Lazy Sunday - Wireless FM Microphone Kit

[@Spector_NS5_RD]

that's a quality mic you got there, Julian. almost studio quality! it might sound even better if you install loads of blinking LED's around the handle.

[@MOHAMADGHOUL81]

That's simple project and basic, it doesn't need a trimmer and the coil has no need for winding, already on PCB. And the low transmitting range is comfortable for home room distance. Thank you for your spending efforts.

[@wmonger]

Mr. Microphone... "Hey good lookin, I'll be back to pick you up later"

[@Bob3519]

This also reminded me of "Police Academy " when Steve Guttenberg went under cover with a Mr Microphone taped to his chest.

[@ThatGuy-nv2wo]

It's Tuesday! You can't fool me!

[@doughy67]

got s double take in there with your power bank but enjoyed it

[@JulianIlett]

Editing mishap :s

[@noisysprings]

Thank feck for that.... Thought Julian's voice had finally hypnotized me!

[@websitesthatneedanem]

got s double take in there with your power bank but enjoyed it! :) NB: You need a better soldering iron stand... your current one is just a bad heat sink!

[@5speedfatty]

just went to comment the same. pretty cool kit though none the less

[@websitesthatneedanem]

Martin Rabson - The soldering iron shouldn't touch the spring, it just forces the iron to stay on all the time trying to heat up the metal! Most holders have a heat proof 'plastic' holder that fits the iron and holds it centrally. Look up "weller solder station"

[@rwbishop]

I have an old school degaussing coil intended for CRT's; had it for eons. ID measures about 11 1/4" (286mm), and works great for most anything you can pass through it... or wave it over for all that matter. With coil & tool/s held at arms length, energize coil, bring coil & objects together and wave through coil, then separate *before* releasing coil switch. Full cycle only needs to be 7 seconds or so. Check ebay for the coil's...

[@stevesm2010]

I used to use one of those degausing coils in my very first job eons ago :-)

[@jayherde0]

For your nippers, take any magnet and touch it to them. Then slowly pull them apart to to pull all the tiny magnetic pixies out of the nippers. Pull them apart quickly to leave the magnetic pixies trapped in the nippers. For the mic 'pop', putting a glove on it can be handy! :-D

[@himselfe]

I like to imagine one of Julian's neighbours was sat in his house thinking "this isn't a very good pirate radio station" during the making of this.

[@DavidFowlerEngineer]

Watch the clipping wires, I've blown up a bench power supply that way. A lead managed to slip right through a vent hole and into the PCB inside. Boom!.. I recommend that you keep a finger in contact with the leads as you clip, just to dampen the energy a bit.

[@stevesm2010]

You and your 'Poofs' :-) I was taught 'Puff' when I was a teenager so that's my version. A quick way to de-magnetize your side-cutters is to hit it with another piece of metal. Obviously not causing damage in the process :-)

[@MrBrymstond]

Clipping. Turn the gain down on that high end sound system and adjust the equalizer. Top of the line High Impedance microphone at top dollar.

[@andymouse]

do ya no "hard rains gonna fall" the Brian Ferry version ?

[@BillyNoMates1974]

should have named it the Sunday Lash up Kit build Distort-o-mic

[@kyoudaiken]

You got me to the ground. I can't stop laughing. :D

[@johnbouttell5827]

Feels like Sunday -- it must be half term. Jolly good. Carry on. Testing, testing ...

[@backofficeshow]

I am absolutely loving the increasing frequency at which the kits from China are coming with Chinese or even zero instructions, adds a little bit more of a challenge 😂👍

[@DAVIDGREGORYKERR]

I would have thought that a better way to go is to put the local oscillator through a phase splitter to get I and Q then I goes through a DSB modulator then combined with the Q phase then quadrupled up to the required frequency, (I think the method is the Amstrong FM modulator)

[@chartle1]

When are you going to put together that Transistor Tester Kit from a few weeks ago? I just got a grey bag from China yesterday and guess what was inside. :)

[@thomasharkonnen264]

At 11:46 and at 12:37 I started to wonder how is your weather over there in the UK. Are you enjoying it?. If not do you bet it would get nicer soon?, or would it take a while longer for the weather to stay nice?.

[@pdrg]

Little knot in your antenna cable will make the strain relief more strain relieving :)

[@thehappylittlefoxakabenji8154]

foxy says most of these circuits seem to work best when untidy as I made a really neat job of one and couldn't get it to work at all !

[@JulianIlett]

Spot on :)

[@rasmusrunekiilerich2191]

I was told, way back in school, to bend and then cut the wires before soldering to avoid any stress on the solderpads. Myth?

[@JulianIlett]

Certainly cutting the legs before soldering would mean they get in the way less.

[@hrnekbezucha]

So if you put a jack instead of a microphone and plug it into a phone or something you can use a radio as a wireless speaker, right? Or make a pirate radio station.

[@TH3L0LB0Y]

can you mod it with an better mic so its sounds little bit better ? btw great video :-) and greetings from germany :-)

[@petehiggins33]

Did I see you cut a piece of black wire off that carefully tuned quarter wave dipole 100MHz antenna? Only joking, I think that's technically known as a piece-of-wet-string aerial.

[@maicod]

did your neighbours complain that there was some weird show on on their radio ;)

[@tinygriffy]

Im deaf now... also my speakers were acellrated out of their boxes dragging a trail of red glowing copper wire ... anyhow, entertaining as always, thank you !

[@TKomoski]

Julian you should have tied a knot in the antenna just incase you imitate Roger Daltrey ...

[@joinedupjon]

This must be a close relative of one of the first things I ever made... course that was marketed as a bugging device (cold war was still on & everything) TBH never was sure what was doing the frequency modulation but afaict RF stuff just works by magic dancing pixies - the pixies were pleased with the spiral track and agreed to do the appropriate dance on it.

[@MartynDavies]

In the spirit of deja vu, I'm going to say: "the LC / transistor circuit looks like a Colpitts oscillator"

[@ZaneDaMagicPufferDragon]

I'm going to start doing my own Lazy Sunday and start soldering some small kits from eBay every weekend!!! I can definitely use the soldering practice, my DSO138 Oscilliscope kit was complete yesterday after a month and 2 soldering irons later but it's working!!! ;) Looks like shit, but it's working. ;)

[@paulsengupta971]

Two soldering irons?!

[@proluxelectronics7419]

Try washing your cutters in thinners, resistor leads shouldn't be magnetic, some diode leads are......

[@johnhill5745]

The black wire was supposed to be 15cm long for maximum operation.

[@thehappylittlefoxakabenji8154]

I think the screwdriver gave the circuit a bit more of a ground plane

[@FischOderAal]

I was kind of expecting Windows to install an update again :D

[@WilliamDeboer]

anything that can be done to improve it, like a better mic or boost the output power?

[@JulianIlett]

Not really, the circuit is very basic. The mic module is probably good quality. More power would need a higher battery voltage, but this circuit is designed to run from 1.5V

[@tonyfoster61]

You know that It's illegal to operate that in the UK Mr Ilert?

[@TheDutyPaid]

No idea you used KZbin editing... why did you turn off the extra lighting? ;)

[@kyoudaiken]

I laughed so much when the feedback sounds came in. I dunno why but it makes me laugh. :D

[@sazman2000]

great keep-em coming Julian

[@alynicholls3230]

which transistor does this use?.

[@PetRatty]

those poundland power banks are great, small and lightweight

[@SpeccyMan]

They're even better when you take the totally crap cell out of them and put in a good one.

[@josecg7008]

Julian do you know How far can it transmitt?Greetings from Cádiz. Andalucia. Spain

[@josecg7008]

what about make a spy microphone with that??

[@andymouse]

for the life in me I don't no how to describe the thing your using with croc clips like a second pair of hands I want to buy some but my ebay search has come up zilch what do you call them pls ?

[@andymouse]

cheers bud! gonna try that

[@andymouse]

thanks again just got exactly what I wanted! it really is good to talk

[@stevesm2010]

Helping Hands

[@Enjoymentboy]

Do a search for 3rd hand. You'll find what you're looking for very quickly.

[@andymouse]

yep cheers all got mine on the way!

[@TheRealSasquatch]

déjà vu again ;-) love the use of blu-tack as well.

[@Madness832]

Reminds me of the 70's toy, "Mr. Microphone."

[@TheDutyPaid]

I hit F5 all the time waiting for a new video.

[@JulianIlett]

I wouldn't want to be your F5 key!

[@jeffmerlin2580]

You might get slightly better range with the radio antenna extended. :-)

[@JulianIlett]

Kind of deliberately didn't do that so I wouldn't get into trouble with copyright if a piece of music came on.

[@PhilXavierSierraJones]

I am getting 404 error when clicking on the bell. Anyone else having this issue?

[@MobiusHorizons]

Waiting for Davit Watts' comment ...

[@MrBrymstond]

FM Transmitter?

[@webchimp]

Try running the edge of a magnet over the cutters.

[@joinedupjon]

I achieve pleb level degaussing by hand oscillating a permanent magnet over the magnetised part and slowly moving the magnet and the tool apart... just don't do it when anyone's watching.

[@ianbraun8000]

What is that light thing @julianilett

[@RobertShaverOfAustin]

Why would copper wires stick to magnetized cutters?

[@paulsengupta971]

Copper?

[@RobertShaverOfAustin]

Yes. Copper is a very good conductor and used widely in electronic components. Silver and gold are better but are also non-magnetic. Could be aluminium but also non-magnetic. Just wondering.

[@petehiggins33]

Most resistor leads are made from tin plated steel, copper is too expensive. It's been that way for at least 40 years. Copper is only used for high power resistors where heat conduction through the leads is more important. Glass bodied components use other alloys which have a temperature coefficient of expansion matched to the glass to prevent cracking.

[@RobertShaverOfAustin]

number 33, Wow. Thanks, I didn't know that. Glad I asked because I know a tiny bit more today than I did yesterday.

[@coxyofnewp]

I missed the sale, it's to rich for me now,with that $3.59 price tag!! ;)

[@coxyofnewp]

Thanks Paul for the link, but I was being a little sarcastic about missing the sale,sry. But thanks anyway - people on Julian's Ch are really nice peeps, just like the man himself !!

[@paulsengupta971]

I recognised that, but thought I'd post the link anyway, as I was just browsing around AliExpress and came across that! :*)

[@coxyofnewp]

Thanks Paul !! very nice of you.

[@pfeerick]

And it's 5% off for the next 7 and a bit hours on the AliExpress link that Paul Sengupta posted... so don't miss it!!! lol :D

[@stuartabercrombie3903]

RIP headphone users !!

[@nicnl255]

Oh noooo, you missed all the capitals in the title

[@gizzymoee]

Julian Illets pirate radio! (You need a license to broadcast in that frequency) :P.

[@andymouse]

ya supposed to rest on Sunday!

[@JulianIlett]

Dammit, I knew there was something I meant to do ;)

[@andymouse]

Hahahhah!

[@solidamber]

this must be the same mike they use on the indian and nigerian news channels on sky tv

[@websitesthatneedanem]

Julian, buy yourself a new soldering iron stand... your current one is just a bad heat sink!

[@mc_cpu]

Is that thing legal? Though the range is hardly going to cause any problems. ;-)

[@KillerSpud]

Below a certain radiated power it doesn't matter in most countries.

[@iceberg789]

the signal hardly goes beyond your yard. so, practically no one will care about it.

[@kardeef33317]

tie a knot before the antenna leaves the strain relief if ya want.

[@dtwistrewind7361]

blutack is also my weapon of choice

[@texiphone]

R.I.P Headphone Users! I am now deaf...

[@tbddevelops]

Good timing, you didn't edit the video in time, now it's $3.59. Pfft.. such expense!

[@edwardfletcher7790]

At least the distortion will help cover up the sound of the singing most people will be doing...

[@davidwebb2318]

I feel a demagnetiser review coming soon....

[@muh1h1]

You could write "lazy sunday" in capital letters, maybe that would look a little better ;)

[@JulianIlett]

No need to shout ;)

[@brancarr1]

R.I.P headphone users....

[@JimmyThomasjtpro14]

But it's Tuesday...

[@K7AGE]

Don't give up your day job.

[@JulianIlett]

ok

[@FLYBYMEable]

Title should half ass Sunday build.

[@SpeccyMan]

All our asses are full in the UK.

[@squalltk1]

A glitch in the Matrix

[@Davedarko]

No coffee though. And nothing in it.

[@brucewoods9377]

Just give your cutters a few decent taps with a hammer, that should demagnetise them

[@olbrzym11]

This looks like world famous 1 pound powerbank from Poundworld. I have tested battery in one of those and it came up to a whopping 624 mAh (at 0.5 A discharge). And since those lights are rated at 1.2W you can expect less than 40 minutes of run time. Not brilliant.

[@SpeccyMan]

I've modded all mine and put in a quality 2600 mAh cell.

[@thanhnhan8871]

You can for me cirsuit schemetic

[@mrtom64]

I like watching your videos but this one would give an aspirin a headache!

[@amysuresh4292]

See the sound is coming distorted it is not a professional grade mic buy it to learn

[@Flav_M]

HEADPHONE WARNING!!!

[@i-will-get-you-there]

Haha Singing badly with that! Cheers

[@BeNiZzz265]

totally copied from David Watts :(

[@JulianIlett]

Maybe he copied me ;)

[@rusty-]

I bet that David Watts doesn't have a green sponge with a smiley face!

[@BeNiZzz265]

Greg Wilson yeah, he doesn't have this sponge 😀

[@iceberg789]

he did not have the half medusa lighting either.

[@DavidWatts]

I prefer inspired with permission :-)

[@microphonee]

ouch

[@amysuresh4292]

Also thanks this tutorial is helpful I cannot read chinease

[@NivagSwerdna]

China cheap factory quality soldering... very apt.

[@JulianIlett]

I'm enjoying your blog - particularly your reverse engineering of the 12F675 demo board code. Mind if I show some of that in a later tutorial?

[@NivagSwerdna]

Free free. Glad it like it. :)

[@mrgreenjeans9839]

👍✌️👀👽🔥💨💨💨💨

[@akarshagarwal4516]

David watts this is your lazy content. hmm. Jullian you aren't monetizing this video right?

[@SatyajitRoy2048]

Its a toy...

[@adithyapillai4259]

First! Hii Julian 🙂🙂

[@AxelWerner]

just another sponsored content video. thumbs down again.
