Build Your Own Mac for 9

Build Your Own Mac for $199

X86 While it was always possible (although costly and time consuming) to cobble together a PowerPC Mac from old and new parts, hardly anyone did it. Now that Apple has introduced OS X for Intel processors, however, it’s conceivable that you could soon be building your own Mac from scratch. One user, CEpeep, shopped around and found everything you’d need to build your own Intel Mac for under $200 – no rebates, no refurbs. Obviously, there are still many reasons why you’ll want to buy a true Mac – Apple quality and support (and innovation), the current lack of a legal x86 OS X, etc. But it’s interesting to think that the days of the do-it-yourself Mac may be just around the corner.

Circuit to use old phones as intercoms

Images-11 Here’s a good post from 1993 on making a circuit to use old phones as inter-comms- Talking over the phones is easy. You put DC current through the phone and it transmits and receives audio. So two phones and a current source (about 25mA) all in series will give you a talking circuit. A suitable current source can be as simple as a 9V battery and a series resistor whose value is adjusted (with both phones offhook) till about 25mA flows. Link.

Build a -better- NES PC

Build a -better- NES PC

Nes2 Why is this NES PC better you ask? Well, first off I went with a real Intel MoBo/CPU (As apposed to the VIA EPIA all-in-one boards). I also installed a GeForce 2 MX video card to allow me to play recent 3D PC games! Lastly I wired up the front controller ports to allow me to use my original NES controller with an NES Emulator! And I did this internally! This means no ugly wires plugged into the back of the NES looping back inside the case!…Link.

How To Transfer Windows XP Activation Information…

Images-8 Nice tip. Users who reformat their hard drive and perform a clean installation of the operating system will find that they need to reactivate the product. But, as long as the new installation is on the same system and there won’t be any hardware changes it is possible to transfer the existing product activation and skip having to go through the product activation process again. Follow the steps below to save the activation status information and restore it once your system is rebuilt Link.

The-Quick-Brown-FoxHektor consists of a suitcase which contains two electric motors, a spray-can holder, toothed belts, cables, a strong battery and a circuit board which is connected to a laptop and controls the machine. The motors that are mounted onto the wall suspend the can holder through the toothed belts and define its position by changing the length of these belts. Thanks Doug! Link.
