Why does PCB to blinky LED take so long? 🧑🏼‍🏭

[@NSKChaitanya]

Fantastic video capturing the steps of a board bring-up!! kudos.. However, I do have a question. Why use a USB connector and a battery directly? AFAIK, it is a standard process to perform the board bringup with a current limited PSU. Isnt it a much more controlled / reliable way of ensuring a current runaway does not happen?

[@sayanee]

Yes, yes yes!! Please use a current limiting power supply unit :) I have missed out on this very important step of the board bring-up process, so thanks for pointing it out! I'm still on the lookout for a good PSU for my home lab. Do you have a recommendation for a model that is decently priced?

Great info but my favorite part was your final thought: be kind and patient with yourself. So true here and in so many other endeavors.

super underrated channel, love the content and hope your channel continues to grow!

[@kerseyfabs]

You have fantastic content! Your methodology and presentation are just so clear! I'd love to collaborate with you on a future project.

[@sayanee]

Thanks for sharing about 3D printing and mechanical stuff, which I plan to learn soon as well :)

Loved the video and the ending message!!

[@khanshahzad77]

such a nice information thanks

[@bhargavmistry1274]

Nice one! Very informative!

[@roguesecurity]

Very informative video. Thanks for sharing. Which IC r u using for power management?

[@sayanee]

If by power management you mean, LDO I am using AP2112. Or if you mean LiPo charging, it's MCP7383. Feel free to refer to the schematic :) hutscape.com/oak/hardware/docs/schematic.pdf

[@roguesecurity]

@@sayanee Thanks for the reply. I wanted to know the IC for LiPo charging. Have you used TP4056? If yes, what's the difference/advantage of MCP7383?

[@sayanee]

@@roguesecurity Nope never used that chip. Seems like a couple of articles pointing to these 2 chips as indeed the common ones for Lion charging. 1. hackaday.io/project/169422-iot-ups/log/177680-battery-management 2. embedblog.eu/?p=123 If TP4056 works for you, just use it :) Unless there is a particular goal in mind to change the chip E.g. cost, other properties, etc.

@@sayanee thanks a lot

Nice content. Ages ago when I was forced to use "Tier 3" PCB makers, the first check was the one you did , check for short between Supply Rail and Ground. Then for a shorted board , I used to use a high current , low voltage (

[@sayanee]

Wow! Thanks for sharing. I'm sure even today there will be manufacturing errors, but generally, for a simple board, I'm guessing these error probabilities are reducing with better machinery and checks.

[@mumbaiverve2307]

@@sayanee Well they seem have gotten vanishingly small , at least in the board densities I operate at , (10mil spacing between tracks, types)
