expo starts Saturday morning & does not close until 4pm the following day!

Parallax will remain open ALL NIGHT for Propeller projects & collaboration.
===============================================================

* Have you had been so busy that a Propeller project has been suffering from neglect?
* Have you had a project that has been on the todo list for far too long?
* Would your project benefit from live collaboration and help?

Bring it with you for project time during the wee hours of the morning at Parallax!

Collaboration in the forums has created some awesome projects which have benefit everyone, post up what you'll be bringing and you'll likely have several folks ready to lend a land!

What?!!?! You haven't signed up for UPEW 2011 yet?? http://www.propellerpowered.com/expo

    I'll kick this off:

    My dual Propeller video code and Propeller gaming has been suffering from neglect due to some deadlines I'm working...

    So I'll be working on both this and this..

    Here's an example:

    I brought the Star Wars Force Trainer last year. Collaboration between Beau Schwabe, Stephanie Lindsay, and myself. While the concept itself wasn't a success, it was a great overnight UPEW project.

    As far as working late on a project, I have a differential (or binocular) version of this in mind ultimately for triangulation ...

    http://www.youtube.com/user/ICPolyman#p/a/u/2/afv2wviU51Q

    ...In the video, the Infrared Receiver is configured in an analog mode with the output connected directly to the scope.

    ...Or I could be helping Jeff out and scrap the whole IR thing :-)

    I'll be working on my balancing robot (prop based with parallax sensors), my pinball machine, and another bot base that uses mechanum wheels I got from Sparkfun.
    I'll also help out wherever I can...

    I haven't been too satisfied with the IR keyboard so I might be working on interfacing my TI keyboard to the DVD player. (In fact I'm thinking of re-opening the photo frame again and adding a jack for this.) The TI keyboard is expensive but it's very small, very typeable, very rugged, self-powered, and has seemingly infinite battery life with normal AAA batteries. Unfortunately, the TI calculator NoteFolio app drops characters. I know this is the app and not the keyboard because under certain conditions, such as when the calculator is doing a garbage collection (ironic that) the calc records high-speed keystrokes flawlessly. The problem there appears to be the calculator LCD screen driver, and I got just far enough into it to realize I didn't feel like fixing the problem on that platform.

    So I will eventually be trying to fix it with a Propeller. Anyone done any TI bus code for the Prop?

    BTW I'm forming a theory that the Ativa photo frame only uses about 75% of the scan line for pixels because they used the same board and timing for a larger screen product. Anybody think I should spring for their next size up frame to see? (Answer as if you'd be spending your own money plz kthx)

    Since I work with Parallax full-time, could I be granted a variance to the theme and bring an amplifier that needs to be repaired? I have a Sonance amplifier that clicks here and there before shutting down. Chris Savage was going to take a look but I loaded the guy down with too much work. I know that many UPEW attendees could look at my amplifier and solve the problem really quickly.

    What do you think, OBC?

    Also, I have a set of underwater thrusters that I'd like to test via their ESC over an XBee link (yes, the craft's electronics are above the waterline).

    My opening approach to all SMPSUs is "replace the small(ish) cap on the HV (to us normal(ish) folk, or LV to modern people) side of the SMPSU.

    Please disconect the power source before, or at least post pics of the results afterwards, laughter may (will) result.

    Most of the designs have a 1 - 100 uF that is either dried up, or the PSU is probably so completely banjaxxed that all hope should be abandoned.

    Thanks Toby. I think the power supply might be a bit toasted, as it works for a while then it begins to fade. Well, I'll recruit some of the UPEW brains around here to take a look with me since I have a good ability to banjaxinate these things with pops and smokes when working alone. My analog ability is pretty much limited to dealing with people aside from using A/D converters. . .

    Ken, because you are our gracious host, we'll let you bring it. :) I was considering making you put a Propeller beanie sticker on it, but a Sonance amp is simply too nice for that. :) Are you still bring your other more Propeller (flying) project for the overnight hack?

    Starting to finish off a couple projects so that I can prep for my UPEW project plans. Here is where my list stands now:

    1) On this thread, I mentioned a low cost wrestling timer from some discussions with my brother who coaches high school wrestling. I spoke with him some more on Friday and phase one is a go: Make a small wrestling timer that outputs either composite or VGA video with a standard high school level wrestling scoreboard and timer. Will consist of two scores, a clock, and period marker. Should be a simple use of the VGA/TV text drivers, but the interface needs to be easy to use and the "clock" code needs to run backwards.

    2) Brainstorm with others on writing a Propeller based recreation of the classic Mastermind game

    3) Fix the distance portion of Abel's Handheld GPS code for my version and get the keypad working.

    4) Symbol LS1220 Barcode Scan engine utilization. Microcontrolled has the foundation fro this done, but I need to resolve my needs for him/me to take it to the next step.

    5)
