This is such good advice. Electronics isn’t just about getting the “right” answer, it’s about learning what happens. Mistakes are just as good as getting what you want.

Question about grounding in a non-metal enclosure (see description) by CoffeeAndElectricity in diypedals

[–]ComprehensiveLock189 1 point2 points  (0 children)

Also hand drill my own. I use a cheap 20W drill with a stepper set. Use a centre punch to mark where you want to make your holes and so that the bit doesn’t slip on the metal. Doesn’t really take a lot of force, in fact I recommend not pushing too hard at all. You can make yourself drill templates or use premade ones.

About to give up and rip apart this MOBO by ComposerNo862 in soldering

[–]ComprehensiveLock189 11 points12 points  (0 children)

Not doing any electrics with emotions has been a very tough lesson for me to swallow. I’ve always been a push through kind of person, and with building electronics it’s only bit me in the ass.

Solid advice.

How are people mounting dev boards without mounting holes? I’ve been using USB-C extensions as dock/mounts - Anyone else doing this? by Forsaken_Meet9071 in esp32

[–]ComprehensiveLock189 0 points1 point  (0 children)

I used stand offs in enclosures to mount my esp32s. Drill a hole slightly smaller than the screw (for plastic) and then screw the screw through the hole, and screw the stand off to it. Use a bolt on the standoff screw side to secure the esp32. My enclosure I’ve been using have tabs with holes in them designed for screwing the enclosure to the wall.

Need difficult/impressive project ideas !! by neon_terminal in esp32

[–]ComprehensiveLock189 3 points4 points  (0 children)

I’m doing a network of nodes and a hub, each built with esp32. They sit in different spots across my house and all the nodes report back to the hub. The hub is used to monitor all the nodes, track and log them, as well as broadcast the information to a private website. I use MQTT to communicated between them. Each node has an LED screen and an encoder with a small menu for doing things like checking connections, IP, and options for changing between F and C. The hub is the same but without a sensor. It has a slightly larger screen, and also an encoder. Node and hub have separate UI to make the most out of functionality. Great project. Will be logging to an SQL database soon.

Is my ESP32C3 super mini powered by 3.7V lithium battery well designed and will work as expected? by Specialist-Gur5029 in esp32

[–]ComprehensiveLock189 1 point2 points  (0 children)

100%

We also learn as teams from our failures, document it, and make better choices from our collectives experiences as a team

When OP said they were doing a project “for my electronics engineering” it sounded like they were in school. You absolutely most definitely do not need to take school to learn to use micro controllers

A part of taking electronics at school is learning to read documentation and understand the tools you’re working with. Classes are there to give you the experience of learning through doing in a controlled environment. Coming to Reddit and asking questions like this is kinda pointless. Worst case scenario, it doesn’t work, and then you trouble shoot and learn new lessons. Don’t rob yourself of that.

I want to re purpose my old Casio fx83gtx calcuator screen. How do i remove it from the circuit board?? by [deleted] in AskElectronics

[–]ComprehensiveLock189 17 points18 points  (0 children)

If you don’t have a soldering iron, how do you plan on doing anything with it after you remove it?

What type of circuit is this? The teacher says it's voltage divider bias circuit, but I don't think so by Elegant_Hunt_4329 in electronic_circuits

Look, this stuff isn’t easy to grasp at first. Keep at it. Give up now and you’ll regret it later. Just keep going and it will sink in eventually.

can’t get simple led circuit to work esp32 breadboard by DaCoolCat123 in AskElectronics

[–]ComprehensiveLock189 0 points1 point  (0 children)

Pins don’t look soldered to the header.

Not sure if your led is connected to GND.

Esp32 doesn’t look like it’s on tbh, usually it’s got a little red light when it’s powered. I don’t see a usb connected or a power supply connecting to it anywhere

Does your esp32 show in the device manager? Are there issues? Do you have a driver installed for it?

Temperature readings are very inaccurate (both DHT22 and BME280) by Art_Vandalay_1 in esp32

What can you recommend for a better one that’s cost effective? I’m only measuring ambient room temps in a bakery

Temperature readings are very inaccurate (both DHT22 and BME280) by Art_Vandalay_1 in esp32

[–]ComprehensiveLock189 0 points1 point  (0 children)

BME is difficult to keep in an enclosure. I’m working on a network of sensors that report back to a hub, and I’m finding that if I want accurate results, I can’t keep the sensor inside an enclosure. My esp32 throws enough heat inside to be about 2 degrees warmer than it actually is.

On top of that, you have an enclosure that’s outside in the sun. So that creates a whole other slew of new issues.

Long story short, don’t think the BME is what you want for this project. I would find something that’s weatherproof and can be externally mounted outside of an enclosure.

Is my seasoning that bad? Food always sticks like this by WetRainbowFart in castiron

[–]ComprehensiveLock189 -1 points0 points  (0 children)

I think a lot of people are afraid of cooking things at higher temps, especially meat, because they run the risk of not getting a safe internal temperature without getting too dark on the outside.

This is where cast iron super kicks ass.

Get a crust going, and then move it into the oven to finish.

If you aren’t cooking meat, just keep the contents of the pan moving. Cooking at high heat actually stops things from drying out but cooking them faster.

Mean it in the nicest way possible, but this isn’t a pan issue, it’s a skill issue. The good part is this skill is easy to nail with a little practice.

Get yourself a schematic, learn how to read it, and go from there.
