Re: [Sugar-devel] Interesting USB-pluggable robots, controller boards, and sensors
It sounds like what is desired is an update of a 10+ year-old thing I helped design called MIPPET -- Module for Input/Output Programming Projects Enhancing Teaching [1]. The interface we used was the parallel port, which made things easy at the time since USB 1.0 was in its infancy. There was talk even then though of possibly doing a USB update, and we had a USB 1.0 development kit I played with a bit. This was never mass sold to my knowledge, but I could try and research if any progress has been made on the USB update. If not I could attempt it or nudge other people to try and do so, although if this turns into someone's college project I would not expect to see a result until the fall semester. (Extra credit goes to anyone who can figure out what MIPPET actually stands for and not the backronym the professor came up with. It's not too hard to find, so I'm not certain what it will get you.) [1] Described a bit in the document at http://www.rowan.edu/mars/compsci/CS1labs/Mippet.ppt with pictures. Example coursework which probably could be ported to Python/Turtleart (or more likely Etoys with its collision detection) at http://www.rowan.edu/mars/compsci/cs1labs/SIGCSE03.htm .

Re: [Sugar-devel] Interesting USB-pluggable robots, controller boards, and sensors
Kevin Thats good! Please document somewhere all the steps you took. We should bring all the robotics/sensor stuff together somewhere. (I saw there was free Linux software for the Picaxe too). Deployments can then choose what I/O hardware suits them. Tony I have a Ti Launchpad (a $4.30 USD + shipping?) micro-controller board that uses the msp430 line.

In the process I've run into some design decisions. In particular, with activities with few actions, updating the toolbar concealed the actions behind a ToolbarButton (see Get Books, for example). This did not seem right, so I took the liberty of moving main actions to the main toolbar. From http://wiki.sugarlabs.org/go/Features/New_Toolbar_Design#Benefit_to_Sugar - /Make process of switching between toolbars more clear, use tool buttons that are showing all the time (in main toolbar), i.e., having Close/Help buttons visible all the time could be very useful./ seems to support my decision.

Also on the dev workflow. Thanks, I'm happy to finally contribute code again. Sebastian Hi Sebastian, thanks for your work! I remember that we had defined some guidelines when using the new toolbars. So if I remember correctly (Gary feel free to correct me) we agreed that for simple activities the options can be moved to the main toolbar. Some things should be considered here (can be seen in the screenshot attached and the code is in [1]): - left should be the activity icon with the name in the palette - then the other options (title, sharing, keep) left aligned - the sharing button is made insensitive (but shown) if sharing is not implemented (self.max_participants = 1) I think we have not writing those guidelines down yet ([2] does not say anything about it and as well I could not find that info in any design page). Gary, what would be the best place to keep this info? Yes, the new toolbar design is an addition needed for the Sugar HIG update/rework. Plan is to take a static snapshot (a fixed readonly document) of the HIG as it stands on the wiki, and then update/rework the wiki HIG. Thanks for the reminder about the special case for minimal/simple activities (I'll need to go back and dig out the old discussions). --Gary AFAIR, I did code the help activity based on the discussions back then. This is the closest documentation I have :) Its screenshot day. In this case I also moved the Browse Toolbar items to the main bar (like I observed in Browse).

[Sugar-devel] Twisted Sugar Advice
I'm a retired computer science teacher with a limited amount of python experience. About a month and a half ago I decided to volunteer about 8-12 hours a week of time to Sugar Labs. Unfortunately Sugar Labs is using a software stack that I am not very familiar with. I managed to learn git enough to get a project up and down. Being familiar with Ubuntu I set up an Ubuntu 10.4 LTS virtual machine running a Sugar emulator and an Eclipse/Pydev development environment. I got the FLOSS manual on Sugar Activities and learned that I needed to use the GTK framework. I wrote one or 2 simple gtk programs but did not port them over to Sugar.. Also at this time I agreed to work with someone from Columbus Girls School. Unfortunately her mother became ill and she had to leave for California. So I decided to learn Python + GTK developing a practice program. The program was a simple server that would ask drill math questions. Clients, either on the same machine or on a nearby machine would answer the math questions. This was not to be fully developed with error checking and all defs fully implemented but simply a proof of concept work to keep me on track in improving my Python skills. Twisted looked like a good match with GTK. So I wrote 1 or 2 simple Twisted client/server programs. Unfortunately learning and making 2 event driven frameworks Twisted + GTK play together nicely became very frustrating. It reminds me of the time I had to make Ubuntu and Windows play together nicely- I did it but it took me time and effort. So I have a following set of questions. 1. Will Twisted play nicely with Sugar (i.e. should I keep going on with this model- writing a twisted (GTK?) question server with a Twisted + GTK answer client. My thinking on this model is from my years of teaching is that students like to compete with each other and this model may add some collaborative learning when tweaked. Is this something worth continuing? I believe I can make Twisted + GTK work with difficulty but I'm not sure that about Twisted in Sugar. There are two many unknowns for me. 2. If anyone thinks Twisted + Sugar(GTK) is worth pursuing, does anyone know of any good tutorials or information on this. 3. If this is not worth pursuing what would be a good way I could devote about 8-12 hours to Sugar Labs Activities cheers, Mike -- Mike Rehner Groveport(Columbus) OH 43125 614 497 9774 www.e-wrench.com myitclass.dyndns.org ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

Even modern DSLR cameras come with the IR-cut filter right in front of the sensor, but cranking up the ISO and blocking the visible spectrum can still result in some nice IR images (with whatever little IR that passes through).

The correct link is currently: http://wiki.sugarlabs.org/go/Sugar_Creation_Kit#f15_gnome3_with_sugar_0.92.0 Also, in this section you refer to, I can't tell if this is a test report, an installation procedure, or something else. It seems to be a farm of links with a few commands thrown in. I'm puzzled as to why the section is inside a section ON-LINE VERSION, and why the section is in the page Sugar Creation Kit.
