31  Using Arduino / Microcontrollers / Re: Intel Galileo has integrated linux OS on: July 26, 2014, 01:59:42 pm
Anyone knows where I can download source for that embedded kernel with bootloader?

It's here: http://bit.ly/1lGTeHQ

lol, nice try bro,
If it was such simple I wouldn't ask for help

Huh?

The third result is "IntelĀ® Galileo software package" and it leads here: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23171

Took me all of 15 seconds to find it.

33  Using Arduino / Microcontrollers / Re: Drive Servo with Attiny84 on: July 26, 2014, 05:49:42 am
Hello everyone

Is it possible to use an Attiny84 to drive a servo? I understood that when I bought the Attiny84 it has 16-bit timers, and so should be able to use the Servo.h library, in the same way as an Arduino Uno?

Is that correct thinking?

Yes. It has a 16-bit timer, like the Uno.

If it is possible is there anything I need to know about which pins to use?

Definitely possible.

PS: 6V to power the Tiny85?

There's a lot of very suspect things on that page.

This person has connected CE from the nrf to ground so that it is always in receive mode - I dont know if this works or not

It definitely won't work if you connect it to GND. That would lock it in standby-I mode.

It might work if you connect it HIGH and you only ever need receive mode. I never tried it ... (maybe I should)


36  Using Arduino / General Electronics / Re: Where to find pluggable 2.54mm terminal blocks? on: July 26, 2014, 05:12:02 am
My idea is to connect these directly onto the arduino and components for a more rigid build without having to solder. Does anyone have any experience of this product and know where to order it in Europe I'd be very happy! Thanks!

Something like this?

Or you could just remove the header strips from an Arduino and put 2.5mm screw terminals instead. Or get a Pro mini and put some on that...

I am surprised that you can find 2.54mm pitch blocks with pins as that would mean that the screw terminals are very close together.  Are you sure that the pins are spaced 2.54mm apart and not a multiple of that ?  Can you please give a link to an example product ?

You mean these?

I have been looking to do this for sometime, and with using the nrf2401 with an ATTin85 there is only one pin left to use

How did you connect a nrf2401 with only 4 pins?
39  Using Arduino / General Electronics / Re: Component to connect parts in parallel on: July 26, 2014, 03:04:15 am
you can get one of those pin strips and cover one side with tin foil... or just cover a side with solder...etc

Yes. Tin foil - well known for its robustness and current carrying capability,

40  Using Arduino / General Electronics / Re: Setting up 'switch' on: July 25, 2014, 10:20:58 am
So is it like an input and an output?

Only if you define "output" as a very weak 5V signal and no way to turn it LOW without losing the "input".

I would like to send a HIGH signal down a pin to a switch and totally shut off power to my entire project.

It might have to be a LOW signal... smiley-sad

Use a MOSFET with a pull down resistor on the gate. The Arduino can put out a HIGH signal to keep itself alive then turn it LOW when it's finished.

To power it on you'll need to apply a HIGH signal to the gate until the Arduino can take over. You could add a button to the device which pulls the gate HIGH while you hold it down. This saves you from having to toggle the power switch.

The only problem is the default bootloader which will take a few seconds to start up (or maybe this would be a safety feature, I don't know...).

You can fix this by:
a) Using optiboot (the bootloader only waits three seconds after a reset, not after a power-on)
b) Remove the bootloader altogether (use an ISP programmer to program the board).

No.

How about bolting Beer Cans together?

Most people prefer wire but if you've got an excess of beer cans lying around then go ahead. Might as well use them.

Wasnt clear for me neither

Here's the Intel product brief:

https://communities.intel.com/docs/DOC-21836

Page 2 says "Linux Kernel".

a) Broken link.

b) The datasheet will be on the digikey page. Try reading that.
