I suggest you check your modem/router.Combine this with people not changing default passwords, equipment being open to the web by default and some simple port scanning and you have access to emails and ISP accounts of an unbelievable number of people.

So I changed my theme setting to 'SMF4Mobile', assuming I could always change back. The theme looks nice but doesn't display images attached to posts correctly, so I tried to change back. Unfortunately, this theme apparently has also eliminated access to my settings (I can view my profile, that's it). There's a button on the bottom saying "Go to the full site" but it does nothing. I wonder why this broken theme is even available for selection.Does anyone know how to get the old theme back?

I don't think hardware to read floppies will be extinct in 30 years; much rarer certainly, but it'll still exist. They're ECMA standardised so anyone with sufficient funds and the machinery can still build the drives.

Simple Latch Circuit - Is my brain working tonight?! - Page 1

timestamp: April 30, 2013, 07:31:10 pm
content: Hi all,It's been a long day and I have been thinking about a simple circuit I require. Please could someone confirm I am thinking correctly or humour me if not!?If the micro in the circuit shown below outputs high then the circuit will latch and the load will remain powered by 3V_Rail_B. Let's say the micro is reset and during reset the I/O pin is in a high impedance state. The circuit should remain latched? Now if the I/O pin is pulled low then the circuit will no longer be latched?

timestamp: April 30, 2013, 10:20:58 pm
content: Assuming your 3V rail is + positive, with respect to ground negative, I would say yes; it should behave as you state ? although a small cap value on the NPN base to ground, or better still base to collector, forming a sample & hold might help to stabilise, when micro goes low.Rethinking on this; there might be an issue if 3V rail A is below 3V rail B !! but having a common ground... otherwise if the 3V rails are independant of each other as two supplies, then the design should function.

timestamp: April 30, 2013, 10:44:07 pm
content: Yes, it will latch. But it may also turn on by itself, since you forgot a base to emitter resistor on Q2 to make sure it stays off when it's supposed too.Also, on power-up, what ensures the circuit doesn't latch due to momentary H output from the micro? There's no provision for a state initialization by RESET.

content: Quote from: David on April 30, 2013, 07:31:10 pmAs long as R2/R1 is greater then about 6 or greater. The exact ratio you need can be reduced with the base emitter resistor mentioned - a good idea - and it does depend on the maximum battery voltage.A ratio of 10 would be an extremely safe choice - say R1 = 100K, R2 = 10k

content: I'd try thesehttp://www.kogan.com/au/buy/usb-rapid-charger/I haven't used this EXACT one, I've used their older 1A model (i presume the 2A version would either be identical or better), and upon tearing down, seems pretty decent quality;The pins go through the plastic of the case and have wires well soldered too them (not poorly), then there is a reasonably thick sheet of stiff adhesive backed plastic placed on top, to prevent anything from touching them.The PCB sits on top of this plastic and has the wires soldered to it directly (no solder lugs), the active goes through a glass fuse and a resistor, rectified, then an inductor on the output of the rectifier, and 2 450v 105c caps (unknown brand) then into the switcher, through the transformer and out the secondary.There is a large cutout between the primary side of the board and the secondary, there is an opto and a Y cap crossing the isolation as per usual.The secondary is half wave rectified, then passed through a c-l-c to the output. I have not scoped the output, but I suspect it to be similar to that of an official HTC charge I have also recently torn down - if not better, as the HTC has less output capacticane and no inductor either, as well as a similar input stage.

content: the Tekway/Hantek thread is such long that probably some people not checking it anymore, so i try here for better visibility.I posted today the completely reverse engineered schematic of current benchtop DSO, hardware revision hw1007.https://www.eevblog.com/forum/testgear/hantek-tekway-dso-hack-get-200mhz-bw-for-free/msg214613/#msg214613However, i need some help with previous hardware revision hw1005. Hantek/Tekway didn't sold much of them, so i don'thave any PCB of this revision. All i have are pictures and my hw0 and hw1007 schematics, so hw1005 must besomewhere "between".In principle i missing only 3 nets, two connected between FPGA and SRAM and one bewteen DAC mux and the unpopulated"what so ever" (trigger delay?) circuit between input stages and FPC connector.So if someone own such Hantek/Tekway benchtop DSO hw1005 and have some time to help me with these 3 nets i wouldreally appreciate that.For the net between DAC mux and the unknown circuit i need in only confirmation (which mux pin - yellow marked is connectedwith the unknown circuit). For the FPGA/SRAM it would be the best to test it with Altera JTAG cable and boundary scan toollike UniversalScan or TopJTAG (free test versions available). If someone have such DSO in hw1005 revision but no AlteraJTAG cable, well then i will prepare and provide simple FPGA design, clocking with specific frequency on some not used pins(which i assume are used in hw1005 for these two nets).

The device has been sold to a number of countries in the Middle and Far East, including Iraq, for as much as $60,000 per unit. The Iraqi government is said to have spent £52m ($85m) on the devices. Investigations by the BBC and other organisations have reported that the device is little more than a "glorified dowsing rod" with no ability to perform its claimed functions. In January 2010, export of the device to Iraq and Afghanistan was banned by the British Government and the managing director of ATSC was arrested on suspicion of fraud, and in June 2010 several other companies were raided by British police. ATSC was dissolved on 5 March 2013. On April 23, 2013, the businessman behind the device, James McCormick, has been found guilty of three counts of fraud in court in London.http://www.bbc.co.uk/news/uk-22266051
