Title: $50 robot on sale? and other questions...
Post by: SmAsH on March 01, 2009, 12:44:14 AM
ive seen a few topics of people saying they're going to sell the board and possibly also the $40 board, has anyone done this yet? i was thinking if no one else has done this i might have a go (with the respective creators permission of coarse). what do you guys think?

side note: does anyone have the eagle board file for the $50 robot with only one power supply?

side note 2: would this atmega8 be the one for the $50 robot? http://www.futurlec.com.au/Atmel/ATMEGA8.jsp
its the only one i could find in an australian online store.

If I wanted to invest in you and your product:-

1/ You dont quite know which ATMega8 might be suitable as per

2/ You are requesting other peoples Eagle designs. So you dont have one - but you want to sell anything that other SoR members give you for free. Are you comfy with that?:

Sorry, but I'm not quite sure what 'value added' you bring: other than publishing other peoples designs

Well I've made the Roboduino board = thats 100% compatible. I've even made a modified $50 Robot Tutorial for the Roboduino

Also, if you do the math, the roboduino will actually be cheaper than a $50/$40 robot board. Curious Inventor can buy in bulk, resulting in cheaper prices.

yes you have a point about the bulk part. i priced all the parts for the $50 board at about $27au which is about $20usd? and webbot i take it you dont want this to go ahead?

Factor in the PCB cost, shipping, and the fact that there is no USB programming... not really worth it.

... and webbot i take it you dont want this to go ahead?..

Thats not quite what I said. The bare bones $50 board is: one IC, one regulator, one capacitor and whole load of header pins. There's only so many ways you can put it together!

Not being rude about the $50 design - just a testament that it is sooooo simple - ie it fulfills its design requirement as a noob board.

It's hard to know what to add. Airman did a great job with the Roboduino to produce a board filled out with extra interfacing/loader features etc

So I wish you well - but I think you have an uphill ride to come up with 'yet another' beginner board. You will probably spend $1000s in the prototype iteration phase with your manufacturer (standards like rohs for example?). So what added value will your board bring on top of say: a homemade $50 board, a Roboduino? If it costs near $100 then I'd be better buying an Axon. My confidence was dented when you were asking other people for Eagle designs for 'your' board !!

Bon voyage
