    big ear, fm transmitter.

    steven or is it gteven ;D ;D, Just use light gauge wire, a coat hanger ;). Bend one end to an L-shape then secure it to the dish wall with sticky tape, then bend it across to the other side and do the same, I would say you would need three legs. I'm sure you get the idea. Once you're happy...

    big ear, fm transmitter.

    I nearly forgot to mention, you can increase the sensitivity by placing a small dish maybe from a torch, or maybe a (flashlight) hard to come by in Australia though ::) ;D, and place it just above the mic facing inwards. You should view the construction of your dish, the same as if you were...

    big ear, fm transmitter.

    Steven, have you considered The positioning of the mic in the dish, it can make an enormous difference 8). To find the focal point, position the dish towards the sun and use a thermometer to find the hottest spot, which of course is the focal point, be careful because you can easily destroy...

    big ear, fm transmitter.

    Hi It's just downright annoying, the pages were loading that fast yesterday, I nearly fell off my chair in disbelief :o. Well it was good while it lasted ::). That's my whinge for today, I feel much better now ;D ;D ;D.

    Playing with hydrogen

    Steven, I decided its time to sort out the mess I have made of my hard drive, and try to create some order from chaos, man it is a mess no wonder I can't find anything :o. Anyway I came across this :) http://www.fortunecity.com/greenfield/bp/16/hydrogen.htm (its worth a look) if you haven't...

    PC Oscilloscope

    Hi CRE, I am also wanting the same thing :D, something not too complicated and most importantly, I can be confident it won't damage my computer. I amended the link I posted so now you can just click on it, but it's still not working :( hopefully it comes good because it's worth checking out...

    PC Oscilloscope

    Check this link out, it looks very good but very expensive To make. http://alternatezone.com/electronics/dsoamk3.htm I asked about PC oscilloscope awhile back, and someone posted this link.

    big ear, fm transmitter.

    Hi, I made an FM stereo transmitter using the BA1404 and it works ok, but the sound quality is poor and my stereo has a hard time picking up the signal and its only about three metres away, if the single isn't strong enough or if there is any slight drift it will drop out, the stereo...

    recorded voice player

    If you are referring to the schematics I posted, sorry I'm not sure, I think it's 20 seconds. It may also be obsolete, but there are many others that you can use for different record Times. I have come across one that will record up to 60 seconds, rather expensive though. I haven't yet put...

    Hobby lathe, metal turning.

    Hi ante, Yes of course, I should have realised the motor choice would need to be known first ::). I'm looking at two possibilities, a washing machine motor or a small benchtop drill press, a drill press would probably prove to be the most cost-effective, around $100 because it already has the...

    Hobby lathe, metal turning.

    Thanks ante, Very very helpful ;). Question ante ;D, what is the best method of varying the AC motor speed 240v 50Hz 1/2 3/4 Hp, in addition to the mechanical gearing. It will need to be very stable especially if I want to eventually use it to cut threads. Thank you.

    Pages take forever to load?

    Is it just my computer :-\, or is anyone else having these problems as well, it happens about 70% of the time. I don't seem to be having these problems elsewhere on the net.

    Spray Etching Machine

    I think it is very important that the etching solution is applied to the PCB evenly, and the pressure is applied evenly to the entire PCB to be etched, to ensure the etching process takes place evenly over the entire board. You don't want to end up with a small area on the PCB that takes twice...

    Spray Etching Machine

    mixos, I just realised something ;D, I think this is a really good, (inventive/new idea) a true (bright idea). I think this would be a very useful/popular project to build, so I think it would be good to keep in mind, the (mechanical construction/hardware) and try to use commonly available...

    Hobby lathe, metal turning.

    Does anyone have any information for a DIY metal turning lathe, Just a small basic one. It will come in handy for my hydrogen project, for the construction of the reactor chamber. Thanks for any help :).

    Spray Etching Machine

    That's a great idea mixos, and I already have 95% of the equipment and materials to put it together. You could use a low pressure spray gun, that works on a venturey system, I have several of these spray guns, two of which can be easily modified to be noncorrosive. Hang on a minute, I have a...
