I have this same thought every now and then. Especially now that Dave did a new $50 oscilloscope video. Even though the video still holds up, I really want to see a 4K retake with new tips.

Sounds like a plan, and a good one.

@@Bluelagoonstudios My high school electronics teacher was in the last year before retirement and he was very proud of his book on how to run a TV repair business. What's really funny is that this was right about the time when TV repair started to become pointless. As a high school kid I never bought his book of course but years later I decided to look it up and found a copy on Amazon for like $5 so I bought it. He actually did a good job for the time but it's laughable today. Times change and so do labs.

@@dougcox835 I mean… the story is cool and I see where you're coming, but what has really changed in the last decade that would render the basics in this video to be obsolete? As I said, I'd be down for a retake with some updated tips and 4K60 nonsense, but it's still solid as is. It's not like it's forty years old and has Dave telling us to get a logic probe until we can afford or access an oscilloscope. Some things that have changed are prices, specifically mentioned models and the availability of some kits. It's still a good video and following it will still get you started with a useful lab. A new video would really just bring us new tips, things Dave may have missed, references to newer models of equipment, etc. Otherwise, I really don't know if there will be a drastic difference between this and a newer video. Especially not anything that you can't find out with a few minutes of follow up research. 🤔 I don't think a new video is necessary, but damn would it be appreciated and cool.

@@EricYTP Yup, my story covered decades so not quite the same. I would leave it up to Dave to decide which areas might be different.

so true

where can you find some good project ideas, I'm a student just trying to learn

+Renato Pierri Well, I wouldn't have thought of a fire extinghuisher, but it makes sense.

LOL

A first aid kit is nice too, for close encounters with the iron.

@@jamesdriscoll9405 do you do something when you burn yourself? Years have thought me not to bother with that and keep working, as there's not much to do when you burn with the iron.

🤣🤣🤣

I was designing circuits and laying out boards when surface mount technology first came out. I found it easy to get used to and pretty cool. For prototyping we got one of those stupid fancy rework station things but the truth is I could do better changing out components, even QFPs, with simply a soldering iron and solder wick. People would not believe me until I showed them then they were like 🤯 boca abierta.

I could sum it up in a single word: "FUN!" Dave makes electronics fun! No matter why you need the info, business or pleasure, he teaches it the way it should be taught! Many people get into fields they love, but end up getting burnt out because it doesn't stay fun, rather it transforms into something they need to get paid to do! I know this as it happened to me too, but I was on the computer-side for over two decades. I retired as an accountant!

Don't worry, he's Australian, probably has an esky with him at all times

Rick Saffery If you get the proper adjustable temp soldering iron you can also make your coffee. Two birds one stone.

Oh PLEASE! In the UK and Oz a PROPER beer fridge is called a pub and if he's any sense he'll have found a house or workshop within metres of one - fridges frequently run out but pubs rarely do! LOL :)

I have a combined beer and solder paste fridge. Probably not recommended, but it works

MrEdrftgyuji Keeping them together ... no worries ... consuming them together ... hmmmm not so good. 😂

@Travis Ireland hi Travis I've just started same time as we went in to lock down I've would recommend a variable power supply I use i mine all the time ,plus I bought a second hand one off FB a farnell linea £20 and he gave a fluke bench multimeter ,I've just ordered a oscilloscope don't know how to use one but I'll learn ,enjoy m8

@Travis Ireland check out "drone bot workshop" make one out of a ATX power supply out of an old computer,it will give you 3.5v ,5v and 12v,👍

+_ _ ""No I'm not building a spaceship"" Does that fool anyone? Be honest...

+George Tsiros I really don't think he needs to build one... I have a funny feeling they come built in: e{a}/t=hv But you better check real quick and that's super easy to do if you go by the book and use the specs. 1: Turn on a light.... 2: Make sure the photon's clock is not moving for accuracy.... 3: Check your speed. In my book anything over a few hundred thousand miles an hour and it's working. I'm not sure why everyone else is in such a hurry and some people have to get so darn technical and worry about a few Nano seconds gained here and there. I mean it's not like we actually know where we are going anyway so I'd like to know why it matters so much....

?

+George Tsiros It was a joke George... maybe I should lay off the mourning cup of coffee;-) But it is based on proven facts with some logic thrown in. From the photon's frame of reference it's not moving as its clock speed shows. It's the Observer that's moving looking at its own clock move as it moves past the photon's location in spacetime. It's an interesting paradox involving deep concepts of symmetry because the Observer's eyes and senses held in place by the strong force is looking at light being generated by the weak force that powers the Sun... meaning the Observer is looking at a speed of light clock generate the light it sees which should stop the Observer's clock too. The paradox is resolved by adding one of two things where only one choice is correct: 1: A loose cable (As CERN said when the issue came up in 2011: (v-c)/c=2.48e-5 sec gained in 453.6 miles) 2: The asymmetry of the weak force which adds 3.6 seconds a year to the speed of light giving us the intermediary state needed separating the positron (anti-electron) from its electron (neutrino space) and the time needed to move in under the effect of constant time dilation. (As SLAC and others proved by showing SLAC's E158 ratio matched CERN's data creating an asymmetry in time SLAC confirmed in 2012 by using their old BaBar experiment data and "looking at it differently".) The equation e{a}/t=hv (where E=hv to keep it simple) shows the fine structure constant ratio is being maintained by the asymmetry of the weak force and ratio of time dilation in effect. It shows the asymmetry of the weak force {a} is acting like a scales fulcrum keeping E a constant using time dilation as the length of time/space increases. A video of the process would prove a picture is worth a thousand words as it's not as difficult to understand seeing it as it is to explain. We have entered a new era of physics without missing dark matter and energy but as usual it takes awhile for people to believe it before trying to understand it. Cool thing is it only takes basic 6th grade level math to see for yourself as that's all that was needed to reduce SLAC's E158 ratio down to 453.6 miles and the hard part connecting space to time (literally) is already done and posted online. Take care...

@@marbleshark6 Hello, do you still assume your joke 7 years later ? :-D

its "how long is a piece of string" with electronics lab equipment. e,g multimeter $5- $5000, oscilloscope $20-infinity, power, supplies/function generators same story. The fact they can make these things so cheap amazes me as much as how god damn expensive it can all get

Do you do it just for hobby? Are you plaanning a formal education here? Are you making a carrer with it? Just asking. I'm highschool

@Marcin Berman what eo you mean

I learned How an op amp Works thanks to him

furrydog 73 Its 1.6v obviously :)

Yes, that was a bad example ... You're right! ;-)

Everyone knows, you can't trust 1.7v

Befriend a calibrator facilities... to have your instruments calibrated at a lower price ☺

furrydog 73 (1.5+1.7)/2=1.6

I started out that way as well and then found I needed "x" for a project, then "y" for another project and over time my shop ended up looking like his lol. It's true of all trades that work can always be done with basic tools.

I started out like that too. When I find I need an x or a y, I take a sip from my cup of water and simply carry on with the shit I've got.

I need to learn how to do that, instead of using each challenge as an excuse to buy a new type of tool.

repaired 1000+ electronics with old mastech multimeter, selfmade powersupply, old used soviet scope.

@@intesral Respect. In America us old timers call that "ingenuity". I was an electronics hobbyist has a child so I started out that way.

that's basically what the instructions were

Ostrica391 Instruction basically tells to buy the whole shop.

Instructions perfectly clear, worked as intended.

🤣🤣🤣

🤣🤣🤣🤣🤣🤣🤣🤣

Nah...couple of wooden clothes pegs screwed to an offcut of wood. Leaves the helping hand rubbish in the dust

and add an LCR meter with ESR to the list. Especially if you've got a cheapo basic DMM.

Best wishes! The first Scope I bought cost me a thousand pounds (a hameg 20MHz DSO) but last twenty years... Over that time I was lucky to score a better one for free and still pass my hameg onto a new electronics hobbyist... I now tend to buy a decent tool once a month, spending as much as I can on quality, so it will last.

This is the best advice

Then build a better phone than iPhone at a fraction of the price. Mass produce it and make a fortune.

+EEVblog Could you please do a video on your tools that you use for tear downs?

Aaron Gill-Braun Maybe, I failed. But, I was trying to say "watch and learn" from the two videos and put together an electronic lab you need and can afford. Thank you for getting me thinking about the scopes which lead me to this pontification. Personally, the best scope I could afford is mandatory for me then at least one but for me a mandatory minimum of two good multimeters. Then collect everything else as you can afford until you have everything mentioned and more as time goes by. Thanks again and I hope we have helped others on their quest to learn electronics.

ABB is pretty much 50/50 of both countries :P

Son of a Zombie What about Angry Birds?!

ungratefulmetalpansy maybe something related to 'Chock-O-Late'.

shinmai in Spanish they are call Suiza and Suecia and i always have to think wich is wich or i get confused, in English i can easily distinguish them and never get them confused.

is that what you did? what were some of your techniques to monetize your 'hobby'? ☺

One hobby is putting together old computer parts and find uses like home automation. Since I gained parts and skills, people started paying me to repair their computers. They often give me old parts so I have more to play with. I refurbished a hakko FM-202 iron off ebay and invested in Autotrax PCB design so when I explore Arduino and other fun projects I can sell my own kits.

megalomania345 I started more than 8 years ago, some of these come and go. Was this around back then? If I think it's good enough, I'll recommend it to people too. Thanks

What is the bandwidth/frequency range? The android apps I found all only go to 20kHz.

Binj Komisar this is all about DAC in phone. I highly doubt that it can go over 20kHz and also sine-wave can be not exactly sine etc.

Maximum frequency: 22khz, and on my scope the sine is clean. Mind you, I am using a rather outdated 100mhz iwatsu, so some accuracy may be lost there. I don't deny that it isn't as good as a purpose built function generator, but for my purposes with my scope it does what I need.

So shame on me then.. I was thinking that cheap-ass DAC in phones cant really produce nice sine wave.

Exactly. I may buy a real function generator if I need one, but for now, this cheap alternative is best for me.

I find a ream of A3 paper the best value for money CAD tool. Works equally well for hardware and software!!!

Beaverdam Creek Hakko is the gold standard now....can’t touch them for under $100.

you can diy basically everything except the oscilloscope, for any good bandwidth/ sampling rate you need to buy.

Volt Sticks should ONLY be used for fault finding - NEVER to confirm live or dead. There are countless stories of people being shocked because the stick failed to detect the voltage (one I'm personally aware of where a apprentice was thrown out of a ceiling cavity).

+Breaking Elegance I love my 117. It has got far more usage than my more highly-featured (and expensive) Flukes. Wise buy.

+Breaking Elegance That's the idea, build a PSU and get stuff as you need it. You can find most of the parts for a linear PSU in old equipment dumped on the roadside for waste collection. You can find an off the shelf unpopulated PCB and a suitable housing in the shops or online. My microwave went bang on Monday leaving a really clean hole through the cavity lining where the magnetron was. I'm now salvaging the remains for PSU bits, I can use the RTC elsewhere, I can sell some of the other components magnetron is going for nearly as much as the microwave cost. Do be careful with mains voltages though.

Breaking Elegance pfft do you have to much money to buy a fluke? Btw those things are multimeters works fantastic

Seriously? It seems that you don't work with MCUs. The 117 doesn't even have a mA range! My multimeter has that range broken, and it's a big PITA since I can't easily measure the current for the MCUs.

megalomania345 Yeah, more or less. I'm a weekend tinkerer, playing around with electronics for fun with an interest to actually understand how the components work together. Every time I've fixed something it was by sheer dumb luck: fixed a burned out TV by replacing a large resistor, fixed a speaker set subwoofer by replacing one of the capacitors, fixed a Commodore 64 by desoldering the ICs with a blow torch and setting the board on fire in the process (it worked when I was done!). And every one of those times I have no idea how I figured out it was those particular components that was shot.

Taking apart old stuff is so much fun, and you can harvest a lot of components that way.

Skip the digital oscilloscope and just go with an analog one for now, then, if you're not doing specialized work that requires the storage capabilities of digital one. Can always buy the digital one later. You can also try going for used gear for other stuff like a soldering iron (though do buy a new tip for it if the included tip isn't in good condition).

Hello there! You can get an old analog scope for about 50 bucks and it is pretty decent! You can also get a soldering iron for about 10 bucks-just go for the transformer pistol-shaped one with a copper wire tip. I've even used it to solder SMD components-even the really tiny ones-and it's doable, even though it's not recommended due to the risk of overheating of your components. As to the multimeter-I still have my $5 one and it's okay for sorting resistors, checking for continuity (short/no short), measuring if batteries are ok and if the wire is live... And you don't often need more. Also-you can easily build a lab supply out of an old PC atx power supply-just add some dummy load (resistors, bulbs...) cut off the connectors and connect the green wire from the motherboard supply to ground. And you got yourself a switchmode 12v/5v/3.3 V high power short circuit-protected supply. You should also get some cutting pliers and a lot of wire-or else you will constantly be running out of it. But I think $50 will get you started in 10 seconds flat.

I usually don't really buy the point that an analog scope is good to start. When I first got into electronics a couple of years ago, I started with digital, not analog. An analog scope is really no good for debugging SPI signals.

Yeah, well, that depends on how you start with electronics. If you're like me, you started with MCUs and digital (I already knew programming when I started with electronics, so that part was easy for me).

To be honest, yes and nope. They last a really long time and if you are a hobbyist only, you can get away with home made or cheap ebay stuff many times. If you spend a long and by that I mean *really damn long* time looking around and searching reviews, you can cut on prices. For example I found a site in my country that sells stuff with 5$ 2 day shipping for many times better prices than ebay and I buy from them occasionally. They sell with discount per quantity too. What you should do is NOT just hitting up ebay or google, but local electronics forums and try to find out where people buy their trusted stuff

All of this is for a price of an iPhone, so take your pick. A useless hunk of metal that can break at any point in time ending with you losing your data. Or a possibly lifetime's worth of workshop supplies to keep you working and curious!

Links? Google is your friend, but start with places like eBay.com (.co.uk or wherever - obvious), Banggood.com, mininthebox.com, lightinthebox.com, gearbest.com, any others you can find doing tools and electronics parts. Avoid JUST Google and Amazon when searching for a lot of modules and electronics - they DON'T show the best deals (sometimes missing complete sites!). That MAY be due to the way in which the site is constructed and not being Google friendly. I FREQUENTLY find stuff easily on eBay that NEVER shows up in a Google search. Use AllDatasheet.com for component datasheets, but do not forget Datasheet Archive and others - Google IS good for finding stuff like that. For components and especially in the UK do not forget places like Farnell (Element14) or RS (rswww.com) order before mid afternoon and it will usually fall through your letterbox before the following afternoon - STANDARD service!
