HEY YOU ABOUT TO POST SOMETHING STUPID:
Yes, I know my hands are large/fat. It’s because of a heart condition I suffer from called Congestive Heart Failure. Here’s a link to some information about CHF: https://cle.clinic/2TdS2Ux
One of the symptoms is that it causes fluid retention, mostly in the hands, feet/ankles, and face..

I’m still watching, lol, but I wanted to say I’m sorry to hear about your aunt. My mom past away just over a year ago and my dad was not able to live by himself because of safety issues. I filled in until we found a home for him. Even if I lived in with him, he still find a way to hurt himself… now back to watching the video. =]
I'd love to have that board with normal power rails (like breadboards).
I know why you separate + and -, but it would be more standard.
Do you have the cad files available?
Great vid as always, keep 'em coming.
Is your solder holder/tip cleaner on thingaverse or other 3D printer site, looks quite handy!
Nice board, the 555 is just being a s*it!
Nice job. As for the wrong frequency you checked the capacitor value but not the resistors. That frequency looks more what you would get with a couple of 2k or 2.2k resistors.
Male pins for outputs, female for inputs
Are you still going to use cheap socket headers to plug things into? I still think you are going to have so many breaks, cracks, and replacements as well as other connection problems using that as your contact point to hold the components. You're better off making your little add on circuits on a pcb with smt parts with pins to stick in a regular breadboard. Most people will just have those circuits breadboarded already and build their new circuits next to it. I guess that's where you got this idea from. Yeah, go with the pcb module to stick on a breadboard.
These are great for what I do Paul, I'll have to order some of them…
I set up a 555 astable oscillator circuit with the values described in your video, and get
approx 5hz. You must be missing a connection somewhere. Can you provide the original
schematic and pcb files? We can help with troubleshooting.
For plugs and jacks, anything with power on it should be female, that way, that part is shielded against shorts to ground.
I think this is an excellent and useful project. I just finished placing an order for 5 boards. Thanks!
Nice board. The only thing you might want to add is a ground pin test point so you have something to easily connect the scope probe to.
Nice board. Female connectors prevent for accidental connections. However i like the clock pin to be different. Perhaps using colored female Dupont connectors?
Perhaps also a ground and 5V connector for test equipment?
Hey mate, they look nice and the IC's are fitting now, winner!
I downloaded your gerber files; I could not find any missing connections. There
should be a 10nf cap from pin 5 to ground for stability, but should not be a
major problem. At this point in time, I have no clue what could be wrong.
YOU MIGHT HAVE SOME SOLDER BRIDGES AROUND YOUR 555 TIMER. i DONT KNOW IF THAT WOULD DO IT?
Clock pin – put in two – a male and a female.
What does the clock do without a capacitor, or resistor? (yes, I'm thinking board capacitance. Maybe not likely, but possible.)
I don't know about PCBWay or maybe I can't use their web site but every time I select to buy these boards they want to charge me $60+ for 5 boards (not including postage). Sorry but that isn't 'cheap'.
I think you bridged two pins on the 555 when you soldered @ 8:11
If you update the board again, perhaps a silk screen label in front of the power switch to show if power is switched on or off. That way you can tell if connecting to the power supply will immediately send power to the board. Additionally, as others have suggested, add an easy way to connect a ground probe. Maybe add a surface pad near the edge to connect an alligator clip.
Incredible!
Males are always better than females 😁
Pin 5 (control) of the 555 seems to be floating (no connection shown on schematic in previous video). 10nF to ground.
Always fun to watch your videos. You're like the Bob Ross of electronics- talking through your work as you go. Great idea on the protoboard.
