Hi,
For some projects I need constant Picaxe to PC communication over USB.
The Picaxe download cable is very nice but at 12£ it's quite expensive (compared to the low cost of a picaxe) it also, for a good reason, lacks the ability to power the picaxe.
One example is a project where I upgrade a old NES controller to send button events over USB to my PC where a application written in C# converts the serial data back to keystrokes.
the circuit only draws a few miliamps, far less then 100 mA and runs on 5V so it should be perfectly happy with USB power.
If I google a litle bit I find all kinds of USB to Serial/UART devices ranging from 2.5 USD up to infinity
What are your experiences with these USB adapters?
One of the cheapest is this one from, where else, China:

or this one

I have used the arduino one before but at 10€ + shipping it is almost as expensive as the Download cable.
