Help - Simple solution?

Hi guys,

I'm looking for a simple tasker script that would simply do this;

When screen is off, go back to home screen (i.e. press home button)

So therefore when I open my phone again, it should always be at the home screen rather than my last opened app.

Any suggestions...

Help setting up toppo

Your hacking tutorial - 2 hours 29 min ago,245/
I am trying to set this up to hack it so I can learn (since ctf365's vpn is broken), but I feel as if I must have made an error. While it booted up just fine and gave the correct toppo logo and an IP address, my nmap scan did not work the way this tutorial ( said it would (it said that all 1000 ports were closed and that there were too many fingerprints to give specific OS details) and nor did the dirb command (which said that there were too many errors connecting to the host). Does anyone know how to set this up properly. I am using VirtualBox, which is fully up to date.

Recycle LCDs into LEDs

Hack a Day - 3 hours 15 min ago

We always find it funny when we see ads for modern LED TVs. These TVs don’t use LEDs to show the picture. They are nothing more than LCD screens with LED backlighting instead of cold cathode fluorescent lamps. [Akshaylals] had a few LCD laptop and phone panels that were defunct and decided to recycle them to get to the LEDs within.

Most panels are lit from one or two edges with a bar of LEDs. You only have to peel off some tape and plastic. If you wonder what all those plastic sheets do, see the [Engineer Guy’s] video, below.

[Akshaylals] was afraid that trying to desolder the surface mount LEDs would damage them so instead he simply cut the strips into smaller pieces. To demonstrate the usefulness of the LEDs, he made some large 7-segment LED displays, using two of the “free” LEDs on each side of each segment.

Some super glue and hot glue along with some small wires put everything together. You’d just want to be careful about the polarity of the LEDs which you can check with an ohmmeter.  Probably a good idea to make sure they are working before you glue them down, too.

For a test, there’s an LED driver board that lets an Arduino drive the whole affair with 8 pins. The plan is to eventually use the bright white display in an alarm clock project.

You don’t see many non-LED backlit LCDs anymore, but it is possible to convert. Keep in mind that OLED panels are totally different, so tearing those up isn’t likely to produce an LED strip.

How to run two task in parallel?

Let's assume I have one task T1 which contain 3 Actions A1,A2,A3 . First, I use these Actions Serially A1->A2->A3 , but here even though A2 and A3 are independent of each other A3 only starts after completion of A2 . My question is that is there any way to run A2 and A3 in parallel. Present possible solution I came up with is make Tasker Kid of one action (Let's say T2 Task continuing A3)and start it .

Hashcat and 7z2hashcat Help?

Your hacking tutorial - Sat, 07/21/2018 - 23:12

I'm testing hashcat and 7z2hashcat.

I create a test text file, encrypt it with 7z (AES-256 default) with basic password: 123abc Then I'm running 7z2hashcat on the .7z file and outputting the hash in a new txt file Finally, I'm running hashcat against the txt file with the hash in it, which seems to run fine - but it never recovers the Pw - What am I doing wrong? See below for cmds:

7z2hashcat64-1.2.exe testme.7z > testhash.txt

hashcat64 -a 3 -m 11600 testhash.txt ?d?d?d?d?d?d

Old Phone, New Remote Switch

Hack a Day - Sat, 07/21/2018 - 22:00

With mobile phones now ubiquitous for the masses in much of the world for over two decades, something a lot of readers will be familiar with is a drawer full of their past devices. Alongside the older smartphone you’ll have a couple of feature phones, and probably at the bottom a Nokia candybar or a Motorola flip phone. There have been various attempts over the years to make use of the computing power the more recent ones contain through using their smartphone operating systems, but the older devices remain relatively useless.

[Vishwasnavada] has a neat plan though, using an ancient phone as a remote trigger device, by interfacing it with an Arduino. There are many ways this could be achieved depending on the model of the phone in question, but one thing common to nearly all devices is a vibration motor. Removing the motor and taking its power line to a GPIO allows the Arduino to sense when the phone is ringing. The idea then is that a call can be placed to the phone which is not picked up, but because it triggers the vibration motor it can be used to make the microcontroller do something remotely. A hack with limited capabilities then, but one that is cheap and simple, uses a recycled device, and should work almost anywhere populated on the planet given the global reach of 2G networks.

This isn’t the first respin of a classic Nokia we’ve brought you, they will also talk data.

Wire Wound Resistors On Your Own

Hack a Day - Sat, 07/21/2018 - 19:00

In all kinds of engineering, we build on abstractions in a kind of inverted pyramid. Lots of people can, for example, design a system using ready-made building blocks on printed circuit boards. Fewer people can do the same design using ICs. Fewer still can design with components. But who designs the components? Even fewer people. Then there are the people designing the constituent elements of those components. [Learnelectronics] wanted to break one of those abstraction layers so he shows how to make your own wire-wound resistors.

Wire-wound resistors are often used when you need resistance with a higher power dissipation than a common film or composition resistor. Using nichrome wire makes this more practical since a meter of it has nearly 20 ohms of resistance. A regular wire has much less resistance.  The video shows a drill winding a coil of wire neatly, but this also highlights one of the problems with wire wound resistors.

Actually, the winding introduces two problems: First, the coils could touch each other which would change the resistance. We would have been tempted to wind with a definite spacing on a form and then epoxy it to the form to give it mechanical stability. He builds his resistor into a plastic tube and does mention he’d pot it if he were really going to use it, but that would still make it hard to get the resistance exact.

The other big problem with a resistor like this is that it not only looks like a coil but it acts like one, too. In some applications that doesn’t matter. But in many, you don’t want the giant voltage spikes that comes with a quick change in current flow. We’ve seen this cause mysterious power transistor failures when a wire wound resistor served as an emitter resistor. In addition to inductance, the adjacent windings give the resistor a good bit of capacitance, as well.

Does that mean you can’t use wire wound resistors? No, you just have to get the right kind. Turns out you need noninductive wire wound resistors that use something called Ayrton-Perry windings. The idea is simple. Suppose you need one meter of wire to get to 20 ohms, but you want to minimize the unwanted inductance and capacitance.

You double the amount of wire and make a 40-ohm resistor with good gap between the coils. Then you essentially wind another 40-ohm resistor in the opposite direction inside that gap (or, sometimes, on top after insulating the first winding). With the same number of turns, the magnetic fields cancel out, meaning there isn’t much inductance. And the adjacent turns of wire have about the same voltage on them, so that minimizes capacitance.

Of course, now you have two 40 ohm resistors, but when you put them in parallel you get the 20 ohms you desire. You also used four times the amount of wire, but there’s no free lunch.

You might think wire wound resistors are old fashioned, but they just went high tech. If you’ve ever used a metal film resistor, these are very similar, but instead of wire, they use a very thin film of nichrome that can be as small as 50 nanometers thick. Usually, they don’t wind these, though. They deposit a uniform film and then use some process — these days, usually a laser — to cut a spiral or other pattern into the film, effectively making it a coil. Yes, they do exhibit some inductance as well, depending on the material and the cut.

We’ve talked about making your own capacitors and even your own inductors. We hope when we post about projects where people bought ready-made components, we don’t get a rash of “not a hack” comments. After all, we stand on the shoulders of giants.

Android P vs tasker

Tasker: Total Automation for Android - Sat, 07/21/2018 - 17:53

Android p has introduced restrictions to background access for things like the camera and microphone and whatnot, which is generally a good thing. Unfortunately, this also means that tasker can't do things such as shake-for-flashlight, and toggle auto-rotation when certain apps are active.

Has a workaround for this type of thing been found? None of my profiles work anymore on the p beta, and nothing I've been able to find so far turns up a working solution.

What are the modern wifi hacking techniques?

Your hacking tutorial - Sat, 07/21/2018 - 17:27

I remember years ago I used to use Reaver and it would be very effective in hacking routers. It was so fun.

These days I notice that most routers are Reaver resistant.

What are the new techniques that I should be looking at? I'm trying to hack my own router and want to see if I can do it.

[HELP] Can't manage to use javascript to use shell outside of the tasker app

Tasker: Total Automation for Android - Sat, 07/21/2018 - 16:43

I'm trying to mame a fairly complex macro using tasker javascript capability and while testing I noticed that it execute the shell commands only inside the tasker app.

this is my javascript:

var root = 1;
var timeout = 10;
input(100, 100, 3);
function input(x, y, waittime){
shell('input tap '+x+' '+y, root, timeout);
function waitS(waittime){

As you can see is pretty easy, but when I triggger it (using any mean) it's executed only if I'm inside tasker.

Forntesting I'm using the 'Quick Setting Task' to trigger it for testing, what halpens is that inside tasker it perform correctly and it touch 100,100 (that is the back butto) but if i trigger it in any other app (let's say telegram) it's not performed, and it does not output any error message.

Any idea why?

A Caterpillar Drive That Actually Looks Like A Caterpillar

Hack a Day - Sat, 07/21/2018 - 16:00

[Tom Clancy]’s The Hunt For Red October is a riveting tale of a high-level Soviet defector, a cunning young intelligence analyst, a chase across the North Atlantic, and a new submarine powered by a secret stealth ‘caterpillar’ drive. Of course there weren’t a whole lot of technical details in the book, but the basic idea of this propulsion system was a magnetohydrodynamic drive. Put salt water in a tube, wrap a coil of wire around the tube, run some current through the wire, and the water spits out the back. Yes, this is a real propulsion system, and there was a prototype ferry in Japan that used the technology, but really the whole idea of a caterpillar drive is just a weird footnote in the history of propulsion.

This project for the Hackaday Prize is probably the closest we’re going to see to a caterpillar drive, and it can do it on a small remote-controlled boat. Instead of forcing water out of the back of a tube with the help of magic pixies, it’s doing it with a piston. It’s a drive for a solar boat race, and if you look at the cutaway view, it does, indeed, look like a caterpillar.

Instead of pushing water through a tube by pushing water through a magnetic field, this drive system is something like a linear motor, moving a piston back and forth. The piston contains a valve, and when the piston moves one way, it sucks water in. When the piston moves in the opposite direction, it pushes water out.

The goal of this project is to compete against other solar powered remote-controlled boats. Of course, most of the other boats are using a DC motor and a propeller. This is a weird one, though, and we’re very interested in seeing how the production version will work.
