@51:45- HEY - NOVUS! My first calculator! Part of my The First Light Emitting Diodes Vlog! I still use it too....

[@FranLab]

Fran Blanche ...And no debouncing, so quick on the switches!

[@LasseHuhtala]

Fran Blanche My TI-30 likes to repeat numbers too, but I'm not sure if it's a debouncing issue or just a dirt and cruft issue. ^^

[@proyectosledar]

excellent video Dave. I agree with you, those leds (5050 or 5060) are 60mA.

[@davidriley7659]

I can see a static decimal point calculator being useful in some situations. I'd want a '00' key though

[@Antiath]

Man, I really miss fundamental fridays and similar technical videos.

[@EEVblog]

Antiath I just did one last week!

[@Antiath]

EEVblog Yes and I really appreciated this one. I didn't count the frequency of those type of videos but I get the feeling that they are less and less frequent. I only subscribed a year ago, so I may also be a bit biased.

[@maximilianmustermann8172]

EEVblog Time appears to slow down :D

[@CPZeroDue]

About the LED stuff. Poor thermal design makes temperature increase too much. This leads in VF of leds dropping, maybe by 3-4% for those LEDs at 70°C. Rectification diodes also drop VF. That leads to an increase of current since resistors are fixed. Another point is: you supply 12V from a bench PS, maybe the PS used to turn on those LEDs has higher voltage even staying in the declared tolerance. Looking at the datasheet I also see the VF of those LEDs can change by 0.7 volt between opposite bins but I hope at least they selected the right LEDs for that design.

[@CPZeroDue]

CPZeroDue forgot the conclusion :) the more the heat, the more the current and the drop on resistors that go out of spec (besides derating with temperature). And a higher than 12V supply increases the problem

[@optroncordian7863]

The connector on this bulb suggests that it will mostly be used in automotive applications. The fact that an ordinary car alternator keeps voltage as high as 15 volts just makes thing worse!

[@Tangobaldy]

Modem noise eeeek! I had forgotten about that. I used to put tape over the speaker or stab it with a screwdriver.

[@mpy1202]

Thanks Dave, don't know why but this mail bag felt like one of the best I've seen from you. Must have something right! Enjoy the view looking forward to that bug sweeper teardown.

The iiNet modem brings back memories. I was one of the initial beta testers of that device, I had one of the non-wifi models. All of the beta units had a USB port which didn't actually do anything and couldn't be firmware upgraded due to some changes in the new firmware. When the beta period ended we had to ring them up and they sent us out the production units free of charge. Still have that modem kicking around as a spare.

[@hopkinskong]

27:43 Should be CSR.

[@williamhayden7711]

Big thumbs up for the mini-troubleshooting segment in this mailbag!

[@dumeinar]

Best mailbag in a long time. Swedish stuff, spy gear, weird parachuting electronics. Only thing missing was one or two more quick teardowns.

[@kruppin]

The burnt up leds are probably more because the original driver in the light fitting was made for halogen lamp at much higher watt, so the voltage is probably more like 16v when using it with leds. You almost always need to change the driver as well when changing to simple resistor dropper leds like these.

[@ScottHenion]

Those LED boards usually don't consider use in automotive applications. At 13.8 or 14.4V they will definitely cook ;)

[@douro20]

Scott Henion Yep. Gotta have a good regulated supply for them to work properly. It may be a good idea to put a 7812 in line with one.

[@akhurash]

Scott Henion Also I would think transients would be bad for them.

[@douro20]

On a separate heatsink.

[@szyszaszy]

douro20 See dropout characteristic of 7812. For 13.8-14.4V range it will never act as a regulator. You should consider using LDO regulator instead (that would still be an overkill here, though).

[@dumbo800]

Scott Henion My thoughts, as well. I saw that connector and immediately thought they are just cooking that board inside of a domelight enclosure. 14VDC plus transients, probably aging alternators pushing significant AC through, too.

[@CarstenBauer]

[@Mostlyharmless1985]

Ultrathin and tablet type PCs aren't terribly easy to disassemble if you are uninitiated. Check iFixit and see if someone ventured before you to get a tear down. Sometimes the service manuals are leaked online that shows the breakdown procedure, and SOMETIMES the company doesn't have their head up their asses, and give access to to the end user for how to break down their product line. Barring that they are almost always press fitted and you need to use a silicon spudge tool to separate the piece far enough to wedge a guitar pick in, and then you can roll the guitar pick around to complete the separation. It's super important to check for any screws that are holding the screen in place first.

[@NeoNick5435]

That "proprietary" connector is actually a PDMI connector, which was a (failed) attempt at a new standard device connector.

[@JulianCalaby]

Nick5435 It doesn't make it any less of a pain in the ass when you want to get a replacement for them. (Cheap ones on eBay last my partner about a month a pop, an official Asus one is over $30 each.)

[@Razor2048]

The tablet is annoying to open since they like gluing everything, but there are teardown tutorials. There is a risk of cracking the screen during the teardown, as it has to be pried off.

[@EEVblog]

Razor2048 Thanks for the heads-up.

[@CarstenBauer]

Razor2048 Just pry off the edges of the tablet.. very simple. Nothing was glued on mine.

[@TheShivABC]

I love your vids Dave but where are the teardowns, the mailbag segment is fantastic but you haven't done a tear down Tuesday in quite some time

[@EEVblog]

Mike Fish I know, I've got a few big ones coming up. And by big I mean it can't fit in the lab, will have to tear down in the bunker.

It would be glorious to let us hear a sample of that cassette in the teardown!

[@BenjaminEsposti]

40:39 .... You should have smelled the inside of an electronic florescent ballast I tore down after it failed. It had significant arcing damage on the output (lamp) side. Smelled so horrible! Also, almost all the components were covered in a layer of soot. I've torn down similar models as well, and they all have the same failure ... I think it initiates from bad solder joints, as there are cracked solder joints all over the place! At least the ballast has a metal case ... not flammable plastic.

[@SomeMorganSomewhere]

The tablet will not charge from 5V, whilst it appears to be a "standard" USB connector, there are "special" contacts buried in there which take, I think 15V from a "special" Asus charger.

[@SomeMorganSomewhere]

OK, apparently that version WILL charge, likely very slowly from 5V USB, must've been an upgrade from the original versions.

[@JerichoKru]

The back cover is clipped on the tablet (Transformer TF300T, I think). You need something flat to run along the seam. As for getting it working, a simple re-flash (assuming the chips are still good) may revive it. There should be a few guides out there to do it.

[@frollard]

That's an ASUS Transformer...not sure of the generation based on the colour; looks like a TF201; tegra 2 processor Edit: Reason for the stupid proprietary cable: When it handshakes between the charger and the tablet it boosts up to 15V2A mode to provide significantly more power than a standard usb charger. Edit-2: the proprietary connector is also so there is a more robust connection between the keyboard (batterY) and the tablet; it's semi-mechanical at that size where as if they used mini-usb aligning it would be a pain in the ass.

[@xXMrGameProXx]

frollard I think it's not only an ASUS connector. There's one of these on my Samsung Tablet. I think it is called PDMI (Portbale Digital Media Interface)

[@frollard]

ablackack That one is sadly proprietary to ASUS...samsung has ANOTHER stupid connector. (have them both)

[@xXMrGameProXx]

frollard Ahh. OK. I didn't know this. Looked exactly the same

[@sarowie]

frollard Dave asked for a secondary charger connector like mini or micro usb additionally to the asus connector. Or just the got old barrel connector. Dave would had been happy with the asus connector + standard connector. I mean: As a system engineer he should know that this as cost to the BOM, that the user will plug two barely specified chargers in at the same time etc. but then again: Carrying a set of cables can not be the best solution to this problem. (But then again: A few years ago, we had to carry one wall wart with 50/60 Hz transformer around for each and every device - using USB on the charger side of the cable is quite some progress)

[@fuzzy1dk]

CSR "Cambridge Silicon Radio" is one of the really big players in Bluetooth

[@aserta]

There was a method where you'd turn off all power at the breaker box and then you'd use one of those probes for electric circuit analysis, can't remember exactly what the trick was. Supposedly you could do the detection on the cheap.

[@kristina80ification]

Is there any chance that you will rip the tape for the bug sweeper? Might sound strange, but I would love to hear it.

[@Graham_Langley]

Re. the Raspberry Pi I/O Hat, I'd add that that PCB makers don't like indent ink being screened over holes/vias as it forms a blob on the underside of the screen and ends up making a mess on a PCB, which then has to be cleaned up.

[@0815mkl]

Using a bridge rectifier will also increase the voltage of the DC output by a small factor. So thing should go even more worse for the LEDs. I think there are a lot of small things come together for these cheap produced lamps to go off like wrong connected capacitor.

[@jamesingham]

Dave, if you fancy turning that Cypres on at some point, press the red button and then wait for the LED to turn on. Then press the button again, wait for the LED. Etc. After 3 times it does a init seq.

[@vasfed]

About the LED - it might have been run from a 12v ac, with 17v peaks and lots of flicker

[@alison_withonel]

CSR on the bluetooth headphone adapter would be Cambridge Silicon Radio. They're a huge manufacturer of Bluetooth chips.

[@dorbie]

It's a Cypres 2. So it is a newer version. That is an expert version it will fire at 750 ft. It opens the reserve. I have not seen the other teardown :-)

[@letsnotplaywithelectricity9346]

EEVblog Good to hear! Can't have anything getting in the way of Teardown Tuesday!!

[@SeaGuy100]

If you pop one of these LED replacement lamps into an older fixture that was designed for a halogen bulb, that fixture can drive the lamp at much more than the nominal 12 volts. Halogen fixtures often have a completely unregulated AC power supply (just a transformer) sized so that it will provide a nominal 12 volts into a 20 watt (or 50 watt) load. But that transformer might provide 16 volts into the much smaller load of an LED lamp, because there will be far less resistive loss in the transformer’s secondary winding. Since the LEDs themselves are constant voltage devices, all of the extra voltage will appear across the dropping resistor, so at 16v minus 9v for the three LEDs in series that’s 7 volts across the resistor. 7 volts squared / 91 ohms = 0.5 watts. Now we see why those resistors might overheat.

[@GR1NREAP3R]

The Galaxy Tab 2 also use an ipod like charge cord.

[@pocoapoco2]

I wish I could find the calculator my parents had growing up so I could send it to you. It was a large four-banger as you say. It had a Montgomery Wards badge on. I'm not sure who actually made it, but it was the only calculator I have ever seen that had a segmented display that used an incandescent bulb as a back light to make the characters visible. I wonder if you have ever seen a display like that before.

[@mattsains]

Omg, I have a very similar HP convertable tablet, also with a apple-looking proprietary connector. Been looking for a connector to USB forever, but HP pretends it doesn't exist. Wonder if they're the same connector?

[@adamlumpkins2000]

Dave you don't think that it was a power surge that got those leds?

[@TheOriginalEviltech]

I have a wifi router hacked to incorporate a microphone and transmit both trough VoIP and separate 5GHz wifi network. Both are accessible trough the router's setup website. It has a hidden button on the site that opens the options for the microphone. It's a TP-Link branded one. Looks like it's an original one hacked to do more stuff.

That device at around 34 minutes - FRAD as we know em here in the U.S. Frame Relay Access Device.

[@eternialogic]

Its disgusting to see people using resistor dividers when a voltage regulator is required for a 15W LED light. In my University, most new people in Project Lab 1(Out of 5 project labs) the groups tend to use resistor dividers instead of voltage regulators AND optocouplers. We go through digilent Basys2 boards like candy because they do not protect the Basys2 boards, which do not seem to have any good input protection for the FPGA. The cost at the end of each semester tends to be close to $2500 to $5000 because people do not protect their FPGAs. A lot of graduates from India come to Texas Tech with no prior practical experience and I've seen them use breadboards in a microwave project. When you ask them what a simple component is, they are flabbergasted, which is why undergraduates run the stockroom, not graduates.

[@agonymobile]

For the LEDs its for a car which might get 14volts when a car is running or battery on charge, imagine the current and the heat generated in 14 volts instead in this case, surely will exceed 70c by far.

Whats that weird sound from 36:33 to 36:40???

[@nplanel]

EEVblog : (LED bulb) I'm pretty sure that was plugged over 12V AC so it's not the same .... As you known, this will raise the current to ~75mA peak (25% over current @100Hz)

[@ethanpoole3443]

If they are run on 12VAC (RMS) then they will only have a short period of conduction on each cycle when the voltage actually exceeds the forward drop of the 5 series diodes (2 in bridge plus 3 LEDs) that make up each string (with 9 sets of LED strings in parallel). So, while their will be greater peak current draw there will also be considerable periods with little to no current draw (as there are no filter capacitors to smooth things over). Besides, 12VACrms will still have the same average forward power as 12VDC to the extent that the load appears resistive (not perfectly resistive, but largely so). Regardless, it was still lousy thermal design -- all that room on the board for large copper fills and they wasted it all by etching nearly all the copper away, losing a good heatsink in the process! Copper fills on a PCB can dissipate a good deal of heat when properly exploited (plus it is otherwise free surface area).

[@nplanel]

Ethan Poole You seems to think you signal is still a sinus, it's not anymore due to the bridge rectifier. So 12 VAC RMS is not what the LED + resistor dissipate, it's a lot more when the current is rectified.

[@alison_withonel]

Under the heatsink of the wireless router, it's probably not a custom ASIC. I'd guess it is a standard ARM or MIPS SoC from Marvell or Atheros or Broadcom. Most of those routers run Linux or VxWorks.

[@ethanpoole3443]

That would be my expectation too. The bandwidth on these devices isn't all that great to begin with so little need for high performance Ethernet frame switching and routing ASICs, they would get a much greater boost from an ASIC that accelerates encrypting and decrypting the packets.

[@FormerMazda]

[@Nordic_Mechanic]

9:42 Knowing it was specifically used by and designed for the same gov who said it's in violation of federal laws, that make a pretty good example of double standards

[@ethanpoole3443]

The warning related to using the technology to try and conceal an illicit listening device. It is perfectly legal to use such a device to detect and locate listening devices within your private property (or otherwise private space, such as a hotel room or office). That said, intentional eavesdropping is perfectly legal in some states provided that there is at least one party (to the conversation) consenting to such recording. In other states all may need to consent. Regardless, such is potentially legal in public areas if there is no reasonable expectation of privacy. And, of course, listening devices are perfectly legal if there is a court order authorizing their use for evidence gathering. But when it rises to the level of nation state sponsored espionage then all is out the window as most every nation state spies on the next, and that is often not such a bad thing as spying has often made all the difference between nations going to war over misunderstandings of intent versus seeking a more peaceful diplomatic solution.

Well,now,that's interesting. I recall seeing a cassette with a very similar label,in my childhood. I vaguely recall seeing one of those plug-pack sensor/probe things too. That Asus thing is weird. "TekThing" just showed this in a recent episode. Really goofy charging and stuff.

[@Mostlyharmless1985]

Those connectors aren't proprietary. Its a 30 pin data connector. Apple chose to do it with their tablets and iPods to keep the port end agnostic to the standard it was connected to, because back in the day it could have been connected to firewire, or USB. Also, USB sucks sucks sucks. At least until the 4.0 standard comes out and we can finally get plugs that can be reversed.

[@gigabytex64]

there will be a way of charging the tablet and the keyboard dock has its own charger and is supposed to boot the running time on the tablet itselfe.

Hey! I think I know why you weren't finding a problem with the light. You're running under the assumption that the power going into them is actually 12v. I would put $5 down that whatever was feeding those lights were actually well over 12v or possibly even 12v AC. If those lights were run on a slightly over voltage power supply the problem would escalate quite quickly.
