I was just looking at your excellent update to box2dweb that adds rope joint functionality … then I saw this! Your arduino wireless comms. I’m also playing around with arduino … to make a masthead wind speed and direction sensor and sender including accelerometer/gyroscope compensation. I’d be interested in your wireless method. I’m looking for a range of about 10 to 15m.
By the way, I need the rope joint to simulate boat anchoring … with a ‘cable’ that consists of sections with different mass/density eg. the anchor is connected to a 10m long chain that is connected to 5m of heavier chain that is connected to 30m of rope … to the boat. Appreciate any hints on how to join ropes of different densities in box2dweb.
please ignore my dumb question about joining different ropes. It was obvious when I looked at your demo code. Thanks for that 😉
The main challenge with cheap wireless communication is the accuracy of the data. Depending on your requirements you can get away with a method like I used above.
About $3 worth of components! Can’t argue at that price.
I was building a prototype of a remote motion sensor. The product would require a low price point which I was able to achieve. But the information is binary so I had it easy!
By the sounds of it you are just making one item? If so then I would spend the extra coin and get a zigbee module, they are really simple to implement, and handle all of the nitty gritty details.
