6 episodes already, time flys. Today we have a smd practice board. More micro soldering fun coming at you! Can you count how many times I say solder or soldering? Winner gets a no prize.
For those people who I dont force to watch my content, and those who I do thanks for watching.. I know my audio skills are lacking but I really do hope to improve them. And again sorry for my voice I can't help it. blame my parents.
Nice channel. welcome to the wonderful world of TH-cam! I wish you well.
As for plumbing references to describe electrical parts, resistors are flow restrictors (not valves valves can be adjusted), potentiometers are valves, diodes are backflow preventers, capacitors are pressure tanks. triods are electrically controlled valves (the transistor being the most widely used version since it largely replace the vacuum tube in the 70s)
As for capacitors: a cap is a pressure tank - water (electrons) flows into the tank until its full and the pressure (voltage) in the tank matches the rest of the system; then that stored water (elections) get released when the pressure (voltage) outside of the tank (capacitor) decreases. As it discharges its water (electrons), the pressure (voltage) in the tank decreases.
Most pressure tanks cannot be connected in series as the aren't built that way, but if you did build one that way, it would work the same way as a cap does. it would prevent the flow of water through the tank in a single direction (it would simply take in water until full), but if the direction of the water oscillated, then the water would seem to flow through the tank just as A/C current does through a capacitor. Electrons move way, way faster than water molecules, so the frequencies a water based system could operate at are far, far less than those for electrons, but the analogy is pretty good.
As with all plumbing analogies, there are some differences from actual performance, but they're fairly close from a high level.
As for it being "super easy, barely an inconvenience", I was not familiar with "Pitch Guy", so I get no points, but I did learn a new catch phrase or 2 I'll have to remember when "things are tight"
As for the translation issue, I'm sure you're missing the implication from the chinese - you simply have not been learning the "proper" language you need to use products from "the great China". Resistance is Futile - You Will be Assimilated.
Again, nice channel. good luck!
Thanks for the input! always looking to learn. I'm an HVAC Tech by trade, so while im very familiar with electricity and plumbing all this "low voltage" stuff is a learning experience. The lowest voltage we play with is 24vac.
I wanted to learn about and tinker with electronics so I could also repair the control boards in my equipment. The prices of those thing are out of this world lately. If I could spend 20 minutes replacing a 10 cent resistor instead of buying a $1500.00 "board " better me making a few shekels then my corporate overlords at Carrier and Trane .
I kinda enjoy the micro soldering too much it's pretty zen. You put your head down to work and hours fly by.
My goal for this channel is to let people see that anyone can do stuff like this. It doesn't matter if you 10 or 99. You know... like Lego
Thanks for the comments, I have some, what I think, are great projects coming soon. More than just practice boards, fidget spinners and LED's.
As for assimilating to the great language of China. As you can see from my grammar I can barely speak English. I'm Brooklyneese so assimilation

@@LetsMakeSt-ll2wx One thing I forgot to mention - and your HVAC experience is prefect. those triods are connected (you can see the traces through the board, in an inner layer or on the other side). Much as your HVAC control electronic could never have a hope of providing the power to a compressor motor, your little chinese board here could not supply enough power to those LEDs without letting out "the magic smoke" contained in every electronic component. Those triods are provided a control signal on one pin that causes the triod to open a much more robust connection to power for those LEDs. much like a contactactor.
Even compared to your HVAC experience, mine is even more dangerous - I write software. I swear the hardware guys wired an alarm to the tool rack to alert the whole building if a software guy grabbed a screwdriver. My wife even does the wiring at home - I'm noticing a theme! (to be fair, I have installed quite-a-bit of wiring, and I'm currently working on my EPA 608 certificate to legally work on household refrigeration equipment that I used to be able to get parts and tools for ...
"Pat" is a great reference (great SNL reference too), but you might also check out brilliant.com (or its competitors). lots and lots of online courses to learn things like electronics. To succeed at your goal of troubleshooting and repairing electronic control boards you will either need a manufacturers guide or significant knowledge. The most likely part to fail is a capacitor, but figuring out which one ...
Your soldering skills are excellent, and you have some good tools, so your goal is very achievable. Knowledge with shit tools and/or shit skills will leave you with shit. These days, knowledge is easier to acquire than skills, to be honest
@@brianhardy9275 So a triode is basically a contact actor/relay the more you know.
I have looked into brilliant but the problem as is with all things is time allocation. Between work and the channel and just life, is hard to sit and take a course. The biggest time killer is editing. I now know why people hire editors. putting together a board takes a few hours. editing a 15 minute video... the voice over is the most time consuming. I hope with experience I'll get faster.
Good luck with that EPA test. Its not too bad but then again I took it 15 years ago so I do not even now what's its been updated with. There are a lot of changes going on in my business and in my opinion not for the better. Most of the new refrigerants are flammable now. I get it with a fridge that takes 10 oz but when you're putting 10-15 pounds in a ac unit for a home... just asking for trouble. especially with the quality of techs out there now. Im not wishing it on people but I foresee a lot of problems in the future. If you're going to work on new stuff just be careful.
And thanks for the soldering complement. It's only been a few months since I started. I think my years of having to be a jack of all trades has helped. Well that and the brazing, wielding experience. I think knowing how much heat to use is the key.
Time to create your own kit Broski!
love your vids
I got 10 points!
