Is the IC or micro controller the only tough nut to krack in this? If so then, how hard can it be to just change the microcontroller with our own programmed version ? pardon me as my questions may be silly due to lack of specialised knowledge on the subject. | ||

No point in reverse engineering one- it'd be more work than to just learn how to do it from scratch. Just learn the basics of PPM radio system and build one of those. From my understanding it is almost as simple as you can get for RF. If you are trying to save money, then no need to go PCM or spread spectrum or anything like that. http://www.omegaco.demon.co.uk/mectnpdf/mectn004.pdf Is the radio supposed to be $35? Or is the whole rock crawler+radio supposed to be $35? Because you probably could get the radio to be $35 to produce, but I doubt you could get the whole kit to be that much. But can you beat this one? Hobbycity Online R/C Hobby Store : Hobby King 2.4Ghz 4Ch Tx & Rx (Mode 1) $29.99) It's not hard to replace the MCU if you know where all the pins go- but you don't know where all the pins go and chances are you won't be able to find out on their multi-layer board without schematics even if you had the board in front of you. Also...don't forget you have to do the same thing with the receiver. You'd have to reverse engineer both. Not worth it especially since you are trying to go for cost, and those guys are usually more feature oriented. You'd have to slice through a lot of the fat to find what you want. You don't seem to have the proper knowledge to design your own radio system, let alone reverse engineer it (which is harder and more frustrating). You're going to have to learn the material or hire someone who knows it, and in both cases once you know what's going on it would be easier to just design it from scratch.

^ sweet, I hadent seen those. I don't know about him but it should work for what I'm doing. It would cost less than the parts to build anything similar. I'm sure its not the best, but I'm not building a long range thing anyway.

Here in the UK, the cottage industry was killed off becuase of government red tape and having to meet all kinds of approval/certification. Looking ahead, if you plan to export, again you will need to meet certain standards... So have you considered all of this as part of your business plan? Assuming you have one.....

Its intresting to know that you are working on how to make RCs. I will definately look forward to the tutorial. Thanks a lot! | ||

This is going to be pretty hard. But at my company if we want a plastic casted part made in mass quantities we often have it done in India. So maybe he has easy and relativly cheap access to that kind of thing?

Thanks for the pdf, I will go through it. The whole rock crawler , that means rock crawler + radio = $35. I know if I have the design for the radio, then I will be able to get it manufactured very cheap & hence achieve the target price of the product.

That doesn't seem likely to me, where do you get that information from? If the discrepency is really that high then you have a chance, but the profit margins I've seen rarely exceed 40% in the most profitable of manufacturing industries.

If you know, the worlds cheapest car The TATA NANO is manufatured by the TATA group . The price for the NANO is $2000 +taxes extra. Its a four seater & the body is complete metal.

the radio I am sure I will be able to manufacture it cheap if I suceed with the design.

Its an Important point you have noted. Since at this point the whole picture is yet to be cleared, I cannot jump onto conclusions unless I have the process freezed. It is definately possible to keep up to the standards & give economical price if the manufacturer is ready to make a bit less profit otherwise.

I guess I don't expierience that kind of quantity manufacturing, so I can't say for sure. The place I works for makes the worlds largest shovels and draglines, we crank out 50 machines a year and even our most popular model only makes 26 a year. So for us it is always cheaper to buy specialized things from someone who always makes them, and just build the bulky stuff ourselves.

Reverse engineering commercial product to make them cheaper in sweatshops in india all in the doubtfull but 'warm'n'fuzzy' intent to bring smile to less fortunate child (is it by the toy or by the salary from the sweatshop ?) Is not exactly legal in my book. That's even stranger since the RC field is quite old now and you can find or if you'r a little smart design by yourself an RC set. And of course to keep it classy the poster don't forget to critic the profit made by the original manufacturer. Who by the way spend also some money on the R&D instead of trying to steal another company design. CDMA phone for 0.5 cents... yeah... sure... It don't even cover the Qualcomm license fee...

As I stroll thu the endless shelves of toys at WalMart, most of which use technology in them somehow, I come to the remote control devices shelves. They have fully proportional remote control EVERYTHING...cars, boats, UFOs, planes, subs, tanks, spiders, helecopters...etc etc...and the most expensive one is around $29.00. MOST average arounnd $15.00, and the none-proportional rc cars (push button to turn left) are around $6.00. How do they do it???!!!...they sell MILLIONS of each of these WORLD WIDE. So how exactly do you plan to beat this market?...it would seem as though inexpensive remote-control for the masses has already been covered. Reverse-engineering the electonics seems to be the LEAST of your problems compaired to designing,engineering, prototyping, moulds, manufacturing,boxes, advertising,and most importantly DISTRIBUTING! Not to kill off a dream....but lets get serious mate. Last edited by bigkim100; 13th June 2009 at 10:28 PM. | |
