Getting a little depressed from our lockdown pandemic situation in Vancouver andI needed something to get me motivated. So when KZbin popped up your video I was excited knowing that whatever you had uploaded would put me in a good place. And I’m happy to say this was a one of your best offerings to date. As a retired bench tech I enjoyed every second. Thank you!

[@bencorrado]

Great video! One suggestion, if you make more high current boards, leave the solder mask off the traces on the backside between the P-FET and connector and make a stencil for them. You can go from a 2oz copper to 2oz copper plus as thick of a solder trace as you want to glob on there to decrease the series resistance. You could do the same for the supply traces too. Also, my google home responded to your "turn on the lights" command with "Ok, turning on 25 lights" Glad I wasn't watching it while the kids were asleep!

[@MattBlank0]

That was a great overview, thank you! I'm happy to hear that it's so easy and affordable to get professional PCBs. I've struggled to remember the difference between N-channel and P-channel, I've just never heard N=Negative, P=Positive, these are the sort of things that are easy to miss when you're self-taught in EE. This board is almost exactly what I've been looking for, most of the cheap ones are N-channel as you mentioned, I have one just like the 4-channel red one , and it works, but I would have to pull a bunch of new wires to get my truck lights to switch on the negative side. What I would add to your board is an i2c interface, so that a few of them can be hooked up to one microcontroller or Pi without tying up IO pins. How much current are you able to switch before you need to add a wire as shown on your high-power board?

[@craigmckenzie8028]

Thanks for the reply. I have purchased 2- 12v wemos relay shields for my project. I have built 560 ah lifepo4 battery bank for our bus. I liked your video on electrodacus bms, so I ordered 2 SMBSO. I didn’t like the Chargery bms that I was using. So I reconfigured my set up to run the SBMS0. Works as I expected it would. My solution for keeping the insulated battery bay warm when we are not in the bus was to run a1156 light bulb on a manual switch. That does a good good job but a pain to have to turn on and off manually. When we are traveling in the winter my espar d4 heats the battery bay and the basement. Then i discovered your wonderful video on automation and decided that I would learn to use the wemos to automate turning the 1156 light bulb on to warm the battery bay. Moving forward I’m going to try and control the 1156 bulb and 12v fan with a ds18b20 temp sensor through the wemos board. I have set up a partition on my Mac laptop to run Abuntu. Works great. I now can communicate with the wemos. I can control the led on my board with Blynk from my phone. It’s a start. Can’t wait for this Covid thing to end so we can travel south again in the winter.

Excellent video! You have yourself a new subscriber! I would personally recommend getting a new tip for your soldering iron!

Always remember, just because you can, doesn't always mean that you should! The right tool for the right job always makes the job easier, faster and without damaging something!

Is it not possible to have a slightly higher voltage source (higher than the positive rail) to drive the gates on an N-Channel to achieve the same thing. A problem with the P-Channel is its significantly higher internal on resistance...thus heat.

[@Everlanders]

Very cool video. I understand how much time and effort goes into making a video that folks want to watch, regardless of the content. I love both types of content you put out and it is well worth it to me to contribute. I’ve never run across much that is neg switched. Is there a lot of that negative sort of electrical switching in Canada or equipment that you’ve worked with over the years? In an auto, pulling the negative terminal is a must when working on the electrical in case the wrench, you are using to tighten the positive terminal on the starter, hits ground, which is all around. What I love about these tech videos is that you are building damn cool stuff. I’d love to see more on your onboard Pressurized Air system and its many uses on your rig. Thanks for your effort on putting these videos out.

[@Everlanders]

Thanks for the great comments, I'm glad you're enjoying the content. In automotive applications, almost everything is positive switched there will be some exceptions of course...

[@GoatZilla]

I found myself needing something similar. I wound up using an automotive power IC (TPS2HB16). A bit more fiddly (HTSSOP) and expensive, however it has built-in current sensing/limiting and some other bonus features. So essentially it can replace some of your fusing, and it's much more compact.

Hi, great video. This is so cool. Do you have a video where you explained the components you used for your design? I'm in the process of doing something similar for my car, but I would like to add a couple of high amperage 12V devices on there, like a winch. The rest will probably be lights. But I'm trying to learn what's the best way to switch high amperage DC loads.

[@Everlanders]

The winch was probably built with large relays or contactors, controlling these us probably your best bet.

[@jesusakadice]

Thank you for the response. Thanks to your video. Now I know I can do it. I want to switch the relays through the rapsbery pi with open auto and using an HMI screen. Not physical buttons. Do you recommend using an 8 relay board how you made and all the wires (about 10?) Or pairing an arduino through serial comms (maybe i2c or rs485?) with the pi? Also, you go offroading quite a bit. How's has the pi and the screen you have worked out for you? Have they been okay with all the vibrations and heat cycles?

[@Everlanders]

I would caution against controlling a winch with an Arduino or Raspberry Pi. Winches can be dangerous enough as it is, but if you have a glitch in your code or a delay in a process and the winch is running when you NEED it to stop, you'll be better off just waiting the stock buttons to your dash if you want.

It might of already been said or you have already thought of doing it but you could easily move your motion sensors to a esp and then just have that wirelessly feed back into the pi. As a second thing have you ever thought of running something like home assistant as you don’t have to rely on a internet connection.

[@Everlanders]

Yes, the motions are all on ESPs already...

[@waiting4vizzini]

Really amazed by your mobile innovation! Dang... after this one, in Jason I trust! You're the Gilligan's Island Professor that I've always wanted to be...waiting for more coconuts in your life hacks. Once I get a little more Thurston Howell, myself, you guys are at the top of my patronage list, so I can selfishly help to ensure continued vicarious living, through you. Would you ever consider marrying parts of your automation with a project like Travis Goodspeed's Goodwatch (casio calculator watch pcb swap with radio / OOK ability) or does that strike you as being too insecure, for your needs? Seems like a cool idea, at the very least. Just bought the stainless version to scratch my electronics itch. 🤓

[@Everlanders]

Thanks for the kind words! The Goodwatch looks cool, but I already have a lot of our automation available on our Android Wear Watches, although not really used so much these days.

[@waiting4vizzini]

@@Everlanders the unseen side of things... Guess that would give a better handshake and leave a lot less out there, flapping in the breeze. The 25 dollar price point is hard to beat, though. I'll give you a shout if mine makes it into any automations, and ever gets hijacked by any bad actors, in some compelling way. Either way, going to throw my support toward pcbway. Thanks again for the lesson! Safe travels!

Looking back at some of my favorites, and I'm unreasonably tickled that my snarky livestream comment made the video!

[@johncochran5913]

Are you going to sell your pcb files or could I buy one of your boards? Thanks for your great videos!

[@Everlanders]

Sorry, no

[@williamjordan811]

OUTSTANDING!!! Loved It!!

[@davidmiles6458]

Very interesting. Do you make the CAD files available for someone that wants to make/modify their own boards?

[@mrellistechnologyteacher1625]

Would you need the ULN2803 if you were only switching one p-channel hexfet? You have inspired me and I’m working on a project.

[@Everlanders]

Yes, to fully saturate the P-Channel you need to switch the full voltage that the P-Channel is switching... The gpio can't handle that high voltage.

[@mrellistechnologyteacher1625]

@@Everlanders Thanks! I may see if I can come up with a single channel Darlington. Seems a waste to have that full ULN2803 for one hexfet.

[@Everlanders]

You don't need to use a Darlington in this case, I only did it because I had eight channels on that board anyway... For a single driver you could probably just use a 2n3904

[@WereReallyRelayCamping]

just love seeing these videos

[@oklahomaoverland]

Any advice on resources for protecting those P-channel Hexfets? My google fu is not strong enough to find what you did. I'm working on a project that uses one switched by an or gate ic.

[@Everlanders]

I used TVS's from Bourns, PN 1.5SMC39A-Q

[@Spunky.sparks]

Can you get? And is it worth getting populated boards? Cheers

[@Everlanders]

Not worth it for me.

[@NateVolk]

But do you have a light switch on the wall too?

[@Everlanders]

No switches in the whole rig...

[@NateVolk]

@@Everlanders Thanks! I like what you are doing but I really need wall switches too. My wife is not tech friendly! Is it even possible in your setup? Maybe to add a simple switch with power to the relay board? I'm still diggin through your videos. Great work!

[@Everlanders]

Of course you can add a switch if you wanted to...

[@NateVolk]

@@Everlanders Thanks, I'm stumbling through understanding it all :) I get the RV part, and I can do very basic arduino, but tying the two together is a process I'm very much learning! When you said the relay boards were getting fried by your lights, I'm assumming that it was not your led strip lights inside, but your large led lights outside (like driving lights) that blew them eventually?

[@Everlanders]

No, it was our interior lights. They are 120 LEDs per meter and we have nearly 10 m total... They are brighter than daylight, and using a relay without the ability to dim them, it's a pretty high current load. This is another reason having the FETs is nice, because I can dim them now.

[@TMS5100]

Do you really need darlingtons to drive the P channel fets? Or is this just to protect the esp8266?

[@Everlanders]

You'd need some kind of transistor, the big P-Channels need 0 to 12 volts to switch fully, and the 3.3 volt logic on the Wemos would not handle that...

[@billlambright5218]

Thank you so much! AMAZING!

[@charlesrg]

Will you make the board open source ?

[@Everlanders]

I could share the files I suppose, but documenting everything properly so others could follow along probably wouldn't be worthwhile for the handful of people that would use it.

[@charlesrg]

@@Everlanders please share on github, we can colaborate and learn with it. you did a great job on the design.

[@gordizzle26]

Really cool video! I couldn't find anywhere else on your channel where you covered how you are charging the chassis battery, what method/ product are you using to do that?

[@Everlanders]

We generally move every day or two so it's not needed, but if we are stationary for extended periods of time, I top them up with these very drivers built in this video...

[@gordizzle26]

@@Everlanders so does that mean you are connecting your chassis battery and house bank without any voltage or current regulation/ boost? In other words the chassis battery gets the same charge profile as your lithium bank

[@Everlanders]

The current regulation is handled by the software on my driver boards... But like I said, we will probably never use it as we are usually driving every other day...

[@gordizzle26]

@@Everlanders makes sense, thanks. I have a espar hydronic unit and stereo that run off my starter battery, but want to use for extended periods with engine off. I would like to be able to charge the starter battery from my lithium bank to support the battery consumption of those appliances. I already have a Dc to DC charger linking the 2 batteries but obviously it only charges from the alternator to the lithium. I think the best solution maybe just to wire the appliances direct to lithium power. Although I am thinking about trying this unit from Drok www.amazon.com/dp/B076TTBKFG/ref=cm_sw_r_cp_apa_fabc_Y4TTFbDMZAD6T?_encoding=UTF8&psc=1. then wiring the Drok unit to a relay between the DC to Dc charger and starter battery so It can use the same 4awg wire. I don't think I'm ready for your solution yet, but thanks again for sharing!

[@dougnicoll]

Awesome system.

[@virgilmcmayers4974]

By the way you run out of the GPIOs on Pi try to use I2C bus for it.... It will surprise you ... :)

[@Everlanders]

No, I intentionally wanted to have satellite processors that could handle these tasks independently, hold states even if the Pi was rebooted, and for $2.00 its hard to beat the price for 11 digital IO, interrupt/pwm/I2C/one-wire supported pins and A/D

[@cruzdanielgamboasolis7768]

[@RogerWilco1]

You hacked your sodastream to use a CO2 cylinder awhile back, did you need a regulator to reduce the CO2 pressure, or us it all just about finding the right fittings?

[@Everlanders]

Yes, I've got the regulator set to 116psi

[@mozaic_channel]

Thank you for sharing all this info, sincerely. I would love to build a medium size Pelikan case solar generator using PCB where possible to minimize the size of components other than the battery. I think this would really be useful to many people who may travel in different vehicles, even rentals, tent campers, as well as folks needing a backup power source for emergencies but who want to be able to maintain the unit instead of buying a ready box on Amazon (Goal Zero, Jackery, etc... ). Would you be interested in designing an Open Source generator? I’d be happy to contribute pesos, dollars, and time. My electronics knowledge is just enough to swap parts but definitely not enough to design PCB. Anyways, thank you for those videos.

[@Everlanders]

What would the circuit do? Presumably you would need a charge controller with integrated BMS?

[@mozaic_channel]

Everlanders That’s right. What I find with currently published DIY solutions is that the BMS, monitor screen, step down, charge controller, etc... all need to be off the shelf components pretty much, linked by wires. These things can be thinned down quite a bit and battery maximized and also more serviceable overall if some of components reside on PCB. I don’t mean to develop a full on production version, but a board that could accept the main components that DIYers could use to get a unit up and running. Here’s an example of a commercial unit tear down: kzbin.info/www/bejne/nYPLgaKliLWjqLs
