Hey, great job. Question: Could you do more overlaps on the laser path so that your etched area doesn't have the thin traces in the middle ?

Im trying to make a pressure triggered lightswitch with these, it's lighting up with or without pressure, do I need a zener?

Would this relay work for a replacing a switch for gas fireplace?

how to wire it ??? so you glue the wires on ? connect power source and a loud buzzer ? waste of time video !

If you glue the disc down, will this make it louder without the use of a shroud around it?

Thanks for sharing.

Maybe it's just me but this doesn't really show how to wire up anything at all... you're explaining how it works but you're not actually showing where to connect it, I don't know anything about a breadboard I just want to know how to solder it up physically from the power source to the button not inserting pins in a euchre board lol

i am looking to mod a VCR's buttons to switches

Thank goodness these videos remain available years after first posting. It's 2024 and this is the best video about wiring up the Syepper Motor. I'm using a newer version, TMC2209, but the info your provided seems to apply quite well to the newer version. So, thank you!!!

This is just wonderful and it only took me 7 years to find it. 😐 I use a Raspberry PI though, which does not have an analog connector. 😐 I WISH someone would provide a step by step guide as good as this for Raspberry PI using an MCP3008 analog to digital converter. 😐 I love this stuff but finding examples and explanations ....its a struggle...for real. 😐 Kodos on this wonderful walk through. You are a hero to many... 🙂

Don't use a saw on the pcb's use a cutter mounted to a bench ffs. No wonder you have wonkey uneaven boards

Will Lipo 4.2v kill 3.3v D1 mini?

You can regenerate the etching solution by adding H2O2 again.

Can i use arduino mega as well?

Looks like I have something else to try on my laser. I started with a Diode in 2019 and then 3 months later moved to a K40...I did upgrade to a Mini-GRBL so I could use Lightburn. Then a year after that, I moved to a OmTech AF2435-80w. I never knew Lasers could do this. Where did you get your copper sheet?

Extremely easy to follow. Thanks for the tutorial

Why you don't engrave Black color filled area. I've checked and it works better. It's even possible engrave top layer of etched pcb

wouldn't it short the output if the button is pressed and the output is connected to low at the same time

You can use direct port manipulation to make sound or sense with many piezos at once.

I had the same idea but instead of wifi I was thinking in use Bluetooth zigbee or RF433mhz due power consumption of the battery, did the battery last long ? planing to integrate with home assistant

OL = out of limit. No continuity. Infinity.

The resistance measurement setting on the potentiometer? That’s an error I get it, but you left it in the video. This stuff can be confusing enough without you calling an ohm meter a potentiometer.

4:43 does a higher resistor make it more sensitive?

How could you create a wire cradle so you dont need the breakout board? Think a breadboard with sewing pins would work

what power supply u used?

Can I weld wires to these buttons to use them for any application? (One hot wire 12v & one ground) just like those normal push buttons in cars

A VDO should use an input and output capacitor in order to stabilize the Vin and Vout. You are soldering the 2 capacitors always to the same VDO pins (ground and Vout). Honeslty I don't understand what you are doing.

0:22 Where can i buy the 4.7k transistor?

Buttons ARE switches, SPST

Nice! The piece of info I was looking for is: Is the polarity of each coil important? My 1st stepper is not rotating and wondering if I’m opposing coil fields?

not plug and play.

THANK YOU

Why don’t you drill the pad holes with the laser. A fiberglass pcb isn’t all that thick.

Could you please inform me about the laser module you are utilizing? I have a 1000mW module, but it seems unable to burn through the layer of splay color.

Thank you so much. This was so helpful and not to long either you are truly amazing. I really hope you can keep making these videos. I am teaching myself circuits so any help I can get is truly amazing. Thanks.

Can you suggest some other option to clean the laser burnt paint from the PCB? IPA cannot remove all the debris and leaves a black outline around the traces.

Photo switch. No solder mask? Nice technique.

Yes safe hand gloves

Don't you have a image or drawing for connection diagram ? I see that you made an adapter where is a ceramic capacitor .

what arduino did you use

Is the matt black paint any special formula or just any old paint will do?

draw the work can makes the diffenrence

meh, now you just have a constant drain from the power source via your "pull down" resistors.

will this work on 12 volt system line on a truck to dome light with a horn. when doors on the horn will go off.

So you’re saying it’s like redstone?

People can see what side has legs coming out and obviously what side doesn't and you ?

Is the circuit board a arduino trinket?

To remove the lasered paint, I had much better results using Lestoil (a household cleaner with petroleum distillates) & household ammonia instead of isopropyl alcohol (rubbing alcohol). I first rub Lestoil on the board (undiluted) and gently rub MOST of the unwanted paint off. Then I use another clean cotton swap or brush to apply more Lestoil over the board (don't wipe off the Lestoil), then rub straight ammonia over the board to remove the rest of the paint. The Lestoil and ammonia combination (mixture) will remove the rest of the lasered paint. I use Rustoleum Matte black Custom Shop spray paint. I'm able to get a resolution of .1 mm (razor sharp)! Had no issues of accidentally removing UNLASERED paint, like I had with alcohol. I use a 5 watt laser set at 80% power @ 750mm/sec (travel time). After etching, you can use denatured alcohol or acetone to remove the paint, denatured alcohol being less volatile.

The respirator comes for free, while ingredients for solution is $9, yep.
