Hey everyone, does anyone have a broken ps3 console or a motherboard for one. I have a CECHL01. It has the red screen of death and I want to get a new motherboard for it. If it has the ylod that is fine. If it is a system that has the ylod I might be interested in that. I have a hdd for it. I know that most people on this site would be willing to fix their own ps3.

Looking for a few coders to help make a better 3d system based on the pi and arduino. apps available will incclude: 3d printing tool usage CNC 3d scanning and more to come I have next to NO experience in coding but have designed and tested 2 machines that I need programmers for. these will be opensource at the end and also sellable. I am hoping to make a store similiar to playstore or app store so that advanced programmers can also make a small amount for exceptional products. the idea is huge but could be beneficial to several thousand people including users of this forum in helping them with techniques and skills they have not yet mastered. the project is HUGE and the mechanical side is largely done with the exception of a few parts that are added extra. other inclusions will be safety features and high perfomance. for those that are interested in this AND have coding experience I look forward to your replies on this topic

I want to build an app :) I understand that that there are sites with drag and drop features, which i will try out to get an idea of what i'd like, and use for smaller projects (any suggestions on which to choose?) But for a larger project i would like to build my own :) I have no programming skills or knowledge :( But i want to learn! SO! What i really want to know is were to start, what type of programming do i begin with? And were i progress to for app building? i.e java, joomla, CSS ( Don't laugh, I'm clueless at this point but I want to learn over the next year or so) Finally is there certain software that would be beneficial? i.e Adobe etc. Oh and is there any sites, books, tutorials, references to aid learning? Thanks for reading, I've tried googling but its a bit confusing finding were to start, but once i know the start and end point I'll get cracking :)

A while ago I was going to start an electronic tutorial video podcast, but that took too much effort to make everything professional looking and well thought out. I want to retackle this project by having a video whenever i feel like it (at least 1 a week) answering questions that people ask or just want a video on because people generally learn better via video than reading some boring text :P Also, this podcast isn't going to be editted or anything, because all of that stuff just takes away all of the fun and just becomes boring. So, in short, I'm going to start an improvised video podcast answering people's questions to the best of my abilities. Anyone have any questions that they would like to have answered?

My son has expressed an interest in Arduino because he's in an after school group of "builders" in which a number of students are toying with Raspberry Pi. He was told that Arduino can be built using a ChromeBook - we don't own a Windows computer (only Macs). He believes that he could build using YouTube and other computer based research. Can someone tell me if Arduino is compatible with ChromeBook? With so many kits available, can you please advise one that will engage him for multiple projects and may even be used for growth but at the same time is not going to break the bank? Any advice is much appreciated!!

I've decided i want to make a R2D2 for Halloween. I'm pretty sure i can make most of it from scrape metal but i don't know where i can find something that's like the head on R2D2. I need a metal sphere that i can cut in half, any ideas?
Inspired by the Illuminato Arduino clone (can't really say clone because it's so much better!) really wants me to create my own Arduino clone. I've been thinking of making a clone for the Arduino Mega, but it'd need so feature that the original Arduino can't offer (like the boarduino is breadboard compatible, Sanguino has way more pins, Illuminato is the most beautiful PCB I've ever seen and has a lot of I/O's). So, I'm asking you guys! What features would you want in an arduino? If this "new" arduino is so much better than any other existing one I'll make kits (if the majority is through hole) for people to buy (no more than 40 dollars, probably, the 65 dollar price tag is a real turn off for the Mega) or just assembled if the majority is smd. Also instructable :P

Question by prettypradee | last reply
Some friends of mine have asked me to make them a brew temperature controller for their microbrewery. I have a rough idea about how I'm thinking of doing it, but would like to check out whether I am on the right track. What they want is something that will maintain a constant temperature inside an insulated box they are building (about 3x1x1m), which the vats will go in to brew. My idea is to use an arduino controller to switch a Solid State Relay and turn the heater on and off to maintain a set temperature. I want to try using low frequency PWM (at about 5Hz) and a proper PI control loop to get really accurate control, rather than just using a standard thermostat action. I'm thinking that given that the relay should switch on every half-cycle (100Hz), this will give me at least 20 levels of control. (Probably more because as the PWM frequency drifts against the mains frequency, the number of on cycles will jump up and down by 1 around an average value.) I decided on this method rather than using a phase angle controller because they are costly and need external components (e.g. a line filter) to work properly. As far as I can see, this switching method should give me pretty good control over the temperature, but it would be good to know if anyone can see any problems with it - I'm designing this more from theory than experience. One thing I'm not sure about is how to measure the temperature. I'm thinking of using an SPI chip rather than try to calibrate a thermistor, but these cost about 4 pounds, so I'm wondering if I could save a bit of money by using a simpler method. Another question is about safety - any advice on things I should do to ensure it's safe would be welcome. I've never done a mains powered project before, so I want to be really careful. I've written up some notes on my proposed design here.
