I came across this today and I thought it might be an incredibly powerful tool. So I was curious to see if anybody in this community has used it yet?

So I was shopping with my wife today and I said "oh let's see if my membership helps out." So we went and added the same item to each of our carts, and to our surprise, the total was the same! So what is it exactly that I'm paying for in this membership if the items "original price" is higher for me than it is for regular shoppers?

Greetings again! Yesterday I posted the schematic for this circuit, and today I have routed it as a 2 layer PCB. The intent of this board is for it to be a playground to build autonomous LED animations with the LP5812 ICs from TI, which seem pretty neat.

I'm hoping to get feedback on this design and sanity checks to make sure I haven't missed something when routing this out. I couldn't figure out how to upload multiple photos, so I'll add some more views in the comments. Cheers!

If you're interested in the KiCad files or other related things, I've got it on GitHub.

Greetings! I've been throwing this schematic together as I want to experiment with the TI LP5812 IC which is an i2c controlled autonomous matrix LED driver. I am a novice when it comes to electronics so I'm looking to see if I've missed anything in this demo board schematic.

The intended purpose of this circuit will be to provide a playground to experiment with different lighting patterns by allowing the user to interact with two of these LP5812 ICs over i2c as each can only drive 4 RGB leds each.

My main points of concern: Making sure that I haven't missed anything critical in the rather dense TI datasheet https://www.ti.com/lit/ds/symlink/lp5812.pdf?ts=1710689049125 as well as making sure that my schematic makes sense.

I chose not to include i2c pullups on this dev board as I felt that was best left for the host to configure, but I'm happy to learn. Thank you!

I hope this doesn't mean they are on the slippery slope of selling user data, thoughts?

Every time I unlock steel I feel like I get stuck. I have spaced out and I love it but I'm usually stuck to my first two planetoids because I hate the way I built my base but I don't have enough resources or physical space to rebuild everything before I can start doing more rocketry stuff. Any advice?
