Many Tamagotchis Were Harmed in the Making of this Presentation Posted: 31 Dec 2012 02:00 AM PST Fascinating talk about hardware hacking Tamagotchis. Thanks for the tip from Malcolm Tredinnick, who noted: "A nice combination of low-and high-level hardware and software reverse-engineering. Many techniques and tools that will be familiar to regular Adafruit readers in isolation and here they're all pulled together into a fun story." I totally agree. From the YouTube video description from the conference: Many Tamagotchis Were Harmed in the Making of this Presentation You might remember Tamagotchi virtual pets from the 1990′s. These toys are still around and just as demanding as ever! This talk covers my attempts to hack the latest Tamagotchis. Starting with the IR interface, and moving down into the hardware, this presentation will discuss techniques for reverse engineering a device with limited inputs, computing power and debugging capabilities. Recent Tamagotchis are more than just pets. They can talk to their friends over IR, support games on external ROMs and store generations worth of information about their ancestors. This talk goes through the different ways Tamagotchis can be tampered with through these channels, including making Tamagotchis rich and happy over IR, altering their states in persistent memory and writing custom games. It also goes through attempts to dump the Tamagotchi's code from ROM.

Re: How fast does PWM actually need to pulse.... Posted: 31 Dec 2012 01:37 AM PST Also, starting a motor takes a higher duty cycle than keeping it running. Start speed of a motor or valve has always been higher than the minimal running speed of that motor or the smallest opening of a valve for the uses i have seen yet. This however ...

Re: Problema pin PWM Posted: 31 Dec 2012 01:33 AM PST Ho provato ed effettivamente gli encoder funzionano anche senza pin PWM. Grazie delle info!!!. I motori non so a che velocità girano ma hanno dei motoriduttori 87:1, e gli encoder variano di 1000 stati per 3 giri di ruota. http://www.pololu.com/catalog...

Push Button With OSH Logo Posted: 30 Dec 2012 09:30 PM PST Push Button With OSH Logo.

Re: Looking for an LED driver Posted: 31 Dec 2012 01:18 AM PST Google for "joule thief"... Ok, it's not current regulated, but with only one battery you need some sort of booster before you can do anything much.

Ramping w/ servos using the Uno R3 Posted: 31 Dec 2012 01:17 AM PST Hi, I have two servos controlling a little bot. I am using this to learn how to use the Arduino. I also did many general tutorials to get familiar. Anyways, I want my bot to move forward, turn one way, turn the other way, and reverse back all with ramp...

Re: Newbie needs assistance Posted: 31 Dec 2012 01:16 AM PST Nick, I know i've asked alot already, but could you possibly go into more detail about making the impulse mode statements and warp mode statements loop round indefinitely? I've been googling around but havent come across anything helpful and not confus...

Re: Too many "if" statements? Posted: 31 Dec 2012 01:15 AM PST Like I said...  it's long.  Still only about 18,000 bytes compiled though...  25,000 if I un-comment some more "if" statements.

Re: Isolating servos from temp sensors/arduino Posted: 31 Dec 2012 01:14 AM PST Yes, the grounds need to be connected together. However, if the sensor and the power supply or servo connection share the same pin connection and wire, then the current flowing in that connection and wire will induce a voltage across it, due to the res...

Re: demande conseil d'achat débutant Posted: 31 Dec 2012 01:14 AM PST oui pour limiter le courant qui traverse la LED. Il faut mettre une résistance fixe.

Spanish Holiday Music Performed On #makeymakey #makeymakeymonday Posted: 31 Dec 2012 01:00 AM PST Via @ericrosenbizzle. xmas music in spain played on fish, champagne, crab, shrimp, grapes, gifts, etc. with #MaKeyMaKey And from the YouTube video description: Cada año vuelven los tópicos navideños: los típicos adornos, el gordo de la lotería, el de Navidad… La típica familia feliz, los petardos, los langostinos, el turrón, las uvas, el cava… Y el concierto de año nuevo, tan típico. ¿Y si a todo esto le metiéramos un poco de tecnología y creatividad digital? ¿Y si lo típico fuera reinventar los tópicos cada año? Suena bien, ¿verdad? [ED NOTE: And here's quick Google Translate version, obviously very rough...rather than revise the resulting prose it I'll leave it that way: better than my nearly nonexistent Spanish.] Every year Christmas become topics: the typical ornaments, the lottery jackpot, the Christmas … The typical happy family, firecrackers, shrimp, nougat, grapes, champagne … And New Year's concert, so typical. What if all this we Shove a bit of creativity and digital technology? What if he was reinventing typical topics each year? Sounds good, right? Feliz 2013 Read more.

The Hacker School Experience Posted: 31 Dec 2012 12:00 AM PST The Hacker School Experience @ GeekMom | Wired.com. When Hacker School made a big splash in the news last spring, it was due to their new grants for women. Sponsored by Etsy, GitHub and Palantir, the grants were aimed to help make Hacker School more affordable and inviting for women interested in attending the three-month student-led educational program. Hacker School is actually free for the accepted few, but living in their New York locale for three months can get pretty pricey.
