How to make your own IC! (Integrated Circuit)

May 23, 2021 - Reading time: 7 minutes

So I have finally finished making the chip after 3, mostly successful attempts.
So the thing is that the chip I made follows the principle of a real chip i.e. I mean that it uses transistors as its brain.
It is a single transistor capacitor based IC. It is also called LB103 (3rd version).
What it does is that it blinks the LED based on the voltage and the capacitance. What I did was that I used a capacitor of value 407 microfarad. What I found was that the chip was very bad at blinking the LED accurately. Even a change of 1 volt causes it to stop blinking for ever. Even with my very accurate (sarcasm) power supply, it was a blast trying to make it work. But I did it and recorded my adventure making and trying to use it.
But I am going describe its construction here.

The materials I used were:

  1. BC547 (NPN transistor)
  2. Proto Board
  3. Resistors

( I am assuming that you have most of the basic components such as a soldering iron and a lead roll.)
Making the chip:

Step 1:

So I started with the smallest piece of protoboard I could cut using a knife. Then I cut of the base pin of the transistor. I did that as the base pin is not required for the configuration.
Then I soldered the transistor in place.

Then came the capacitor. Unfortunately I used a capacitor of the capacity 407. But if you are also going to attempt this, I sincerely suggest that you use a capacitor of value 100 or anything below 400 or a capacitor of capacity 1000. Also get a branded one mostly from Murata or any other established brand. Then I soldered the capacitor in place. In the first 2 iterations I used a defunct brand’s capacitor (capapower) and the chip was very accurate but the transistor was not. So it was still useless as it was equally inaccurate. This time I used some transistors from TI and the capacitor was inaccurate. But I somehow finally got it to work in the end.
This amplifier is extremely easy to make and only costs about 1$ (if the components are purchased in bulk)

Moving on,
Then I needed to add the legs that made it look like a chip. Before that I would like to tell you that I made a huge mistake when cutting my PCB which will be highlighted by me in the video check it there. Due to which the chip’s legs were not aligned properly and it did not fit properly.
For the legs I used 2 resistors of a type I never used. And then I finished preparing the legs.
 Sorry, Img not available
Then I finished the circuit and it was ready. Then came the problem I mentioned before. So I had to adjust the legs of my circuit and then It was ready for testing. During my test I noticed that the chip only worked with 12 volts and it stopped functioning with 13 volts. But I got to work and here it is:

How you can make your own cube solver-PT2

May 22, 2021 - Reading time: 4 minutes

Now that we finished one part of the cube solver we move on to the second part where 75% of the project gets over. All of the popsicles together will form 6 pieces like this.
 Sorry, Img not available
Then when we fit all of them together the cube looked like this.
 Sorry, Img not available
Once that was over, we sanded all of the pieces.
 Sorry, Img not available
Quick tip for the people who feel/ and really are “broke”and/or cannot afford or have a sander:

  • Take a simple 10000RPM geared motor.
  • Get a fitting wheel for the motor.
  • Then get a 10000 grit sand paper piece and then paste it on the wheel with super glue.
  • Your simple electrical sander is ready.

So once we finished sanding we painted the product so that it remained beautiful.

Now we tried fitting the pieces to the cube with the center pieces removed. We also tried solving it to make sure that the cube moved fluidly.
(Special thanks to Kesshav A.V. for collaborating.)

Then we made a simple output design so that we had a simple design of the output.
 Sorry, Img not available
Then we attached wheels to the rods . Once we did that we attached the motors. Then we added geared motor wheels. Then we attached all of the motors to the wheels. Then we cut 3 pieces of cardboard with the following dimensions

In the next blog the circuit an the finishing will be covered along with the circuit diagram.
We are happy to say that pt3 will be the end of the making of the cube bot. Thank you for reading. Please keep checking this blog so that you know when pt3 is added.

How you can make your own cube solver-PT1

February 21, 2019 - Reading time: 4 minutes

For more than 2 years I have been dreaming to make my own RUBIK’s cube solving bot. Now, I have the materials and the tools to make it possible. There are 2 methods to make the bot solve a cube:

  • Push and twist method
  • Rotate side method.

The 1st method uses the least number of components possible. BUT it takes more time to solve and is more time consuming to code.
So, I used the 2nd method instead where each side is moved individually. This is easier and any motor can be used.
So I joined with my friend and started the bot.
Incase you wish to buy these products, the links are given below.

  • Ice-cream sticks
  • Super Glue
  • Template: Link below!

We first took a bag of ice-cream sticks. Then we made a simple template and cut the pieces. If you wish to replicate the same, the file will be given below. Then we cut the necessary pieces out with the help of the template. Then we stuck them together (see fig:cb1).

Then we made it like a tube. See fig:cb2
 Sorry, Img not availableOnce we did the above step, we tried fitting it to the center piece and check if it was steady. See fig: cb3.
 Sorry, Img not available
Then we the same few steps listed above and made 6 of those tubes mentioned above. We also kep’t testing to see if each tube fits. See fig:cb4,cb5

Once we finished all of these steps pt1 of our bot was ready.
You can move to to the next blog which will come soon so that you can complete making the cube solving robot. Please keep checking the main page so that you know when the next steps come.

Make your own Hydrogen Generator for cheap!

February 10, 2019 - Reading time: 4 minutes

This is my electrical and chemistry based project. Highly recommend that you don’t try this at home with out any safety equipment.
Check video below.
Click Here To View!

Now we used small electrodes with a fixed voltage. Adding higher amount of electrodes can get lethal. SO PLEASE DON’T TRY THIS AT HOME.
Incase you want to make it for other purposes here are the items required:

  1. A zinc nail
  2. A copper rod or something made from copper
  3. A 12 volt powersupply:
  4. 9 volt battery
  5. a bottle
  6. Salt
  7. water
  8. aquarium tubing

Let’s start!

  • you gather the components with wire, attach 1 wire to the copper rod and 1 wire to the zinc rod,
  • make 2 holes side by side on the bottle
  • gather some clear aquarium tubing
  • Make 1 small hole and 1 big hole in which the tube can fit.
  • now attach the tube and fix the tubing with some E6000 or something (not sponsored)
  • Into the second hole, push the wire and electrodes side by side.
  • make sure that the electrodes don’t touch each other.
  • Now give it power somewhere in between 9-12 volts.
  • before that add some salt water to it till the electrodes

VOILA!now that your generator is ready, if you keep a lit up match near the tube, the match should turn of. If not add more salt or water accordingly.

The Very First Project I made (You can too)

August 13, 2016 - Reading time: 5 minutes

This is the very first electronics project that I made and uploaded to youtube.
This project is a Remote Controller based motor driver.
The video has the products needed.

The items needed to accomplish the task are:

  • RC receiver
  • RC transmitter
  • Motor

Or if you want to go ultra cheap you can get a cheap car and salvage the parts from it
Now for the instructions:

  1. Take the receiver and solder 2 wires to the motor 1 / motor 2 socket
  2. Use a multi-meter and a battery to find the positive and negative.
    • SOCIALL tip:
    • for seeing which connection is positive or negative, try placing the probes on the wire. If you don’t see a – sign it means that the polarity is correct else it is not correct.
    • See Image:
    • img not available
  3. Now that you know which one is positive and negative, connect your motor accordingly.
  4. Give it 3 volts with the help of a dual 1.5 volt battery holder. (pay attention to the polarity).

Your motor circuit is ready.Pressing the button will run the motor.

  • if your motor does not run try checking the polarity of the battery and the motor.
  • Check if your transmitter has batteries installed.
  • Check if your board is working
  • Checking if your transmitter works with something else.
  • Check that there are no short circuits.
  • Clean the flux on the board.

if your motor still does not work you might need to replace the parts.
