I just downloaded the new BackTrack distro from Offensive-Security (BackTrack 3 Beta). It's interesting. It has a lot more graphics than 2, and it looks like the computers that all of the "hackers" use in the movies. I don't know if that's cool, or a bad thing. Has anyone else tried BackTrack, and if so what do you guys think about it?

I got an old industrial sewing machine cheap. Cheap because it has a 3-phase motor, which made some other hobbyists reject it. The other option at ~150$cdn would be to replace the motor with something more domestic.

Iam wondering if I could get two walkie talkies (2 way radios but I prefer calling it walkie talkie) and add two 3.5mm jacks one for ear phones and one for a mic. Using a splitter 3.5mm for the sockets, a 3.5mm mic and a 1m extension for the mic so I can put the walkie talkie in a pocket. Can someone tell me if this will work please and any suggestions for improvements to my plan

I have got a pair of Sony MDR-1R headphones and a pair or Sennheiser MM30i earbuds, both featuring an in-line remote and mic. The question I have is: does anybody know if there are some kind of splitters to split the cable in audio and microphone jacks to plug in my laptop? I'd like to use the mic on the cable, rather than the one built in my computer or, worse, wearing skype headphones just to pick up a call.. Thanks in advance!

I want to power my GameBoy Color using the USB port. It needs 3V ( 2 AA batteries). I found a voltage regulator, that puts out 3V, but it does not seem to be available in Germany. But there are loads of 3.3V regulators. So I wonder, how I could use one of those. Is it possible to simply put a resistor in row (if yes, what value would be suitable?) or is it a bit more complicated?

So yes, my dad has said he will choose the PS3 as the free gift. So as you see im Estatic! I thought I might aswell get some info about the console, from gamers like yourself on instrutables. Just answer the questions: What is the best game to get on a PS3? Any regrets on buying it? ( e.g would of chose a different console, not worth it) Is it backwards compatible with other PS2 games ( if not is there a way to make it?) ? ( Im getting the 40gig - the only model available ) Which console do you think is going to win the next gen war? ( xbox has put up a good battle but the PS3 is picking up speed fast!) List of ps3 Must haves!!!? please. - Baron

Question by nerd7473 | last reply
I noticed a slight glow in the light when it was switched off. LED bulbs in a ceiling fan/light fixture. House built in 1905, wired whenever? using all-fabric insulation type wiring but not knob and tube . Removed the load from sw 2 and tested travel wire voltages and got 95 v on one and 25 v on the other. Flip sw 1 and the voltages trade wires along with the switch position change. The switches tested OK but replaced both anyway and got duplicate readings when repeating tests. Isolated the travel wires and got no continuity (infinite resistance) using all scales of an analog meter as well as a Fluke digital multi-meter.. We checked for voltage feedback from another circuit and even used an extension cord to a different circuit in order to use a different ground wire. With the load connected, the travel wire being used shows 120 v but we still get 25 v on the other wire. I discovered this because when I bought the house only sw 2 worked the light, and one travel wire was disconnected at sw 1 and taped off.. I have not opened the ceiling box at the fixture because the problem exists when the wire to it is disconnected.The previous owner said he didn't remember what sw 1 went to because it hadn't worked for many years. So we eliminated worn insulation or nail into the cable because either one would cause a resistance reading below infinity. All we can think of is a legacy doorbell. Neither of us remembers working one, but I know some used 120 volts and a relay. People have told me that relay contacts can cause this problem when they get worn. Does anyone have any ideas? I'm retired on a fixed income and tearing walls open is an absolute last resort. Thank you in advance for any advice I can get!

Is it possible to replace the IR receivers from the xy axis's, with a rotary encoder from the scroll wheel? Is it just a matter of removing the IR receivers and putting in scroll encoder dials from other mouses? Now on top of that same idea, can you use pots instead of the rotary scrollers? I cannot find a pinout from a scroll wheel or a IR receiver anywhere...one of these would be nice also. The mice I'm speaking of are the early type non lit underneath. However a workup of both types wouldn't hurt as this will help with the newer stuff. End result being able to use 3 separate dial axis and buttons from one HID mouse board.?

Ok,so I get a 3 volt signal from a detector and use this 3 volt to trigger an alarm which atleast need a decent 7 volts to function.The detector could take a max. of 5 volts input which I got from the 7 volts DC supply.This 5 volts fed,gets transformed into 3 volts after the detection.So let me make this clear,I have a 3 volt and a 7 volt supply.I need to use this 3 volt to trigger the 7 volt circuit.I know what you are thinking-a relay !right?but I couldn't get a 3 volt relay anywhere(though I got a 5 volt relay).I can tackle this situation in two ways.1)Either by stepping this 3 volt to 5 volts and making the relay do the job.but how? 2)Or some circuit to use this 3 volt to trigger the 7 volts(like a relay but maybe by using ic's).This is the final part of my project and so please help me.

I am adapting a 1:6 scale motorcycle and sidecar for one of my GI Joe/Action Man figures. I would like to put a 3 wheel radio control unit in the sidecar base so that when attached to the motorcycle it drives the combination. I expect someone has made or adapted a 3 wheeler for this type of use but I can't find one anywhere. Any help will be very much appreciated. I've attached a picture of the motorcycle to show some of the upgrades I have already made (the lights are LEDs with an on/off switch in the side panel and coin cell in the pannier).

Kitewife just bought a Christmas decoration, but when it came out of the bag, the connection was as shown in the image. The loose wire is already a safety concern, about which I shall be contacting the store, but I also I thought that appliances sold in the UK had to have a plug moulded onto the power lead? Since the decoration is lit with old-style filament bulbs instead of LEDs, I am wondering if she has been sold something that has been sitting in a warehouse since before the legislation changed?

OK so I would like to use a solenoid to unlock a box from the inside, problem is the electronic circuit I designed inside the box operates on 3 vdc and as far as I can tell most solenoids operate on a voltage of 6-24 vdc. Is there any way to make a simple driver circuit for a solenoid so it can operate on 3 vdc? Below is a copy of the box's circuit so far. I would like the solenoid to be in parallel with the "puzzle solved LED."

Hey have been thinking on how to modify https://www.instructables.com/id/Altoids-Tin-18-Stereo-Mixer/ to accept a 3.5mm 4 pole conductor as the output while splitting the mic to the inputs. This is going to be something like the Iphone ear buds with built in mic. I just got a pair of amplified 4 pole headphones with mic that I want to use for everything. Here is my wish list: 3 - 4 pole Audio in (iphone, macbook, ...) 1 - 3 pole Audio in from computer 1 - Mic in from computer 1 - RJ10 (so I can use my headset with my cisco phone) The audio mixing is basically the same as Rich's write up. But im not sure if I can just split the mic to everything. If I am sacrificing mic volume by splitting to every input I could limit it to the CPU mic and the RJ10.. the ones i really want. Please let me know any ideas or advice you have. Here is my purposed schematic:

I am working on a voice transmission project by using Spartan 3e. My code works just fine. My problem is that i give analogue input to adc side by using a potentiometer and see the changes (as digital) on leds ( digital output is assigned to leds). Here is the problem, i cut a headphone into two and connected 3.5mm jack side to my phone to play music. There are 3 cable which are golden, blue and red. Golden one is connected to "GND" pin , Red one goes to "Va" pin (at adc input). i didnt touch the blue one. When i play music, i see no change on leds despite the fact that i did see by using potentiometer. What am i missing ? Do i have to setup an external circuit before giving the analog signal to Va input ? Thanks in advance.

Hey guys! I had this little flashlight that worked great for years. I would plug it into the USB port on the computer to charge it. When it broke I took it apart and it had a small battery connect directly to the 5v and GND of the USB cable.

Some stereos now have female usb sockets built into them to play music from a memory stick. Mine does not, which is why I am looking to make/buy a usb to 3.5mm audio out device that can read the files on my memory stick and output them as audio. I have done a concept picture using professional editing software 'Paint', but the sd card reader is not really that necessary. It could also be battery powered, the picture is just a basic idea of what I want. I have spare computers I could raid for parts if I need. Any help would be appreciated either building or buying such a device, but low costs for both are a big need.

Hello: My name is Charles and I am 51 years old,all of this Computer Technology is all NEW to me as I am OLD SCHOOL if you know what I mean.I have had a Nervous Breakdown due to Stress,and have lost a lot of my Technical Memory.I am trying to pick back up on the Electronics for a pass-time,but things don't seem to make sense like they did before.I wanted to know how I can ask questions I have about the Electronics I am wanting to work on.As of right now,I need to see if someone can explain when using OHM's Law (Power is equal to Voltage of your Input times the Current needed in your Circuit).I have a 3 Watt Red L.E.D. which should run at 2.5-3.0 Volts with a 700 Milliamp Current.If using a 3 Volt supply times .700 would equal a 2.18 Watt Power for the Resistor.That does not sound right to use a 4 Ohm - 2 Watt Resistor for a 3 Volt Input.Is this really right or have I gotten confused somewhere?Thank you very much if you can help me out,Sincerely Charles.
