Recently embarked on a journey of making my own chip. It is a chip that will blink a LED based on the input voltage. It has a few version about which I have given the details of below!
(More details:)
LBseries
The LB chip is a small chip concept that will flash the LED based on the voltage applied to it. Uses only a few components and can be made easily. This repo consists all of the changes, basic components, updates and other details related to the project.
More details about the maker and this project can be found at https://www.esccrasci.in and at www.youtube.com/c/esccrasci
This chip has 5 versions:
V1.0.0-The very first version
V1.0.1-2nd edition with minimal changes
V1.0.2-3rd edition with better structuring but with major flaws
v1.0.3-4th edition with physical changes but with fatal circuit flaws.
V1.0.0
Basic version with single LED flashing capabilities.
Pros:
Can flash the LED at different frequencies based on input voltage
Small size factor only taking 10-12cms in area.
Cons:
Bad timing and frquency control
Structural issues-size-alignment
Voltage vulnerabilities ( cannot handle 1 volt higher than 20 volts)

V1.0.1
This is the second changed version with many major improvemnets but with the addition of different flaws
Pros:
Can flash the LED at better frequencies which are accurate
Mild reduction in voltage consumption
Size made smaller in X and Y axis
Can work with voltages between 11-20 volts
Cons:
Cannot handle high volatge and high current LED’s
Voltage change can be fatal if increased above the limit
Cannot work with SMD LED’s due to sudden changes in the voltage

V1.0.2
Third change of the chip with structural changes.
Changes:
Chip is mounted on PCB with better rigidity
Pros:
Stronger, harder and easier to use
Large footprint
Better frequency control
Cons:
Large size, canot fit on breadbpard without bending of legs
Bad voltage control
Excessive resistance between connection points.

I took a video of the first version and here it is!
