    Matt, Is there a working prototype of the Bandit? Is it designed to be used from the wheelchair (a la the RTI300) or from a fixed seat (a la the ERGYS and StimMaster)?

He would be interested in alpha or beta testing OpenFES. He would also be interested in building his own copy if you wanted to share enough of the design.

      If you are thinking of selling this as a product, are you looking to open an East Coast sales office? We live outside of Boston.

      Hi Mary-Anne,

      We could always use a good java programmer. The UI is written in Java, and right now I need to get it to talk to the Linux kernel module that controls the stimulator. I have no plans as of yet to sell anything, I just want to get a complete proof of concept. I would be interested in speaking with your partner is he is serious.

        Hi Stephen,

        There is a prototype, but it has not been fully integrated. What we have so far is the ability to turn the crank on a repurposed passive arm/leg trainer, while the linux kernel module reads crank position from a rotary encoder and determines what muscle group to fire, how many pulses, and at what amplitude. The kernel will then send this information out the i2c bus to the digital tens controller where it is decoded.

        That is the basic meat of the project. We have two other pieces that need to get integrated. The Java UI needs to read and write to the kernel, and the analog tens modules need to receive signals from the digital controller.

        We are in the process of fabricating a more compact version of the TENS unit. It's basically a last mile problem at this point. We only have a few things left to do, but this last 10% is feeling like more work than the first 90%.

        Matt

            About alpha testing an Open Source FES unit, he would be very serious.

            I tried to find the code for OpenFES. I found something on google, but it did not show signs of recent activity, so I am guessing that the current version is elsewhere. Would you care to say where?

            I also tried to track down your (Matt's) email address and I did not succeed.

                  I am just about finished with the first version of the UI and the kernel drivers. You can check out the Java at http://openfes.googlecode.com/files/openfes.jar and if you have a beagleboard, you can get the kernel at http://openfes.googlecode.com/files/uImage_openfes_v0.2

                    Anyone

                    Is anyone interested in working on an embedded project this Summer? I was thinking of porting my FES UI from Java Swing to Android. Admittedly, I lost some motivation after I started making enough money to buy my Ergys but if I had someone to bounce ideas off I would pick it back up. I figure, at worst we could put it on our resume's and send them to Google/Apple. PM me if you are interested (and qualified).

                      Hey Matt,

                      Did you actually get to a working prototype stage?

                      Are you looking to put the code on a tablet or phone based device?

                      Cheers

                      BR

                        Rowing

                        Hi,
                        There is an interesting project going on in Boston at Spaulding Rehab in Boston with rowing. I did not fit criteria for the study, but got some good ideas. I am using an Odstock FES system that I got from England. It works great. I know from experience that you need to develop some good quad strength before you start rowing because otherwise you develop a funky rowing pattern, that involves a double pull. There are some interesting videos on-line that go with the Spaulding study.
                        However, I don't have the talent or skills you requested such as PT, engineer etc..

                          Hi Bikeracer,

                          I got everything except the juevos to hook up the AC. I was thinking of switching to Android development, but only because taking another step would mean I actually have to hook this thing up to myself.

                          Hi Moira,

                          I have been following the UK rowing projects, but I have had difficulty joining their circle. It seems like they share a ton of information, I just haven't been able to fit in. I got so far as to figure out what mechanical off-the-shelf rower they are using, how much power their FES units are putting out, but I dunno how many channels, anything about electrode placement, or firing patterns. I'm kinda jealous and I wish I could just pop in and ask somebody.

                          M

                            Housekeeping alert: This is a dead thread. I don't think it merits "sticky" status any longer. Matt, the OP, hasn't visited CC since 2011.

                              Matt had a worthy goal. In his first post he had an .edu email address, which may not be good anymore, but why not try to contact him by it and pm for an update first.
                              I have had periodic paralysis all my life. I lost my ability to walk in 2011 beginning with a spinal block, which was used for a hip fracture caused by periodic paralysis.

                                I kinda think that if he had an update worth sharing he would have done so already, no? Three years is a long time to stay away from CC after having been such an active member.
                                At any rate, I'm not suggesting to obliterate the thread, which doesn't happen anyway, just to "demote" it from being a sticky.
