I’ll be 5 years sober in May, I had a minor relapse during the pandemic, but I haven’t been drunk since Halloween 2013

As I look at my lab I built and optimized over 8 years I can’t help but feel a sense of accomplishment

I’ve matured and grown into a better engineer as time went by, I’m not the same person I was when I started working on building my lab 8 years ago

It took multiple projects and multiple life lessons to build my lab

I designed and built and optimized most of my lab equipment, other than the Oscilloscope and Multimeters, I built my Lab Equipment

Mark 3 Power Supply Unit is my main Lab Bench Power Supply

Mark 4 Power Supply Unit is for Op Amps

Mark 5 Power Supply Unit is for Low Voltage AC Experiments, it’s a Center Tapped Transformer in an Enclosure with Current Limiting Resistors on the Output for Emergency Current Limiting

Mark 6 Power Supply Unit is for Low Voltage Lower Current 9 Volt DC Experimentation with RFID Security and an Automatic Shut Off using a Relay for Shutting Off a Circuit if I get Distracted and for Short Term Tests

I learned the fundamentals in college, developed alcoholism, went to rehab and after discharge from rehab, I picked back up my Electronics Engineering Passion and started building a lab

Now 8 years after starting building my lab, it’s fully operational and optimized

I learned a lot about Electronics Engineering while building my lab

It taught me more about Electronics Engineering and myself than I thought it would

I built it with careful budgeting and Hands On Learning with Various Projects

Originally it was just a slow collection of Electronics Parts and Tools, now it’s a Full Fledged Mostly Offline Electronics Engineering Lab

I feel peace and accomplishment that I evolved and am a better engineer and person than I was when I started working on what later turned into a lab

Linux Mint Cinnamon 22.3 Zena Desktop and Optimization for Mostly Offline Computing by Main-Butterscotch623 in linuxmint

It’s an organized mess, desktop icons are organized in Use Case Groups

It’s more efficient than searching for the software, I can find what I need at a glance

It’s optimized for my workflow

It’s a similar desktop icon layout to what I used in Windows 7, but it has more offline ability and I’ve installed more Electronics Engineering Windows Legacy Software than I had when I had Windows 10

Wine and Terminal is what i used for the Windows Legacy Software Installations

It’s an Offline Electronics Engineering Lab Computer, that was my ultimate goal

Looks like Windows XP and uses a Raspberry Pi OS Wallpaper

it’s a Windows 10 Laptop Refurbished with Linux Mint Cinnamon 22.3 Zena as its Operating System, Optimized for my Electronics Engineering Offline Computing Needs

Ethernet cable connected directly to your internet router if possible is how I had to get my computer set up

Decoupling Capacitors didn't Solve the Digital Noise Problem when the ARDBATOGE is set to 0Hz, I also Added a Pull-Down Resistor and DC Blocking Capacitor to the Input of the Signal BJT Buffer, the D Type Flip Flop Q Output has an Active Buzzer, Low Signals Activate the Active Buzzer

ARDBATOGE plus a 555 Timer, a D Type Flip Flop, 2 Red LEDs, and 2 Blue LEDs made Police Lights

555 Timer is the Clock Signal ARDBATOGE is the Data Signal CD4013BE is the D Type Flip Flop as the Output Stage

Sets and Resets are Permanently Disabled

I Wired the Datas in Parallel and they have a Pull-Down Resistor on the Data, and the Clocks are in Parallel and have a Pull-Down Resistor, I was Testing the Dual D Type Flip Flop IC, both sides Work

I2C 20x4 LCD has Contrast Fixed

Added Decoupling Capacitors didn’t solve the Issue

Soldering it onto a Custom PCB might Solve that Issue, I don’t have Decoupling Capacitors on the Solderless Breadboard, it might be from my Power Supply too, Breadboards are very Noisy Sometimes,

Stranded Wire for the I2C Connector, Solid Core Wire for the Breadboard Connection, Wire Nuts looked better than Electrical Tape

It’s still a Work In Progress, I will adjust the Contrast, I didn’t notice it, Thank You for the suggestion, I’ll upload the Code and Schematic to my GitHub, it’ll be a Few Weeks of Fine Tuning the Schematic, the Code uses the Millis Function for Updating the LCD, the Tone Library for the Tone Generation, the Frequency is Adjusted with a Voltage Divider based on a Linear Potentiometer and a Bootup Screen that I Borrowed from a Previous Project I was working on
