new product categories capable, quite literally, of changing the world.”Advanced functionality, power efficiency and integrationThe Kinetis KL03 MCU combines the power efficiency of the Kinetis L series based on ARM® Cortex®-M0+ cores with enhanced low-power functionalities including register files, SRTC, low power UART, and additional low power wake up pins.Additionally, the new product offers greater ease of use over the previous generation. An added ROM-based boot loader allows factory programming and on-line system firmware upgrades without adding circuitry to the board, reducing programming-related costs for customers. An internal, highly accurate voltage reference (Vref) delivers improved analog performance by supplying an embedded 1.2 volt reference for the ADC, enabling several use cases for applications requiring high ADC accuracy.The Kinetis KL03 MCU integrates:48 MHz ARM Cortex-M0+ core, 1.71-3.6V operationBit manipulation engine for faster, more code-efficient handling of peripheral registers32 KB flash memory, 2 KB RAM8K ROM with on-chip boot loaderHigh-speed 12-bit ADCInternal voltage reference for high ADC accuracyHigh-speed analog comparatorLow power wake upLow-power UART, SPI, I2C (high speed)Secure real time clockPowerful timers for a broad range of applications including motor control-40 °C to +85 °C operation

This chip is a game changer...

If this is true, I think I'd physically be sick...

Sure this new arm chip has some amazing potential to change the world and I can easily see the importance this new arm chip will eventually play...

But.... I feel sick thinking about the fact that he's the possible reason why... digital warfare killing people for a patent, it adds up! Robert Noyce would be turning in his grave!

I'd put a 300 ohm resistor on the base (while you swap them around)

Sounds like you could do with a step up and step down switch mode regulator...


Plenty on ebay.

Old school way...



Or feed the amplified signal into a0 of arduino, and then switch it on (lot easier too) but I like the 4017 smiley
442  Using Arduino / General Electronics / More current parraraling up... on: March 25, 2014, 02:16:52 am
Using 2 or 3 7805's or 2 or 3 transistors, due to voltage missmatch and one burning out due to excessive current from a higher voltage...

So how do inverters get around this problem?

Look up Joule Thief some time.

There's a MAKE Article and Youtube about making a bracelet that uses sunlight on photodiodes to charge 3 caps that a Joule Thief made mostly from a small choke (you don't even have to wind coils) to light a led you can see in daylight.
The full article: http://makezine.com/projects/Solar-Joule-Bracelet/
The YT: https://www.youtube.com/watch?v=ghB2irHIN8I



A joule thief will only be if use if you're powering less sensitive electronics with it, or the ripple will mess up the operation of most ic's.
444  Using Arduino / Project Guidance / Re: Power supply help? on: March 21, 2014, 09:51:40 pm
Just buy a 7805  and an lm317 or a 3.3v ldo (surface mount)

445  Using Arduino / Project Guidance / Re: lighting a tunnel on: March 21, 2014, 09:41:53 pm
Yes, you'll need to use high powered leds, 10watts at least each, and mosfets/power transistors to drive them...

As for detection,  maybe an infrared motion sensor .

I don't get the pascal joke (4)

Even if you get them all, they're not that funny lol

That's a true logic level mosfet.
448  Using Arduino / Motors, Mechanics, and Power / Re: Logic-Level Power FETs you'd like to see/use?? on: March 21, 2014, 11:06:36 am
Neither are logic level mosfets.

So I guess for beginners/kits neither are ideal unless you're happy not being able to saturate the transistor.
449  Using Arduino / General Electronics / Re: shift register resiliance? on: March 21, 2014, 05:16:05 am
Shiftregisters use flipflops,  transistors, there's nothing to wear out ..

The capacitor is the first to fail, refresh writes in memory, the voltage gets unstable and leads to a bad read, but transistors hardly fail unless exposed to too much current or voltage.

Wow, that is surprising...... I figured all sip style ic's were just resistor bridges.
