Hi, my 3d viewer is not showing draw filled zones even if my pcb editor is showing. I am working on an MP3 player and ya it won't help in performance I know but its better to visualise with 3d viewer before ordering the pcb. Please help if you know how to fix it. Thank you
Hi, this is my 2nd gate attempt and last time I scored 38 marks in gate ee but I almost completely skipped maths and focused on core subjects. Now I am targeting for better score and need to prepare for maths and need help to know which series is good to cover subject. I am trying Ankit Goyal sir's 18 lecture crash course but it's going way above my head and I think i don't have time to finish a 60 lecture series as I only finished networks till now. Any suggestions ? Please.
Making an mp3 player with esp32s3 and pcm5102a DAC and TS482IDT amplifier for 3.5mm earphone jack.. i want the reviews on the audio part. Thank you.
If everything goes perfect I'll finish a have an esp32 audio board for playing music or use as Synth for piano or stuff if worked well.
First time playing with an azarbaijan guy.
Duno Why people even do this lol.
Hi I am working on a battery powered project and needs a BMS thought to use tp4056, dw01, 8205. I thought to have a general design so I can later use the same design in my other projects too if this works well. One question I have, i tried to pack everything close to save space but the tp4056 gets hot during charging so will it cause issue with overheating with this arrangement or shall I keep it away and give some space? I also thought to put an 18650 battery holder exactly below it, so confused with heating problem. Please let me know if you have any suggestions on the pcb.
Hi i brought PW Parakram batch at 9k but now seeing their timetable I feel like it's taking too long to cover topics. I already had 472 score, 38 marks in gate ee 2026 and wanted to improve my rank, and now thinking to get into vijay which is actually cheaper and more of rank improvement batch instead of teach everything from zero. Is it possible? Do PW accept such request? Is anyone in the vijay batch? Please.🙏 Or anyone who can suggest what to do . Please 🛐
My 4th year just finished couldn't get any job and I decided to give 1 year for gate preparation.
Thank you
I made a module on kicad for battery charging discharging buckboost and protections.
Texas ins BQ24074 for battery management, Texas ins TPS63020 for buckboost for 3v3 out, and DW01 , FS8205A (used in 1S 18650 protection modules) for over discharge protection. I wanted a charging discharging circuit to use in my other diy projects and did not want to use ready made modules like tp4056. It has an option for power saver or forced pwm mode and usbc and a compact 56*22mm size, and has all protections and Power Path Management. I wanted to know the mistakes in this. I attached links to images if these u find to be blure. Please let me know if you find any.
Thank you.
Hi I am making an esp32 dev board with 18650
battery. Wanted to make a cool desktop clock. I am using Ti BQ24074RGT for battery over charging protection, charging discharging and TPS63020 for buckboost to get 3v3 out. But now I got to know that BQ24074 don't do over discharge protection and relies on input signal to stop discharging. Now I don't know what to do with it, whether a new uc or add some more components like 1s 18650 protection or what. Please tell me. Also tell me about the pcb till now. Thank you. Happy to hear from you.
