Re: [beagleboard] I think my beaglebone is a lemon
If you're new, spend some time reading the documentation. Everything and more is in there, but it's a lot to go through. For one thing, the USB port only supplies 100ma, you will need a powered hub for your keyboard and mouse. The doc's mention that. My HDMI display has a USB hub built in. Makes connecting to the BBB a breeze. Booting off SD cards is well documented. Spend some time reading. Recover your BBB back to original as documented. Then don't make drastic changes until understand what you're changing or else you'll break it again and most likely again and again! ;-) Get several more MicroSD cards. I picked up a bunch of 8Gig cards at Micro Center for 4 bucks each. You can put a recovery flash image on one and leave it. You'll need it as you experiment and work with the BBB. You can load other images on the other cards and use them as needed without having to constantly re-write a new image to the card. -david On Thu, Feb 5, 2015 at 1:21 AM, sudoer...@gmail.com wrote: Ok I have a serious issue with my beaglebone, I can't seem to use it at all. It has an issue with booting of MicroSD cards and a problem with USB. The first issue is the main one, although technically two. A while back I managed to forget my password and flashed my beaglebone with debian. However Debian couldn't load lxde, nor could I get the command line to do anything. (Specifically it loads openbox and just does nothing. In all cases it does not supply the 150~ to ~300mA current needed to support both a keyboard and mouse, (I use a kit that needs 150mA, and used a mac keyboard that needs 200mA that has 2 usb ports,) Anyway I reflash my 2GB MicroSD and attempt to boot the thing about 12 times and no success. It will display the power on LED, but no Four boot lights are seen even after several minutes. I've tried both the Debian and Angstrom images, both don't work but Angstrom seems to annoy dd as it wont display any output when watch -n5 'sudo kill -USR1 (whatever dd's current number is)'. After each failed boot attempt debian happily continues to partially boot up. Now I've tried ssh'ing and using the link to connect to the beagle bone and nothing works, the connection isn't there so my computer will just hang. I have no clue how to find it, I tried NMAP to find it but no luck. (Albeit I am a noob.) I swear to god this thing never worked the way I wanted it to since day one...

One word perhaps about the application: it is very simple. I must monitor mains power supply in different locations and have to log power outage events on a file with time stamps. I have also to log grid switching events ... The specialized 230V AC monitoring system has no Ethernet connection but can be associated with BBB GPIO's.

Re: [beagleboard] Re: question about I/O expansion
Seriously, Google is your friend. Start with how to control a relay You will need to learn out to control a relay with a transistor and why. The same reason applies to any micro, not just BeagleBone Black. Google what a GPIO is. Then google how to use one on BBB. There will be lots of information, it's hard to describe how to choose which information to use, pick one that feels less intimidating. Look for videos on youtube by Professor Derek Molloy. Adafruit, Sparkfun have tutorials. Even tutorials that aren't BBB related can have explanations of circuit operation and all the electronics hanging off of the microcontroller pins is the same or similar. Code from other microcontrollers is useless for BBB. The logic is the same, but the code to implement that logic is different for each micro. Google using interrupts on BBB. Google using I2C, and for accessing multiple relays, google I2C expanders. (They're pretty cool to work with!) Your project is a puzzle of many pieces. Many of those pieces depend on other pieces being put together first. For a newcomer, it's a lot to learn and you just have to jump in, keep notes, keep a build journal, experiment, and expect to make mistakes, they happen.

I hear that question a LOT. No, we weren't sleeping, but sometimes it takes a minute for a plan to come together. And don't you love it when a plan comes together? Your BeagleBone Black is on the way and below are the whys and hows. Buying a BeagleBone Black back around October last year was easy---and then suddenly they were gone. Having a big launch and then slowing down to a more steady pace of production is what is normally expected. Demand was strong, but distributors were showing a small amount of stock and people were getting their boards on demand. Based on the status, distributors had requested CircuitCo (the Richardson, Texas based manufacturer of all official BeagleBoard.org boards) to provide boards at a certain pace, and production dropped from about 6,000 a week at launch to around 3,000 a week. Then came Radio Shack, filling their stores with Make's Getting Started with BeagleBone kit. Then the Christmas rush. Then the Georgia Tech massively open online course on control of mobile robots hosted on Coursera. We had a couple of small production boosts, but haven't been able to make any dent in the demand. Everyone is starting to find out what BeagleBone Black can do, using it in their classes, hobbies, prototypes---and products. When it comes to those people using a BeagleBone Black in an end product, well, the BeagleBoard.org terms and conditions clearly say we aren't responsible for the quality in those cases. Nevertheless, the quality speaks for itself and many people are choosing to simply drop them into things beyond just a few prototype units. In practice, we'll never know unless you try to return a bunch of boards at once for repairs. Our desire is that people using the boards in products work directly with a contract manufacturer or distributor to enable boards builds to be planned out in time and with terms and conditions that won't hurt BeagleBoard.org's ability to supply classrooms, hobbyists and professionals building prototypes. Still, if distributors show stock, I expect people building products to continue to chew up some of the board supply. While these people building products are certainly sucking up a lot of boards, it is clear they aren't the only source of the high demand. Some of our distribution partners, most notably Adafruit and Special Computing, put quantity limits of one board per customer on their orders to help keep supply going to individual makers. I took a look at Adafruit's website while they were showing some sock and observed board disappearing at the rate of about 2-3 PER MINUTE. One tweet from me and they were sold out again. This all leads to the obvious conclusion: we need more capacity. To accomplish this, we are taking a multiple prong approach of increasing capacity at CircuitCo as well as bringing on an additional manufacturer. These two prongs are summarized below. Prong #1 - Ramping up production at CircuitCo Ramping up production costs money. More test equipment is needed. Orders on various parts must be accelerated. Additional staff must be hired to run additional shifts. CircuitCo has been fantastic at taking the risk for us, but the margins for BeagleBone Black aren't the friendliest for them to take on these additional costs. At initial launch, it is a benefit for them to get exposed to more customers for their core business, complex circuit assembly and engineering services, but shipping more of the exact same board isn't going to give them a lot more exposure. We're really close to shifting the distribution shipped on our boards from Angstrom Distribution to Debian. Feedback from different people, especially Adafruit, tells us this will improve usability in the largest segments of our community. Angstrom Distribution is much more customizable and is very friendly to professional developers looking to tweak the most out of the system, but for many novices it introduces a barrier to learning. Debian is the basis for Ubuntu, includes ARM Cortex-A8 support in their mainline and is very familiar to a huge population

I believe the distance affects the timing and any pixel acts as a repeater/amplifier of sorts for the simplistic explanation. -david On Sun, Jun 22, 2014 at 10:48 AM, lynton.r...@computa.com.au wrote: thanks for that advise I hadn't realized those strips had pwm drivers in them already, this looks like a much easier approach. looking at these now 12mm Diffused Thin Digital RGB LED Pixels (Strand of 25) https://www.adafruit.com/product/322 Only thing is I need each LED to be about 2 meters apart, Do you think they would work if I added in an extra 2 meters of cable between each LED ? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Creating a garage-venting system
Oh yes! BBB is way more than capable of doing what you want to do. Actually a bit of overkill if this is all you want to do, but anyway . . . It clould be the first module in your ultimate home automation setup. Here's a controlable outlet: https://www.adafruit.com/products/268 You would be monitoring 3 inputs and controlling 1 output. Easy Peasy! -david On Wed, Jun 18, 2014 at 12:27 PM, alema...@launchfire.com wrote: Hi Everyone, I've been digging into home automation a bit, and wanted to create a system that'll turn a socket on/off based on temperature conditions, and buttons. I started off on smarthome.com, and the controllers required to program nested ifs are really expensive - I think this beagle board would do the trick. In short, I want to turn an outlet on in my garage when: - the temperature inside reaches = 30 deg celsius, and outside temp is at least 5 deg cooler than current temp - or, I hit a Vent button and it runs for 30 minutes Is controlling an outlet with BBB possible?

If so, the missing piece is the relay to power the outlet on and off. Ideally, there'd be an inline relay that I could use (no outlet, much like http://www.insteon.com/pdf/2475sdb.pdf). Appreciate your guidance, new world to me. If I can get the hardware squared away, I can certainly figure the rest out (am a programmer).

Re: [beagleboard] Custom Beaglbone Black from Circuitco
On Wed, May 28, 2014 at 3:28 PM, sixvolts drewko...@gmail.com wrote: I've been trying to talk to the people CircuitCo about building a run of the beaglebone black boards for a commercial project, but I can't seem to get anyone to respond to emails and the two people I have phone numbers for are always busy. My understanding was that proper etiquette was to not poach boards from the distributors if you build a device around the beaglebone and have them produced for you. I even spoke to someone at a CircuitCo booth at a conference last year (DesignWest - where the beaglebone black was launched) and they indicated this was common already for the original beagleboards/bones. I can't get anyone local interested in building them because of some of the minimum order quantities on some of the parts (like the emmc). Anyone at CircuitCo around? I have money and need around 100 boards made. Good grief! your last two lines explain everything! It's obvious you haven't a clue how PCB manufacturing works and seem determined to make the system fit your world view. Your 100 board run does not even come close to their minimum order quantity requirements! Yes, they are avoiding you! You don't meet requirements! You seem to be unable to grasp the concept that your requirement is too small for their requirements, hence now you've become a pest and a nuisance! They can't help you and don't want to be bothered by you anymore! There are many, many other board shops out there! Do your homework, Google can help, Nuts and Volts magazine/website can help. The hobby oriented board shops consider this a very complex design, which it is and many will not take it. The ones that will take it are going to charge a lot. Many will only do 4 layer boards and won't touch BBB. Then you have to worry about testing. Many won't test for you and the ones that will are going to charge a lot to setup a test plan. Do you even know how to specify what you want tested? You can't just say that you want a functional board. It doesn't work that way. This is the realities of PCB manufacturing.
