Nice work Felix and easy to follow. I'm going to add a switch directly to the pump and wire the active internally. You have a sweet and gentle way of sharing your knowledge. Thank you

What is the voltage limition? 0 to ?

Yeah didnt help, anyone can find the damn thing but im looking for where to plug it in

*Watched this again today after talking to chatgpt about photo emulsion solder stencil making. This video is great. Among the best electronics tutorials on this platform. Thanks again!*

Hi there! Is this available as open source or for sale? Please let me know. Thanks in advance!

Absolutely horrific showing from the CN paste, probably extremely toxic too, that flux looks disgusting.

What is the maximum input voltage?

thank you very much . can you use a shelly uni inside the door lock to control the lock ? it has 2 dry contact and it's powered by 12v.

Great idea, hope to test it soon.

Awesome! Looks great. Just ordered one and can't wait to try it out.

One more question :). Is there an instruction to set up the HC06 BT logger? It is definitely not straightforward.

Huh smart. tho I'm scared of acids!!

very nice procedure!

Why on earth is what the rest of the industry calls paste mask layer called a "cream" layer? Is that an Eagle thing?

don't you need to cover the back of board as well to prevent the etchant from eating away the surface?

Very nice

Nice 👍👍

ok just take my $7

For the next revision i would narrow down the oled header holes to 0.8-0.85mm such that the shield plugs in directly without any socket, it will look cooler.

I was wondering initially whether this method is suitable for spray lettering/labeling stencils but I don't think so. All the rectangles of your project turned rounded.

Thank you! Did the same thing when replacing rear struts.

Amazing result for amazing job for cheap solution !!!!! Congratulations!

Have you made the PCB for FM / VHF / UHF frequencies ?

Saw now. Nicely done. Thanks!

Is it theoretically possible that I have fried my RFM69 even with an antenna? I had “radio init SUCCESS” for a while but after I tried to transmit my own data it became “radio init FAIL”. The 2nd board I tested with worked just fine so I know it’s definitely not a software issue

so glad this still exists! I forgot how this was set up for my Nin10do kit I built in 2016/2017.

I wonder if sodium hydroxide works as well...

If you’re trying to pronounce the name imagine a sledgehammer but make the sledge part sound like age and you’ve got the correct pronunciation Schlage hammer!

The fact that people can’t pronounce Schlage cracks me up every time. If you know anything about locks you should know how to pronounce the name L O L. It’s S L A AGE. It rhymes with age.

Hi, you do not cover reverse side from etching?

Nice!

Andreas Spiess mentions you in his videos. I hope to learn as much with your videos as I do with his.

Nice, could 60W laser just cut in aluminium soda can for perfect finish?

I was thinking about using a photoresistor to detect if mailbox was opened. When exposed to light there is less resistance and that perhaps in some way could let some current through , enough to wake up the esp32 ? I was going to place the unit in teh back of the mail box towards the top.

Why are you toe nailing shit?

Wondering why do some RFM69 modules come with two large PCB pads? What is their purpose?

Looking for an instruction on the firmware. I use Arduino regularly but it doesn't recognize the Current Ranger. Really all I want to do is disable auto power down.

Excellent video. I have a PCB antenna that is broken and I wanted to see if there was a solution. How can I send you the image? Greetings from Peru.

Nice idea will try it out i have such a pump

Dude this guy is fast as fuck

wait I still dnt get how this works.. the toner, you mean the printer ink? The printers ink will be enough to act as a barrier for the etching? I dont get how this is possible without cutting out the small holes..

Is it possible to use dry film and ferric chloride? Is it possible to just print a negative on an acetate overhead sheet, laminate the dry film on the aluminum, develope the result, and then etch with ferric chloride or your phosphoric acid/peroxide mix? I figure if it would work, it would probably improve the definition for very small solder lands.

Thank you!

We are actually planning to buy it. What is the max range of current it can take? as we are using LORA and its peak current is 140mA. We want to study sleep currents and battery life calculation with help of this device.

Can I use the I2C channel to read the measurement data with a microcontroller?

Nice info, keep it up,thanks for sharing :)

What is a PCB?

не плохо, но, по совокупности затрат эта технология , приближается к удалению гланд (полипов в горле) газовым резаком (автогеном) через жопу (через анальное отверстие)

very good video
