Julian's Postbag:

[@ufohunter3688]

I love how goofy some of your mistakes are. Never edit your videos to take them out. They show you are genuine. Please do more videos. Your videos are a treat and shows good stuff.

[@JulianIlett]

I'll be making fewer videos for a couple of months, but from mid October things should get back to normal. Cheers :)

[@ufohunter3688]

I am super sad now :(

[@videolabguy]

@8:05 I can clearly see a PLUS and a MINUS symbol stamped into the metal tabs on the super caps.

[@JulianIlett]

It's so obvious now - doh!

[@PaulJosephdeWerk]

Julian Ilett it's those "doh" moments that get you every time. ;-) If the arrow wasn't enough (almost always points to negative), the stamps in the tabs should clear things up.

[@maicod]

+Julian Ilett filming and talking takes half 'your' brain away, that is why using mobile phones while driving is so bad

[@JulianIlett]

It's true! As well as the electronics stuff, I'm thinking about sound, composition, lighting, pace and all that stuff. The video making process is a real distraction. :)

[@maicod]

+Julian Ilett still hope you keep making these great videos. I hope your course goes well.

[@AdammP]

Those pots look nice and quality. Seem like they have a nice dampened feel to them. They look well with the knobs on

[@JulianIlett]

The pots came from Tayda.

[@nickpelov]

the timer started counting up first time you turned it on. you can try holding the start/stop button or pressing min + seconds together

[@ramrod126]

I bought the 2600 piece kit a couple months ago. Pretty good deal I think.

[@Durrdalus]

Bought the same resistor kit few months back, was missing the ones I needed at the time (100R) but 3 had doubles and an additional random value was added.

[@sarah1390]

same experience. I bought one of these packages myself so I could do some farting about projects and for a decade resistance box for when I am breadboarding I do not have to fool around with having to find some resistor for testing purposes. I love the price but definitely read the values and take some measurements before using. when I received mine I did receive a few doubles but a few values missing after re-labeling some due to incorrect values being printed or stamped on certain bandoliers. Though these assortments usually do cover the EIA values for 1% values as I sat down wondering how I was going to sort these resistors for storage and ease of finding what in the heck value I want. They did not just give you the dross- it is normal in the higher ranges especially with lower tolerence value capacitors that they usually go for a resistance value in the middle of the spread so it does look like values are cherry picked. good explantion of the values included www.resistorguide.com/resistor-values/ Also still need to sit down and create what I would like to call a cheap thumbwheel switch decade resistance box which is what I originally purchased this assortment pack for. Though debating wheither I should buy surface mount or through- hole components for when I build my decade resistance box.

[@thomasleonard5260]

WKDworks I got one that only came with 7 different values. The total was still correct. So I now have more 47k ohm resistors than I know what to do with ...

[@emaglott]

try pressing min and sec at the same time to see if it resets timer to zero.

[@JulianIlett]

Yep, then it counts upwards :)

[@tiger12506]

I wouldn't even begin to worry about backfeeding those B3603 modules until you remove the input voltage. Having said that, I've backfed them even without input voltage with no adverse effects. The only reason I would consider it a problem was because it completely backfed and drained the supercaps I had on the output by powering the module. Module worked normally after I installed a schottky on the output, no (apparent) harm done.

[@leejones8050]

Julian.. I've never shouted at the TV as much as i have watching this video. Shouting "the markings are on the tabs" on them damn capacitors. I could instantly see the markings while they were still in the bag. This would have been great video skit for a "should have gone specsavers" advert.

[@TheSpotify95]

From the CZB listing for the clock: Battery: LR1130 (For Safe Shipping，battery not included) Looks like it is an AG10 then (AG10 is the same as 1130)

[@johncook5872]

Julian, You bought the E6 series resistor pack. There are E12 and E24 packs available.

[@karl9460]

Those actually seem like the best "cheap" breadboards you have tried to date.

[@angelioto007]

Hey Julian, here's a little trick for ebay links. You might be aware that the listings reappear, even when ebay doesn't want to point you to those listings after that long time and instead the "view similar items" appears. Well what you can do is use this: www.ebay.com/itm/*the number of the listing* For me it worked every time if i need the same thing i bought in the past.

[@californiakayaker]

Old video, and I bought my assortments back in these days or earlier. I also picked up an assortment or two of Low ohm but Higher wattage resistors. Caps and other things also, all stored in a reasonably organized system. Now to stop watching so many videos and start building and finishing more projects.....

[@bluedeath996]

On the timer, press both the minutes and secs at the same time to reset it to 0.

[@wrqnine7675]

Dark blue resisters are hard to tell colors on!

[@BrianLough]

Those blue resistors are so hard to read the values on!

[@PhilXavierSierraJones]

Press both minute and second buttons to reset!

[@JulianIlett]

I should have read the 'manual' :)

[@PhilXavierSierraJones]

Julian Ilett Those things used to have a little additional printing below the buttons, but looks like those guys went absolute bottom price route and omitted them altogether.

[@RWBHere]

Does pressing and holding the Start/Stop button zero the counter, Julian? Thanks for the video.

[@JulianIlett]

Pressing min and sec together does it :)

[@squalazzo]

that cooking timer is very sensitive to moisture/water vapours and tend to flicker/halt... have to be sealed some way before putting near the kitchen furnitures...

[@prob17]

Julian I am interested in the power supply - can you please share a link?

[@Darool]

Those caps do say it ;) look at the solderlips, one is an minus, and one is an plus ;)

[@JulianIlett]

Oh yeah, that's totally cool :)

[@videolabguy]

Sorry. Did not see you beat me to it.

[@Darool]

Not a problem :)

[@patrikmckane4903]

What is the power supply you are using?

[@ShaneMatthews27]

Wow, are we really at postbag number 104? I remember when you decided to start the postbag series, number 1. I guess I've been subscribed for a while.

[@joshuabest100]

I bought a pack of those resistor packs and it never came with a sheet or marking so i had to go through them and messure them all

[@anvz6]

Try pressing min and sec buttons at the same time un the timer.

[@DAVIDGREGORYKERR]

I am sure a vocoder could be implemented using DSP hardware and the vocoder software in EEPROM using Pure-Data or using some sort of I/O ADC/DAC interface board that would connect to the Raspberry Pi which would run Raspbian Jessie and Pure-Data.

[@JulianIlett]

You can probably get a vocoder plug-in for a free synthesiser app on your phone :)

[@jlucasound]

It's for cooking (countdown). It is not a stopwatch (time lapse). Would have been nice, though, if it had that feature. Did I comment too soon? :-)

[@Anvilshock]

Eh, Julian, I just look for the offers with the highest n for "n values m pcs metal resistors". Found a 135-value one, and in comparison with other offers (120 values, 130 values, 134 values, etc) they all only differ in very few obscure values in randomly selected powers of 10, like 8.4 ohms or something like that, and about getting one bag of each, I think I'm settled for life as far as selection goes. I don't think I'll ever have an application that necessitates deciding for a 1.1-ohm over a 1.2-ohm through-hole resistor, but alas, I have them now. Assortments are just too attractive to not have.

[@BrokenVideoProductions]

I find these transparent breadboards reasonably good compared to the awful cheap white ones. Do anyone know where to find high quality breadboards?

[@ParedCheese]

I think the breadboards clip together with a dovetail joint, don't they? You need to *slide* them up (or down) to detach them, not bend them sideways? I suspect you may have squished the plastic a bit on the slidey slots. 😶

[@JulianIlett]

Not squished so much as cracked/splintered :/

[@km5405]

they slide up and down yeah ... its a pain to cut away at the adhesive backing though.

[@karlng2691]

Julian, when will you continue your Vocoder project?

[@JulianIlett]

When the nights draw in :)

[@kirash4]

The capacitors are labeled. Look at the tabs and you'll see that on one side the indentation on the tab is a cross shape and on the other side it's just a negative (bar) shape.

[@JulianIlett]

He he, I couldn't see the wood for the trees :)

[@kewakl8891]

Yeah, those stampings are crap. would it be so difficult to make a SIMPLE *+* and *-* not a 4-5mm pattern.?

[@kirash4]

Yeah, you'd think so. They're cutting corners everywhere. Pretty soon there won't be any markings at all.

[@geralteld1332]

*labelled

[@kirash4]

Both are correct spelling.

[@lezbriddon]

whenever i get the resistor packs they print on them in almost invisible ink...

[@lookitsahorner]

10:32 did he get zapped by that cap?

[@nutsnproud6932]

Press MIN and SEC together to reset.

[@experiencingtechnicaldiffi5184]

At 14:34 when you started the timer it was counting up because it was started from zero. It will go to 99m99s. When you set a time then it counts down to zero, alarm, doomsday, danger Will Robinson. I got mine from the dollar store for...A Dollar! And it has a battery. And it's pertier what with colored stripes and whatnot. I feel so blessed. Or privileged. Or lucky. Or not, because most stuff I get off of ebay seems to get lost and they have to resend it. Most irritating, Cheerios.

[@TKomoski]

The vocoder? Yes i see you're getting the parts cool. Still any eta on it.

[@TheSaabClinicUK]

re: Timer. Press Min and Sec together to reset to 0.

[@jayherde0]

Yup .. knob goes all the way to 11 ;-)

[@priestland1]

What I find so amazing about these items from China is the price. How can they manufacture, then sell for such a low price and still make a profit.

[@NoName-bt3oy]

There are generally all substandard. OK for farting about with, but not for any real application.

[@bobriemersma]

Stolen IP, slave labor, nuclear power, massive pollution, no safety regulations, poison-spouting diesel transport, etc.

[@Zadster]

Also a massively skewed exchange rate, fixed by the Chinese government.

[@JulianIlett]

Coal-fired power stations are cheap to build and run, so China becomes wealthy. This has enabled massive investment in their solar industry, so China can lead the clean energy revolution. Pollute first, then clean it up afterwards.

[@NoName-bt3oy]

Indeed those apply, but my point should stand out, especially wrt to an electronics channel. I reiterate: These parts are OK for farting about with, but do not use them in any critical applications. Do not use them for repairs either. Look at some of the shit that Julian has had on his channel. Even a simple thing as the tip cleaner was a bogus camouflaged steel one.

[@drewduncan5774]

It is centered. It just goes to 11.

[@JulianIlett]

:)

[@R4MP4G3RXD]

Julian, why don't you make kit build videos, and use them as your vlog?

[@JulianIlett]

+R4MP4G3RXD I'm thinking of doing live stream kit builds 😀

[@robfenwitch7403]

My timer is cleared by pressing both minutes and seconds. Of course, you could have read the manual where is say just that.

[@JulianIlett]

Yeah, I didn't RTFM :)

[@ccdimage]

Scrolling the video back to 13:40 is an interactive fun for the audience feature.

[@maicod]

timed almost bang on :D

[@acgandhi]

I plotted the resistor kit vales on a log scale. Seems there are weird gaps with both series. docs.google.com/spreadsheets/d/1nKoNJn5b-hJuOC4Gr5p9Xa2M9MJZUXZf_llWCQ-tZeA/edit?usp=sharing (blue is the smaller kit, red is larger).

[@JulianIlett]

Oh wow - there really are some gaps. Thanks so much for doing that :)

[@martin.pokorny]

15:04 ... if your name is Ahmed Mohamed, please do not bring this timer to school. You could say "this is just a timer" 53x, but ...

[@YourMotherSucksCocksInHell]

... and then demand $15 million, sue several media outlets and move to Qatar.

[@DoRC]

Plus and minus are stamped on the tabs

[@JayGee6996]

How come you use ebay.com and not ebay.co.uk? Some of the products you link to are cheaper and quicker delivery from the uk store.

[@JulianIlett]

My Paypal funds are mostly in US dollars. Also, in terms of viewers, the USA has the largest share.

[@JayGee6996]

Julian Ilett Makes sense now 👍

[@tmdcbass]

Stuff! My favourite :)

[@1914grant]

We`re Just Getting The Dross hahahahah Looks Like They Have Cherry Picked hahaha

[@jayherde0]

The breadboard power rails look like a bunch of 5 connector pieces. That would also be very annoying :-(

[@lezbriddon]

these are the chines sellers who are sticking to the rules and not sending lithium batteries through the post... err no, these are the sellers saving a bit on batteries, they are allowed to send lithium into the uk post /if/ the battery is inside a product

[@Kondzio29]

postbag with vlog ? PostVlag? :D

[@JulianIlett]

Hmm, Vlogbag maybe :)

[@grandadie]

VlostPaogB

[@yankozlatanov]

From this video kzbin.info/www/bejne/e3y1i3iZYpmGeNE i have calculated ~0.5 to ~0.6 farads for the supper capacitor (from 0v to 5v for ~30sec of charging @ 100ma) is that right ?

[@sharpeyedwatcher9724]

Julian metal film resistors are all 1%+/_.

[@bobriemersma]

Um... aren't those solderless breadboard bits supposed to "slide lock" together rather than ripping apart/ramming together? I just cringe every time I watch this.

[@JulianIlett]

It seems the transparent ones are slide only - the white ones are slide or snap :)

[@PaulJosephdeWerk]

All my white ones are slide lock. Just because the white plastic is more forgiving to snapping apart/together doesn't mean that is the proper mating method. If you look carefully, the male portion is a trapezoid, and snapping them will eventually wear away the points that hold it to the female side.

[@JulianIlett]

The 400 point breadboards have a cylindrical locking pin - a little more forgiving than the 800 point dovetails. Regardless, I like to use a variety of different mating methods ;)

[@soarer282]

I think we could all use a variety of different mating methods

[@creativevillagetv709]

Good videos (Y)

[@sharpeyedwatcher9724]

Press min and sec buttons together to zero.

[@ollieb9875]

Oh.. heck. 😂😂

[@mrlithium69]

Why arent chinese sellers allowed to ship lithium batteries over the post ? How can ebay 18650s be sold at all.

[@TKomoski]

THe work

[@tiger12506]

I cringe every time you force breadboard rails apart and together. Form implies function, and they all are designed to be attached and removed by sliding. Love your videos, I watch them all the time!

[@JulianIlett]

+tiger12506 I secretly enjoy making people cringe 😀

[@DigBipper188]

You could call it "Julian's VLOGBag" ;)

[@waltstorey]

Hi Julian, I have some ideas I'd like to run by you.. Is there anyway I can get in touch?Cheers

[@gapadad2]

it was counting up the first time you pressed start

[@ismzaxxon]

Not sure about the rest of you, but i came here for the arduino projects. Post bags everyone is doing is not novel any more. What happened to the solar mppt project. Volume is having priority over interest :)

[@tonysansom]

Terry Peake You came to a video entitled "Julian's Postbag #104..." to see Arduino projects and then complain it is a postbag video? Very strange!

[@brit1066]

Julian, love your videos.However as a Brit who has lived in the USA for nearly 50 years, I would recommend that ocaisionaly you should call these videos MAIL BAG, just in case the cousins get confused.

[@Zadster]

Are there many Americans who are unable to work out that a postbag is a mailbag? I'm fairly sure that sort of person wouldn't be interested in these videos.

[@SproutyPottedPlant]

Zadster it always goes the other way, Americans making videos for Americans, Brits making videos for Americans, Aussies making videos for Americans, calling torches flashlights, saying sidewalk instead of pavement and the worst is calling a Megadrive a Genesis!

[@robfenwitch7403]

What does the 'P' in 'USPS' stand for?

[@shiladityaray92]

9 dislikes for what??

[@iceberg789]

jealousy

Im not trying to troll or anything but there is nothing more boring than resisters they are simple, ppl like gadgets and other components but resisters are basic!

[@ortzinator]

Jay Mee His postbag videos are like a buyer's guide for me. And it's not like he spent 10 minutes on it.

resisters in every other video bores me quite alot lol i don't mind variable resisters

[@jort93z]

those resistor sets on ebay are really dirt cheap. i think i got 600 for 3$ or so.
