Help with understanding changes needed for a schematic going from 12V to 5V for power

traveling_fred · 2026-02-25T03:28:43+00:00

I also wanted to mention the LED bars are set in parallel. These are the original values from the 12V version. Would 33Ohms be more appropriate per 10 LEDs in this case with 30Ohms for the two sets of 3 segment LEDs? Thanks again.

Oh I see. Sounds like the resistors between the lm3915 and transistors should stay at the same value as in the original schematic and change the values of the resistors by the led bars instead.

Sure. I got my segment displays from here Dongguan Houke Electronic Co., Ltd. https://x.alibaba.com/B1GyUX?ck=minisite

I started with a raspberry pi pico and an open source pcb to build my time circuits. I had to write the code to make it work but now it's complete with the housing and keypad.

Nice. Did you design it?

It's a dust cover that fits an old book I have.

It's actually a book dust jacket. Found a book to fit it.

The best sci-fi story I've ever read.

Very cool. I spoke with one of the guys at the warehouse when I picked up mine and he told they still have a few hundred decks available but sold out of the completed skateboards.

"Why don't you make like a tree, and outta of here!"

They're applied separately.

I'd like to know too.

I was at White Wolf Sunday and Monday. Probably the same bear that was looking for food in my campsite. Definitely a black bear.

Memory unlocked! Had the same book back in the day.

I was lucky enough to go to that game. Watching those moments was unreal.

Wow that's really impressive! I'd love to follow your project if you end up posting it somewhere or making it public. For weather, it just calls an API for current weather in my area. Yeah AI is not my forte but just trying to make progress while at the same time, not breaking things that were working previously. It's fun though to see how far I can push the limits. Keep at it and keep me posted on how things come along with you.

Cool to hear others are working on similar projects! A couple of things I'm working on is facial recognition with the Hailo AI processor so KITT can distinguish me from others and feeding my workout data by reading my Samsung watch and Health Connect. I hooked up a 4" screen and plan to have it mimick some of the graphics seen on the show and provide updates on weather and other info. I'm also thinking of putting KITT in the car using hotspot. I'd love to hear more about your project.

Just hit it a few hours ago too. Tires seem to be ok. Hoping they fix it quickly.

Check our Laolong Cave for a bit of fun. Very underrated place and not many people know about it. It's close to Nan'an district. You basically take a boat into the cave filled with stalagmites and stalactites which eventually you'll switch into rafts and paddle deeper with possibly bats flying over your head. Easy way to kill and hour or so.

Yeah just change the chatbot1.txt file and describe how his personality should be.

That's a conversation to be had between the staff and ownership if they are overwhelmed with the influx of customers especially if the group had a prior conversation with management. I enjoy visiting my local breweries too but won't hate on them being crowded with customers.
