About LongTechnical » In this video i had show you Portable Voltmeter Ammeter Wattmeter with Rechargeable Battery Insite All of thing we need in there. Please check on description and do step by step you will get Portable Voltmeter Ammeter Wattmeter The firts we need to make PCB. I use eagle software for design shematic and PCB. After that i order the PCB by upload gerber file to JLCPCB.COM and after 2 day i reieved 10PCB high quality with only 2$. You can try like my by upload gerber file to JLCPCB.COM for get PCB online. Or you can make PCB by yourselft by download the PDF file at end of topic. look at some picture from my project, and check more video at my youtube channel https://www.youtube.com/channel/UC0dW_Q1nhPqbUQZvbeogOnQ/videos LCD metter.pdf LCD metter2.pdf
Introduction ---------------- Hi Friends, I am a newcomer. I try to make 750w DC 24V DC motor speed control. At my project i use TL494 ( ka7500) for control the motor, the current increase by 3 mosfet IRF75n75 ( IFR3205) you can use the biger mosfet for get big power. At this video i show you how to i make it. I don't have the big motor so i use 288W 24V 775 motor for test. You can see the result on my video. The circuit run very well. The total cost of the project is around $10 - $15. Step 1 Hardware Requirement You can see all of my project but i will show again Step 2 Make the PCB You can make the PCB use iron method. I have post the Shematic and PCB file. Please download bellow. Or you can order PCB online like me, i order PCB online from JLCPCB.COM. Their price is very low only 2$/10PCB with high quality. I order PCB from their lot of time. You can try. Look the PCB i had order, what do you think about that ? Step 3 Make the PCB The Schematic and layout file. you can download PDF file below and make it at home by yourself. Step 3 Finsh and Get Big Motor Controler I am a newcomer and this is the fist time i post on this forums. If i have any mistake please comment below i will try to fix in the next project. I want to share you all of thing i know. If you have any question for my project, please comment below i will help you.
