PCB Assembly - Landing Model Rockets Ep. 7

[@mistyo.5418]

Do I actually plan on ever building one of these? Not really. Am I going to watch every second of this video? Yes. Yes I am.

[@upmanyubhati]

Lol same

[@daphoosa]

Very nice tutorial. One point of advice. The cantilevered IMU is an invitation to excessive vibration noise in your data. You should attach it to the board with double sided foam tape (thicker than the header spacer) and then solder it. This damps the vibration. An even better solution would be to attach the IMU with double sided foam tape, and then use loops of very small diameter wire (I've use 30ga stranded) to attach it the main board. This will produce even cleaner data ( speaking from personal experience with IMUs on flying machines).

[@dopedreamz]

3M makes a really amazing double sided foam tape and is wide enough to cut out to fit.

[@weasel.3683]

or use hot glue...

[@vipera7448]

Phillip Schmidt what do you mean?

[@sashamuller9743]

can't you just use a high pass and low pass filter? kalman filters? sensor fusion? complementary filter?

[@daphoosa]

@@sashamuller9743 Filters are ALWAYS inferior to physically preventing needless vibration. A cantilevered sensor is a "tuning fork" that will vibrate strongly at the right frequency and magnitude. Good physical vibration mitigation followed by digital filtering is the best way to insure good results.

[@donpollard9460]

Two things: I did a high reliability soldering course as part of my Certificate iii in Electronics Trades at our local Technical College. So I make the point that leads should be snipped to the correct length BEFORE soldering, otherwise you will have exposed leads that can can oxidise this may be a problem depending on how many times you re-use the boards - this is a rocket, after all! It is permissible to slightly kink the leads once they are in the board - this will hold the part in the board without stressing it, whilst still allowing relative ease of removal should this be necessary later on (if you let the smoke out ... !) Otherwise great job, Joe!

[@Charly_5V]

"This must be so exciting to watch". You are wrong. This is oddly satisfying XDDDDDDDDDD

[@technicallydifficulties7094]

He's like the Bob Ross of electronics

[@TroyEagan]

Yea. Bob Ross vibes. If Bob Ross was an engineer.

[@frowin2]

Just a minor hint to improve reliability even more: When you cut excessive leads of e.g. resistors, you put mechanical stress on the joint (solder/wire/pcb interface). This may lead to microcracks which eventually (in combination with vibrations) turn into a faulty solder joint. These faults are hard to find, especially when they only occur on a non-regular basis. Drives many people crazy. Reheating after cutting the leads may relief the stress in the joint. In the best case you may also add a little bit of flux because the one in the solder evaporates very fast. It‘s a very rare event but yeah, we‘re talking rocket science :b

[@notaname8140]

It's also worth noting that you should try not to cut more than 1 lead at a time, because that can put torque on the piece and damage the joint even more

[@drakep271]

Stop it Joe, I'm starting college in the fall and you're making me consider adding an electrical engineering minor on top of a computer science degree! Keep up the great work, your videos are so inspiring and educational :)

[@UnlikelyToRemember]

You might want to consider Computer Engineering, which incorporates elements of both.

[@Maplish298]

Great video Joe! For some odd reason, I absolutely love watching these long videos and I find it really interesting and fascinating. Thanks for the vid!

[@dannyallyn223]

anyone else disappointed he didn't count the pins on the processor.... I'm really good at counting to 8 after this vid but no higher :( Love you Joe! Learned more than college taught me from this series

[@darrenjattan4277]

Hey Joe I'm from Trinidad. I admire your work on what u are teaching me & others It's cool & awesome That's like u are teaching someone who knows nothing about mechanical And your work will make anybody reach someway. From nothing to something or many things. Keep going & adding

[@charlesm3232]

Hey im so glad youre doing what your doing thank you so much for inspiring people and educating them on model rocketry or rockets in general:) keep it up

[@dopedreamz]

I honestly don't know if he realizes how important this is but he is making advanced rocketry available to people who otherwise would never even know where to start. He is also inspiring the next generation of space x engineers and helping us get to mars and beyond.

[@k1ng401]

He’s inspiring me too in the areas of electronics and mini computers. I’ve found my old Raspberry Pi which I had only used as a streaming media hub in the past and learning how to wire and read inputs and outputs to it and program it because of this guy.

[@henriquegc737]

man this series is like... the best thing I've watched in the last few months

[@afonsocouto2633]

"this is my little space program and I can do what I want". Mankind must protect this man at all costs

[@LeoTheHuman]

2 recommendations: 1. Start with the less heat sensitive components, like resistors, and only solder expensive boards after everything else is in. 2. Use blue tack instead of the blue tape for better alignment out of the box.

[@9A4GEMilan]

At 3:50, you use sheet of paper for parts, but I am using KiCad for that - on the screen, there are two things; schematic and PCB layout. When click on some component on the schematic, on PCB layout it automatically highlight place where that component goes.

[@tomgeorge3726]

At 20:12, DO NO press in the LED like that, you have now stressed the leads and where they connect to the LED substrate. Pre-bending the leads would have been better. At 24:30 , please Joe, don't pull the lead through, you have now stressed the wire to resistor substrate connection. At 37:00 do you have the two capacitors that are suggested to be fitted to the input and output of the LM7805 reg? Without being able to check your schematic, I may be wrong.

[@MansellRa]

Keeping the BOM updated (including the designations for each of the components on the silkscreen) and completely filled out throughout a project can take a lot of work, but it is sure worth it!

[@TheRealJavahead]

Hi Joe, try using a bit of header pin (with pins removed) as a spacer to ensure your boards are parallel while you solder. Will save you time, reflowing and eyeballing it. As usual another great video. Cheers - Mark

[@lamma3282]

I have actually build one of these and learned PCB designing through these tutorials. Over the course of 4months, lol.

[@tritile]

I like very much this mother board PCB style. I've been using it in my own designs recently. You can find a shield of pretty much every basic circuit so why explode them and end up with a list of zillion components to buy and have in stock when you can just make a motherboard to join them all! It saves so much work and it still looks cool.

[@WisdomVendor1]

Watching good electronic soldering is like meditation to me :)

[@mateuscrevelin3394]

[@NavySeal2k]

You can speed up your assembly by going from flat stuff to high stuff and soldering on a silicone mat. So you can put in all resistors at once turn it around and lay it on the silicone mat so everything gets pushed flush to the board. Than you only grab your iron once for all resistors. Than use the next higher components and repeat. You will waste much less time flipping your board and grabbing the iron.

[@sayedmuhammadidrees1453]

You are my inspiration.

[@GeekGarageDK]

for the next board for the sensors, you should solder on the header pins, remove the black spacer and then either push the board down so the BLIP PCB and the sensor PCB parallel to, and right up against, each other. Even better, would be removing the black spacer after soldering on the header pins and then add double sided gel tape from 3M for a parallel PCB mount, clean and vibration dampening solution (up and down), just remember to get the strong adhesive version :) The last is what i use when i do PCB on top of PCB and they need to parallel to each other :)

[@zggtf211]

So this video is a little bit old and I didn't see anyone say anything, so I figured I'd say something. Maybe you will see this and understand. You should invest in a resistor bender for thru-hole components and NEVER pull them thru with plyers. Pulling them thru could cause cracking in the resistor and change the resistance or break the connection all together. I don't think they fail open so you shouldn't have that to worry about but that could be different with decoupling capacitors. Also, using a resistor bender eliminates the same sort of issues in components. amzn.to/2HuXlxZ Something like that should eliminate those potential resistor failures. One other think is you could add a dot of silicon onto the inside of the side cutter jaws above the cutting edge. As you close the cutter, it will grip the end of the lead and keep it from flying across the room.

[@StevenStewart1861]

That's a lot of soldering lol. If I may, I'd like to recommend maybe trying some external flux. I realize you're using rosin core solder but I find with the cheaper stuff it works Ok but there usually isn't enough flux in the core to do much good. For normal every day electronics this doesn't matter (unless repairing something old and corroded), however since these are control computers for a model rocket but a rocket nonetheless, it really needs solder joints that are as good and rugged as possible. This way you don't end up with headaches down the line that are due to a few bad solder joints that broke loose during a landing impact because there was a little too much oxide on the pad/component pins. This is more of a "save yourself a headache later" thing than something that is absolutely necessary. But I think since these boards are going to be exposed to the elements somewhat, it makes sense to get as good a solder joint as you possibly can as this will keep corrosion (due to inevitable moisture ingress) at bay and as I've already said leave you with stronger, better solder joints in general. I can personally recommend Amtech's NC-559-V2-TF it helps make really good solder joints and is relatively cheap (one tube goes a long way). It is a "no clean" soldering flux but I find that sometimes it can leave some residue that if need be, can be cleaned up with rubbing alcohol. Here is the amazon link to the product I'm talking about www.amazon.com/AMTECH-NC-559-V2-TF-No-clean-Solder-Dispensing/dp/B01N8ZX7ZQ . NOTE: This is not an amazon affiliate link, I am simply sharing a product that I use and like.

[@BPSspace]

Wow!! Thank you so much for the info! Added this to the cart, this is great advice. Over a year or two I do see corrosion on heavily flown computers so that should help a bit. 🚀

[@StevenStewart1861]

@@BPSspace Also, being that the nature of these boards is to be outside in potentially humid environments, I think once the board's are more hardware locked (ie. you don't expect to make any significant changes to the design and it's already tested and known to be a good one) it might be a good idea to look into some kind of conformal coating. I don't have much experience with this stuff but it's the industry standard in protecting electronics from moisture and fine dust. Although you would have to make sure to leave the barometer uncovered, for obvious reasons LOL.

[@Bungee75]

Hi I have electronics background and experience and here is a tip for soldering things like teensy, Solder first (or last pin) and then solder the diagonal pin opposite to it. That will ensure that your part won't move when you're soldering other pins. I have to say your joints look nice, you'd pass my soldering school ;)

[@Bungee75]

Expansion on my tip, start with two most distant pins ;)

[@Bungee75]

Idea for next revision. Mosfet with low enough Ron could be smd version also for the vertical resistors (0805 size). And if you'd mount thet resistor before putting on that SD card board you'd never notice that it has a "problem".

[@Fernando-hp6hp]

You're videos are very helpful 🇧🇷🇪🇦😉

[@gustavocirelli4655]

Hey Joe. Great video, as always. I'd like to recommend a business card book holder, I'm not sure the right name, but it's like a binder with card-shaped sections. It's a great way to organize electronic components.

[@mdotzert4754]

Did you fix the problems with the Blop board so that it works? And could you tell me how much the boards weigh.

[@donpollard9460]

You wondered what a tantalum capacitor was - they are quite small relative to an electrolytic, they are more suited to rocketry, and they come in smaller voltage values then electros - it is good not to have too high or too low a voltage on these components as too high a volt6afe and you run the risk of them not forming properly or too low and you run the risk of them exploding. Electros and tantalums don't like reverse voltages - when I did my TAFE course as previously mentioned, a circuit was set up with a PSU down one end of the lab and the tantalum down the other end and 2core cable connecting the two, the class members were down next to the PSU and when the PSU was turned on ... a crackle followed by a BANG - they make great detonators! I made a mistake when wiring up a bridge rectifier - I got the first diode wrongly placed so the others were also back to front too - more crackling and I built my first model rocket (the plastic wrapping and the aluminum can flew up past my face - just missed my eye...

[@PatrickKQ4HBD]

[@flihx2218]

Great vid! Even though your soldering is great already, heres a litte tip for you: Use a litte bit less solder, and let it flow for a bit longer! But watching you solder for 50 min was very satisfying! (Btw most of those solderspots look great already tho :D)

[@IntRocketLaunch]

Damn Son that intro made me cry with joy

[@MrKen59]

Curious, given the forces and vibration, I’d think you’d want to add a bit of adhesive to prevent the boards (levers in this case) from excessive movement. Could create false readings during flight. Just a thought. BTW, I love your patience and wonderful personality.
