• PCBX Sponsorship Ryan Scomazzon

  • Good news and bad news

  • Good news: Turns out they didn't ghost us, it just got sent to junk

  • Bad news: They are ops of deception and basically used this as a marketing campaign. Their offer for free services was only for the first order and everyone gets this as a new account promotion. They conveniently didn't mention this in their first email.

  • They mentioned something about offering a discount to us for long term cooperation? I sent an email to push for what we can get out of them but I think this is probably a dud

  • Back to looking for a JLC sponsorship, I can use some help with that.

• Comp/Eclipse sync

  • No eclipse sync

  • Comp sync tmrw night (Thursday) @ 8pm in E5-2103

    • LAST COMP SYNC OF THE TERM

12V to 24V Boost Groundside Converter - Electrical - WARG

• Tim Gu

• Asked about some requirements/constraints for this board, hoping to start doing some of the math once I

• Looking into options for buying one premade

• Read over some guidelines from Texas Instruments on working with boost convertorsDid some research on designing/working with boost convertors

• Getting started on calculations

  • Input current may be around 90-100A (very rough estimate)

  • How much current is too much (to the point where we can’t make this ourselves)?

• Looking into COTS options for buying one

  • There are some 12-24V 50A DC/DC convertors that seem promising at first glance, will dig deeper and document updates

• some ideas:

  • If we don’t charge 4 batteries at once the input current will probably be a lot lower

  • maybe use multiple boost convertors (like a multiphase buck)?

Water System Controller rev 2 - Electrical - WARG
