My desktop-PC's Motherboard just died yesterday... So maybe it is time to buy an all new PC!
What I have in mind is to try to build a Desktop-PC-Bot around a mini-ITX MB: It should be a desktop-PC when I am at home and a robot when I am out (or when i don't need the PC). I will use a commercial or homemade chassis and put outside wheels, PING, camera, and all other fun stuff for a robot, and inside the mini-ITX, the EZB, etc...
My concern is about power. I want a relatively good motherboard (like this one http://www.gigabyte.com/products/product-page.aspx?pid=4338#ov) and CPU (like this one http://ark.intel.com/products/65515/Intel-Core-i5-3475S-Processor-6M-Cache-up-to-3_60-GHz) and I think it will need at least a 300w alim. It is not a problem in PC (connected) mode, but I don't know if it will be possible to find a battery that will handle the whole system in Robot mode... What do you think?
Upgrade to ARC Pro
Synthiam ARC Pro is a cool new tool that will help unleash your creativity with programming robots in just seconds!
M4-ATX dc-dc conveter
better to look at the ZOTAC line of mini computers ,much lower wattage and up to I3 PROCESSORS
In robot mode, the GPU part of the CPU will not be used (no screen), and the only component active will be 1 SSD, EZB and robot parts... so probably i will need around 150watts at the end.
It should be more reasonable for the battery, right?
most ZOTAC are wellunder 100 watts ,like 40 watts and some 12 watts
Dont forget the bigger the battery high the torque of the motors
and less wattage of batteries less run time
SO best solution is to look for a low wattage mini -itx board that use low wattage and high speed as you can get
I5 core uses more wattage then I3 core
