mailbag Monday 137

[@AnotherMaker]

Mailbag Monday starting with Grandpa's Sweater is one of those things that makes everything seem right in the world. Brings me back to the good old days of electronics in 2019. Very nice haul as usual. Excited to see what you do with that LED panel.

[@GnuReligion]

Now I wanna try a Grandpa's Sweater. Hope that pileofstuff is getting compensation!

The thing with the USB-C thing is that this one likely is just a pass through for phones that still have an internal DAC which is why it is so cheap. Certainly at the beginning of the crusade against 3.5mm manufactures kept the hardware internally but just routed the audio signal over the USB-C port and provided a cheap adapter. For Samsung phones it is possible you need a slightly more expensive dongle one with DAC build in. Generally speaking the ones with a DAC in start somewhere around 10 euros on amazon (no idea what the going rates or on Ebay in Canada though).

[@pileofstuff]

That sounds likely. I'll have to try a few other phones

[@crayzeape2230]

I'd say it's a standard USB sound chip and the phone just lacks a kernel driver. The ad said it had PC support, and the price matches that of a standard PC 'USB sound card' on Aliexpress.

[@crayzeape2230]

@@pileofstuff I just found a bunch of youtube videos showing how to enable USB audio on various android phones, including samsung devices. Enable developer mode (Go to 'About phone' / tap on 'build number' repeatedly until developer mode activates) Go to System/Advanced/Developer Options. In the Media section, turn off 'Disable USB audio routing' Also check 'updates' in the 'galaxy store', depending on your phone there will be a USB-C update for you to install.

@@crayzeape2230 @Cray Ze Ape I bought two different cheapo usb c headphone adapters, and neither works on my Galaxy S22 Ultra. I found those same videos you talked about and made the recommended settings change, but it made no difference - neither adapter works no matter what I try. I don't know if Samsung has screwed up usb audio support, or if the products are pure scams, but either way I'm pissed off that they dropped the jack on new phones. Absolutely no technical reason - pure marketting bullsh*t!

[@crayzeape2230]

@@RottnRobbie Thanks for the info, I'm guessing Samsung may have screwed with things. A quick test on a PC would prove or disprove the "pure scams" idea.

[@frankowalker4662]

I got a BMP280 sensor, but I could never get it to work. I look forward to your video on it. Hopefuly you will have more luck and I can see where I went wrong. :)

[@stevetobias4890]

The example scetch for the LED Panel asks for the number of LEDs high and the number across. After that you play with the code to tell them what you want to do.

[@3ATIVE]

Search my channel for "How to Flash and use WLED firmware on an ESP8266 Sonoff Basic"

[@kyleallred984]

I would test the middle black wire to see if it is mislabeled, with my phone I had a dongle work with my phone for a while but my phone's port got slightly damaged so I can still just not transfer data, oh LEDs excited for the project, and your own version of the capacitors

[@notsure3448]

I bought that same headphone adapter for my pixel and it also didn't work. I found out some phones don't include a DAC in the phone so you need an adapter with a built in DAC. I'm not sure if this is the case for you, but it seems likely. I found a relatively cheap ($5 USD) at a store called 5 Below that worked, basically a slight step up from any of the dollar stores. Checking eBay they do have some with built in DAC for around $5. Hope that helps.

[@doingstuff76]

I bought 2 from ebay that is like a cord splitter but I was so pissed i got the same error code. How do I get it to work?

[@notsure3448]

@@doingstuff76 I think it depends on what phone you have and what adapters you bought. Some phones ship now without the circuitry to convert the audio to analog for the headphones, so you need to buy an adapter with that circuitry built in. I'm not sure what you mean by cord splitter, but if it doesn't have a built in DAC (digital to analog converter) and neither does your phone then it's likely you will keep getting the same error. That's how it was for my pixel 6 pro.

[@RottnRobbie]

I'll be looking forward to the teardown of the usb dongle - I now own two that won't work on my new Samsung phone!

[@michaelkaliski7651]

II bought a USB C headphone adapter for around UK £5 to use with an iPhone. Works as advertised for the headphones but the pass through socket only appears to support charging. Good enough for the money but these devices need to be a lot more complicated internally than just running wires between the connectors. There is some digital processing going on as well.

[@onecircuit-as]

I think the BMP280 is temp/humidity and the BME280 adds air pressure which means you can make an altimeter (if you know current sea level air pressure).

[@ElmerFuddGun]

Actually the BMP280 has pressure and temperature and the BME280 adds humidity to the list.

[@onecircuit-as]

Good pickup - I've used both and knew the BME280 was the preferred option for me given all the measurements.

[@chrisdouglas226]

Awesome - Grandpa's Sweater is back! :) They had an issue with a re-fermentation in the can causing mini explosions. The last time I went into an LC they didn't know when it would be back, so I'm happy to see it.

[@SidneyCritic]

Beer and a breathalyser, and yet no test. Very disappointed - lol -. We used to try and peg the meter on pub machines by gargling vodka, even though we weren't even liquored, ie, alcohol in your mouth will read even though it's not in your bloodstream.

[@TradieTrev]

That flexible led panel I wonder how long it will last?! I would love something similar but with an aluminum substrate to dissipate the heat.

[@DrexProjects]

I had one of those booze samplers ( Still Do ) and it always went into the red. I never tried it sober tho. Which is rare.

[@dennischerry4545]

Keep the brightness around 25-30% on the panel. You do not need 100%.

[@TBL_stevennelson]

I live in brampton didn't know we sold stuff on ebay from here

[@pupplecoffee]

BMP280 need more delays than BME280 for reading sensor values.

[@SimpleTechvn]

Hi friend! Very interesting items! Have a good day!

[@pileofstuff]

Hello. I'm enjoying those free-form circuit projects you are doing.

[@brettb.345]

I like those LEDSs. I made myself a clock with two 4x 8x8 green matrices. This neopixel? version seems to be a better way of doing it.

[@GnuReligion]

It would have been fitting to use the breathalyzer before hooking up the cloned SSR to mains. Have hurt myself and broken things with oh-so-much less power than that ... esp when drunk. (hic)

[@wrxs1781]

We need a workshop tour of everything you have accumulated over the years, must be like an electronics superstore.

[@ronniepirtlejr2606]

They usually have USB adapters at Walmart that are compatible with Samsung/ Android

[@ronm6585]

Thank you.

[@TriggerThat]

See, only a Canadian would call the winter temperature "interesting" when its -26 outside ;)

[@OutdoorsWithShawn]

That's the issue I have with my Galaxy S21 Ultra. No headphone jack. I don't own a pair of Bluetooth earbuds, nor do I plan on buying any. I haven't found an inexpensive USBc adapter yet that will work. I have 6 of thr 8 channel SSRs running my Christmas light show running off an Arduino Mega. They haven't let me down yet after 3yrs

[@kjur18]

This led panel is mislabelled. Middle connection should be 5V and Ground, it would be pointless to put Data In there.

[@3ATIVE]

Agreed, that's a 'Power injection' point.

[@pileofstuff]

That makes more sense. I wasnt sure why there wpuld be a data connection there either.

[@fredflintstone1]

yea!!! a mailbag Monday🙂

[@patprop74]

The first item ( USB C to headphones) probably does work, I'm sure it has more to do with the version of android that is preventing it from working so you would be forced to pay 400X more at a cabtel, I am sure someone out there has a version of Android that will let that thing work.

[@pileofstuff]

Interesting. I'll have to try it on a few other phones

[@aryeguetta8592]

There is a NOT Cheap solution for the LED Matrix that you can try but it is 30$ - K-1000C is a good controller. You might also try the WLED if that can do any help :)

[@mad_circuits]

Nice video, thank you! But if you don‘t wanna burn down your house, you shouldn‘t operate noname relays at mains voltage. 😉

[@keithwebb9768]

The USB-C headphone thingy, did you try it other way around? i.e with headhone socket on the right.

For the LED Matrix, try WLED. Here's a tutorial I made using a Sonoff Basic (ESP8266) - kzbin.info/www/bejne/poC6Ymqqo657m68
