Tonight I was working on getting an Arduino accessible via TCP/IP using serproxy on Windows 7 64bit. I got it to the point where I can connect to my pc via telnet using the port in the serproxy.cfg file and get output from the Arduino.
I used a copy from tinkerit on google code in the comments by lanj... The modified source code can be downloaded from Alejandro Valenzuela Roca's blog.
Initially I had a the problem described on the comments where I could connect via telnet to the port and get output once but after that I would get 'Failed to open comm port - Connection refused' errors. The fix was to change the _close statement in sio.c in the sio_close routine to CloseHandle.
To compile serproxy I used CodeBlocks and imported the serproxy.dsp project file. After doing this and making the above change I was able to recompile it and successfully connect to the Arduino multiple times.
I tested successfully using both COM5 and COM14.

aBot – Time for a Break
After two months of working on wheel encoders I have decided to take a break from aBot and spend some time working on making upgrades to my Bicycle Trainer Project.
For the background on this project which I worked on the winter before last see this post.

aBot – Break Beam Wheel Encoder
The two analog wheel encoder designs I have been working with don’t have the level of simplicity I was hoping for. As a result I have decided to try an all digital design that makes use of a break beam sensor. The break beam design means developing a move complicated encoder disk but greatly simplifies the electronics.
The core of this design is a Rohm Semiconductor RPI-352 Photointerrupter. In the picture below you can see the physical setup.
The photointerrupter is connected using double sided tape to a piece of perfboard that has been fashioned into an L. The perfboard is connected to the aBot frame. The photointerrupter straddles a plastic disk which has holes punched through it.
The leads from the photointerrupter are then connected to pins 2 and 3 on the boardino.
Over the next couple of weeks I will work on getting the software setup.
