Some information about Visteon and the radio: Visteon was originally part of Ford's in-house radio section, but was broken off many years ago so that other companies could buy "Ford" radios without having to directly work with Ford. As a result, many companies, e.g. Ford, JLR (Jaguar Land Rover), Aston Martin - have pretty much identical "main boards" with different "front boards". The front boards are really nice and detachable so that someone like Ford can get Sony to build a front board for the system, plug in their own speakers and can charge more as an upgrade for the customer. Ford then bleeds off the profits cream of the company through various methods, but also has the option to include radios from other businesses without risk to itself. Visteon and Ford have a symbiotic relationship. Business to Visteon is not guaranteed, other companies are given the opportunity to bid for business - which in turn keeps Visteon lean and focused. Those radios really are engineered to last. If memory serves, the CD mechanisms fail despite many efforts to make them robust. Electronics that spin at a high RPM automotive environment is not generally good. I believe the engineers were happy to see the back of them in place of solid state devices (USB, Bluetooth, etc). The radios connect to the CAN bus because they need to know when the vehicle is locked (turn of the radio and go to sleep), cranking (reduce volume so the crank isn't heard on the speakers) and many other very tedious scenarios (there are many). As cockpit electronics have become much more elaborate, it also needs to speak to the "speedometer" area, steering wheel controls, etc. Security is something that's becoming increasingly concerning, especially as the radios have supported USB and Bluetooth for quite some time. "Fortunately" they mostly run a completely ad-hoc OS, so hacking is non-trivial, but not impossible. Most of the modern radios are flashed via a JTAG connector for ARM chips, with serial debug consoles. The old "reverse engineering the codes" trick I don't think works anymore as there is some form of basic crypto, so unless there is a database leak, you're not going to easily figure out the code to get your radio working without the manufacturer. Like all parts of a vehicle, that means your repairs are increasingly at the whim of the manufacturer, most of which consider the car obsolete after 10 years. As for Visteon in Portugal, if memory serves those guys are shut down. If I'm thinking of the right guys (feel free to correct me), they got shutdown literally overnight and the workers told not to come in the next day. The whole situation was pretty shit, but nobody ever notices when some non-end-user facing company does crappy things, nor would it likely ever change their purchasing decisions. In the last few years they have made a move towards focusing completely on in-cockpit electronics and sold off their air control business (which was quite profitable) - then purchased their competitor in the cockpit space. Visteon has historically been an electronics company that does software to make the electronics work - an attitude which will need to change in the future, especially as they work with touch screens, etc. They are used to building software that is complete on delivery, never needing maintenance. As we're seen with cars like Tesla, this whole model is now obsolete and people will be expecting their car updates over the 10 year life cycle of their vehicles. As for the board, I can't remember any specific failures with these, but the insides are pristine. I would recommend swapping out the CD drive and front board for known working ones, allowing you to check if one of those is dead. Other than that, if there's no visible electronics damage, there's probably a good chance the program memory is dead. I can't remember there ever being any checking for memory corruption, or at least any way of handling it if it does corrupt. Another thing to check would be the power consumption of this radio vs a bad radio. If people have specific questions, let me know and I'll try to reply the best I can. I can't give away trade secrets, etc, all of the info already given a good engineer/internetian could work out quite quickly. P.S. I really wish automotive companies would look at devices like these and figure out why they failed and why they lasted so long. Probably the biggest concern is that all of the "lessons learned" are almost entirely encapsulated in each individual employee, rather than into any formal testing/design recommendations.
Interesting information. I have a few Visteon radios from newer Renault/Smart cars - got them from someone that works at the Renault assembly plant (they were scrapped for some reason). I always wanted to make them work without a car, but never could get any information on them. One just says to "Contact dealer" the other shows a FW version and some other diagnostic data. But that is as far as I got.
@@rolaroli It'll probably be more hassle than it's worth, but... You'll probably need to check they actually work (can likely plug into any modern Renault, you're only looking to test the units on the loom). Then you'll want to sniff the packets on the CAN bus and replay them to keep it alive, otherwise it'll go back to sleep. I imagine you could get quite far with an Arduino with a CAN RX/TX shield. Most of the CAN commands don't change over the years (probably online) but you'll probably still need to label them through cause and effect trial and error. That all said, those units could be quite interesting. Sounds like they might have a special firmware version that could be useful to people wanting to reverse engineer them.
@@TheFrenchMansControl It is probably more trouble than it's worth, but they are quite nice radios with Bluetooth and everything. Would be nice for a workshop or something similar. That would require me getting my hands on a modern Renault. I don't even know anyone that has one. And even if I did... these are from a current model of Renault Twingo. People wouldn't really want me to touch their car while it's still in warranty. But yeah, I was thinking about an arduino and just sending out some random CAN messages. But that probably wouldn't be enough. Would probably need to get a log of actual CAN traffic from the car.
Without knowing that, Dave did actually click it in place at the start of the teardown. Later on, he wondered why they used such fancy connectors. LOL.
Nope the 6000 didn't use CAN. That radio came from a Fiesta Zetec which used a thin blue/white wire on a yellow plug to connect to one of the small pins on the center plug for speed pulses. The other pins MAY have been used for phone interface if fitted.Grounding one of these pins should make the display say "phone" and mute it. The illumination dimming was carried out by a feed wire to one of the pins on the large connector that the poster has marked with Pwr/Gnd/Accy etc.. Use both grounds A2 & A6. From the top A1=Batt, A2=Gnd, A3=Accy, A4=Illumination, A5=Alarm Gnd, A6=Power Gnd, A7=Not Used, Small connector C if populated... C3 = Clock disable C4 = Phone (gnd to mute) C6 = AVC 7000 pulses per mile??
Dave, the extra sprung contacts on the car CD player are for the removable buttons on the front ( 2 3 4 5 ). There’s a small release button just above the numbers 1 & 2. Ford’s security feature on quite a few of their players. (even on the cassette version I had, had one, back in ‘04!) 😆
Really just a half-bridge with double the diode drop and an extra useless diode. Lose-lose! A single diode would be better than three. (not that this actually only has three diodes, the fourth is probably just buried somewhere)
The hard drive case is a 20 or more years old design. They just made a new PCB for SATA but the markings on the frame clearly show SCSI information. I have seen them in some self made servers. 1990ish :-)
Yes it will connect to the vehicle can system. Likely to check the module numbers and vin number to see if it’s been removed from a vehicle and put in another one.
30:30 those pops and crackles are buffer underruns, means your acquisition software can't handle the sound buffer fast enough. It's usually fixed by increasing the buffer size (there must be an ASIO buffer size setting in the driver of the sound chip of the camera).
I guess the flickering comes from the mains AC being 50Hz and the camera filming at 60fps. The flickering disappears when the camera is filming at a resolution where it only does 50fps. Amaright?
A lot of car radios also use the CANBUS to connect to steering wheel-mounted controls, to dip the radio volume when parking sensors are in operation (so you can hear the beeps better), to feed a central display for the driver, and of course to switch over to a reversing camera if one is fitted.
Interesting how many car radio related factories there are in Portugal. They've got Delphi Grundig in Braga, too (opened by Grundig in the 1970s for making transistor radios).
The springy pins in the car stereo front are for the pop out buttons. These act like a sort of encryption for the device and will make it useless for anyone without the "key". The little switch in the front will unlock the panel to take with you
I imagine that Dave didn't give that camera the best demonstration but I'm not convinced it's worth what they're asking for at least not in your typical DIY projects, when you can just rip the guts out of 1080p webcams/security cameras for under $40 or re-purpose old phones.
5:35 They have smaller teardrop ones (352AXX and 352CXX models) as opposed to the one Dave has, although they're 2X more. Nice accelerometers, have a bunch of them at work for testing. We also use low triboelectric effect cable in some of our tools since its quiet. I've tested low triboelectric vs. standard coax on a shock machine and its a huge difference. Basically they put a punch of carbon or some form of conductive layer to dissipate the charges formed when the layers of the cable rub or impact each other.
The front buttons are removable on the Ford radio, if you slide the little button across a row of them pop out, this is another anti-theft measure that was used. This is why you saw those nice sprung connections on the front. The radio does not function if these buttons are missing.
I own one of this stereos. They didn't bother to put a fuse in the supply of the CD Changer port (green port). Instead they made the trace so thin, it would light up in case of any fault.
@@bill392 this is why it's important to ask these critical questions. Not sure how they would center tap and rectify the mains for an SMPS without an equivalent linear transformer in the circuit though.
Feeling the VIBE... ❤ to see/hear/learn more about the ins & outs of SHAKE - RATTLE & ROLL if possible. "If I've seen farther than others it is only because I've stood on the shoulders of giants". Leg up please 🤓
I had that radio in my car. The 2-5 key island on the front is a security removable panel and connects to the pressure fingers up the front. The rest of the front panel goes via the ribbon. Be interesting if there is much security in the removable part
There is a standard for after market head units simply refereed to as "iso". Some cars even have it from factory, and you get conversion harnesses for most cars/makes.
PCB Piezotronics! Right here in Western New York. :-) There seems to be niche here for companies making various measurement/instrumentation transducers.
That little camera looks like it just has a lower retention? Which is actually quite nice in some aspects, even if it seems bad? I mean it would have less motion blur which would allow for better recognition of fast-moving objects?
This old car stereo probably had access to the CAN bus only for one function: To adjust the volume with increasing speed of the car. One of the new functions back in the 90s (yes, that's a 90s stereo, not an 80s one).
On that Ford CD player, the 1-4 buttons could be separated to deactivate the radio to prevent theft, evidently there were some smarts in the 1-4 buttons to prevent operation without that inserted. Ford's solution to theft prevention without needing the entire radio facepanel removed.
I've used e-Con cameras for low-quantity computer vision applications and I actually like them quite a bit. The model Dave was sent was a low-light version, meaning high sensitivity and large physical pixel size. Despite his "poor lighting", the flickering is actually because the camera is having to use a very fast exposure time (shutter speed) in order to not overload the sensor. This is compounded by having a fast fisheye lens that brings in lots of light. It is designed for computer vision so they don't do a lot of onboard processing, leaving an unadulterated image for software to work with. Their support for OpenCV (I was using Linux) and tech support were very good! Disclaimer: I don't work for e-Con, I just appreciate decent hardware
Visteon was Ford's electronics division that was spun off into an independent company. I was offered a job there as an university grad but wasn't excited about having to live in Michigan :)
I'm old enough to remember when the first "quick detach" car stereos came out, 80s? You would see people carry the things while walking around the mall. Lster on, you had the detachable faceplates, which could be locked in the glove box.... then people stopped caring about car stereos, since the factory ones started getting pretty good
The 2-3-4-5 buttons can be pulled out of that Ford radio with the tab that's next to them left/up and it works as an anti theft: the radio won't turn on without them in place. This radio has a low speed can bus (lin bus) connection and adjusts the volume as a function of the car speed, it's called AVC in Ford's jargon.
Had one of those players on Ford Transit. The contact pins are for the klip of button row for stealing security. Like the whole front plates used to come of.
Could that camera module be adapted for use on a microscope? Even as a stand-alone, it looks like it could be used for fiddly soldering situations. John's a star for sending in that time circuit box, btw - must've cost a bob or two to make. Done a quality job on it too.
If the stereo has access to the CANbus, it may be because some Fords have a feature that adjusts stereo volume based on the vehicle's current speed, to compensate for road noise. I think the automotive audio amplifier market is currently mostly owned by STMicroelectronics, Infineon, and Texas Instruments. Well, actually, my digikey search isn't bringing up Infineon for automotive audio amps...
Very common to have access to CAN bus on newer car stereos for showing fuel left / doors open / reverse gear detect for rev camera on/ Speedo display / Steering wheel controls / AC control etc..
A lot of US car manufacturers give CAN bus access to the radio to allow it to contain the car alarm circuitry that controls and detects the windows and doors systems and as a means to prevent owners from upgrading their radios with higher quality after market system. It is also there so that on higher end models the integrated display and radio unit can receive, display, and send over radio (like blu tooth) information about the engine. And no, they don't typically secure the radio system they use, but it is short range (

Usually you can set the grid frequency in cameras. Maybe it helps.
Yeah. Would love to learn something about the accelerometer :)
What about flicking the flapping metal, like a Step Function, and see its frequency response?
OMG! 5 seconds in and I've been likened to a tree that falls in the woods! lol
On that Ford CD player, the 1-4 buttons could be separated to deactivate the radio to prevent theft, evidently there were some smarts in the 1-4 buttons to prevent operation without that inserted. Ford's solution to theft prevention without needing the entire radio facepanel removed.
I've used e-Con cameras for low-quantity computer vision applications and I actually like them quite a bit. The model Dave was sent was a low-light version, meaning high sensitivity and large physical pixel size. Despite his "poor lighting", the flickering is actually because the camera is having to use a very fast exposure time (shutter speed) in order to not overload the sensor. This is compounded by having a fast fisheye lens that brings in lots of light. It is designed for computer vision so they don't do a lot of onboard processing, leaving an unadulterated image for software to work with. Their support for OpenCV (I was using Linux) and tech support were very good!
Disclaimer: I don't work for e-Con, I just appreciate decent hardware
Visteon was Ford's electronics division that was spun off into an independent company. I was offered a job there as an university grad but wasn't excited about having to live in Michigan :)
AKADriver nothing wrong with Michigan, was there the last 2 weeks for ford and Chrysler, Had a good time.
I've been looking for that exact Ford CD radio! What will you do with it?
I'm old enough to remember when the first "quick detach" car stereos came out, 80s? You would see people carry the things while walking around the mall. Lster on, you had the detachable faceplates, which could be locked in the glove box.... then people stopped caring about car stereos, since the factory ones started getting pretty good
On the Ford radio. TA = Traffic Announcements. PTY = Programme Type. So either News, Pop Music, Classic, that sort of thing.
The 2-3-4-5 buttons can be pulled out of that Ford radio with the tab that's next to them left/up and it works as an anti theft: the radio won't turn on without them in place. This radio has a low speed can bus (lin bus) connection and adjusts the volume as a function of the car speed, it's called AVC in Ford's jargon.
Had one of those players on Ford Transit. The contact pins are for the klip of button row for stealing security. Like the whole front plates used to come of.
Wow, that's a neat lil' camera.
Vibration frequency should be measured contactless (hall sensor?) to not change the mass which changes the frequency
The flickering could be due to the exposure time.
Could that camera module be adapted for use on a microscope? Even as a stand-alone, it looks like it could be used for fiddly soldering situations.
John's a star for sending in that time circuit box, btw - must've cost a bob or two to make. Done a quality job on it too.
If the stereo has access to the CANbus, it may be because some Fords have a feature that adjusts stereo volume based on the vehicle's current speed, to compensate for road noise.
I think the automotive audio amplifier market is currently mostly owned by STMicroelectronics, Infineon, and Texas Instruments.
Well, actually, my digikey search isn't bringing up Infineon for automotive audio amps...
Very common to have access to CAN bus on newer car stereos for showing fuel left / doors open / reverse gear detect for rev camera on/ Speedo display / Steering wheel controls / AC control etc..
A lot of US car manufacturers give CAN bus access to the radio to allow it to contain the car alarm circuitry that controls and detects the windows and doors systems and as a means to prevent owners from upgrading their radios with higher quality after market system. It is also there so that on higher end models the integrated display and radio unit can receive, display, and send over radio (like blu tooth) information about the engine. And no, they don't typically secure the radio system they use, but it is short range (
There was an anti-flicker (mains frequency) setting on the camera settings
It's grayed out and can't be checked.

i was wondering what camera you like better the flir e8 or the e60..?
Would have loved to seen that camera to perform in really low light, like a flashlight from a phone
yay, new mailbag. At 4am in the Netherlands 😂
Would quite like to see a video on that accelerometer
I'd like to see that video with that vibration thing. :D
Wow, you could cook a small egg on that charger. haha
Love yours videos from spain 🇪🇸🇪🇸
I actualy bought an Accelerometer planning to make aLevel. cannot recall the details but it says "MPU6050" on the underside and "GY521"mon the front.
Please stick the accelerometer on the side of your speaker cabinet and run a frequency sweep.
Where do you put all the stuff viewers send for mailbag?
Dave please do a video on the accelerometer
damn that bulrub at 29:52 made me chuckle hard
"If a man speaks his mind in a forest, and no woman hears him, is he still wrong?
A video on the accelerometer please! That's interesting.
Please do a video about the accelerometer!
