@@CowenTan-h6i Thanksfor sharing the video to reach wider community 👍

Thank you, Raymond! This piece of work will be applied for atmospheric pressure plasma jet. Wrap up warm for autumn :)

Thank you sir. Just an afternoon hobby try out :). Have a nice day too.

Thanks for watching! I have designed some nice pcbs in easyEDA and fabricated in JLCPCB in China. I don't need to own a PCB lab to make a professional looking PCB! Most important of all, it cost less for prototyping small quantity of boards.

@@fionasoon1 Yes JLCPCB are great. I received 200 of my charger boards for MY NICE EV yesterday. All for $68 or £64 to me here in the UK. Panelised 2 per 100mm x 100mm panel. I am looking forward to seeing more of your work. I hope you have an amazing day. Regards. Raymond.

The codes given is for the serial xbee transmitter and there is code for the receiver. The received serial signal from receiver xbee will be decoded and displayed by xctu. Do have a look at other youtube video for configuration for xctu to work with xbee receiver.

Error :There is no code for the receiver xbee

Thank you very much for your encouragement for a newbie like me. We prepare these videos for our postgraduate students to understand the operation of our machines.

@@fionasoon1 It looks to me that you are very proffesional and your videoing is great. Very well done. Keep doing what your doing. I will keep watching your videos. Have a wonderful day.

Yes, sir. Thanks.

Hi. The Raman spectroscope must be calibrated before use. This is to ensure that the machine is in good working condition. Or else, the results of other measurements obtained can be questionable.

@@fionasoon1 Ah. Yes I see now. At 69 brain not what it used to be lol. Thank you for taking the time to explain. You are awesome. Have a graet day.

Hahaha....safety first!

You need to install the correct library. The libraries are here. github.com/adafruit/Adafruit-ST7735-Library

@@fionasoon1 sir, thank you can you tell me the connections of 1.8 TFT Display and DHT11 sensor and Arduino Mega 2560 once again

@@devi-uu3ts The connections are all indicated in the sketch! Make sure you understand the codes for the I/O (input/output) pins.

@@fionasoon1 Thank you for replying me sir,as we are not using touch screen but in the code it shows a touch screen so still we can use the same code?

Estoy bien. Gracias. Al adquirir el CNC 2418, se incluye el CD del software.

Need to calibrate the height of the drill from the surface of the acrylic board and zero the ZYZ position in the GBRL control software.

It looks like my version is newer than yours, did you check the "Ignore error responses" checkbox for it to be able to read the lines?

Gbrl control 0.8, Inkscape 0.93. Use the old version of Gbrl control

Wow, I watched your video too. Very inspiring! All parts are in Fiona Soon 's video list. Type Fiona Soon in search box. Then, you will see part one.

Ah yes! I see now. My bad! Very interesting channel, not the usual stuff.

Hello, Muhammad. Please google to find out the basic theory of step down transformer and scr voltage regulator. They are structurally different and operate differently. If you read the specification of 2DM860, you can supply the stepper motor driver with DC40V or typical DC80V. ( 2DM860 2phase NEMA23 NEMA34 stepper motor driver 32bit DSP DC30-80V 1.8-7.0A).
