  2. Dishwasher

    hi out there First - I am new to PI so I dont hope I have missed something.... My daughters dishwasher got a sick controller suddenly and I try to replace it with a Pi Zero I need to control 5 220v relais (heater - pump - "soap" - outlet-pump - salt) - and about 8 LED and 3 buttons (on/off - program selector and the emergency pump - not ure how this is connected yet) Anyone with a similar project I could look at? Someone with some wiring suggestions for LED and relais Driver? And some with a overview of a dishwasher "program" ? br /ti
  3. Hello! I'd like to show you a little project that uses a raspberry pi to control/monitor my freshwater aquarium. Named after PiAC - (Raspberry) Pi Aquarium Controller - the github repo lives at https://github.com/dentex/piac with all the info available. I'm going to update the repo with the new features I finished, as soon as I have some time for this... So I'll try to update this thread also (although it seems that Tapatalk doesn't like this very much - I had to be on the PC) I'd appreciate any feedback, thoughts, critics etc Regards, Samuele
  4. Hi, I'm hoping to build a 4 channel motion activated sound effect system. I'm thinking of using IR motion detector to trigger start of sound effect. The system would send same sound to 4 channels but at different volumes. To compilcate things I'd like wireless speakers, either bluetooth or wi-fi. I've done a lot of googling and It lookslike it might be possible with Rasberry PI, not sure about wireless bit though. Any suggestions where to start would be greatly appreciated. Thanks Colin
  5. Internet not working now.

    Help. Background: My PI is STATIC IP. It works/worked on my LAN. I took it somewhere to get a bit of help getting it set up as a NAS device. Of course their network was DYNAMIC - or at lest not compatible with the settings I had. I didn't fret on what was done as the person was helping me and we needed network access. We got the initial problem fixed and all was good. I got home and now I can't browse or PING any URL. Eg: google.com But if I PING 8.8.8.8 it works. /etc/resolve.config has the correct nameserver addresses. They work by virtue that the PC is working ok with those as the name servers. Thing is: It used to work, now it won't. I edited the nameserver enteries to 8.8.8.8 and it worked...... Go figure. Anyone? P.S. The /etc/interface/networks is as it was. It is set for STATIC IP.
  6. "DELUGE" setup help with new PI

    Hi again folks. My second PI is the newer one with the 4 USB Ports. This is because I am wanting to set it up to download torrents and the two extra ports would give more space to save files. I don't know the vocabulary so I am inundated when people speel off the commands, which I don't understand. How do I mount the USB sticks? Also to allow me to run it headless, I have installed tightvnc but can't remember how to make it auto start when it boots. Would someone please help me with this too? On a bit of an off topic: I have a C++ book for dummies, but that doesn't really help me with the PI. (more for Arduino) Which "language" does the PI's OS use? UBUNTU? So I can learn how to add/edit auto start programs, etc. Help appreciated.
  7. We are doing a project for our intro to programming class. We are making a temperature sensor that will send our data to sen.se. When we run our program on our raspberry pi this comes up: Traceback (most recent call last) : File "/home/pi/Desktop/1.py", line 14, in <module> device_folder = glob.glob(base_dir + '28*')[0] IndexError: list index out of range What does this mean? and how can we fix it? Thank you temperature code.txt

  11. On my web site at raspberrywebserver.com, I've written tutorials about web programming and programming with databases in Python. I want to build on the ideas in these tutorials to do something a little more complicated. To that end, I built a Raspberry Pi temperature logging system. It consists of two scripts. One is triggered by cron which reads the temperature from a DS18B20 sensor, and logs it in an SQLite database. The other script is a web UI that displays records from the database using Google charts. You can see a screen shot here:
  12. For those of you who contributed to the Ghost Kickstarter Project Ghost will be released to you this coming Friday and publicly to everyone in the next month or two. If you need an environment to test Ghost or want to run your blog off a Raspberry Pi this article will show you how to get node.js, the web server that Ghost runs on, npm the package manager for node, and Ghost, the Kickstarter funded blogging platform, running on a Raspberry Pi with the Raspbian operating system. Initial Setup With a clean install of Raspbian run the following commands: sudo apt-get update sudo apt-get upgrade sudo apt-get install nodejs sudo apt-get install npm Download and Install Ghost: Go to the Ghost download page and download the latest nightly build. unzip -d ghost Ghost-Nightly-0.2.2-36.zip You can place the ghost directory anywhere you like....I have mine in /home/username/sites/ghost Execute the following commands: cd ghost/ sudo npm install Now you just need to edit the config.js file and replace the listening address and port to your Raspberry Pi’s IP address. For example replace "host: '127.0.0.1'" with "host: '192.168.0.10'" and "port: '2368'" to "port: '80'". And finally run: npm start to start Ghost process.

  13. run java faster on raspberry pi

    I have developed a java application to be run on raspberry pi. In my application, if a user clicks on a particular button, it will switch to a different screen. This is working pretty well on my pc, but on raspberry pi it is taking lot of time to switch to the new screen. To check which part of the code is utilizing lot of time, I have measured the time taken by different parts of the code. Seems like, its due to loading a new fxml file and display the screen using stage.setScene(scene). So, I think this is causing the problem. Is there anyway I can reduce time taken to load fxml file and to display the screen?. Kindly help me with this
  14. Hello from TX

    I just purchased my pi a week ago. I also purchased the atrix lapdock for motorola g3 phone. Following the adafruit youtube tutorial I am going to make a laptop with lapdock and the pi. In a couple of months I plan to buy another pi. With it I want to run an ASIC miner used to mine BTC. I have seen some people post on reddit showing picture of their raspberry pis running BFL jalepenos. I'm excited about both of these endeavors.

  18. Hello all! I thought I would post a project I have been working on. I call it the FruitStand. The name is largely Raspberry Pi influenced, however its just as much for smaller boards like the Arduino. Basically it gives you a nice sturdy place to pop your boards in an out of. I just launched it on Kickstarter.com, but I really would like some feedback for you all. I have attached some pictures of it on this post. Thanks, Ben
  19. Hey there, I am new user here and I was wondering if anyone of you can help me. I have a project where i am suppose to make a camera which would record only once it detects motion. To detect motion I was thinking of using a PIR sensor but i am not sure how to make the camera record. Can I use the Raspberry Pi board to connect the camera and record once the PIR sensor detect motion. Is it possible. I have never used Raspberry Pi so I am not sure if this would be a good project to use it. Thanks in advance, Madman

  21. The engineer behind iconic British computer the ZX Spectrum has given his backing to the Raspberry Pi project, although he still feels that simplicity is the key to engaging young programmers. In a fascinating interview with the BBC, Richard Altwasser expresses his delight over Raspberry Pi – a tiny and ultra cheap computer that has been designed to capture the hearts and minds of a new generation of kids. "I'm an engineer so I'm delighted at the thought that people are going to be encouraged through the availability of the Raspberry Pi to learn to do programming," said Altwasser. Appealing The Sinclair ZX Spectrum was a computer that played a large part in a huge explosion in British programming talent in the 1980s, and remains one of the most fondly remembered early PCs, and this week celebrates its 30th anniversary. Part of the appeal of the Spectrum was how easy it was to write a program, and Altwasser believes that the increased power of Raspberry Pi compared to the Spectrum does not necessarily give it an advantage. "If I look at the capability of that machine - the graphics pixel rate is 140 times greater, the processor speed is 200 times greater, there's thousands of times more memory," added Altwasser. "So you would think the speed and power of that device compared with the ZX Spectrum gives it every possible advantage. "But my impression is that the attention span of young people over the last 30 years has probably not lengthened. "What is important is not the technical speed of the device but the speed with which a user can get their computer out of a box and type in their first programme."

  22. The Raspberry Pi Foundation has provided some pricing updates for the cheap educational computer, making it clear to buyers in various countries what they will have to pay. A blog post on Tuesday provided updates from the two worldwide distributors of the Raspberry Pi, RS Components and Element 14/Premier Farnell. RS Components said it had decided to set a single global price and delivery charge, namely £21.60 and £4.95 respectively. The supplier also said that UK VAT would be constant at £5.31 per device. However, the foundation's Liz Upton added that those in the rest of the EU may have VAT calculated differently, and other local sales and import taxes may be applicable outside the EU instead of VAT. Meanwhile, Element 14/Premier Farnell provided a grid showing how much would be payable in each country, in local currency. According to the distributor, customers who had already registered their intent to buy and were quoted different prices at the time would only pay the cheaper of the two prices.

  25. The Raspberry Pi Foundation and electronics design portal element14 are offering techies a chance to win a free Raspberry Pi computer. The "Raspberry RoadTest Challenge" asks contestants to answer the question, "What innovation will you create using the amazing Raspberry Pi computer?" Element14, a division of technology distributor Premier Farnell, announced a deal with the Raspberry Pi Foundation in late February to distribute $35 Model B Raspberry Pi computers with two USB slots, 256MB of RAM, an HDMI slot, an SD memory card slot, and an Ethernet port. A $25 version with just one USB port called the Model A will be made available later this year. While the bare-bones, credit-card sized Raspberry Pi computer has been attracting a lot of attention since the foundation started accepting pre-orders late last month, the project hit a snag a few days ago when it was discovered that a production run of Raspberry Pis built the computers with the wrong jacks. The Raspberry Pi Foundation said in a Thursday blog post that "specifically, where we'd specified jacks with integrated magnetic in the CBOM and schematics, the factory soldered in non-magnetic jacks. No magnetic means no network connections." The organization said it had known about the issue for four days, but hadn't said anything because it was conducting further tests to make sure nothing else was wrong. For existing models, Raspberry Pi claimed it's a "very minor problem to fix." It must desolder the wrong jack and attach the correct one. The production plant is almost done fixing the first round of computers, it said. However, there are some foreseeable issues in securing the proper jacks for the next round of Raspberry Pis, because all of the Ethernet ports Raspberry Pi thought it had turned out to be the wrong part. Though it's already searching for the jacks, the organization said there could be future delays. Whether that could also mean delays in the delivery of Raspberry Pis to the RoadTest Challenge winners remains to seen, but those wishing to enter the contest had better not delay getting their entry forms in. The winners will be announced March 14 (also known as "Pi Day," fittingly) and details for entering the contest can be found on element14's dedicated contest page. Source: PCMag
