it stoped my shitty car from leaking from the sun roof, minor miracle
I want to make a SBC powered vision model that is board powered, dual esc sized with a durable cheap camera.
Camera faces rear, Trained on video of approaching objects (cars riders dogs). It has one output, “object approaching” through a speaker.
Garmin has a radar system, It’s $300+, I bet it sucks. It doesn’t have AI.
I’ll give you a RPI5, camera, printed case if you speed run me through a fruitful training run of an open model.
You want Ai in your build,
you need AI in the machine.

If you were on a trampoline under a power line, if you jumped with double bounce assist from a friend, and touched an exposed section with only one hand you would be good, right?
Both hands would be a dead on some wires, but usually okay?
What about if you had an unusually long selfie stick and you touched the wires? (It’s not wet outside and you’re wearing shoes)
Okay, what if same selfie stick, holding while riding a PEV with a 26 rubber tire isolating you from ground?
I bet it’s significantly safer if I launch off a little kicker sand ramp and contact the lines strictly while in air. That seems like the most reasonable policy.

Pocket protectors and hard hats, I know you’re out there, in theory, and allegedly, definitely only in Minecraft, if one must touch a power line: which ones, what to wear or do with feet and ground, how many points of skin contact?
The “why” is irrelevant.

Two hands on the same wire doesn’t zap you because there isn’t a voltage difference on that one wire. Now reach across to another wire or touch ground somehow… BZZZZTPOP.

Hi, I NEED this to exist and am willing to pay for the development.
I asked chat gpt to help explain;
Creating a PCB (Printed Circuit Board) that produces a loud buzz when it detects a voltage under 60V involves several steps, including designing the circuit, selecting components, and laying out the PCB. Here’s a step-by-step guide to help you through the process:
1. Define the Requirements
- Voltage Detection Threshold: 60V
- Audible Indicator: Buzzer
- Power Supply: Determine if the circuit will have its own power source or derive power from the detected voltage.
2. Design the Circuit
You need a voltage detection circuit that triggers a buzzer when the voltage falls below 60V. One way to achieve this is by using a voltage comparator.
Key Components:
- Voltage Comparator: For example, the LM339 comparator.
- Voltage Divider: To scale down the input voltage to a level suitable for the comparator.
- Reference Voltage Source: A zener diode or a voltage regulator to provide a stable reference voltage.
- Buzzer: A suitable piezoelectric buzzer.
- Power Supply: A battery or regulated DC supply.
Schematic Overview:
- Voltage Divider: Scale down the 60V to a manageable level (e.g., 6V if using a 12V comparator).
- Comparator: Compare the scaled-down voltage with a reference voltage.
- Reference Voltage: Set to correspond to the scaled-down voltage of 60V.
- Output Stage: Drive the buzzer when the comparator output indicates a voltage drop below the threshold.
3. Design the Schematic
Using a PCB design tool like KiCad, Eagle, or Altium Designer, you can create the schematic.
Example Schematic:
- Voltage Divider: R1 and R2 to scale 60V down to 6V (assuming a 10:1 ratio).
- Comparator: LM339 with one input connected to the divided voltage and the other to the reference voltage.
- Reference Voltage: Zener diode or a precise voltage reference IC set to 6V.
- Buzzer Circuit: The output of the comparator can drive a transistor that powers the buzzer.
4. Select the Components
- Resistors: Calculate based on your voltage divider ratio.
- Comparator: LM339 or similar.
- Zener Diode/Voltage Reference: For the reference voltage.
- Transistor: To drive the buzzer, e.g., 2N2222.
- Buzzer: A piezoelectric buzzer that operates at your circuit’s voltage.
5. Lay Out the PCB
Using the PCB design tool, layout the components on the PCB. Ensure proper spacing and routing of traces to handle the input voltage.
6. Fabricate the PCB
Once the design is complete, you can use a PCB manufacturer to fabricate the PCB. Submit your design files (Gerber files) to the manufacturer.
7. Assemble the PCB
Solder the components onto the fabricated PCB.
Example Circuit Diagram
Here’s a simplified representation of the circuit:
Input Voltage (0-60V) --> Voltage Divider (R1, R2) --> Comparator (LM339)
--> Reference Voltage (Zener Diode)
--> Output (to Transistor)
--> Buzzer
Voltage Divider Calculation:
Assume:
- ( V_{in} = 60V )
- ( V_{ref} = 6V )
Using the voltage divider formula:
[ V_{out} = V_{in} \times \frac{R2}{R1 + R2} ]
Set ( V_{out} = 6V ), and solve for R1 and R2.
8. Testing
Test the assembled PCB with a variable power supply to ensure it correctly detects when the voltage drops below 60V and triggers the buzzer.
Example Bill of Materials (BOM):
- LM339 Comparator
- Resistors (for voltage divider and other purposes)
- Zener Diode (for reference voltage)
- NPN Transistor (e.g., 2N2222)
- Piezo Buzzer
- Capacitors (for decoupling, if needed)
This guide outlines the basic steps. Depending on your specific requirements and constraints, you may need to adjust the component values and design parameters.

What voltage is it and will you be protected with shoes?
I can do this in redstone.

Power lines vary in voltages (37 kV to 765 kV AC) along with amperage due to connections and demand but figures I’m seeing put it between 50 mA and 8 A @ 37 kV (1,850 W - 296 kW)
So I’m gonna lock in my answer with no.

This can be done with a tiny arduino running on VESC 5v, a piezo buzzer, and a voltage divider. Total cost ~15 buckerinos. The code would be
Void loop {
If(analogRead(divderPin) <= thresholdVal) {
digitalWrite(buzzPin, HIGH);
}
Else {
digitalWrite(buzzPin, LOW);
}
}
You could get fancy with different buzz patterns depending on voltage level if you wanted, too.

I have a couple of small 12v regulators with 100v DC input i can send you, I’ve got no use for 'em
Because it popped up and is relevant… This is what it looks like when a crackhead tries to cut a live 7.6kV line:
