The Seventh week’s class of my fab academy life took place and the professor Neil class started as usual,this week assignmend as khown as 3D Scanning and printing

Group Assignment

In this week, we learned to use different electronic test equipments.

Testing Equipments

FLUKE 101 Pocket Digital Multimeter

it measures AC/DC voltage, Current, Continuity, Resistance, Frequency, Capacitance

INSTEK GPD-3303D Power Supply

Instek GPD-3303D is a Multiple Output Programmable Linear D.C. Power Supply it have 2/3/4 Independent Isolated Output, LED Display, 1mV/1mA(GPD-2303D/GPD-3303S/GPD-4303S), 100mV/10mA(GPD-3303D) 4 Sets Save/Recall, Tracking Series and Parallel mode, USB Standard Interface, and Lab view driver

UNISOURCE DS-1100 100 MHZ, 2 CH, Digital Storage Oscilloscope photo_2022-03-09_19-15-47 (2).jpg

The digital storage oscilloscope is an instrument which gives the storage of a digital waveform or the digital copy of the waveform. It allows us to store the signal or the waveform in the digital format, and in the digital memory also it allows us to do the digital signal processing techniques over that signal. The maximum frequency measured on the digital signal oscilloscope depends upon two things they are: sampling rate of the scope and the nature of the converter. The traces in DSO are bright, highly defined, and displayed within seconds. it have 100 MHz bandwidth, 1 M Memory, USB storage, RS232C & J45 interface,4000 point record length for each channel,Multi-waveforms math, FFT Function, Cursor & Track measurement, Waveform Record & Recall, Trigger Mode for Edge, Video, Pulse Width, Slope & Alternate

INSTEK AFG-2100/2000 SERIES ARBITRARY FUNCTION GENERATOR

https://fabacademy.org/2022/labs/kochi/students/joshwin-johnson/images/photo_2022-03-09_19-15-47.jpg

A function generator is a specific form of signal generator that is able to generate waveforms with common shapes. Unlike RF generators and some others that only create sine waves, the function generator is able to create repetitive waveforms with a number of common shapes. The AFG-2100/2000 Series Arbitrary Function Generator is a DDS (Direct Digital Synthesized) based signal generator designed to accommodate the Educational and Basic Industrial requirements for an accurate and affordable signal source covering the output of Sine, Square (Pulse), Ramp (Triangle), Noise and Arbitrary waveforms.it have 0.1Hz to 25MHz with in 0.1Hz Resolution, Sine, Square, Triangular, Noise and, Arbitrary Waveform, 1% ~ 99% adjustable duty cycle for Square Waveform, Waveform Parameter Setting Through Numeric Keypad Entry & Knob Selection, Amplitude, DC Offset and Other Key Setting Information Shown on the 3.5” LCD Screen Simultaneously, AM/FM/FSK Modulation, Sweep, and Frequency Counter Functions (AFG-2100 only), PC Arbitrary Waveform Editing Software

Let’s start

In this week assignment is Electronics design is known as we make circuit PCB using micro controller, LED ,and switch. so I started the work

In First I explor the previous studentes documentation in I watched in ............... Then i give the basic idea in this week assignment

In first task is design a circuit, Then I chose the software is Autodesk Eagle in Eagle new updation attached for fusion360, So I open the Fusion360 and take the Electrical design This is the Eagle First window Then open the new schemetic Opend new page

Then I take library and Browse the new library becoaus We used micro controller is ATTiny 412 this libary is not give in fab library so I browse it and fab library

next started the circuit designing take the add parts Add ATTiny 412 and Fab library Then select the wanted parts using the name and pictuers Firts I select the ATTiny 412 Then I selected the switch on fab library Next selected the LED I connect with three LED

Then select with resistors and capacitor

Then I selected in 6 pin header and open it

Then selected the 2*3 SMD pins Next I take the capaciter

The lines are connected in the possitions

Then add the names in all points for the circuit connections

This button is to switch the screen in pcb circuit mode

Then I arrenged the circuit in the possitions

Then next selected in the Drc tab I start to arrange the Drc tab in this tab is used to arrange the milling prosses

I arranged this Drc

Then next I take to draw the routs connecting, this methodes are used

This is the circuit connection rout gets Then next arrange the PCB boarder then I open the 3D design

Then selecte the scketch and arrange the size of boarde

Then Draw and arranged the scketch

This is the final result

After that I Add a simpol in the PCB using the inkscap

Then start my PCB milling prosses

This is the photos in the modes

Milling prosses is start The milling is also completed ,after that I take it

This is the final result

I thake the componens and solder it This is the final result

Then after that I started the programming

I coonected the jumper wire with my UPDI programmer

I programmed it using arduio software this is the serial print final result
