  9. Johnny Chung Lee Interview - Nintendo-Scene Says:

    […] Alan Parekh from hackedgadgets has interviewed Johnny Lee. You may remember Johnny Lee from some of his previous Wii Controller modding and hacking projects, such as the head tracker and touch screen technology. Read the full interview at hackedgadgets. Alan Parekh: What can we expect to see in the future? Any cool projects that you have dreamed up but haven’t yet had the time to implement? Johnny Lee: Hehe, I have a LOT of un-implemented ideas. My to-do list is always growing much faster that I have time to accomplish. Sometimes, I just wish I had an army of developers working for me. Hopefully, my future work will be as cool as the one’s I’ve already done. Usually, I only pick ideas that I think are cool to work on which has, so far, meant other people will probably like them too. But, it’s probably best for me not to talk about them too far in advance otherwise I might burst my own bubble. I guess you’ll just have to wait and see. Sorry to be a tease. […]

  38. Slick007 Says:


    I hope you can help because I’ve been everywhere, no luck in finding the product anywhere…. to be-honest, I don’t think it has been invented yet.

    all it is, is:

    Item = ‘male audio in (L)white + (R)red’ convert the other end of the wireinto a ‘USB PORT’

    Reason = for USB Headphones to work on Tv’s

    Problem = could not locate product, or even if invented yet.

    is it possible if you can please point me in the direction, i be most greatful!

    Thank you for your time and hope to hear from you real soon

    S.lea (U.K)

  39. Alan Parekh Says:

    Hi Slick,

    Looks like someone beat you to the punch.

  40. Slick007 Says:

    close, seen loads of those adapters for the headphones.

    but what i’m after is slightly dif.

    heres a pic: http://www1.dealextreme.com/productimages/sku_5143_1.jpg

    keep the ends of the red and white wire / cut off the other end and change it to a usb … now not the usb stick end but the usb port for a usb stick to go in.. heres the pic of the port.. but not that many just one will do :)


    thats what im after :)

  41. Alan Parekh Says:

    OK I see what you mean. You have a normal audio source and would like to listen to it using some USB headphones. It actually seems a bit of a round about way to listen to audio since the USB headphones convert digital to analog which is what is coming out of the TV.

    As far as I know you will need to plug the TV into a computer so that it can do the analog to digital conversion, then plug your USB headphones into the computer to listen to it. You could do this using a microcontroller that has analog in and USB support but that would be lots of work. :)

  42. Slick007 Says:

    lol that would be a mission dragging my pc to the TV, but it will work.

    the reason I ask of this crazy request, is that i brought a PS3 and a USB headphones.
    The problem is, is that the sony playstation 3 does not play music/video/gameplay sounds through the headphones… all it is capable of it to do, is use the headphones to listen to people talk to you and for you talk back.. (poor design software, apparantly I heard ‘Xbox’ got it right)

    my only other choice was to route the headphones into the TV.. but that is another problem all-together, because the TV is not compatable with usb headphones..

    back to the drawing board I go lol :)

    Its great chatting with you and cheeers v much 4 ur time and assist! :)

  43. Alan Parekh Says:

    If you don’t mind doing some soldering (since I don’t think this’s made) you can solder up an adapter that will plug into the RCA audio outputs of the TV and go to a female headphone jack. You would need to use normal headphones but that would work.

  52. Barry Slator Says:

    I am responsible for the functionality of a “talkback” circuit in a master control room in a radio station. The console operator needs to be able to push a button at the console and speak into a microphone, so the announcer in the booth can hear him/her in headphones. The announcer should also be able to do the same thing on their end. Do you have any suggestions?

  53. Telmo Says:

    Hey Alan. Really like your mini CNC, I also want to make one! I would like to know if it can be used to mill metal (Staneless Steel, and others), or is it only for wood? What program do you use to draw up the plans that the CNC will recieve?TurboCAD? Also, I can’t seem to find the electronical schematics, where are they?

    Thanks alot for the grea gadget.

    P.S – I’am also from Manitoba, like yourself.

  54. Alan Parekh Says:

    Hi Telmo,

    Actually the CNC was only featured here, there should be a link in the article with more details (if more details were available).Great to hear from a fellow Manitoban!

    Could u ple tell me how its made

    I know u are a greate mate and i beg u help me



  60. Alan Parekh Says:

    Hi Mikulas,

    Looks to be some sensors, a microcontroller and a display. Have a look here for an example that may help.

  61. Mikulas Says:

    thanks alan but im not that professional.
    what u say if i get my hands on one of those could we post on your website and make modifications to it? I mean continuing the project that guy has left.
    PS: i have the schematics and soft from that nice motorbike tail light from the Top 5 Brake Light Hacks.
    i could send them over

    Hi Mikulas,

    Sure, drop us a line using this form when your project is done and we can see about posting it.

  63. USB tape drive | IPnerd.com Says:

    […] Alan from Hacked Gadgets has a clever way of repurposing a video cassette tape. This is a great project, and he has a nice cave setup, too. His video shows what the project does, and he does a decent job explaining the reasons and theory behind the build. This project turns a old VHS Tape into a USB storage drive. It looks like a normal VHS cassette tape except for the USB cable that sticks out of the shell. All of the project guts are hiding in the areas around the clear windows so that when you have a quick look at the front of the tape all seems normal. When plugged into a computer the VHS Tape Storage Drive will act as a normal USB drive except when the drive is accessed the tape reel will turn and the windows will light up. This will keep at least one of my VHS tapes out of the landfill. […]

    I was just looking at your article about hacks for dead hard drives. Thanks for putting that up! There’s some fun things on there, but I just have one question. Where can you find dead hard drives? Do you have any ideas? Thanks again!

  68. Alan Parekh Says:

    Hi Mitch,

    Ask around, I am sure some of your friends have a 286 or 386 in the closet that is useless these days. You can also see some of the computer repair shops but they will be newer versions which may not be the best for all projects. There also seems to be lots of recycling places turning up to recycle e-waste, I am sure they would be happy to give away some of the drives if you are going to build something with them.

    Hi Alan,

    Can you tell me more about how to post a picture in the forum? I’m having trouble with that!


  77. Alan Parekh Says:

    Hi Rick,

    I saw your post and fixed it. You need to put the URL of just the image on the page, highlight it and click the IMG button (which adds the IMG tags around it).

    The link you were using was to a page that contained the image. To get the actual image location just click on the image and select property.

    Thanks for entering the contest by the way!

    I liked the Wireless Doorbell into a Remote Control Relay Hack! I built one of them following your instructions and I have
    a few questions. How can I get the relay to latch on and stay on with the first press of the button and then turn off with
    a second press of the button? I don’t want the relay coil to be energized in between button presses in order to save the
    batteries. It should just be energized momentarily to latch on and then again to latch off. Do you have a circuit for that
    or can you show me how to use latching relays to accomplish this?
