content: Quote from: cdev on January 05, 2019, 02:47:12 pmHere's the thing most people miss. If you add up the total impact of street crime -- the total value of things stolen by street criminals in the USA it works out to something under $20B USD per year. So, all the muggings and car jackings and burglaries and typical bank holdups -- all of it works out to about $20B per year. Meanwhile, one man plundered $60B. These high end white collar criminals are vastly more impactful to the economy, but the laws and the law treats them differently. But even the $60B ponzi scheme by Madoff pales in comparison to the trillion that was siphoned from the economy by Wall Street and the Banking industry just a decade ago. And even that pales in comparison to the transfer of wealth and income from the working class to the leisure class that's taken place int he last 40 years. Estimates for that begin at about $15T.Brian

content: What gives with con men named Bernie? Before Madoff, the biggest con man was Bernie Ebbers. Maybe the name Bernie inspires trust in some people. Bernie Madoff had two names going for him, first is "Bernie" and the second was how much he made-off with.

Has Xeltek gone belly-up? - Page 1

content: As the title suggests, has something happened to Xeltek? I attempted to buy a programmer from them 2 weeks ago via Amazon, and after several days Amazon emailed me that Xeltek had not responded to the order.Last week I emailed them, and have heard no reply.Today I phoned, and the Operator, Sales and Tech Support options go to voicemail. The on-line tech support chat is off-line. All of this at 3:30 on a Thursday afternoon.The company website does not have an announcement that (for instance) the plant is shut down for two weeks for Xmas and New Years.I find nothing on the web about them closing, but this may reflect on my Google-fu, or lack thereof.Am I the last to get the joke?

content: It looks like Xeltek Inc is just a distributor now in the US and imports the hardware. There is a separate Xeltek in China who designs + manufactures all of the hardware.Doesn't look good for Xeltek Inc with the lack of order fulfilment, voicemail and Digikey listing that once the current stock of Xeltek products runs out, it'll be going special order with minimum order requirements.Xeltek have been trying to rent out one of their offices since September(looks to be the founder of Xeltek?). There is a definitely closing down vibe there.Their Facebook and Twitter pages have had a post mid December so somebody was around recently though.

There are a wide range of material, printing methods, coatings, and adhesives that can be used depending on the application and the aesthetic requirements.In the US, I've gotten those types of labels as well as LCD/membrane overlays fromJN Whiteand would definitely recommend them.I know they ship worldwide, but not sure if they have reps in the UK. When we were figuring out our labels and overlays their local rep brought in a huge binder of samples so we could see and feel the options, which was a huge help in finalizing our designs.

What normally happens is someone signs up, posts a load of meaningless, but not spam posts such as "Good forum", "Thanks for the information" etc. then starts spamming. Fortunately the administration team have recognised this pattern and will ban a user quickly when they spot it.Sometimes they have to ban IP addresses because a spammer will just sign up with a new account. Unfortunately IP addresses are sometimes shared by many people with the same ISP, so if one user spams, they all get banned.

content: When you first turn your laptop on the keyboard interfacing is controlled by the BIOS and it's almost but not quite at hardware level. Once you boot linux the keyboard driver overrides the BIOS and enables things like softkeys for AV control.Finally, I agree with tom66. You have a loose BGA solder ball somewhere on your laptop PCB and pressing the shift key is enough to generate the problem. Take the machine back, that's what warranties are for.

(this battery is internal and screen/device charges it. has a 12v barrel connector)2 questions:1. what does the T stand for "Temp sensor?" when i ohm check/volt meter between it and either of the other 2 pads ( + / -) nothing and no voltage2. how does this battery charge with only 2 wires ( + /- ) im used to lipos which have a balancing lead for each cell.... but it has to be 2 cells since its 7.3v...

I would stick with lowish current charging as well just in case (<1A).

LED retrofit for fluoro illuminated magnifying lens lamp? - Page 1

content: The donut shaped fluorescent tube in my old magnifying desk lamp has died so I was wondering if anyone in a similar situation has tried doing a retrofit using LEDs.The magnifying lens is 120mm in diameter and the lamp housing is 220mm in diameter so I've got about 45mm or so room for the LEDs.The original bulb was 22 watts. Do you think a bunch of multicolour LEDs like the WS2812 would do the job?

content: Order a LED ring light of the right diameter on Ebay and a power supply for it, or just get a few pieces of your favourite colour white LED tape and some aluminium strip to act as support for them, plus a 12V supply. Otherwise the 22W circline is still available, and quite cheap.Alternative is to cut a circular piece of aluminimum sheet that replaces the light, and get a whole load of 3W star led units, and use some epoxy to attach them to the sheet, and cut a diffuser from thin white acrylic to diffuse the light. Then get a LED power supply appropriate for the unit and install it in the top, leaving the original ballast in the base to provide mass.

content: Search for "LED circular tube". You're probably looking for the 8 inch ones, for those that aren't advertised in metric.You can find LED direct replacements, simply plug and play using your existing ballast. Old ballast must work, of course.Or you can get the same thing with a ballast replacement power supply (wiring required). You'll have to find a place to put that, should it turn out to be bigger than what it's replacing. Usually a bit cheaper than the above.There are also flat LED ring PCBs that do pretty much what you're thinking of. Most of the ones I've seen are for ceiling lights that assume they can put the power supply in the middle, so that might be an issue. Buying a cheap round LED ceiling light and removing the guts may be a fast way to get one of these.And, there's DIY. If the project is the real goal here, go for it! Many different ways to do it. Have fun! The numbers you need to compare with the old bulb isn't watts, it's lumens. The LED replacement will consume fewer watts for the same lumen output. Color temperature is another thing you need to decide on. You can pick something specific, or you can mix in several different types of LED's to get a wider spectrum.

(so are earthquakes! Ive actually seen that and its really strange!)The following is really worth reading because of its description of phenomena that give hints that the Krakatoa eruption may have been simply the most visible to human eyes of a number of related volcanic events over a large distance.https://www.theatlantic.com/magazine/archive/1884/09/the-volcanic-eruption-of-krakatoa/376174/A really huge volcanic eruption near the Equator could cause a global food and energy catastrophe by reducing the amount of light that reached the Earth in both the Northern and Southern hemispheres for several years.

The cameras probably already have a set of correction factors available for the lenses back at NASA so they know just how the images will be distorted by the fisheye lens as they go off axis, and the markers are there to verify the correction factors in image processing.

Bluetooth security aspect today after 'Blueborne' vulnerability? - Page 1

content: I was listening to Dave's video on the new bluetooth speakers, and I couldn't help but wonder for myself, yet again, what Bluetooth security is like. I tried figuring it out some time ago, but I was not able to.The reason I ask this here, is that I don't understand the previous vulnerability (or maybe a set of vulnerabilities) called 'Blueborne'. Some known set of 2017 vulnerabilities related to Bluetooth I think. Said to have impacted maybe billions of unites unless I remember that part wrong.https://en.wikipedia.org/wiki/BlueBorne_(security_vulnerability)I asked in the Microsoft thread on Reddit not too long ago, but it looks like my thread was deleted for reasons unknown to me. Rules say things has to be "news" related *shrugs*. I simply asked what the status was for the now known Blueborn vulnerability.So, what I am wondering is:Where exactly is the damn vulnerability?Is it in the standard somehow?Is it in the hardware of headphones and anything else that connects via Bluetooth standard?Is it the firmware of said hardware for headphones and the like?Is it the drivers on say Windows machines, that uses an antenna to connect to Bluetooth units?Is it related to Windows and Linux operating system?Is it related to USB Bluetooth transmitter/receiver? Or its drivers, firmware or hardware?As an owner of Sony's wireless headphones, I am bewildered as to what Bluetooh security is, and I find it disgusting to think about it.Anyone have a clue about Bluetooth security after 'Blueborne'?

I find that after I press the small off button on left side supply, set the current limit knob to 0, the LED on top will turn red. If I set the current limit knob to about 0.008A, the LED will be off. Anyone know is this a defect? Will the problem degrade over time? The right side of the supply doesn't have this issue, I assume this is good.Thanks for the advice in advance.

content: I’ll start by saying I haven’t seen inside these generation of TTI power supplies.From memory the old ones used to use a double pole switch that would turn off the output and also give a signal to the micro that it needs to display set current not actual current.The circuit behind the switch was still running.There might be a bit of leakage that means when the current limit is set to lower than 8mA it can’t maintain the set voltage and will enter current limit mode.For example, I set my dp832 to 1mA 13v and the voltage drops to 0. 3mA is just maintaining ~6v and 4mA is slowly increasing the voltage.Power supplies like this will behave a bit odd when they are at the extreme lower end and as such I wouldn’t be overly concerned about it.I’ve used the older PL330 supplies for 15 years, plus I have a new PLH120 which is an awesome bit of kit.
