Xmos XK-1pin location observation

Heya LMR Folks.

 I wanted to post this out of concern for the people working with the XK-1 and the actual pin layout vs the hardware manual  pin layout so as to avoid confusion and potential damage to the board if you plan to use the power pins(or any of the pins like the rx/tx pins) related to the jtag ports.

The issue is related to the pin 1 location on the board vs the location specified in the HW manual.

How to connect stuff?

I recently had the great idea of building a robot.


So I went and bought this:


and a PIC 18F4550 IC to go on it, as well as some wires and a couple geared motors and a servo. So... How do I connect all the stuff together so that it works?


I have never done anything with electronics before in my life.

TSA Robot

Hey guys, well I saw that Fritsl was getting on me for having this project in the robot parts but since its still an idea he got pissed so I crawled over to blogging!

Ok, so the workers on the project are Jonny, Colton, and Me.  We are entering this robot into a school competition and the objective is 1) Build a robot that can complete the course.  The course is drive up a ramp, grab a 1 pound trophy and drive down the other side.

Hooking up a Schmitt trigger (74HC14)

I need to hook up a 74HC14 to clean the signal from a QRB1134 IR sensor. I think I know how but I need to make sure. Could it really be this simple:

*Connect pin 14 to 5V (from Arduino)

*Connect pin 7 to ground

*Connect pin 1 to the signal output of the QRB1134

*Connect pin 2 to the Arduino analog in

*Place a .1uF cap between the 5V and the ground wire

Here is the datasheet and an example I used:
