Development board for ATmega8.....
« on: January 12, 2008, 11:55:03 PM »
I tried making the circuit given in the $50 robot,but was unsuccessful as i didnt get all required things....
So i googled for a development board and got the following one....
Pls tell me if this can be used for programming ATmega8 ....

nope, you need an additional programmer

I just got this in my email today. It looks decent, although it lacks a power bus for digital components. You might like this more.

We could use the bare board or the kit from this place
http://www.moderndevice.com/index.shtml

He also sells the AVR chip with boot loader pre-installed, which would
mean that we don't have buy the serial dongle and just use the
USB-serial converter like the one you have got for the pioneer.

Its just another option and pretty cheap too at about $15/board without
the USB-serial cable. I will come to the event, but probably will not
build one though, I have enough and more of such boards already.

admin, if that board costs $15 and usb->serial costs $15-30. wouldnt it be better off getting an aurdino? or maybe an axon  ;D
Problems making the $50 robot circuit board?

Agreed, I wish the BBB had power and ground bus for the digital pins.  If you've got a serial port, you can use the P3 serial adapter for only $5.  Its easy to solder together.  If I can do it, you can do it for sure.  You'll be locked into their bootloader if you don't have an ISP programmer though. 

It has the following benefits that swayed me in the direction of building these for my project.

1)  Small size.  A bit smaller even than the $50 robot PCB.  Development boards like the 500 are quite large.
2)  Breadboard compatible
3)  Arduino libraries make it a snap to get started programming.  Can use the lower level WinAVR libraries or even C++ if you wish.
4)  Come disassembled, so I can place the headers where I want in the direction I want with the gender I want.
5)  Not so much soldering.
6)  Cheap when ordered unassembled, leaving room in the budget for other things like the Sharp sensor.

I'll be building shields in the next few weeks for mine so I can get the servos hooked up.
