Re: Cheese cave control Posted: 30 May 2013 02:55 AM PDT Quote I need to ensure that the switching doesn't harm the fridge. That is not an easy job. The issues you have to face (that is what we like) : 1. the t_tobe and h_tobe values will jump maybe +/-3 when the adc conversion not fixed properly...

Apple Shifts Supply Chain Away From Foxconn to Pegatron Posted: 30 May 2013 02:51 AM PDT Apple Shifts Supply Chain Away From Foxconn to Pegatron @ WSJ.com. Pegatron Corp. named after the flying horse Pegasus, will be the primary assembler of a low-cost iPhone expected to be offered later this year. Foxconn's smaller rival across town became a minor producer of iPhones in 2011 and began making iPad Mini tablet computers last year. Pegatron's rise means an end to the monopoly that Foxconn Technology Group — the trade name for Hon Hai Precision Industry Co., the world's largest electronics contract manufacturer — has held over the production of Apple's mobile products. They started in 2008. Financials here. Founded in January 2008, Pegatron is a worldwide leader in electronic and computing DMS (Design and Manufacturing Service) with extensive experience in product development and vertically integrated capabilities. With equity of US$2.7 billion, Pegatron boasts a diversified product line, including motherboards, desktop PCs, notebooks, broadband, wireless systems, game consoles, networking equipment, Set-top boxes, multimedia, LCD TVs, and more. At Pegatron, we take pride in our well-diversified product portfolio, unique designs, flexible manufacturing capabilities and reliable after-sale services.

Re: Program only works correctly after re-uploading at each start-up. Why? Posted: 30 May 2013 02:32 AM PDT A wild guess is that you missed a setup function for your game, a function that setups the accelerometer accordingly. That's why you need to upload the testing sketch first, it setups the hardware. Configuration is lost at power cycles.

Re: Question about ICSP and SPI Posted: 30 May 2013 02:31 AM PDT If your last post is a question, then the SPI data lines are duplicated on the ICSP pins. On the Uno, the ICSP pins are connected to D11-D13, and on the Mega, the ICSP pins are connected to D50-D52. The hardware connection could be made from either se...

Re: Conversion Chaine de caractère vers Int Posted: 30 May 2013 02:30 AM PDT Ton tableau buf est déjà de type int, pourquoi vouloir le caster de nouveau avec (int) ? Normalement un Serial.print(buf) doit te sortir ta valeur récupérée via vw_get_message().

Program only works correctly after re-uploading at each start-up. Why? Posted: 30 May 2013 02:29 AM PDT I have two pieces of code, one for testing whether the gyro/accelerometer works correctly and the other for using the accelerometer to play a simple game. My problem is when I have uploaded my game code and want to start-up (either by powering by USB o...

Deezmaker Introduces Bukito Portable Mini Printer Kit #3dthursday Posted: 30 May 2013 02:00 AM PDT One of the new models launching at Maker Faire Bay Area this year that caught my eye was the Deezmaker Bukito — a capable, affordable, portable entry-level model that Whosawhatsis and Diego carried around the Faire, printing on batteries. While this type of stunt isn't new — I took a Printrbot JR on a test drive with a quadcopter battery at World Maker Faire in New York this past year, and there were a number of backpack Ultimakers printing around the Bay Area Faire this year (read their battery suggestions here!) — I appreciated the open-yet-rugged design. The parts count has been stripped all the way down such that the cartesian robot has only single, sturdy points of connection for all three axes, and even so the printer design can handle the jostle and bustle of being carried around (see the video above for the printer printing upside down) better than those with multiple risers and reinforcements. From 3ders.org: Deezmaker announced its Bukito lightweight, portable 3-D printer at Bay Area MakerFaire this year. The printable space is approximately 5 by 6 by 5 inches (150 cubic inches). Other critical features inherited from its larger Bukobot cousins include sturdy aluminum rails allowing for a stable platform for accurate printing. According to Diego Porqueras, Deezmaker's President, the Bukito is a small, rugged printer that anyone can take with them. "It will be ideal for classroom use and can be shared between a few teachers at a school. We built it with an easy-to-grip handle and worked really hard to get the weight down to about 6 pounds." Specifications: 150 cubic inches of freedom (5″x6″x5″ / 127 x 152 x 127 mm) Works PLA 100mm+/sec speeds Sturdy Aluminum frame (no wooden parts) Uses 1.75mm filament Adaptable to Battery Power The unassembled printer kit will retail for $649. It is available for preorder now with an expected ship date in late August. Read more. Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers! Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don't forget the countless LED projects that are possible when you are modeling your projects in 3D! The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you've made a cool project that combines 3D printing and electronics, be sure to let us know, and we'll feature it here!

Re: Switching two batteries with DPDT relay Posted: 30 May 2013 01:31 AM PDT Thanks for the suggestion! I'm having trouble working out how to wire the batteries in parallel so that they're not always bypassing the relay or without resorting to a second switch (should note that I don't know much of anything about circuits.)

Re: Quadrature Encoder Signal Generator Posted: 30 May 2013 01:31 AM PDT Ah that makes sense! And please dont be sorry! So the T2Speed is limited to the overflow value right? If so then I should be able to change the overflow limit to a lower value, so that there is fewer counts per interrupt and when T2Speed equals Overfl...

Re: Just curious Posted: 30 May 2013 01:27 AM PDT Quote It does seem wasteful of space for the compiler to store 8 single bits as 8 bytes. It is, and in the "old days" it was very common to pack single-bit flags and various other < 8-bit vars into bytes. That was when your whole application o...
