  • These are eBay comparable prices for 18650s but I'm assuming you have a good supplier because none of the cells I've tested from eBay are even 1500mah (though they're all labeled >2000). So by "these cells have been tested" do you mean you've tested these specific cells or just 18650s in general? Sorry if it seems like I'm being over cautious.

  • Solder between the lines.

  • It may just be by chance but I've only seen and used mini A to OTG A and not micro.

  • I think it would be worth noting the difference between OTG and regular USB. Physically OTG has pin 4 of the b side grounded (in mini and micro) while regular has it terminate.

    From my experience, there are things that require one over another. I know the connection between my gumstix and a usb hub is picky so it's probably safe to assume the beagleboard and similar boards may have that as well.

  • I just purchased a Leonardo and I'm having issues with it on 7. I plug it in and for about ten seconds it recognizes the device as an Arduino Leonardo under "Other divices". Then it switches to an unknown device under usb controllers. I rush to check the hardware ids before it changes and get USB\VID_2341&PID_0036&REV_0001 USB\VID_2341&PID_0036 When I try updating the drivers windows tells me it already has the best drivers for it. I've tried the 1.0 and 1.01 ide's drivers and none work. Could it be a bootloader issue?

  • Haha, I gave up on the YouTube cc after trying to watch a video of a guy with a heavy accent demo his gumstix.

    I really do like the demo though. It has a very personal feel to it. You seemed to really enjoy the project which makes it a lot more interesting to the viewers. I know I'm not the only one who saw it and thought "I wonder how big of a speaker I could make like that." Instructables and similar sites with mostly pictures are great but they lack the enthusiasm.

  • "Don't do that at home." @5:14. Just the way you said it made me laugh. Great demo.

  • "a world where every child has access to cheap programmable computers"

    Anyone else thinking Megaman BN?

  • Exactly as you said, my issue with such programs is completeness. I do not dislike the GUIs, the ones available just did not have specifically what I needed. For most people it has plenty to get started and if enough time is put in, some pretty amazing things can be made.

  • For a few years I helped teach programing, physics, and algebra using scratch and other similar programs. They were having difficulty with placement of blocks and the limitations of certain blocks. We switched to a basic text IDE and they got a lot more work done.

    While using Scratch, I had to find a lot of workarounds to a lot of things. It's been a while but I think one example was "keyPressed." If I remember correctly, this is the only keyboard input in Scratch whereas Processing has quite a bit more options. It is possible to do most things with it, and the logic solving is good for the students, but it took time away from some other important topics.

    I had the same issue with EasyC and Mindstorms. The "text" programming is extremely restricting in EasyC in that it only allows text input into premade "mad libs" like lines; and the students learned a lot faster when we switched to NXC from Mindstorms for the NXT brick because variables are a lot easier to work with in line code.

    Ease of use in a GUI gives up a lot of the freedom that I wanted to show the kids.

    I also found that the kids actually comment by themselves when using line code even though it wasn't a requirement.

No public wish lists :(
