OCCED7300 Final Paper

Well another successful end to a course, after much request I am posting my final paper. Just to give an idea what to expect in write a college level paper. This is probably no my best writing (I think my worst paper ever) but it will give some ideas.

This paper is totally theoretical, opinionated and not finished. I was limited to ten pages but with all the steps and info involved I probably could of wrote a book on how to expand a new shop.  

Background: In this research paper we will take a look and see if our school needs to expand our current engineering elective to a new full-time Biotechnology program. We will also look into current steps being taken to carry out this additional curriculum to the Engineering Programs at our school.

Clock-It Kit Clone

Burning an ATMEGA328 Clock-It kit form spark fun using AVRDUDE and the USBtiny by Adafruit. I copied the firmware in the original kit and cloned it to make more kit, we redesigned the board to a single sided PCB with 9 jumpers. This made it easy for students to mill out on our T-Tech milling machine.

Come to find out there are three hex files you need using AVRDUDE, the main program  hex file and lfuse and hfuse configure memory hex files. Most of the time I just copy with a universal programmer simple one click but this time it the programmer was broken. So with the usbtiny was a simple connection to the ISP bus. 

Here is my redesign of the Clock-it Kit, note there is no ISP connector so programming it in circuit is not possible.

Find and test communications to chip

sudo avrdude -c usbtiny -p m328p

Erase Chip

sudo avrdude -c usbtiny -p m328p -e

Burn Main Hex file program

sudo avrdude -c usbtiny -p m328p -U flash:w:clockit-v11.hex

Burn Fuses

sudo avrdude -c usbtiny -p m328p -U lfuse:w:0xe6:m -U hfuse:w:0xdf:m

Fixing a refrigerator

Fixing my brother in-law fridge, There was no water going out the front door or ice being made, Come to find out the water valve was burnt out. Got a nasty surprise trying to figure out the water shut off valve, who makes a valve with no markings for on and off, got sprayed with water pretty good. DOE!
