Sparkfun FTDI Basic fix

Like another user on the forum, I had problems with my FTDI cable and I couldn't program my Arduino at all. It used to work flawlessly, but suddenly it stopped working all together. It's recognised by the computer and by the Arduino IDE, but whenever I try to upload a sketch it displays the "not in sync" message. However, it works if I plug the FTDI cable into the computer, then click upload, and at the very moment when the IDE displays the sketch's memory info I plug the cable to the Arduino.

Hope this helps

Make Your Own PICAXE USB Program Cable

Hi everyone!

I was just wondering if anyone else has made their own PICAXE program transfer cable?

I had all the equipment to make one, 2.5mm stereo jack, colour coded wire, a usb plug and soldering equipment; so I thought i'd give it a go!

The connections for the PICAXE cable seemed very simple (having only Serial in, Serial Out and Ground) and knowing that a usb's connections were quite similar (Ground, Data+, Data- and Vcc) so I tried to match them up.
