since size is an issue, would this one work? http://www.newegg.com/Product/Product.aspx?Item=9SIA1EF0PD5970 I have one of those powering a model A with a PiGlow - I'm guessing it'll last a couple of hours or more at 1A. I bought mine because of what this guy was using them for... http://www.raspber...
I presume you only have one WiFi dongle, so that means you can only connect to one of the networks at once. You want a simple way to switch between these, without having to edit the wpa supplicant config file each time. Correct? There is a GUI based wpa supplicant tool when you run startx that makes...
I know this post is about 2 weeks old, but have you considered water jet cutting? I have has large metal sheets cut and shapes then cut into these for £30 before. I got my acrylic / perspex laser cut at phonoptix a month ago and they did a great job at a great price. But if you can water jet cuttin...
You need to make it exciting for young learners, it's too geeky and too little on easy beginner applications. Fair point - there are other better sources out there when you're starting out. I second reading the MagPi - it's free online, offers a wide range of articles for beginners up to experts co...
"Chromium" is chrome from Linux including the Raspberry Pi so from a commmand line type sudo apt-get install chromium Once that's done, you'll see chromium with a blue Chrome icon - go to youtube as normal, and play away. Web browsing is a lot slower than you're probably used to (I'm guessing due to...
I've received these, though I ordered off eBay and not DealExtreme. Pity they don't work as a Micro SD --> SD card adapter...<snip>. Would these do the job you want: http://shop.pimoroni.com/products/adafruit-low-profile-microsd-card-adapter-for-raspberry-pi As well as adafuit and pimoroni, I've se...
I've got a couple of these: http://www.szedup.com/show.aspx?id=1762 for use as long distance WAP WiFi for my quadcopter. You may be able to get them from ebay, but in the end I got them from this guy in Hong Kong as he offered fast delivery via DHL: http://www.hongkongeek.com/en/network-accessories/...
Sorry can't help you on the build problem; both because we can't see install.sh, and also because my bash is useless, but... If you're building this driver to run a WAP with the RealTek WiFi dongle, then you can pick up what you need here http://www.daveconroy.com/turn-your-raspberry-pi-into-a-wifi-...
It's a common topic with more questions than answers. Worth searching the forum to "battery" - you'll get lots of hits - and there are good circuits / advice / code out there to make the search worthwhile.
I think you've done a brilliant job - I particularly like the fact that you've got all the "expensive parts" like the laser diodes and motors from the DVD writers - it makes this project really low prices, but high value - well done! Did you make the laser diode housings that you push the doides into?
It can be made to work with the Raspberry Pi, but not directly; it will require an analogue to digital converter and some other bits and bobs - the sensor 's resistance depends on the density of inflammable gas in the air. From reading the data sheet (which I recommend you do http://www.parallax.com...
More importantly, the chip is a surface mount component with much narrow spacing between it's contacts than a breadboard's (0.65mm rather than 2.54mm), so can't be connected to a breadboard without a breakout board like the one from ModMyPi.
Yup, the disk image you've installed on the model B SD card will work fine on the model A - I've moved a couple of my projects from B's to A's just by moving the SD card across. Only problem will be if you need 2 USB sockets or the ethernet socket.
Sorry, I should have been clearer - it's the current drawn by the motor that critical - that will be the current drawn from the battery through the PicoBorg. Given the PicoBorg's limit of 1A, your motor needs to draw < 1A at 7.2V. I suggest you connect your motor to the battery via a multimeter to m...
It's unlikely the PicoBorg is going to affect the Pi looking at it's circuit diagram https://www.modmypi.com/blog/picoborg-basic-motor-set-up-guide Your battery is just powering your motors - how much current drawn from the battery depends on the motors you use. Do you have any information about the...
Why not power it through the normal micro USB power connector? Is there a good reason? Doing it that way would open up the single type A USB port for your dongle.
Does your nephew want to build a Raspberry Pi camera with a display? That's what your list of components seems to suggest. If so, this list looks good, but certainly adding the display isn't a beginners project unless you can find one with HDMI or AV input. If the camera isn't a specific project he ...
Problem solved but not by assigning other keyboard signals; The underlying problem, which I tried to distill as much as possible to make the post as small as possible, is that my code uses subprocess.Popen to start up raspivid. Hitting Ctrl-C for my code is caught in a signal handler and does "stuff...
