I did some work on old lighting desks that were laced with CD4066 for scene select routing for the old 15vdc dimmer controls, and built a foot peddle add on for a guitar amp to select different pots into the overdrive gain section. Great device for its time.
Warning: those breadboard power supplies DON'T fit in protoboards. All the protoboards I've found move the power rails in closer together than on breadboards, so anything like this that assumes a particular spacing between the power rails won't fit. Also, they're center-pin-positive, FYI, on the input barrel jack.
I built a laser harp a few weeks ago! Different kit but still. It's a fun kit and trinket to mess with. Aligning the laser to the sensor and getting the mount that holds the lasers somewhat square was annoying.
Those chips could be fun to play with. Nice pens, useful too. I hope you have better luck than I did with my Laser Harp. I couldn't get it to work at all. :( I have so many of those Breadboard PSU's LOL.
Nice tip for power protection on those breadboard power supplies - it's the sort of thing I'd like to see from the manufacturers. Heck, maybe now someone's given them the idea .... I'm looking forward to the kit build.
I need to get a set of those markers. They seem like they'd be really handy in the shop. I vote sooner rather than later on the harp...and thanks for the bread board power adapter tip...I didn't know about the fail short.
@@GnuReligion I actually wondered this as well. I use Milwaukee markers for construction all the time but they don't make a silver or white one that I have seen
The 4066 might be useful for USB switching between two computers. hooking a mouse to in for A/B and a keyboard for C/D and a small amount of wiring, two DPDT switches and power shared from the computers to power the switch. I found it easier to find DPDT and not 4PDT switches. just a thought as data lines would need to be switched and not the power. I previously looked in to them for making my own KVM switch and found an analog printer switch box that worked better for my purpose many years ago and since been relegated to the recycling pile.
@@pileofstuff Yes, I have some of these chips also, and wondered of their use case. Audio? No, KVM. Still might try an MCU that switches between FM and Blu-tooth.
I think it is worth to build yourself a additional "crow bar" circuit, to protect your project from overvoltage.. Or maybe it is possible to solder a bigger Regulator on the board. Like a 7805. They are way more forgiving than the AMS 1117-x.
Yeah, the LM78xx series are a lot harder to kill. They've been my go-to for a long time. There's not a lot of room on these little boards for those, though.
Thank you!! A fun mailbag Monday as always. Picked up some markers like those you bought ... they're useful and work great. Question regarding the breadboard power supply. Do you have any more info/specs on the NTC fuse? Cheers ...
@ 8:01 "... the third thing in ..." is a kit. Except it came after the 10 chips, the USB cable, and the long tip markers, so... actually the fourth thing? 🤔
Can you show your office storage of all components? I would like to see your organization of components. I assume your office is in home to keep dry (not in a separate shop building). Moisture in winter here is very moist, I cannot afford to heat shop daily. I use spare bedroom as tech office. Ineed to start collection of parts.
The name of the channel describes my storage and organization method... Here's what it looked like a few years ago: th-cam.com/video/8kMI0NBjrNw/w-d-xo.html
It's a time honoured method, but not one I have used. Using optical sensors allows me to see if a part of the track has an unpowered car. And works even when the trains are not in motion.
I have one of those usb-c cables, mines much more accurate, .1-.5 deviancy in my testing, I use it often, it's pretty handy to see what's actually pulling power and how much, for example a handheld device won't display when power is pressed.. is it actually dead or is it a display issue?
Just a thought: if you flash pages with tracking numbers, it could make masking your address on the envelopes less effective (depending on where you had the package delivered and how much info the carriers share on the tracking websites).
I'm learning about electronics and currently exploring audio switching. Recently, I learned about CD4052 which has an additional negative power input, this led me to consider building a negative rail. However, I'm unsure about the implications of shifting the audio above 0V for a CD4066, so I decided to explore the CD4052 as an alternative. Will be good to see your results :)

Excellent am looking forward to seeing Jean-Michel “Pileofstuff”Jarre build and play the laser harp!!
Monday mailbag I missed it so watching on a Tuesday 🙂
Thanks for the video, going to order some of those pens, I think they'll be a good addition to my shop.
Now you can carry on harping on about the beer now with a bit more of a tune. 🙂
Good mix! Interesting harp, looking forward to the build. 👍😀
The long tip markers are of interest, and the breadboard power supply, which I do not have.

The worst part is the blow up.

Nice. Those charging cables for give off just enough light to find it in the dark.
Looking forward to the laser harp concert!

Now, the thing is ... does that white marker do well on common Black ABS?

A homemade KVM might be an interesting project.
@@pileofstuff Hey now, a KVM would be an interesting project, might make a good video.

A supercomputer could not protect you from the blue smoke forthcoming from these power supplies.
The long nib is so you can use it to panel decorate models aka Gunpla.

IIRC, it was similar to these: www.ebay.ca/itm/181623450694
4066 is used in Trash 80 Color Computer.

@@pileofstuff No point. Confess: you are a hoarder. The more you organize, the more you will buy to defeat your organization schemes. DO NOT DENY!
Have you tried using inline current sensors as track detection?
I always wondered how well they work.
It's a time honoured method, but not one I have used.
Using optical sensors allows me to see if a part of the track has an unpowered car. And works even when the trains are not in motion.
I have one of those usb-c cables, mines much more accurate, .1-.5 deviancy in my testing, I use it often, it's pretty handy to see what's actually pulling power and how much, for example a handheld device won't display when power is pressed.. is it actually dead or is it a display issue?
Need to electronically negotiate the HV transfer ... like a big iPad.
Just a thought: if you flash pages with tracking numbers, it could make masking your address on the envelopes less effective (depending on where you had the package delivered and how much info the carriers share on the tracking websites).
Given that I can't even find the items in my own purchase history by searching for the "tracking" numbers, I don't think there is a lot of risk.
@@pileofstuff you do you.
Luckily for you Canada post doesn't disclose the exact coordinates on a map when a parcel is delivered, as royal mail does.

Interesting ... am unsure if the 4066 goes below 0.
A laser harp so we can all pretend to be Jean Michael Jarre!
I expect mine will be more jarring than Jarre
Oh ... so cool! Glad you turned me on to Jarre / Oxygene. Most synthetic. I am going full Tubular Bells on this Jarre person.
I was wondering what is the value of your resettable fuse
I wonder too. Keep blowing the regulators, and despite the fuses, keep blowing them.
How long ship delay now?
Between 3 and 7 weeks on this batch of stuff.
I ordered the same pen same color some days ago 😅
