Figured I would give my two cents on this processor. I have an Arduino Mega and wanted to move out of using it for projects. This seemed like a good start for using something that you can program in actual C and it is much smaller than the Arduino Mega. I hit some small snags with trying to interface to it. I used my Arduino Mega as an ISP, which probably makes things a bit more complicated than just using an actual AVR programmer. Will see how the processor holds up after it has been used for a while. So far processor has performed as expected.

I know this cable is very old and my question is very specific, but it cannot hurt to ask. I am borrowing a friends LPC link that uses a JTAG connection. The LPC Link has a 10 pin connector on it (male). This is then supposed to go another 10 pin connector (male) that splits into the 20 pin for the JTAG. My question is...Does anyone know if this is the right size to bridge these connectors? I do not know the pitch for the LPC link or the JTAG connector or I would not even be asking this question. Thank you and hope you can help.

There are some extreme scopes that can cost the same as a very good home here in Michigan. Ones with 40GSa/s and have full running Window's OS can cost in the high 200s, mostly used in labs though. For hobbyist this scope should be perfect. Not sure what project you would be doing that would need a bandwidth higher than 100MHz.

These things are very good for surface mount parts. They are also helpful on removing hard to grab parts. Not sure if the price is good. I just threw them into an order and didn't do much research. Worked out pretty good though.

Can't say much about these except that they make stripping wires very easy. A friend purchased a pair of these after using mine. The price is pretty good too for the quality.
I am not sure why people are complaining about stripping 30AWG. I thought they worked just fine. You should always be careful when stripping wires that thin, no matter what you are using.

I only have one complaint about this set. It seems no matter how much I tighten the bit into the holder it does not work too well on very tight screws. The holder loosens and the bit rotates inside the holder. I think I might have been using it beyond what it was meant for. Does work very well on taking electronic enclosures apart though. Took apart a Game Boy Advance and an Xbox 360 control with ease. Depending on the use, this set is a very good deal and pretty durable. I accidentally dropped the set on concrete after my first use and nothing broke, I was extremely surprised. Also a friend of mine got one similar to this from Target and it cost him $20. For price and durability it is a nice set to have lying around.

I was waiting for this post. The big problem with the demo version of Keil is that the 32K is for overall flash of the micro, not the amount you are flashing. We used the Keil IDE and the Keil debugger with the LPC1787 for our senior project. Since we were using 512K (same as this micro), we were unable to use the demo version. I will just say that the software and the debugger are not cheap. Unless someone has done extensive research and found an offline IDE that is free, I would not complain about using an online IDE that is. That is unless you have to do things offline such as we did.
I see someone commented about the LPCXpresso, which is nice with the CodeRed/LPC IDE, but the limit of 128K makes it impossible for this micro on the demo version of the IDE.
A good suggestion is to either use the online IDE or just find a micro with less flash and use the LPCXpresso link with the CodeRed IDE. This micro is nice, but a bit overkill for most small projects. There are others in the 17xx family and ones in the 13xx family that can be used with demo IDEs. Good luck and hopefully I helped.

These things are amazing when you need to jump male header pins to a protoboard or breadboard. Used them for our senior design project to prototype and it allowed for things to be organized by using the different colors for different peripherals. Pretty handy when you are using a 208 pin micro controller and the pins for the ports are spread out everywhere. Downside is they are a bit expensive, but all of these type of wires I have purchased from sparkfun are really nice.

Have to agree with Thnikkaman. You usually combat contact bouncing with a low pass filter or with waiting for a string of same states in your code. No matter which way you look at it you are looking at a slight delay if you want to debounce. We are using a mixture between these and the ones with the caps for our senior project and they are pretty reliable.

I purchased these a couple months ago and they are nice wires, but I would suggest going with the 12" wires instead. The wires are kind of short and if you are using more than one board you have use the board to extend them. Overall still not a bad buy.
No public wish lists :(
