10:00 Diffrent colors for difrent materials. Black is graphite for paper, wood, drywall etc. Yellow is more of a grease pencil for metals. And red I do not use but when I recall correctly was for glass.
Stick a cotton swab (might need to cut one end off) in the pencil and you can extend the reach some or add strength when scrubbing stubborn flux residue.
As your experiments with the Flying Desk Cam demonstrated, sometimes you have to work with that organic cellulose foam stuff when doing an electronics-oriented project.
That BNC connector will be useful. I don't know if I mentioned it before, but you can get small solenoids like those with a latch similar to what you find on cupboards and lock boxes.
Ive been using a RP2040W pico to wirelessly control a Sculpfun iCube laser engraver 🙂 , The wifi version is quite interesting combined with a few buttons and oled.
1:25 .. If the esteemed viewer would kindly focus his or her attention to the bottom left corner of the screen :D .. 4 bucks is the official price recommendation on the pi homepage ;) nice ale ! thanks for the mailbag !
@@pileofstuff I like to use it a little from time to time, Gary Kildall really had a good thing in that operating system. How things would have been different had he (and Digital Research, of course) and IBM partnered for the original PC...
Buying the Pico from most reputable vendors (adafruit, sparkfun, canakit) goes for $4 US or ~ 5.56 canadian. So far I haven't seen it any cheaper on other sites. Not a big deal but just worth noting.
Hope the BNC-banana adapter last a bit longer than mine cheap ones did. They develope poor contact in the grounding on the BNC, the twisty part, after a few times used.
Properly built BNC connectors can be used without the "twisty part" as the outer shell is supposed to be the ground but yes, good quality adaptors are hard to find on Ali and Ebay.
@@pileofstuff Typical, I probably pressed stop right at that moment :0) I did find that the coloured fillings for these were quite soft, but otherwise, nice pencils.
Haven't watched the video fully just yet, but the dupont jumper cables may be copper plated iron wire, so try with a magnet to see if it is iron. I once got a few wires wich were iron and has quite a high resistance for just 10 cm.
Note that the prongs aren't square, but a flat blade bent into a U shape. The last few batches that I bought were too wide in the U to fit into breadboard, and the cut surfaces had so many burrs that they literally ground away the plating on the breadboard contacts. I prefer the round pin versions, but unfortunately they usually have the thinnest and most nasty cables that don't last long. Still trying to find decent 28-26 AWG silicon with proper pins on them, so I don't have to make my own 😢
Most of them are some sort of ferrous metal with a plated coating. At the power levels most people use on breadboards, it's not enough added resistance to be problematic. And, as an added bonus, I have used magnets to connect jumpers to batteries temporarily!
Get the DuPont cables with the alligator clips and you'll never have enough, but they make lousy connections that come apart eventually with those bent metal prongs. I've made coupe foot long extensions with them but now will have to check the resistance compared to the homemade ones I've been making with copper wire. But for breadboard stuff It won't cause any issues, maybe give some inaccurate power consumption measurements, so it a good to know anyway.
I choose whatever strikes my fancy at the time. Might be inspired by someone else's project, or by some plan I have at the time, or just "hey, that's cool".
i like looking you mail box videos, my mail come only now ewery month CNC machine parts and boards, i build my son own cnc machine him want make woodwork more stuff.
12:53.. You have clicked on a color that IS NOT in stock (dotted square around product). That is why they don't ship to your location. If you click on a product color that IS Stocked (solid square around product) they will ship to your location.
