WEEKLY ASSIGNMENTS

Electronics Production

I got Zero experience in Electronics, I know in general the general names and what they stand for, and so to work and build an ISP to do something, that’s a new thing I need to add on my list to do. So the first test for the ISP was a demo run by our instructor Sibu, especially his way to change the milling head. Plus explain the major parameters.
Then Setting up the milling Machine Coordinate system(X, Y, Z) and understand the parameters for it.

I start working with a number (parameters) and I found out this is a good number to run
1- Speed mm/s 4
2- Cut depth mm 0.1
The result was excellent from my side even I clean all the other unused copper

components:

Getting back to web Doc. ( Building the FabTinyISP)
Software Installation
sudo apt install avrdude gcc-avr avr-libc make
Get and Build the Firmware
Download the firmware source code
Run make. This will build the hex file that will get programmed onto the ATtiny45
Program the ATtiny45
Edit the file called Makefile.
PROGRAMMER ?= usbtiny
save it
Run make flash.
Run the make fuses
Type lsusb in the terminal
you see a "Multiple Vendors USBtiny"
run make rstdisbl

During all the above setup I face a major issue, it was the USB Uiny wasn't working right on my computer and the ( "Multiple Vendors USBtiny" ) some times it shows is the terminal on other computers, a sometime it don't, the feedback from our istractor to check the conection ( soldering isn't right ) there is a loess in conection, I try to look at the coniction and I found out that one of the diodes is not conicating right, I re solder it againg, try to see it is fixed ... still, i have the same thing, then we found out that one of the 49Ω resistors is brocken, i change it, still same thing is't not working right ... I kept on trying to find out where is the miss connection did not found where is it. our instracor insist that there is a missing links in one, two maybe more, the soliltion to resoilder the parts again.

Problem solved it is working finally
