I noticed reading the OLS blog post that you mentioned the PCB was nearly the maximum allowable size in Eagle, have you considered other free and maybe open source alternative such as KiCAD?
Now I have no experience with this type of software, but I have heard of KiCAD before and thought it wouldn't hurt to mention it.
A lot of time I do repetitive work and therefore create macros using AutoHotKey to speed it up. Unfortunately some times I have to work on computers where running unauthorized software is not allowed and therefore I can not use AutoHotKey macros which is where I got the idea for a hardware macro device. Most computers no matter how locked down they are still allow people to use their own keyboards in case they have special needs so I was thinking of a stick you plug in an USB port and it identifies itself as a keyboard (no drivers needed). Now the stick is pre-programmed with a set of keys or key combinations and when a button on the stick itself is pressed it sends these keys to the computer as if it was a keyboard with someone typing on it. Any thoughts on this?
Maybe I thought of this a bit late since most of the design is finalized, but I thought I should mention it anyway. My idea came after I read about the combination of a DSO wing and the SUMP PUMP because I never thought of the possibility to extend the SUMP PUMP before then.
Especially the Proxmark3 is an interesting design because is one device that works as both a reader and an emulator unlike the OpenPCD which is a reader and OpenPICC which is an emulator. Also the Proxmark3 uses a FPGA and no modulation chip from a commercial company which makes it much more versatile, but probably the most important feature the Proxmark3 has and also the reason that made me think about it in relation to the DSO wing on the SUMP PUMP is that it can record, display and replay the RFID waveform. Therefore I would really like to see some sort of RFID support on the SUMP PUMP, if not for the current version, then maybe for version 2 with SRAM support.
I was planning on purchasing a Saleae logic analyzer when they come out with the cross-platform solution they are working on, but then came by this project where the goal is to make an open source logic analyzer with java based software (if I have understood it correctly). Since java is cross-platform and I am all for open source I would much rather be supporting this project, but from the brief reading I have done it seems that a lot of ideas are discarded because of price concerns. I know this is not meant to be in direct competition to other solutions, but comparison with solutions such as the mentioned Saleae logic analyzer is unavoidable, therefore I wonder what the opinions are on how the price is affecting the outcome of the project?
