Hi, I know this video is a little old, but would you mind sharing links for these components? New to electrical wiring and doing a senior college capstone robotics project and would like to avoid soldering. (links for switch, short circuit cutoff, connectors for switch) Thank you and your videos have been very informative!
i dont know if im a bit too late with my question on this video. but i designed the layout of my flightcontroller and have 10 pinouts for servos. 6 servos, 4 bldcs (with external esc). so i need to effectively power 6 servos at 3Amps stall current. I know i will not use them at max so they will never use 3amps from all the servos at the same times and probably never 3 amps at all. it would make 18amps stall current for 6 servos at 5 V = 90Watts. im not sure if i can place this directly on my pcb and if i have to use an external power supply for it. its a bit hard for me to understand. do you have literature recommendations for me to learn more about buck down regulators? sorry this question itself is a bit hard to ask for me because i am a mechanical engineer not a electrical engineer but im well capable to learn.
Hi Josh, I am curious what kind of connectors you are using that plug into the terminal strips joining two wires. Are those just two wires crimped into the same connector? i bought the same terminal strips, so curious to know the details.
Thanks! I am hoping to do a video on integrating IMUs at some point, but probably not as part of this build, since the encoder feedback and lidar SLAM will be sufficient for localisation on this robot. I'd really like to do a project that fuses an IMU with lidar or RGBD camera data (e.g. github.com/TixiaoShan/LIO-SAM ).
Great question. Firstly the battery is much higher than 6A - check out my notes on the "C" rating (I think in the previous video). You want the fuse rating to be higher than what you expect the load to be, but less than what will damage your wiring and power supply. What makes it tricky is that some loads (e.g. motors) can spike very high and wiring and supply can often sustain a short high spike, so the time the fuse takes to blow can also be relevant.
Hi, I'm really enjoying your ros guide videos. Could you show or advice some solutions to have non-removable onboard batter with charging port. I'm working on home survilliance robot-assistant
Hi, I don't believe the Pi has a built-in regulator (apart from the 3.3V one). Earlier models had a polyfuse on the USB line which is probably what you are thinking of, but the Pi 4 does not have this so powering over the pins is the same as over USB :)
watching this brought back memories of my undergrad lab sessions. Great video Josh.

What gauge wires are you using? They look like different sizes..
Great video as usual 😀
Thanks :D

Hi Josh,

I am mostly using ferrules/boot laces crimps :)
Why do so many projects use arduino connected to pi and use something like rosserial or microros instead of just using the pi and its serial ports?
What are the things you put on the wires after cutting them?
These are called ferrules or sometimes bootlaces
Hey there, which blog post details the wiring of the robot
Interested to see how you connect and interface with motors, sensors and other things. I assume you are going to use an accelerometer (MPU6050)?

Do you have to use VDC rated switches or VAC will also works well?
It is quite hard to get VDC switches in my area.
Hi sir, how do we choose the correct fuse value? for example, you used a 10A fuse for the 12.6V 6A Li Po battery.
Great question. Firstly the battery is much higher than 6A - check out my notes on the "C" rating (I think in the previous video).

Great video! What kind of crimp connectors are you using in the montage?

Could please the switch name or switch product serial Name/ID?
How many Amp of the terminal strp?
What is thick of the wire???
Perfect video! Thank you!
Thanks
Thank you for very good tutorial ~

Cool..
dont power the rpi that way, I am pretty sure you are bypassing the built in vreg
