Hi Andreas, I just wanted to write a few words to one of my favourite UKpostsrs. You, along with Great Scott and Ralph S Bacon, have been absolutely wonderful in helping me get through lockdown here in Melbourne, Australia, by introducing me to a new hobby with your expertise and sense of humour. I have had quite the backlog of videos to watch, and still have many more to catch up on. I'm a programmer by trade, but had never had much to do with hardware and electronics until recently. Three months ago I owned a crappy soldering iron and not much more. Now, with a lot of help from you and the others mentioned above, I've completed a heap of projects, have quite a collection of dev boards and associated sensors and accessories, and even bought myself an oscilloscope, and built a 3D printer. I think my transformation to 'total geek' is just about complete! :) I am signing up to Patreon now so that I can give something back to you. Keep up the good work!

I always use "clear protective lacquer" on the boards of outdoor projects, even if i use a tight box. When i access the box in a moist environment, water somehow gets to the components and to prevent corrosion it is a great addition, imo.
@AndreasSpiess 3 роки тому
Thanks for this tip. I once planned a video on the topic (after my humidity sensors). But it never made it on the top priority.
@notmyrealname3462 3 роки тому
There is something called CPC, clear protective coating, and I've used this for years protecting boards in the worst environments. I think it is just a spray lacquer as you mention. If you can orient a box, make sure it has a drain hole. Most problems I have seen is that not that moisture can get in, but has no way to get out.
@BerndFelsche 3 роки тому
Good video that covers many aspects. Those in warmer climates would be aware of the temperature rise of any box in the summer will terminate most consumer electronics within weeks. A simple workaround is to put a simple shade roof over the box, spaced to permit free air movement. The roof gets very hot and promotes convection around the box so that it doesn't get much warmer than surrounding air. Of course there are issues with wildlife everywhere! Even the bipedal! Choose the site accordingly! Also, sunlight will rapidly degrade plastics without UV stabilisers. Choose enclosures according to the environment in which they will operate.

Yes, thank you for the weatherizing tips and another quality video. The moisture removing silica descant packets frequently found in pharmacy bottles can be useful for small boxes. Even the bottles themselves can be used for smaller board/battery projects. Another idea: I have been using 1-1/2" black PVC pipes to contain my PIR sensors/433 MHz transmitter/Battery combinations. The sensor faces out one end and is mounted inside a matching PVC pipe test cap with the knockout removed to fit the PIR sensor. The PIR is sealed into the test cap with silicon caulking. Another test cap (retaining the knockout this time) is fitted in the other end. The nice thing about using the PVC pipe is that plastic gimbled mounting brackets can be glued right to the side of the pipe. The entire assembly is then mounted under the eves pointing at every outside door and window location (six of them). One receiver is indoors and collects/decodes all the 'alarm' signals. All the materials were very inexpensive, though it took me years to build.
@AndreasSpiess 3 роки тому

Thanks for sharing your vast knowledge and testing! I once used containers similar to that to try to keep 3D printer filament dry. Even with a large amount of desiccant in the container, the humidity seeped in and equalized with the environment. I then tried 5 gallon buckets (very cheap and common in the US) along with removable sealable lids. They have worked much better. With 8 ounces of desiccant in the bottom, the humidity inside has been maintained < 15% for over a year even with numerous cracking of the seal to obtain filament.

Well done, as always! However, when choosing a plastic container material for long term projects, pay attention to the aging of polymers due to UV exposure. Some plastics “burn out” and break down rather quickly, sometimes within months, especially those that have been recycled. I also suggest to add a pack of desiccant (silica gel), just in case :) And you can always use good old "Zaponlack" to cover the components as well. It's probably the cheapet way to protect PCBs, but it's hard to re-solder if needed after Zaponlack is applied. All old military-grade USSR-era PCBs, as well as gun ammo is covered by Zaponlack.
@AndreasSpiess 3 роки тому
You are right with the UV. I do not hope for a too long live (and we do not have plenty of sun where I live). For the moment I did not add silica. But I have a 500g bag if needed. I will watch the humidity.
@barman_ua 3 роки тому
@@AndreasSpiess 500g is a big bag :) It will be fine with a way smaller bags. In the end, in such projects It will all depends of temperature/moisture inside and outside the container, the "dew point", and the air float. To actually cool the devices in such plastic cases, it needs some airflow with a lower air temp from outside (since it is a plastic capsule). More convection - more cold air sucks from outside, colder air brings more humidity. So it is a question of balance, and even If the device will produce enough heat, that humidity must go (vaporise) somewhere, or to condensate on some colder surface. Anyway, the project is great, and it is always a pleasure to see your projects and hear your marvelous accent ;)

8:33 additionally this is the right thing to do with flexible wires in screw terminals, as flexible wires can loosen or break off with time, and adding solder to them is wrong. The screw will push the solder flat over time, and thus will no longer work as intended, resulting in a loose connection. One more thing: Wires conduct electricity as well as humidity via the capillary effect, and via the pressure differences created by heating and cooling in the casing. Every connection that has open wiring somewhere must be perfectly sealed against ingress of humidity too, if you absolutely have to avoid humidity in your project. There are special membranes that allow your casing to breathe while not letting through water, minimizing the pressure difference problems.

@emmoemminghaus6455 3 роки тому
Making every thing tight to fighting humidity? Its a fight that you loose every single time! In a UBoat you see immediately where water comes in... in a pojectbox you will never find out. Even when you make every cable tight, one of the overseen problems: The humidity that is already in the box, e.g. if you open the box on a warm summer day there is enought humidity inside to condensate when themprature goes down 10°. Obey a simple rule: "If Humidity comes in, Humidity must have a way out" and its fine. For some applications a almost zero humidity is needed, but those are put into a sealed steel box and have some not so cheap "Membran" Devices to suck the humidity out. But for projects like this, there is no real need for that effort, if the humidity is not higher than in your rooms it is ok. To archive this you simple let the humidity in and out (let your box breath), keeping the hummidity inside lower than outside is simple done by the power dissipation of the content (Its like like a real fight... avoid the fight and you can't loos :) ). E. g. (for the size of this project) drill hole with arround 1cm to 2 cm into the bottom of the box, and glue a 5 cm long pipe (as a water trap) with a fine grill (to avoid insects and break high winds) on the outer side. Keep the box tight the hole should be the only place where air comes in and out, just to keep it simple. There are many other "designs", even some that dont need any heating inside the box or allow cooling by exchange air... and yes this is a real sience, you can spend decades of you life.

I love andersen powerpoles, but I think for this I'd have used a few WAGO connectors. Good luck with the enclosure. I've had so many outdoor projects fail that I'm not sure any more that there is a long-term solution. I've found grease in all the connectors to be vital in preventing electrolytic corrosion when condensation forms. Need to use a grease with a higher melting point than your project will survive and then use solvent to make it flow and dip the connector. When the solvent evaporates you have a nicely greased connector. Another technique I am trying now is to use oil and wax and heat (or maybe solvent). It needs a very small amount of a soft wax to avoid becoming an insulator for signal and low-pressure contacts. Purified bees wax and mineral oil seems to work well, is food safe, and safe for most plastics used in electronics. Don't dip potentiometers or variable capacitors! But feel free to use in the kitchen on wooden knife handles and cutting boards. :)

7:32 Have you considered something that's very popular across factory made audio amplifiers with remote control? One big transformer, bridge rectifier, and voltage regulator for RF part and second, separate tiny transformer for RC part? 2$ chinese module does the job, trafo, big capacitor and bridge rectifier can be easily re-used in your new projects once your friend comes back :) I believe DIY power supply without buck converter noise is valuable project by itself and more viewers will be happy to see such ;) Best regards!

You are right. Linear power supplies are less noisy but usually bigger, heavier, and more expensive. This is why I usually start with a switcher and, if I have problems, go with a linear supply.

The Powerpole connectors are a very good hint, especially with the fused distributor. It had improved many projects, if I knew them before. Something in return: Often an outdoor enclosure should not only be weather proof, but also portable. Your box might not be stirdy enough for rough transport. Also, if the case bends easily, it is difficult to attach components on the inside without too much stress. I am very happy with Peli cases or Peli case clones, depending on the required level of quality. I've glued (with epoxy) DIN rails (for power installation - you find many PSUs and adapters for "smart home" projects with arduino or Raspi) to the inside in the past, which further strengthens them. You can drill a couple of holes into them and, if you take a series of outdoor connectors that uses the same hole diameter for different connections, you get a versatile platform for various projects. If heat is a concern, look for military surplus cases, made of aluminium, on ebay. Some are ready for 19" rack usage, if that is your thing.
@AndreasSpiess 3 роки тому
I looked at those sturdy cases and nearly went with one. But because I wanted to have a big one the price difference was very high. And because I do not plan a mobile usage I decided to go with the cheaper solution. Good to know that they can be extended with accessories. I also looked for military boxes, but here they seem to be collectables and very expensive. And they cannot easily be shipped over distance :-(

Hi Andreas, as usual another excellent video. In addition just a hint from my experiance : Glue over time changes it's "electric specifications". In my previous job I had several repairs because of "layout repair wires" glued to a PCB. It can start already after a year but it could as well take several years until it will either dissolve the coating of the PCB, change it's conductivity to "conductive" or even worse : both ... So it dissolves the protective coating of the PCB and get's conductive. Especially in HF or low energy ( CMOS ) applications this will get a serious problem. Or in other words : If you are going for a long term solution don't use glue on PCB/electrical connections. For the wire ferrules the color is not really standard, it's mainly up to the manufacturing company, it's just an indication for same size within a batch. Refering to the metal mounting plate you did mention, there are mounting plates with holes for electrical installations which might be an option for you ( for example www.antennenland.net/Montageplatten - a google search for "Lochblech Montageplatte" will show quite a bunch ), the benefit of an metal plate is quite obvious : If grounded it's a barrier for electrical signals. In addition I want to add that there are special versions of those cable screws that allow for example RJ45 plugs to pass through even if the whole would usually be to small (there's a cut out with the shape of the plug), some do have the sealing rubber split to be able to put it on cables where the plug is already mounted. I have seen such things for garage door openers, surviallance camers and other stuff where it's needed to have pre build cables to be water proof mounted to something. ( www.icotek.com/de/produkte/kabelverschraubungen or www.ute.de/produkte/kabel-adapter/wasserdichte-kabel-buchsen-und-stecker/wasserdichte-cat5e-cat6-rj45-steckverbinder-kabel/wasserdichte-cat5e-stecker-und-buchsen/nti-rj45-5ewtp-cb-ua.html ) Cheers from across the border.
@Sylvan_dB 3 роки тому
When I researched color ferrules I found two standards. IIRC one was primarily used for most of EU and the other primarily for Germany. I think it was the EU standard that used colors for size, while the German standard was entirely different. And of course you can find ferrules that conform to no standard, but those would not be acceptable for inspected work.
@AndreasSpiess 3 роки тому
Thanks for the tip and links for the "Lochblech Montageplatte". I did not know they exist. Concerning the gland: Another viewer also mentioned them. They are a good idea, but unfortunately very expensive for a Maker. So I probably will stick with the standard ones :-(
@fluffyblue4006 3 роки тому
Nice build. But I'm still worried about moist. Moist is very hard to keep out: during the day, the box heats up. The inside air pressure will rise and air might leak out. During the night it cools down and it might suck in cold, moist air. The moist can condensate inside the box. A lot of commercial outside enclosures have a small hole at the bottom that allows for the condense water to leak out and to keep pressures equalized. I'm not suggesting you should drill a hole, because you spent good effort in making it waterproof. Rather, drop in some large silica sachets and keep a close eye to it. You can easily add a condensate water detector at the bottom end of one of the four wood panel support legs. You can wire that in at the Tasmota. The water leak hole can always be drilled afterwards, if needed. After installing and before closing this box, spray the mating surface of the lid with silicone spray. That stuff repels water and will provide for a better seal. It also helps against car doors freezing shut, in winter. Very interesting project. Please keep us informed about this box. I'm very curious what the outside weather will do to the inside climate. Will it be freezing inside, in winter? Will it overheat when it's in direct sunlight? And what will the relative humidity do?

There are also XT30 connectors (rated for 30A instead of 60A for XT60), they are much smaller and cheaper than XT60. I'm using XT30 wherever I can, only downside I found is that they require power to disconnect them so in some cases It is hard to disconnect them without damaging smaller things (e.g. on double sided tape)

Hi Andreas, I really enjoyed the build video. With a lot of the build discussion being around supplying power to the project I would like an objective opinion from you: I use pc power supplies for a lot other than pc's. They provide the voltages needed, the current needed and are an all in one box solution for a mains powered supply for a project. They are freely available and dirt cheap. What am I doing wrong by using this route to power my projects? You can roast me on this one, and maybe I have offended you by suggesting this. I hope not, as I see pc power supplies as a parallel universe to projects requiring 24, 12, 5, 3.3V, etc? But, one should not scorn on others in the community. What works for the maker is good. And I respect that. Kind regards, Duncan
@AndreasSpiess 3 роки тому
I never looked at them so far. But for sure they are a good choice for higher power projects. This project is one of the first needing mor power than a few watts. It also should be easy do switch them on and off.

Very good point. In my project I had to pay attention between the Pluto and the GPSDO. And I am still not sure if I have to change that and switch the Pluto later that it has a stable clock before it starts. I can only add an additional relay in my setup to achieve that.

@ReneKnuvers74rk 3 роки тому
Sealing a box against water ingress is best done by drilling a small hole. In an air tight box the air will expans and pressure will rise because of the heat dissipated inside. This will force the air out. Then at some point pressure will drop when the internal temperature will fall. This will suck (damp) air in from the outside. Small pressure differences are okay, but the bigger the temperature swing, the higher the pressure difference and the more likely the seal will break at some point. The breathing of the box will have condensate build up in the box. A small breather hole, or the professional solution a labyrinth or goretex plug will overcome this. So a 3mm hole in the bottom will do.

Have you had good experience with the solder shrink tube? I was always taught to push the end of wires into each other. Then twist the ends in opposing direction before applying solder, for a good mechanical connection to support the electrical one. So I saw these but often wondered about the longevity of the connection with the cable just laying next to each other in the connection, only joined by solder.
@AndreasSpiess 3 роки тому
You gan push the cable strands that they overlap. And it depends of course on the purpose. If you need only a few amperes they are ok I think. My wires will also not move inside the case. Otherwise crimping would be better.

Not sure about the UV resistance of the plastic in these boxes.. SOME of them, I have seen disintegrate in a fairly short time, there are, I think, some UV-resistant paints, and also UV-resistant clear film, that is used to cover car paint jobs. You could glue some copper sheet to the wood. For safety, and protection from the elements, perhaps use a 32-V -48 V power supply located at a mains outlet, and run that 32-48 V to the box, so that you have a 'safe' voltage on every part of the project that is in the box. The are may quite good buck converters to get the 32 V to 24 V, but follow them with appropriate LC filtering for your RF PA. Personally, I would prefer to run the fan at a lower temperature, or, if possible, to run it at variable speed (although some fans depend on RPM to make the bearings work ;-) ) COOLER IS ALWAYS BETTER. Possibly, run your 5 V supply from Li battery/cell, so that all power coming into the box can be switched off, but the 5 V can run for some days on battery...if you are doing 'smart' switching, you could even switch main power back on from time to time, to recharge the battery. Having all power off, and isolated from mains, and 'ground', should also alleviate most of the potential (pun) for corrosion. What is the thermal resistance of the heat-shrink material? Will it cause any issue for the SMPS? The automotive connectors may not be pretty, but the ones from European or North American suppliers are totally reliable; they have to be, to meet automotive quality standards. Interesting project, good discussion of the issues, and subjects which always have a plethora of possibilities for solutions! Viele freundlichen Grüßen!
@AndreasSpiess 3 роки тому
Thank you for sharing your experience! As said, I expected a lot of additions from my viewers. This is a big part of the value of this channel, I think! Concerning the thermal resistance of the heat shrink tube: It is for sure not high. But those switchers also do not produce a lot of heat.

What was your setup on the power socket side of the power cable ? I can see how the IP68 cable pass through are handling the waterproof requirement on the box side but I'm wondering how best to handle it on the power socket side.

@mikaluostarinen4858 3 роки тому
There's always some water vapour in the air, and it will condensate at certain temperature. There will be small pressure differences between outside air and inside the box, which can move air in and out. Sometimes it's best to have well ventilated case with drain holes for water at the bottom, if a gas tight case isn't possible choice. Nitrogen filled gas tight cases and cables are used in some applications. I don't have much experience in this area, but I think water tight case can be the riskiest choice, since it keeps the condensated water in but never lets it out. I'm not judging Andreas' choice here, he can manage the situation if he sees condensation problems. Time will tell whether anything occurs.
@toniseenmae6090 3 роки тому
Based on my HAM experience with DIY VHF-UHF antennas and HF baluns, it can be useful to drill a small (1...2 mm) hole into the lowest part of the case. Humidity finds it's way into the box for sure, a small draining hole helps to get rid condensed water but doesn't affect rest of the box much.

Great video, excellent concept to go through the practical details. The only thing that made me say "what?" was 3D printing legs out of plastic, instead of just cutting some short pieces of wood. Don't you have some scraps of 2x2 or 2x4 laying around? Cut four pieces to length in a few minutes at most, then screw with 4 common wood screws, job done. WAY faster than 3D printing legs from plastic, and way cheaper, and way more environmentally friendly, in every possible way.

Just another recommendation from me -- if you need Lab Power supply for 3 main voltages( +12V, +5V, +3.3V) and high current output capabilities -- go ahead and buy ... computer PSU. Yes, regular computer PSU is the best and cheapest option to get quality powerful lab PSU with the most frequently used voltages in electronics and electronics DIY. And everything is provided in one "tiny" box. :) Chinease guys have learned from makers about this opportunity, so you already can buy tiny boards with regular terminals for these voltages( e.g. bananas or screw-in) that you connect to regular ATX cables( those that you plug to your mother board). I hope this will be helpful.

As a mechanical engineer, I am "puzzled" as to how the heat from the transmitter will leave the box. Unless the surroundings are much cooler (fair assumption for Switzerland, 10 months of the year), the plastic box will insulate, regardless of how much the internal fan stirs the air. If the box is large enough and the duty cycle of the transmitter is low enough, then you should be OK. Polyethylene is a good thermal insulator. And it picks up the firect heat radiation as well... From inside and outside. For testing, place a 40W incandescent lamp in the box and close it. Observe the temperature rise. Temperature sensing must be used to prevent the box from overheating.
@AndreasSpiess 3 роки тому
Good point. Fortunately I listen more than I talk. So the PA will only create heat for a few minutes per hour. But I am not sure what will happen. This is the reason for the sensor. I fear more the sunlight than the amplifier, btw.
