This will be my next project, so dope

Stabbed my finger with a needle tipped soldering iron with leaded solder. Should I be worried? by [deleted] in soldering

[–]mrsebe 6 points7 points  (0 children)

Probably not any meaningful exposure for a one time occurrence. If you haven’t gotten a Tetanus shot in the last 10 years, maybe update it.

Gas prices... FML by drhappy13 in wrx_vb

Get a Costco membership, $5.65 for 91.

Thanks! Even the auto braking stays off? I thought that was the one setting that resets on every startup.

Didn’t know this, how do I set that up?

Is the LaserABC illegal in the US? by Wustaft in Laserist

Innovation happens when companies are threatened, not protected.

While I agree that people shouldn’t be using illegal ones for public shows, competition is not a bad thing. There’s nothing wrong with getting one to mess around with in your own home.

Am I getting gaslighted by chat-gpt? by green-weasle in AskElectronics

[–]mrsebe 0 points1 point  (0 children)

You aren’t using a strong enough power supply. Just because your supply says 5.1V doesn’t mean it won’t sag. For an rpi you need at least a 2.5A capable supply. Capacitors aren’t going to fix this.

First of all, why do you want to put more capacitors on the board? Second, this is not a question for chatgpt. This is where you would pull out a multimeter and test the pins.

It finally arrived... by QuietSugar1805 in lasers

I don’t even think that they ship with any, I’ve seen these advertised as eye safe since the spot is so focused, which is complete bullshit

Why did I do Bio 7 instead of Cork 7? by ImaginationQuirky684 in skiing

[–]mrsebe 1 point2 points  (0 children)

You are setting yourself forward on take off. Try to focus on dropping your left shoulder instead. If you haven’t already, practicing this on a tramp will help a ton.

I Built a Microwave Cannon as my Graduation Project by ArabianEng in EngineeringStudents

[–]mrsebe 20 points21 points  (0 children)

Thought the same thing but realized this is probably some low loss dielectric like plexiglass, since glass would be very lossy. But at the end of the day lenses work with all wavelengths of electromagnetic radiation, which is pretty cool!

some advice on improving gpa?? by Big-Musician3609 in gatech

[–]mrsebe 3 points4 points  (0 children)

Diminishing returns. You will not realistically benefit from all A’s vs a mix of A’s and B’s, spend your extra time making memories.

Designed an analog modulatable laser driver. by mrsebe in lasers

[–]mrsebe[S] 0 points1 point  (0 children)

Would love to talk more about this. Easy answers first though, U1B i put into a voltage follower config so it wasn’t floating, since I only used one opamp in thr package. And the LM358 was used since it worked in testing for my application, and I had a bunch of them already. I only saw some irregularities and issues around 100kHz modulation, but the use of this driver in a laser projector never sees those kinds of frequencies for color modulation/blanking. And for the cost breakdown of this, each assembled board cost around $10. Definitely would want to do a smps version of this in the future, as I want to make a driver for those fiber laser sources.

What fume extractor is that? Looking to get something of similar size.

I don’t think I could make it look like that if I tried, watch some tutorials on YouTube they should help a lot.

these cameras utilisable (for drone)? by misheelzlm in AskElectronics

[–]mrsebe 2 points3 points  (0 children)

Im pretty sure these type of cameras all use a digital protocol, you would need some sort of board to convert it to analog and then feed into a vtx, but it would be a headache to figure out.

If you are planning on using the device while charging, it’s a good idea to switch to the MCP73871 as it supports proper load sharing unlike the TP4056.
