First I saw your video and thought send it to Dave. He could definitely power something. As I began a little research the first thing what I saw was s thread at the EEVblog forums about your nuclear battery. And bingo it came to Dave! Pretty awesome what you can do with a bunch of tritium vials and two solar cells.
A friend who works in radiology says he's tested those things and as long as the vial is intact, it's completely impossible to detect the radioactivity. Alpha doesn't go through anything really.
John Ridley I remember reading it somewhere that the layer of dead skin on our bodies can block out alpha rays from the environment. And that radon is soooo darn bad for you because our lungs don't have that layer of dead skin...

In 1978 I had a tritium illuminated LCD Timex watch. It had a very heavy back, which I assumed was for shielding the wrist from radiation while wearing the watch. It still had some very faint 'glow' a decade later!
"The half-life of tritium is 12.3 years. The beta particle that is emitted by tritium is considered to be very weak, hav- ing an average kinetic energy of 6 keV. As a result, these particular beta particles can only travel about 6 mm in air before they lose their ability to cause ionizations. In tissue, tritium’s beta particle is so weak that it cannot penetrate the typical thickness of the dead layer of skin that exists on the outside of the human body. For this reason, the beta particle emitted by tritium is generally only considered to be hazardous if a significant quantity of tritium is, or has the potential to be, taken into the body." hps.org/documents/tritium_fact_sheet.pdf Tritium weapon sights are still quite popular. I have a few sets myself.
Fran Blanch, Tritium is was and maybe used in some luminous watches today, Swiss watches were marked "SWISS T < 25" for less than 25 mC or "T SWISS T".for those less than 7.5 mC. The ones to watch out for are the radium dial watches. I have an old radium pocket watch from 1920s it no longer glows but get it near a GM tube and it soon goes off scale. The half life of radium is around 1200 years. I do not use this watch, it is not running and servicing of such watches is unadvised as the radium paint crumbles easily and if ingested, could have serious health consequences. Best shielding for radioactivity is physical distance as it's intensity falls off by the inverse square law. the greater the radioactivity the further the distance. For my watch a meter is easily sufficient.
Maxx B everytime Dave pulls a goof like that I shout at the screen. I also decide theres no way i'll try and use mailbag to market anything I make since Dave will goof it and cost me sales lol
Your mailbag is always entertaining Dave, it's still got a few years of legs in it. :) Merry Christmas and a very happy new year you you and all whom you care for. 🎄
I thought the tritium battery NurdRage built was awesome. I am looking forward to seeing what you power with it. I ordered 10 tritium vials a week or so ago myself. I am going to try powering a small 3D printed motor with it. I know from personal experience how hard it is to power stuff on less than 1 micro amp. I am looking forward to the challenge.
The Sony home studio used an RC-Lanc plug directly into the camera. It has an IR / receiver/transmitter which can 'learn' your VCR's remote. You then plug the video leads directly between the VCR and camera. The studio uses the timing information coming from the camera tape via the RC-Lanc interface. When you press the buttons it remembers the time codes. When you are done editing, it controls the camera via RC-Lanc and your VCR via it IR remote. It then puts your VCR in record and plays a section from the camera tape. Pauses vcr and fast forwards camera to next section etc. I almost purchased on of these for a sony 8mm cam back in the nineties :)
The instructions at 25:59 clearly state that you store the card info to 1 of the 4 buttons and then press the same button to use that stored card. At 24:00 he uses the button nearest the attachment loop. At 24:48 he tries again using the same button. At 25:12 he tries again successful though we don't see which button he uses. At 26:09 he uses the button right of it. At 26:13 he uses the button left of it. I'm left with the feeling that if he had used the button nearest the attachment loop in his garage, it would have worked. Who else caught that?
Oh, come on. If it worked, you would hardly advertise the fact that you had a device capable of opening other people's doors on the Internet! As soon as anything starts going missing, you're going to find yourself in the frame. No, you'd put up a vid on TH-cam that quite clearly shew the device *not* working, just to give yourself a bit of Plausible Deniability. "Oh, yeah, sure, like I broke into the garage using that crappy key cloning thingamyjig that doesn't even work? I've even got video of it not working!"
Big thumbs up from "duitsländ" (germany). I love the combination of your natural expression and on the other hand competent expertise. i've learned very much from you. Thank you for all, and beautiful holidays to you and your nice family ;)
Good on ya NurdRage for sending Dave the RPG. Can't wait to see what sorts of neat chips or boards he'll show in the video where he almost makes something with it.
I suspect the Sony video editor is meant to be used with a Sony SLV-R5UC or SLV-R1000 S-VHS deck, and can also use the LANC port to control the decks as an alternative to the IR ports.
19:00 quite topical, just had new exit signs with emergency led lighting and neither of us could think of what element powered the radioactive signs I had at another shop years ago
The DIP direction looks right to left @ 8:11. You can see the pads on the left of the chips are fat and the ones on the right thin. 'drip caught on the left', so direction must be R->L at a guess.
I keep a bucket for old batteries of all types. Each month, I go to the local recycling centre and put them in a receptacle. I haven't thrown batteries in the regular trash for over ten years.
Colin McCrory Yep - the front IR window probably trains the editor using the remote controls - you also have to set the timing to compensate for the tape transport mechanisms. Old school!
The 8 pin chips MN3204 in the echo circuit is a classic bucket brigade delay used in guitar pedals, mixers, rack effects, etc. They were an interesting solution to a practical problem in the pre-digital age.
The OKI chips are the sound generating ICs most likely. Casio Electronic Musical division used to have NEC make their chips, but they moved across to OKI in the late 80s early 90s for their PCM and some synthesis based models.
For the key fob I suspect you pressed one button to program and was testing with a different button. Hence it did not work. Well at the garage you were pressing the right and left buttons (assuming top is by the hole). When capturing you were pressing the top button.
FYI some foam packing 'peanuts' are made from starch and dissolve away to nothing in water. They have an open foam surface texture as opposed to the much finer texture of the expanded polystyrene ones.
For the keyfob, I think it can store up to 4 cards, you might need to click the right one while you're using it however to make it work. Also I think you might need to consider orientation while scanning another card.
Capacitor argument: It is going to end up with half of its capacity in a few years, let's put a bigger one. Generally, it works for electrolytic capacitors, you have to estimate the final capacity, not the initial one.
Voltage vs Current curve. Look up "solar cell peak power tracking" and you'll see voltage vs current curves all over the place. If you have open circuit, current = 0, therefore no power is being delivered. If you have short circuit, voltage = 0, therefore no power is being delivered. The optimal point is somewhere between those extremes, where power (voltage * current) is maximised.
now, I need to understand what current means. I know it's analogous to flow of water and voltage is also analogous to pressure. (see, I don't understand these Concepts well enough to say I'm sure and I know it's not wise to show your knowledge weaknesses two strangers, on the internet especially) but this is something I'm really interested in. So thanks
This mailbag is particularly relevant to me today. :) I visited a friend in a gated community today and was like, I need something to clone the RFID in the access card so I don't have to drive an extra 3 miles to the "main" entrance with the keypad. Also, we've been toying with the idea of 32gb SFPs at work. Insane how far they've come with speed!
Some people still use the BlackBerry Playbook. Towards the end of its retail life they were bundled with the oem case and keyboard. Good units but software was lacking.
If only - the hardware was great (nice screen and speakers) and well made build quality but the boot loader was never broken from when I was last interested a few years back. They actually ran a version of Android on top of the Playbook OK so you could put third party apps on but it was a very basic version.
Ian Colquhoun I'm sure BB could have still been big if 1. They didn't bow to the foreign government pressure about the servers. 2. Used capacitive screens instead of resistive. 3. Didn't have the huge delays on product launches.
You made the 555 timer shirt? I love that shirt, bought one a while back when you originally offered it, I just didn't realize that you were the one that offered it lol.
Is the tritium battery why you were doing the dc-dc converter video? :) Looking forward to seeing your electrical expertise used to squeeze every last joule from this and into something useful! (Maybe a lesson on MPPT at ultra low power?)
The "barbecue starter" is meant to be a circular thing. The two tabs go into slots on the other side. As for the sharp things, I believe that they are meant to be on the solid surface4 to allow air to circulate into the inside. No, I don't have one, but I have used charcoal starters (they are usually much bigger) before.
I had a blackberry playbook, honestly it was a really good device while it lasted, you can load android apps on it if you can't find an app in blackberry world, big downside is that RIM never upgraded it to BB10 due to ram limitations and mine eventually died as the LCD controller stopped working. Now I rock an unlocked white blackberry Q10 and its freaking amazing. Blackberry is the only device I swear by, android is bloated, apple is a walled garden, my q10 just works. Never crashes or slows down.
About Tritium PSU...I think you can get mor PowAh!!! Ok i mean more energy over next century(es) from same size inorganic lithium (not organic electrolyte based - regular 3V Li - those are for high power (current) but not so high energy applications.) Something like thyonyl-chloride based, primary, metallic lithium battery. Hi-end ones last fifty years (certified), but in reality likely a few centuries till 50% self discharge...
Your two prox cards might be running different frequencies. That's a pretty old card design, and there were several different reader manufactures and freqs floating around about 15 years ago. Access control systems usually get upgraded in bits and pieces.
+EEVblog I know you got an energy harvesting demo board in a previous mailbag. Try hooking up the Tritium powered nuclear battery to that. If anything can make that thing useful, it's the energy harvesting chip in that demo board.
Key fob fail ouch. Reminds me of another Kickstarter fail. The one you stick on your cell phone and it'll supposedly locate it. (it doesn't) dad was not happy. I'd never buy a Kickstarter item unless I've read the reviews :)
I think you might have to hold the button on the clones keyfob before you move it in range. If you put two cards in range of mine simultaneously it will not read either, even when you take one out of range and leave the other.
@20:10 I want to give tritium batteries a chance for constant current trickle charging. Idealism says I'd put a lot of these units in a flat brick shaped, series and/or parallel pattern to make it a bit more useful, probably use it for a game console on batteries or a small electric vehicle.
At 32:32; What do you mean nobody recycles the batteries? Doesn't the law in Australia require you to dispose of all electronic waste (including batteries) accordingly - as in, return them to specific recycling locations (or special dumpsters dedicated to electronics waste), from where the waste disposal company retrieves them, takes them apart separating all dangerous and hazardous materials and recycles them?
There's a mini-usb port on the car module, you should plug it in to a computer to see what happens. It's using a locking USB-Mini port that I've seen before on the Nexiq USBLINK2 which is an OBDII/CAN etc diagnostic interface for cars.
the Playbook was a very wanted tablet at its downfall, because they dropped the price down to $99. when it hit that price, everyone bought it out from Best Buy and online. There exist Android ports for the platform.
I got a Playbook because they were the cheapest tablet on the market at the time. I now have it mounted to my wall and use it to control my home automation system. It's not really good for much else, it's apps are limited and it's slow and pretty crummy as far as tablets go.
That Family Studio controls looks like it controls two connected machines via the remote IR interface, one with the source material and the other to record the edited material from it. FWIW I used solder thieves on my first SMD PCB design back in '86.
"THIS SUCKER IS NUCLEAR?!" "No no no this sucker is electrical! But I need the nuclear reaction to generate the 5 microwatts of electricity I need." You should use the nuclear battery to power a micro LED and put it behind a mini flux capacitor in one of your Delorean models.
2:45 fancy "COMMAND MODE" stuff... wow 5:54 It's supposed to control a Sony VCR using IR 6:37 I can see that you're starting to make good use of the TH-cam cue cards... 22:26 Down blab... eevBLAB... 32:31 I do recycle my batteries. 36:00 The Wobbleboard...
That playbook reminded me of one dead one given by my friend. These have a very charging design. Once battery drops a certain voltage it would not even power the charging control circuit (yes it true) There is no way to revive it without opening the case and charging the battery directly.
I have two playbooks and use them as music players. They have wolfesn 192/32 bit dacs. They sound absolutely awesome and they are still quite usable. They have andriod 4.3 they have run every andorid app i have thrown at them. They export a CFS file system so you can acesss the file sytem via a network share. Ill send you money to ship that one to texas. Oh yea something like a 270LPI IPS panel movies look unreal on them. They were an incredible piece of kit as yawl say.
yes, I still have my Blackberry Playbook and it still works. It was a pretty decent tablet but I couldn't get a navigation app/charts for it to serve as a backup for my sailboat so I now use a 2013 Nexus 7. Still using my Z10 though.
I still use it for some surfing (hello flash player!) and for music and movies. It has pretty nice display (low resolution though) and decent speakers.
Woohoo! you got my nuclear battery! I was kinda worried it might be stopped at customs for being radioactive.
I watched your video of you building that battery! Pretty neat that it ended up here!
NurdRage this is soooo cool!

I love your upbeat personality and constant joy throughout the vids, it brightens ones day
So what happened to the part of the note that flew away at 2:02 ?
StGSteve They were stickers, because everyone loves stickers. Except for Dave I suppose. I guess he'll find them in a cleanup one day.
Maybe it's the coded message mentioned in the note...? We may never know...
thought i saw something fly off. :)
Dave, you lucky Aussie! With the mailbag, you have Christmas every friggin' week!!!
In 1978 I had a tritium illuminated LCD Timex watch. It had a very heavy back, which I assumed was for shielding the wrist from radiation while wearing the watch. It still had some very faint 'glow' a decade later!
Fran Blanche Would like to have seen the ads for that watch - perhaps "space age" was still the catch phrase as "atomic" was probably out of style!
Yeah, probably doesn't take much to stop the radiation, the al-foil might even do it?
"The half-life of tritium is 12.3 years. The beta particle that is emitted by tritium is considered to be very weak, hav- ing an average kinetic energy of 6 keV.

Tritium weapon sights are still quite popular. I have a few sets myself.

Best shielding for radioactivity is physical distance as it's intensity falls off by the inverse square law. the greater the radioactivity the further the distance. For my watch a meter is easily sufficient.
It looks like the video editor directly controlled a pair of VCRs via the IR remote interface. Probably intended for Betamax units....
Must be something like that.
Hi Dave! Thanks for another great year on EEVBLOG! Greetings from Hungary. Bet you don't get a lot from here in the mailbag. Regards, Adam
Dave, I think you needed to press the button on the RFID fob thing to make it work at the reader.
That's what I was thinking too. I think there are four buttons so that you can use this for four different cards.
Maxx B everytime Dave pulls a goof like that I shout at the screen. I also decide theres no way i'll try and use mailbag to market anything I make since Dave will goof it and cost me sales lol
Of course I pushed the button.
+ituxcoza I did not goof anything, I pressed the button like I was supposed to, it didn't work.
In the video it looks like you held it down rather than pressed and released.
Your mailbag is always entertaining Dave, it's still got a few years of legs in it. :)
Merry Christmas and a very happy new year you you and all whom you care for. 🎄

Not many Canadian TH-camrs? I thought it would be from AvE and got excited for a second.
I'm glad I'm not the only one with that thought.
Instructions unclear: was keeping it on the ice.
My first thought was tesla500, though Dave already received a much bigger thing from him recently
Ave would just drink them.
The manual says: "My hovercraft is full of eels"

A nulclear battery eh? I heard Samsung is looking for those for the upcoming Galaxy Note 8 ;)
arcadeuk you can have your very own mobile Chernobyl with a tritium powered Samsung phone
Maybe the galaxy S7 has a Fukushima Battery on it...
"Mobile Chernobyl" is a fantastic band name
XD good one
"What's the worst that could happen???"
Were you pressing the right button on the keyfob or retry cloning the card that didn't work initially?
Oh, come on. If it worked, you would hardly advertise the fact that you had a device capable of opening other people's doors on the Internet! As soon as anything starts going missing, you're going to find yourself in the frame. No, you'd put up a vid on TH-cam that quite clearly shew the device *not* working, just to give yourself a bit of Plausible Deniability.

Good on ya NurdRage for sending Dave the RPG. Can't wait to see what sorts of neat chips or boards he'll show in the video where he almost makes something with it.
With the keyfob, do you have to press the button associated with the correct card for it to work? Maybe it can only have one active at a time?
That's what the instructions seem to say.
Whats the link for rack mount video editor
at 4:17, that gunshot sound is the same one used in "Owner of a Lonely Heart," by Yes.
how's THAT for trivia?
Do you use the same key on RFID key fob? There are 4 programing slots... First you use top bottom buttons then on doors left and right buttons
Merry Christmas to Dave, Mrs Dave, and of course Sagan!
Have a Merry Christmas everybody!
I suspect the Sony video editor is meant to be used with a Sony SLV-R5UC or SLV-R1000 S-VHS deck, and can also use the LANC port to control the decks as an alternative to the IR ports.
something came out of the box with the note maybe a post card ???
Dynorat 12 Yes, noticed that as well, at 2:00
Haha, out of all the packages to open upside down, you chose the perfect one!
the blue meter looks different from the brymen BM235. is there any new eevbolg meter?
Both units of the Sony video editor can be connected with the little cable stored in the bottom of the main unit (the one with all the connectors)
19:00 quite topical, just had new exit signs with emergency led lighting and neither of us could think of what element powered the radioactive signs I had at another shop years ago
Too funny, Santa holding a Rambo knife.
The DIP direction looks right to left @ 8:11. You can see the pads on the left of the chips are fat and the ones on the right thin. 'drip caught on the left', so direction must be R->L at a guess.
Thanks David Jones for this year Keep up the goos work
W00t! I got so excited when I saw the tritium vials in your thumbnail. Because I was among one of many people telling him to send them to you!
the iclass HID cards are encrypted and require expensive hacking tools to decode.
I keep a bucket for old batteries of all types. Each month, I go to the local recycling centre and put them in a receptacle. I haven't thrown batteries in the regular trash for over ten years.
If you look at the top of the transceivers they are labeled for which side is in and out.
can you explain were does the spin saying come from. example. spin silicon and so on.
Anyone know where to get the Tesla/Edison shirt? Couldn't find it on that site anywhere. Cheers.
Were you pressing the right button on the Keysy?
I think that big knife needs to be sharpened.
I'm thinking the video editing system might just use the IR output to control external vcrs..
Colin McCrory Yep - the front IR window probably trains the editor using the remote controls - you also have to set the timing to compensate for the tape transport mechanisms. Old school!

What are zipper strips for?
For the keyfob, I think it can store up to 4 cards, you might need to click the right one while you're using it however to make it work. Also I think you might need to consider orientation while scanning another card.
I do wonder about the thermal characteristics of the nuclear battery, specifically below 40°C.
Capacitor argument: It is going to end up with half of its capacity in a few years, let's put a bigger one.
Generally, it works for electrolytic capacitors, you have to estimate the final capacity, not the initial one.
17:54 what does that mean? "power curve"
Voltage vs Current curve. Look up "solar cell peak power tracking" and you'll see voltage vs current curves all over the place. If you have open circuit, current = 0, therefore no power is being delivered. If you have short circuit, voltage = 0, therefore no power is being delivered.

The Cisco adapters are SFP's (small form-factor pluggable) devices.
This mailbag is particularly relevant to me today. :)

I think you pressed the wrong button on the rfid reader dave. Press the same one you held during the scan.
You made the 555 timer shirt? I love that shirt, bought one a while back when you originally offered it, I just didn't realize that you were the one that offered it lol.
Yes, I hand drew it.
Awesome, love that shirt. :)
Lol I love how the one time Dave decides to be a rebel and open a package bottom side up is the one he shouldn't.
And I wanted to ask you what do you think about Don Smith generator and Gerard Morin generator?
The Playbook has built in HDMI port.The only problem it has is it needs an uncommon 1.8 amp charger for those two batteries
Is the tritium battery why you were doing the dc-dc converter video? :)
Looking forward to seeing your electrical expertise used to squeeze every last joule from this and into something useful!
(Maybe a lesson on MPPT at ultra low power?)
"That was easy" was a Staples promotional button given out with early online orders.
The "barbecue starter" is meant to be a circular thing. The two tabs go into slots on the other side. As for the sharp things, I believe that they are meant to be on the solid surface4 to allow air to circulate into the inside. No, I don't have one, but I have used charcoal starters (they are usually much bigger) before.
I had a blackberry playbook, honestly it was a really good device while it lasted, you can load android apps on it if you can't find an app in blackberry world, big downside is that RIM never upgraded it to BB10 due to ram limitations and mine eventually died as the LCD controller stopped working. Now I rock an unlocked white blackberry Q10 and its freaking amazing. Blackberry is the only device I swear by, android is bloated, apple is a walled garden, my q10 just works. Never crashes or slows down.
feels that Max Headroom broadcast pirating clip could have been done with such a piece of kit but that was 4 years earlier in 1987.
If you want something similar to 33:29 for SMD storage but much less wasted space, try centrifuge vials. You can easily fit 100 0603s in a 0.2ml vial.
About Tritium PSU...I think you can get mor PowAh!!!
Ok i mean more energy over next century(es) from same size inorganic lithium (not organic electrolyte based - regular 3V Li - those are for high power (current) but not so high energy applications.)
Something like thyonyl-chloride based, primary, metallic lithium battery.
Hi-end ones last fifty years (certified), but in reality likely a few centuries till 50% self discharge...
There was also Family Studio titler.
Your two prox cards might be running different frequencies. That's a pretty old card design, and there were several different reader manufactures and freqs floating around about 15 years ago. Access control systems usually get upgraded in bits and pieces.

I know you got an energy harvesting demo board in a previous mailbag. Try hooking up the Tritium powered nuclear battery to that. If anything can make that thing useful, it's the energy harvesting chip in that demo board.
I saw the thumbnail of this video and immediately knew NurdRage was involved :)
Can't wait to see what you do with the nuclear battery!
My guess is that the IR on the video console might be for Super LaserLink video.
Key fob fail ouch. Reminds me of another Kickstarter fail. The one you stick on your cell phone and it'll supposedly locate it. (it doesn't) dad was not happy. I'd never buy a Kickstarter item unless I've read the reviews :)
I think you might have to hold the button on the clones keyfob before you move it in range. If you put two cards in range of mine simultaneously it will not read either, even when you take one out of range and leave the other.
@20:10 I want to give tritium batteries a chance for constant current trickle charging. Idealism says I'd put a lot of these units in a flat brick shaped, series and/or parallel pattern to make it a bit more useful, probably use it for a game console on batteries or a small electric vehicle.
Aw I thought it was gonna be a package from AvE!
Olivier Doriath same here!
At 32:32; What do you mean nobody recycles the batteries? Doesn't the law in Australia require you to dispose of all electronic waste (including batteries) accordingly - as in, return them to specific recycling locations (or special dumpsters dedicated to electronics waste), from where the waste disposal company retrieves them, takes them apart separating all dangerous and hazardous materials and recycles them?
There's a mini-usb port on the car module, you should plug it in to a computer to see what happens. It's using a locking USB-Mini port that I've seen before on the Nexiq USBLINK2 which is an OBDII/CAN etc diagnostic interface for cars.
Well I would be interested what VID and PID it showed for the device.
The video editor uses Sony LaserLink.
I still have/use my blackberry playbook. It is wall mounted in my kitchen to control some of my home automated appliances/lights/curtains.
Magnetti Marelli are FIAT owned, they make a lot of seatbelt pre-tensioners and other stuff too.
the Playbook was a very wanted tablet at its downfall, because they dropped the price down to $99. when it hit that price, everyone bought it out from Best Buy and online. There exist Android ports for the platform.
No, you're definitely not Rolf Harris. He's been a very naughty boy!
I used to watch him on the telly in the 60's.....
Mark William Mandigers He's currently in prison for sexual offences with children. It's probably unwise to claim to be anything like him.
I know, a lot of celebs went down when the escapades of jimmy savile hit the news, and now it continues with the football coaches.
now Rolf is watching you
I got a Playbook because they were the cheapest tablet on the market at the time. I now have it mounted to my wall and use it to control my home automation system. It's not really good for much else, it's apps are limited and it's slow and pretty crummy as far as tablets go.
That Family Studio controls looks like it controls two connected machines via the remote IR interface, one with the source material and the other to record the edited material from it.
FWIW I used solder thieves on my first SMD PCB design back in '86.
You are correct.
+zawzero And I now see someone beat me to it.
I remember seeing a guy sitting on the street with a C64 and a dot matrix printer selling bio rhythm printouts :-) Must have been around 1985
What happened with the RFID FOB? I think it deserves another look. That thing is awesome!!!!
It did not work because the antennas of the card and the reader were not aligned properly....Duh
"THIS SUCKER IS NUCLEAR?!" "No no no this sucker is electrical! But I need the nuclear reaction to generate the 5 microwatts of electricity I need." You should use the nuclear battery to power a micro LED and put it behind a mini flux capacitor in one of your Delorean models.
2:45 fancy "COMMAND MODE" stuff... wow
5:54 It's supposed to control a Sony VCR using IR
6:37 I can see that you're starting to make good use of the TH-cam cue cards...
22:26 Down blab... eevBLAB...
32:31 I do recycle my batteries.
36:00 The Wobbleboard...
Hey the Sony manual has Finnish as one of its languages!
That playbook reminded me of one dead one given by my friend.
These have a very charging design.
Once battery drops a certain voltage it would not even power the charging control circuit (yes it true)
There is no way to revive it without opening the case and charging the battery directly.
Cisco SX GBIC, is a "S" for short range powered laser diode.
Nice teardowns, thanks for sharing.
Your knife is just starting to get dull again, you might catch it before it gets bad.
I have two playbooks and use them as music players. They have wolfesn 192/32 bit dacs. They sound absolutely awesome and they are still quite usable. They have andriod 4.3 they have run every andorid app i have thrown at them. They export a CFS file system so you can acesss the file sytem via a network share. Ill send you money to ship that one to texas. Oh yea something like a 270LPI IPS panel movies look unreal on them. They were an incredible piece of kit as yawl say.
yes, I still have my Blackberry Playbook and it still works. It was a pretty decent tablet but I couldn't get a navigation app/charts for it to serve as a backup for my sailboat so I now use a 2013 Nexus 7. Still using my Z10 though.
I still use it for some surfing (hello flash player!) and for music and movies. It has pretty nice display (low resolution though) and decent speakers.
Wow I love the idea of Keysy, I'm thinking about ordering one
was just about to go to bed here in Denmark, but noooooo! Dave just had to upload that mailbag!
hello really battery have 1,65 V ? not mV?
