UM66
The brain of this project is UM66, which has an On-Chip ROM programmed to produce musical notes. The UM66 consumes very little power and can be operated with just 1.3 V to 3.3 V DC power. It can be used in various applications, such as doorbells, telephones, toy applications, and alarms.

UM66 variations
UM66 comes in various song lists. Here is the list that you can refer to while purchasing the IC

Use the below circuit only when supplying the circuit below 3 Volt DC Power Supply.
Use the circuit below when the input DC power supply exceeds 3 Volts. In the circuit below, the Zener diode has been used to protect the IC from overvoltage. Only the 3.1V Zener diode has to be used. The other way to protect the circuit is using a 3V Voltage regulator.
In this post, I will show you how to crimp Coaxial cable using an RG6 cable or RG6 Connector to connect Satellite or Cable TV.
Coaxial Cable or Coax Cable
Coaxial cable is used to transmit radio frequency signals between transmitter & receivers. For example, RG6 cables are used to transmit signals from satellite to TV receiver.
In the below image, you can see how the coaxial cables are composed
Center Conductor - Copper-plated steel wire for TV operation
Dielectric - Insulator surrounding the inner conductor used to maintain distance between conductor & shields
Foil Shield - To protect from RFI interference and signal loss
Braided Shield - To protect the signal from EMI and signal degradation
Outer Jacket - To protect the cables
Crimping Coaxial Cable or RG 6 Cable with RG 6 Connector
If you prefer watching a video tutorial you can click here to watch it on my YouTube channel.
First, strip the coaxial cable as shown in the below image using a coaxial stripper. Affiliate links to the tools will be shared at the bottom of the page.
Install the RG6 connector into the coaxial cable.
Using a coaxial crimper, crimp the connector.
Finally, trim any excess center conductor to complete your cable.
To get WiFi on your desktop PC or a laptop, first, you guys need to purchase a USB WiFi adapter like this one Amazon US or Amazon IND. In my case, I have purchased the TP links nano wifi adapter, which is a low-cost dual-band (2.4 & 5GHz) USB WiFi adapter.

To set up the WiFi, first, you need to download the driver from the TP links website or use the CD which comes along with the package
To make an Instagram grid to display on your profile, the First thing you need is a square image. The reason for this is, the Instagram grid is square and if you choose any other image size, Instagram will auto adjust to fit the grid shape that is square and the final product won't look good. For this reason, I will be choosing 1080 by 1080 pixels as my single image size, and this size also happens to be one of the popular Instagram image sizes.
Next, we need to calculate what size should be our Instagram grid image. To do that, first, choose the grid look that you want. For this tutorial, I will be using a 2*3 grid.
Now to calculate the Grid Image size, we need to add each single image size. Since I have chosen my grid has 2*3 and my single image size has 1080*1080, my grid image height will be 1080 * 2, which is 2160 and my width will be 1080 * 3, which is 3240
After the calculation, open the GIMP image editor and click on File and then click on New
Next, enter the image size. In my case Width will be 3240 and my height will be 2160
Next, click on the Advanced option and set the option 'Fill with' to Transparency and then click OK.
Next, go to Image, and then click on Guides and then select the option New Guide
Next, set the direction as vertical and position value to 1080 and then click on OK
Now repeat the same process, but this time change the position value to 2160
Next, repeat the same process as earlier, but this time set the direction to horizontal and change the position value to 1080
After setting up the guides, drag and drop an image and adjust the position of your image as you want
Next, go to image, and click on 'Slice using Guides' which will create six different images with the size 1080 by 1080 pixels
Next, export the images in reverse order and name them starting from 1. To make it easy for you guys, I have numbered them, so just follow the order.
Next, transfer the images to your phone and upload the images one by one starting from 1.
Note: Do not upload all the images at once. If you upload all the images at once it will create a multipost post and you won't get the grid look
Once you have uploaded all your images, your Instagram grid should look something like this.
