For my university embeddded project I need to make something electro mechanical and programmed ie pic, electronics and something that does something.
Mine will be a radio or wire control cat or dog that pees and does other things as I have an interest in special effects.
I am clueless about radio control... form what Ive picked up though you need a transmiter, reciever, battery packs and servos... 2.4 systems are better as lock onto one reciever and transmitter. More channels are good.
I have no idea how brands compare or what I should be looking for in a purchase on Ebay
these are some I have been looking at
Also some were described as missing ariel how hard and expensive is it to replace these, what all will I need, can any servo work with any controller, what should I ask sellers, whata a good deal and what should I avoid? etc
As said looking intially at my project but then looking to use this for other effects projects etc. Plus a few pranks
Also what is a good way to merge this with a pic project using a PIC 16F819
Advice please asap as eyeing up various deals on ebay ending soon
