Solar Panel 6 inches or smaller with Max. Output

Gudday! (Yep, I'm Australian) and Ahoy! (Yup, I live on a boat too). Hoping to mine the collective hive-mind here and get some advice. The situation: I need some solar panels that are six inches (or smaller) that give the maximum output so that I can charge some batteries. My question: do any of you kind folk have any advice on what solar panels I could assess and where can I get them from?Thanks in advance for any thoughts, tips or advice that you offer.

Decode Custom RF ASK Signal with Arduino & RadioHead

I have a remote that sends out a preamble, a pause and then a long code where a 0 is encoded as 100 and 1 is encoded as 110. I used an RTL-SDR to decoded the aforementioned ASK signal. I know the code is correct because I can simulate the signal using an Arduino and FS1000A. I simply connected the FS1000A's data pin to a digital pin and then I send out the signal. What I want to do is actually receiving the signal on the Arduino, i.e. which button was pressed on which remote (there are multiple remotes). For that I am using an XY-MK-5V and the Radiohead library. I used the RH_ASK driver sample code. However, it doesn't receive anything at all, meaning nothing is printed to the serial monitor.I think there are a couple of issues, i.e. it seem the Radiohead library expects a different preamble then what my remote sends and it also expects a checksum which my remote also doesn't seem to send. I haven't found a way to configure Radiohead so it can deal with my remote code. Is such a configuration possible. If not, what are the alternatives?

DIY Hue compatible objects

Hi,I love my technology and have attempted to build many small electronics projects with varying levels of success and completedness.I have an idea that I would love to put into action but having a lack of knowledge in ZigBee I wanted to put it to the community to see who else has a need and if anyone else has had any success with the aforementioned Hue system and a DIY ZigBee project of any kind.My idea comes from a need to make things simple for the family and guests in my home to use the Philips Hue system I have without having to re-wire the house. I would like to have a single push button that uses the ZigBee network with Hue that can do multiple things based on lengths of push and number of pushes etc. Much like the remotes can already. However I want to make it so you can put any kind of momentary push button on it.In New Zealand I use a very common style of switch plate made by a company called PDL. The plates have a variety of options and one of them being a modular system that has a push button available. There is even one that has a small LED on it.Having the ability to add a second module to my light switches that allows you to push the button for simple on/off functionality. Long press for dimming and multiple press for scenes or set brightnesses.Now i've coded for Arduino and used this on ESP modules but never done anything in the ZigBee space.Has anyone done something like this before?I'm not asking for anything to help me do this but rather pointers. I will continue to research this project and hopefully one day make something worthy of an instructable for all you kind folk out there! Happy building!
