Hi. I really like these ideas. Especially the equalizer. It seems to work really really nice. I love how you used those retro looking light bulbs instead of LEDs. However, I’d like to know about that custom SSR board that controls those AC bulbs.Also, how do you send the music data to Arduino? And does arduino just receive the music and then process which lights nee to be lit up? Or do you send that data from the computer?It will be really nice if you make an Instructables explaining only the equalizer. Or add more details here.Thank you.

Very well done. Feels really good to see Bengalis making such cool projects.I have a little suggestion. You could PID control for the line following. You'll be able learn PID control through it and your robot will follow the line much faster and accurately.

I don't have a 3D printer. Is it possible to make this without 3D printing? I think I will give it a try with plastic sheets.

That will let too much current flow through the resistor and damage it, may also damage your battery if it can't handle the current 4.2/3 = 1.4Amps

I did on one of my modules. and the range got halfed! I didn't change my code. What did I do wrong? I cut the old antenna connection, I did solder it properly. I checked with ohm meter and it shows that the 2 antennas are shorted. It shows the same on the unmodified one.

122mm length PCB costs a lot more than a 100mm length PCB. Is it possible to make the PCB 100mm?
- Iqbal Samin commented on GreatScottLab's instructable DIY Buck/Boost Converter (Flyback)
As he said in the video, the output is inverted and not referenced to ground. So you can't just use a voltage divider (unless you want wrong results)A differential amplifier will make sure that the Arduino always reads the voltage potential between the positive and the negative output. That op amp is being used as an differential amplifier.Hope you get the point.Pirthul.
Remove this line too:#define F_CPU 8000000
1. R9 is the load, not a resistor.2. There are two 100nF capacitors in the schematic. look closely. They are C1 and C2 on the top left corner, next to the voltage regulator.3. Where do you get these options? When burning fuse? If so, you don't need to burn fuse, you just need to burn the Arduino bootloader.

- Iqbal Samin commented on Rahul Mitra's instructable Homemade DVI-I to DVI-D Converter
This will work for DVI to HDMI converters because you are not cutting the digital pins and HDMI is digital.But this will not work for DVI to VGA converters because you are cutting the analog pins and VGA is analog.

Those capacitors looks like they're at the end of their life, I think you should change them, just to be safe.

- Iqbal Samin commented on danielrp's instructable Superb Lab Power Supply
Hey, nice instructables!I made a similar power supply with the same 30V 3A linear power supply kit as yours. After assembly it worked just fine, I used it for about a month to power my circuits, charge batteries etc. But since yesterday, the current control is acting weird. Normally it used to go up to 3 amps, but now it goes up to 8 AMPS! It blew the fuse that was connected on the secondary side of my 24V AC transformer. Can you please help me? I don't why it's happening.BTW, my voltage control is working. Current control is also working just fine, but it goes up to 8 amps instead of 3 amps, that's the only problem.Thanks you.- Prithul

It doesn't matter, it determines which way you have to rotate (clockwise/counter clockwise) to increase your voltage/current.You can swap them to change the direction.

Datasheet says 15 voltsThanks
- Iqbal Samin commented on GreatScottLab's instructable DIY Constant Current LoadView Instructable »
It will work, but it will get very hot since it has a high drain-to-source resistance. It will also cause some voltage drop, so the amount of current calculated by the op amp might not be equal to actual current flow, so use an ammeter to measure the current flow (I might be wrong about it)

Oh, sorry. Pin 1 isn't a PWM pin. Please change it to 5/6. (Pin 5 and 6 can provide higher PWM frequency)

- Iqbal Samin commented on GreatScottLab's instructable DIY Constant current load
You can increase the discharging current by increasing the supply voltage and using a MOSFET with a lower Gate-threshold voltage (Vgs).But remember, more discharge current = more heat = more danger! BE CAREFUL!!

Sorry, this code is not mine. It's written by GreatScott. I just changed it a little bit to make it compatible with ATmega328P.

This code is for ATmega328, not ATtiny13. If you want to use it on ATtiny13, you'll have to study its datasheet.
- Iqbal Samin commented on GreatScottLab's instructable DIY Boost Converter || How to Step Up DC Voltage Efficiently
I found a solution. If you want to make it with Arduino UNO, or any other Arduino with ATmega328, use this code:int pwm = 1;int potinput = A2;int feedbackinput = A3;int potinputval;int feedbackinputval;int pwmval;void setup() { TCCR0B = TCCR0B & 0b11111000 | 0x01; pinMode(pwm, OUTPUT); pinMode(potinput, INPUT); pinMode(feedbackinput, INPUT); digitalWrite(pwm, LOW); pwmval = 0;}void loop() { potinputval = analogRead(potinput); potinputval = map(potinputval, 1023, 0, 255, 0); feedbackinputval = analogRead(feedbackinput); feedbackinputval = map(feedbackinputval, 1023, 0, 255, 0); while (potinputval > feedbackinputval) { if (pwmval == 230) { potinputval = analogRead(potinput); potinputval = map(potinputval, 1023, 0, 255, 0); feedbackinputval = analogRead(fe…

imho that doesn't make any sense. Because you are using a non logic level MOSFET at logic level. It will have higher Rds than a logic level MOSFET would have which is specifically designed to work at a logic level.
IRFZ44N is not logic level. IRLZ44N is. IRFZ44N barely turns on at all at 5V from my previous experience. Maybe you're mistaking between IRLZ44N and IRFZ44N
