Hey Dave, Just a message to send my thanks yet again for inspiring me, you may have noticed me arse licking earlier. Its because you have truly made a difference. Though I spent much time running a service dept I never had much time to dabble in design, I enjoy your exploits and enthusiasm and humor so much I am now having ideas popping out all over. I think you are becoming a really important cog in the mechanism that speaks to those who will become the next generation of engineers and I am sure you will inspire them maybe more than me who is an oldie having a second bat. That and RUclips becoming I think the premier medium for communication of this sort. Well done and thanks from a pommie. I will get a beer later and think of you as I pour it down the sink.
I was still using an 8060 just a few years ago when I needed another meter during testing. Nobody had the will to get rid of it and we made the company pay for calibration each year and she got it done. Sadly about 2 years ago she finally went down and we keep her in a display case now.
Your enthusiasm, knowledge and simply having fun is what keeps me coming back to view. Used to clean Nortel/Avaya 2xxx and 3xxx series phones with iso alcohol-nice choice for cleaning crusty plastic. Cheap and effective. Cheers!
I still have my first multimeter - the Fluke 8020B, purchased new around 1980-1981, and it is still just as accurate as the day I purchased it. While I have several other newer, more fully-featured meters, I still regularly use my 8020B. I even still have the original case and leads, all of which are in good to great condition. Long live Fluke!
+EEVblog - the laser pickup at 48:37 looks similar to the type used in the Nintendo Game Cube, and in a fair few car DVD players / laptop DVD drives. The Game Cube one looks like a Panasonic HUL7208, which they call a "Hologram Unit"... www.datasheetcatalog.com/datasheets_pdf/H/U/L/7/HUL7207.shtml The laser is side-emitting, as you say, and the photo sensors are underneath the prism block. It's a nice way of making a more compact laser sled, as it doesn't require a separate "port" on the sled for the photo sensor array. I'm not sure exactly which type you have there, but it looks like it could be a high-powered diode from a DVD burner / recorder maybe?
I also have the ELM 327 adapter and it works great. You have to hook it up correctly though. I use an app called Torque. You have to manually pair it, but then it connects automatically.
Hi Dave, the Port on the PowerBook is for external SCSI devices. Also, Balls are fine 😊 The Power button was rarely used, the PowerBook got into deep sleep when closing the lid, and wakes up when you open it. Looking forward to the tear down 😊
I'm just about the opposite of an Apple fan, but I was fascinated by the laptop. Man, the effort it took to develop an OS for 68k back then was heroic. The old tools and severely limited access to information (no internet!) would have made it incredibly difficult. I have a lot of respect for guys that did that work so long ago.
Dave, the bluetooth car interface won't work because it is from the northern hemisphere. You have to reverse the polarity for those of us here in the southern hemisphere. I thought that you knew that the electrons go the other way down here....
Wow Dave now I want that Fluke as well might be old but wow still going strong with accuracy. :) And wow it did clean up nice with that little bit of cleaning on the side with the alcohol. :)
I think the first time that I went on the internet was on a mac laptop very much like that. Some small business people brought one by in the early 90's and let us borrow it for a couple of days along with an account to login to the primitive net. All we really tried was Gopher and Email IIRC, purely text based interface. This was somewhat impressive back when all we had was things like Marmot and BBS systems with QWK and Fidonet networking. A couple of years later I actually went on the net for real with Compuserve and primitive Mosaic web browser.
I've had several of those clear blue ELM327 knockoffs arrive dead. Every single one of them had cracked/bridged solder joints, so I managed to fix all but one. Torque seems to be the nicest Android app for the purpose.
26:34 - Lettraset? wow Ian must have the patience of a clockmaker. For my "neat" jobs I attach insulation tape (yellow) and write on with a black Sharpie or Staedtler Permanent Lumocolor Fine. Nice and rough, matches my demeanor ;) Ian's project is extremely neat, nice work, very slick - reminds me of the GND guys on the key ;)
Dave, I've recently dissembled similar ELM327 dongle (was going to decap that PIC chip you've talked about), and there was none. Apparently it now got integrated into more complex SoC.
You've just reminded me that I've got a Fluke 8020A with the usual failed display. I wonder if anyone's come up with a fix/replacement since I last Googled it.
That's a £50 meter you've go there dave! And that's importing from America as well... wow. My father had one, but he left it in his van during one amazingly cold Yorkshire winter and the display broke down.
A huge number of those cheap OBD adapters use counterfeit ELM327 chips. I had a similar looking one with the blue case and it didn't work for me either.
+Wyvrn Yep there are alot of iffy OBD apaters, some of them with certain mac addresses are known to be problematic. there have also been isolated cases where the adapter has damaged ECU's I have one which only cost £12 but it works fine. connects to my peogot 307 2.0 hdi. Havnt used it in a while but there was alot of sensors not supported at the time. They are really handy for tracing minor issues, like if the EML is triggered by something easily fixed, like a faulty MAF sensor. Replace the maf and clear fault codes, No more EML . Getting your car diagnosed for something really simply can be costly.
The story was that the rev1 ELM327 dongles were shipped WITHOUT firmware protection enabled on the micro - so they were quickly cloned by other manufacturers. Versions since then have been protected, and updates are restricted, so the clones are limited to running V1.00 of the ELM firmware, which has support for a far more limited set of interfaces and vehicles.
The tiny DVD head shown at the end of this video gave me an idea that led, (no pun) to repairing a failing portable CD player, an Audio Solutions ATC 351, I bought 11 years ago. Now, I don't have an electronics lab and don't go anywhere near a soldering iron because of very poor vision, but I enjoy your videos very much because they illustrate sound trouble shooting skills anyone should be aware of. I did software support in Silicon Valley about ten years ago. Anyway, seeing that little ribbon cable coming off that head gave me an idea. I went and got a none too small flat head screwdriver and gently pushed on the connectors for the ribbon cables that connect to the laser read head and the main board, after making sure that the batteries were out, you don't want to go looking at a laser, when you can't see the radiation, with a magnifying glass, especially if you only have one good eye. The darned player works now, the ribbon cable has come unseated after ten years jostling around. I really enjoy the who done it character of your videos.Keep up the great work.
I neglected to give all the trouble shooting steps. The CD player would power, write to the LCD display, but come up with "Bad Disc" or "no Disc" and click a couple of times. That suggested that either the tracking failed or the laser diode was out. Seeing your video suggested that a third possibility was the ribbon connector had worked loose, since the failure had ben intermittent.
24:24 Yepp, that´s what Tartan does to you. There are otherwise decent people running around in the open lanscape where Tartan was invented, and whenever they wear it, they start throwing trees an rocks and all sorts of horseplay.
About the old Macintosh laptop. I think that this was definitely during the era of Jobs. We outfitted our engineers with these as the process was Motorola and so were we. The trackball would get crusty inside but was easily removeable (turn the ring 90 degrees). Hey, it wasn't clunky! Nooooo. The original Apple portable ... now THAT was clunky. Yes, I even carried that beast onto an airplane!
A lot of people have trouble with the cheap OBD bluetooth adapters apparently. When I was reading up on them, many people recommended staying away and sticking with the OBDLink devices.I have an OBDLink LX as well and it works quite well. Fun fact about the OBDLink LX on the Toyota GT86/Scion FRS: The computer is finicky about things reading from it while starting the engine. I have to make sure my phone is not running any OBD apps while starting, else it will cause the computer to freak out, throw codes, and not allow things to function properly. Another fun fact about this car: It has 2 fuel rails. I have not found an app that works properly on this car when reading fuel rates, mileage, etc. I think it only reads the low pressure rail. It grossly overestimates fuel mileage (pretty sure I'm not getting nearly 40 mpg in my tiny little sports car).
+Beau Steward I agree, I had a cheap one, the little blue one with the tab instead of a solid bump on the connector side that looks like eBay item number 290812437816 It would connect to '90s GM VPW but not 2000s, and on a '97 Lumina I could actually kill the engine, or at least reboot the PCM, by trying to read a certain PID with it. I now have the OBDLink MX and it works almost perfectly, but does lock up and has to be power cycled (replugged) occasionally. My interesting story with it is that my '97 1st gen Chrysler LH car (Intrepid) won't connect properly if the throttle is open while moving, IE in park or coasting in drive throttle closed, Android apps connect fine and the Windows program shows 2 ECMs (likely the SBEC and TCM) but throttle open Android connects to the wrong ECU and Windows only shows 1 available, and it has very few active PIDs. Once connected correctly the throttle can be opened without it losing connection, so real-time data does work. Oh and the MX and likely LX has an actual pairing button so the guy in the next car over can't just casually connect to it like with the cheapies.
I got one of them little blue OBD (OBD!) adaptors, and it works just fine with Android. If you have an iPhone you're gonna need a WiFi model for it to work.
I like track balls if they're optical, but if the old school rotary ones always got gummed up with finger grease and dirt.Nipples didn't have that problem, but some didn't have enough analog movement, it was either painfullly slow or too damn fast.
+EEVblog Re the Foscam, can you let us know what the power consumption is? can't find any info on the manufacturers website?? we know you have the technology ;)
Is the car audio thing you've got the one from Belkin? You should look into getting the one The Wirecutter recommends instead. Connects a lot faster, and the audio quality is a lot better.
Careful with this camera now that everyone has seen the QR code on the back of it. It contains the unique identifier that allows remote connection from the internet without port forwarding. Yes, it does have a username and password that you can change but it might also have a backdoor account ;)
Sorry to disappoint you, but Shermer, Illinois doesn't actually exist. The town that was depicted in all those John Hughes movies was mostly a composite of the North Shore suburbs of Chicago, particularly Northbrook.
If someone hasn't already suggested it, you can easily clean keyboards and some plastics in a dishwasher! - Make sure you use a cold wash! Can't guarantee it, but saves that elbow grease! Obviously remove the electrics!
+Radek Wysocki The voltage regulator has a thermistor in it that takes care of it for you. The curve is roughly -30mV per °C for a 12V (6 cell) lead acid battery. IOW drop the temp 33° and you need to raise the charging voltage by 1 volt.
That OBD two is out of date for late models 14 and 2015 they switch to CAN Just another way for dealerships to keep you on your toes .And as far as you not knowing About cars the dealership I had to go to they don't even know how to use a multi meter or know what it was. Funny that was the first thing I had to learn in school.
+Keith Richards The heater keeps the voltage reference at a more constant temperature. The reference is calibrated at that same temperature, so when the device warms up during use, the accuracy is more repeatable. ;) It's quite common to find a TCXO - Temperature Controlled Xtal (crystal) Oscillator in equipment that requires high repeatable accuracy. The frequency of most standard crystal oscillators are fairly temperature dependant once you get down to multiple digits.
Hey Dave, Just a message to send my thanks yet again for inspiring me, you may have noticed me arse licking earlier. Its because you have truly made a difference. Though I spent much time running a service dept I never had much time to dabble in design, I enjoy your exploits and enthusiasm and humor so much I am now having ideas popping out all over. I think you are becoming a really important cog in the mechanism that speaks to those who will become the next generation of engineers and I am sure you will inspire them maybe more than me who is an oldie having a second bat. That and RUclips becoming I think the premier medium for communication of this sort. Well done and thanks from a pommie. I will get a beer later and think of you as I pour it down the sink.

Someday, someone's gonna send you a Batterizer. And it'll be glorious to watch :)
Sadly, it'll be too late to warn people by then.
it's sad to see how a big part of the population lacks common sense.
+Fabianwew That would be be all that marketing wank Dave talks about haha
+Tradie Trev Agreed, but the people who truly believe in marketing tends to be the ones with minimal "common sense"
+Fabianwew This is why engineers suck at selling stuff. They are just way to honest.
+berni8k Agreed. Thats one of the reasons marketing is done in another department.
Lol, "What do you prefer? Nipple or balls?" Dave's funny!!
And later came 'it sucks and blows at the same time' ... that was just too much...
LloydBonafide1 Then why do you watch?
+Effay513 I always knew it as the "clit" mouse not nipple.
+Lemming Yep, also called a Clit in Canada
It's the little red button you play with to make things happen!

+Alan Liefting Damn, plain forget! *facepalm*
aahahhahaha i cant stop laughing
We still use a couple of Fluke 8060a meters in our test department. 30 years of use and all still going.
I believe the laser thing at 48:00 was the laser sensor from a DVD player. It detects the optical data reflected off of the disk from the laser diode.
It's a child's toy, no wonder Dave's having so much trouble. Sagan will love it.
Wow Dave now I want that Fluke as well might be old but wow still going strong with accuracy. :)

Have you ever torn down a Detector coil? Would be interesting to see the measurments and how it works :D

In case no one mentioned it, it was Dave Taylor that designed the 8060. He seems to have fallen silent on the forum, I hope he's ok!

It would seem the rotor on that maglev toy has a critical RPM or two.. I wonder what the balancing tolerance is on something like that.

Hi Dave. I'm using the same ELM327 and the LED is always red , even when phone is connected to it.
I actually have one of those torches. it's actually quite good for a cheap little LED torch.
The Spectrum you had earlier was missing half the parts though, maybe this one is luckier?

Love the QZERTY Mac keyboard
au contraire. PowerBook 165C? Pure FrogDesign gorgeousness... that design was praised for light years around... HOW CAN YOU SAY 'no style'... PFFFT!!
I had one of these mac laptops, or very similar! 2 ni-cad batteries, and no, they didn't last long.
I paid just under £2 for one of those obd devices online and it's brilliant!
I like track balls if they're optical, but if the old school rotary ones always got gummed up with finger grease and dirt.Nipples didn't have that problem, but some didn't have enough analog movement, it was either painfullly slow or too damn fast.

Re the Foscam, can you let us know what the power consumption is? can't find any info on the manufacturers website?? we know you have the technology ;)
Is the car audio thing you've got the one from Belkin? You should look into getting the one The Wirecutter recommends instead. Connects a lot faster, and the audio quality is a lot better.
since that pump sucks and blows you can use the side that blows for an Aquarium air stone. very nice.

hi Dave, I was going through some old projects, I found a uA741TC 8 pin package, and was wondering its use/purpose
Careful with this camera now that everyone has seen the QR code on the back of it. It contains the unique identifier that allows remote connection from the internet without port forwarding. Yes, it does have a username and password that you can change but it might also have a backdoor account ;)
Sorry to disappoint you, but Shermer, Illinois doesn't actually exist. The town that was depicted in all those John Hughes movies was mostly a composite of the North Shore suburbs of Chicago, particularly Northbrook.
The reason that postcard at 0:50 was upside down is because it was sent from the northern hemisphere.
If someone hasn't already suggested it, you can easily clean keyboards and some plastics in a dishwasher! - Make sure you use a cold wash! Can't guarantee it, but saves that elbow grease! Obviously remove the electrics!
oh no i was planning to break into your lab, but now you got a security camera there :(
i love it when you say "to all you aficionado's" haha
What's Sagan doing? taking one component from each drawer and putting it in a random drawer?
LOL! Whole shop: spotless. Phone: complete disaster.
The spinning thing is probably supposed to be powered by light.
Safety-wise, would you trust that 8060a?
I have an 8060 but the movs need replacing. The problem is i cant seem to find axial varistors anywhere. Any suggestions?
your alternator is due for replacement if battery voltage reads below 14.2v while running
+Radek Wysocki NipponDenso alternators run at 13.5V. densoautoparts.com/alternators
Thats real wierd, always asumed batteries needed 14.2 to fully charge their capacity
+sivalley Yes and lead-acid charging has to be temperature compensated, the hotter the lower the charging voltage.
So ausie cars are ok to have 13.5 but cars here in europe where it snows would be a bad practise to use 13.5v alternator?
+Radek Wysocki The voltage regulator has a thermistor in it that takes care of it for you.
The curve is roughly -30mV per °C for a 12V (6 cell) lead acid battery. IOW drop the temp 33° and you need to raise the charging voltage by 1 volt.
24:25 the sound of a chicken getting its head cut off
A little disappointed Dave doesn't watch Ian's channel...
Ian has done two video's on the production of his voltage ref. Surprised to see Ian has not commented.
+T Komoski I did but via EEVBlog forums.
Really enjoyable mailbag video :-)
Get a cheap ovh vps (ping is going to be high tho) for like £3.99 month and and use that as a serving cache.
Dave what display is Ian using on the DC voltage ref...
That OBD two is out of date for late models 14 and 2015 they switch to CAN Just another way for dealerships to keep you on your toes .And as far as you not knowing About cars the dealership I had to go to they don't even know how to use a multi meter or know what it was.

Does it have to be only in Australia? I am 15 and really into electronics. I live in the US. D:
What's up with the audio in this one..?
+Tjita1 Ah, there's the answer.. Nvm..
What happened to the 60fps? Or 50 i guees
What's the purpose of the heater at 28:00?
+Keith Richards The heater keeps the voltage reference at a more constant temperature.
The reference is calibrated at that same temperature, so when the device warms up during use, the accuracy is more repeatable. ;)
It's quite common to find a TCXO - Temperature Controlled Xtal (crystal) Oscillator in equipment that requires high repeatable accuracy. The frequency of most standard crystal oscillators are fairly temperature dependant once you get down to multiple digits.
Where has the 60fps gone? :(
What do you think of rubycon caps? I see them quite often in the more expensive stuff I buy...
+drkastenbrot
Rubycon, Nichicon, Nippon Chemi-con, Panasonic, all good stuff.
That 8060 looks like it could have been a prop in Star Trek TNG as an alien hand scanner of somesort... :P
