aqua aerobics is great also and a lot of fun :-) Quite a tale .. so its for sale now again?ps: why’d u require ppl to login and even more why pages and no posts on your blog?? I’m just getting started with Arduino and wireless communications and found this extremely helpful. This may be old news to everyone else, but I hadn’t heard of these and would never have thought to use them if I saw them on SparkFun. It’s sad to see all the negative comments, because this is great information. I’d love to see more cheap or simple alternatives to expensive or overkill electronics. I was going to buy some XBees to play with if not for this article. For less than the price of one XBee module I can make a pair of transceivers from these. I feel your pain!! I have the MS Wireless Desktop Elite and have the exact same problems you have outlined. I too have scoured the web looking for a solution or even an explanation and have found nothing.I get a feeling it is to do with wireless interference as I was actually given this keyboard and mouse by a friend who upgraded to a logitech setup and they never experienced this problem. Changing channels on the keyboard when it starts happening usually helps for a while. Although if this is the case i’m confused as to why I never experience any problems with the wireless mouse that came with it… @j_jwalrusExactly what I was going to say!and @MarkIt’s iCrap! The punctuation matters.
