If you're dealing with RF, you'll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino and a break...

hello,
I asked myself if it is possible to install an Arduino bootloader
a AT90USB646?
Where can I to. Getting hex files I need to upload the uC
and what do I need to install extra to then be able to use the Arduino IDE? bootloader
sory for my bad english

This will do it: https://github.com/unrepentantgeek/brainwave-arduino

I plan to revise it quite a bit though to line up with Teensyduino pin mappings.

#Help required.

I'm currently trying to have Arduino read my BatMouse II remote control. The remote is originally used for an InFocus projector. It's a great remote, solid built, with a trackball and mouse buttons. Perfect for TV browsing etc. It would be great to use Arduino to bridge the remote to my media center. However i cannot read anything sensible from it.

I've measured the #IR modulation freq. which is 38KHz and I do get HEX codes out of Arduino, on every press on the remote. But the HEX codes are inconsistent between presses on the same button.

Every time I press a remote button I get HEX codes that are different from before, and sometimes the HEX code sequence repeats on about every 3'rd press of a remote button.

Its also like there's an encryption in the IR codes protocol. When i monitor the IR signals on the remote, its like the timing between some of the bits changes on every other remote press.

I found somewhere on the net, that InFocus follows the NEC standard, but when I run my sketch using the NECIR specific library, nothing is shown by Arduino.

The IRremote library returns UNKNOWN type and garbled codes.

Anyone have any inputs to this...

Chris Young's IR library in action on my little robot: http://inventorartist.com/rolly-bot/ #simple
All my friends are making robots and I feel left out so here's my installment. It's also my entry for the Ottawa Arduino Challenge. Most people are using a pair of geared motors drives and castors. You vary the drive to each side for steering. It's elegant and allows a tight turn radius. I will

Hello,
I want to create open hardware and open source calculator and I'd like to ask you for few advices.

1. At first I thought of Arduino, but it has low performance and not enaught RAM. I think I'm going to use TI C28341. Do you think this is good choice?
2. Display - Any recommendations? Or should I just find one?
3. Keyboard - Where to buy one? I've never seen anyone selling custom calculator keyboards.

Software written in C. First version of calculator software will be available in few days on Github.
Please give me a feedback on what you think about this project too.

Yeah, TI has this market cornered. Using one of their chips just makes it even more apparent.
Why not take apart one of theirs? Open Source the wheel.
Just make sure your intellectual property is unique.

Personally, I'd try their MSP430 line because it's low power, then an LCD controller, and keypad controller to keep the code small.

The laser cutters you find at hacker/makerspaces are awesome...but if you want a desktop version for smaller projects that involve cutting paper or engraving on wood or plastic, check out the #Arduino -based Laser Cube ($199 on Kickstarter) - http://goo.gl/YdhhK2

A small arduino micro connected to the internet for turning on or off a led with an html5 web app from a android phone.

In future I'll post also the cleaned code, till then here is the current working version of it:
https://drive.google.com/folderview?id=0B1FW7luWJYleR2E1a1M2dXFTaGM&usp=sharing

Connections are done like this:
VCC -3V3
RESET-RST
ENC-INT 2
GND-GND
SCK-15
MISO-14
MOSI-16
CS-10

Here is my second 433MHz RF tutorial.
I use a 433MHz receiver to capture a Mercator Fan/Light RF remote control signal. I guess you can see where I am going with this.

No Libraries or sound cards required - just an Arduino and a 433MHz RF receiver.

Fully documented here:
