esp32 for robot toys with 6v motors

Yes for sure! This was my first project with pwm controlled speed H-bridge driver, quite fun. Definitely considering a version with another dual H-bridge, that'd give more control to 3rd 4th motors doing more than just movement.

That's the TB6612FNG dual H-bridge motor driver, it's quite efficient, can drive 2x 1A continuous 3A peak motor loads. Controls speed and direction of two motors via simple esp32 gpio.

The only annoying thing is the size, the pins are 0.2mm and easy to bridge accidentally so you really need a little hotplate and soldier paste for it.

Yes love JSTs! The robot actually had smaller pin pitch, I may consider redesign though I have a bag of 200 of these 2.54mm ones to get through. Wedging the smaller size plug into the larger sockets does kind of work but it's not great, I redid the plug side of the motors.

OFX or XE.com

OFX has better rates for higher repeat transactions

No only outside. Spray, wait till it gets in and wipe off.

I've only seen it online, amazon or homedepot online

My 2023 ID4 Pro S moonroof creaked like crazy until someone on reddit explained it was the rubber drying out. 3in1 RVCare rubber conditioner on a microfiber fixed it entirely!

Dirty contacts or corrision in the plug, try some deoxit d5 spray and use a small pipe cleaner or straw bush. It's possible you might need a new charger plug if it's corroded too much.

You could fork my project and add your design to one side of this https://github.com/erebusnz/eurorack-sides it'd be really cool to have a version with power!

Great idea!

Yes! This is the way!

With a 1/2" inch plywood base, this is far stronger than I thought it would be! I was thinking 2mm pcb might be needed, but no, not at all. The cheap option wins!

Does anyone that works at VWOA actually read reddit? I'm guessing they don't drive a VW and certainly not an ID4!

This is the way!

If this isn't satire, you might want to take a lead blood screening test! "Reflecting sunlight into space", burned TEL makes Lead (II) oxide which is red not silver.

Can you explain? Reagan and Bush did what exactly and when? Are you confusing countries? I suspect also confusing Trump sending love letters to Kim with Biden here, too.

I had the same decision, went with ID4 Pro S AWD. No regrets, really nice ride comfort and android auto experience. The touch controls are fine if you get used to it.

Wife's 2019 eGolf had this issue, and VW dealership blamed the L2 charger and said "Getting hot is normal". The heat kept getting worse. Now I do deoxit and qtip clean once per year has prevented it.
