    Upcoming Major Changes and Updates to the ES Site

    At the time of the original forum buyback in 2011, there was a question of everyone simply jumping ship and launching a new forum with a new domain, as endless-sphere.com was simply a relic from the person who hosted the site on a domain intended for his private business. I had proposed offering...

    Upcoming Major Changes and Updates to the ES Site

    Updates to the content layout:  The structure of the various forum topics on ES doesn't always reflect how we want to have posts content organized. There are some categories that are way overused, others that are barely used, and often quite a bit of ambiguity in where a given topic should get...

    Upcoming Major Changes and Updates to the ES Site

    So here's where things get most exciting. As you're likely aware the phpBB backend on which ES is hosted is quite dated and long out of development. After a few mis-starts with other platforms, Neptronix settled on XenForo as being the best modern web software to handle the needs of our...

    Upcoming Major Changes and Updates to the ES Site

    Fortunately, the guy you know as Neptronix stepped up in a massive way, first helping out with many of the IT/hosting challenges of the site and then a large part of the management and moderation too. It's an enormous (mostly) volunteer effort to keep the site going as it has. But the...

    Upcoming Major Changes and Updates to the ES Site

    Hey everyone, I'm posting here for a long time update on the ES platform. First a quick background synopsis since there are plenty of people who weren't around for what is now ancient web history. Origins This forum was created in 2006 after the then popular V is for Voltage website...

    Cycle Analyst V3 preview and first beta release

    Glad to hear this did the trick for you! In the case of a bottom bracket torque sensor this setting doesn't do anything other than becoming the threshold to clear a torque sensor fault if the torque signal was high when the system is first powered on. But when you have a wheel torque sensor...

    Cycle Analyst V3 preview and first beta release

    Hey Ham, yeah as long as there is pedal cadence detected then the CA3 will continue outputting PAS power. But you can definitely set it up so that below a certain pedal effort the computed PAS output power falls down to zero watts. In the CA3.15 and earlier firmware, the setting PAS -> Strt...

    Ha ha I hadn't thought of that angle but what a great reply to "does it recharge when you pedal??" ! :lol: Cool, I'm interested to hear more firsthand user feedback on this and what your use case is. One important update for the regen speed limiting is a new global "Gain Adjustment" for all...

    Cycle Analyst V3 preview and first beta release

    Yeah I follow OS hardware / software projects with some interest to see when and where this approach makes sense. But the current CA3 codebase and architecture just isn't suitable for that model. It's all highly optimized 8-bit assembly and takes even a seasoned low-level firmware guy a few...

    Cycle Analyst V3 preview and first beta release

    One trick is that you can see the default for any setting with the setup utility software just be creating a "New Setup" and choose the appropriate firmware version then scroll down to the setting of interest. The values in the SU software are the same as what is flashed by default on the CA In...

    Cycle Analyst V3 preview and first beta release

    I will try to catch up and reply to many older posts from the last few pages of this thread this week. However, I first wanted to mention with an extremely sad heart that the former ES user Teklektik passed away earlier this month after a battle with cancer. People on this forum will know him...

    Cycle Analyst V3 preview and first beta release

    Ha ha sweet, and glad to hear that this has found it's some happy users and I really apologize for how long it took to get this particular behavior released. We had a branch on it back in ~2015 or so when THUN sensors were the most popular model with their single side torque sensing, and back...

    Cycle Analyst V3 preview and first beta release

    Hey everyone and sorry indeed that I haven't posted anything on this thread to keep people updated about CA development and I'm encouraged to see that there is still quite a substantial interest and following and that the CA3.2 features have been quite well received. We did a short video...

    Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

    For sure. We've got a batch on order and are just working out how we can go about connectorizing them to be more suitably plug and play with the hardware on an ebike since the built-in large automotive style molex plug is such a bugger to deal with for the various cables. What I did in this...

    Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

    Yeah, it's such a world of difference! I really have gone from a total FDM printer skeptic to a true believer after we got this in our shop. The unit we have is from a local Vancouver company called Pantheon Design: https://www.pantheondesign.com/high-speed-3d-printing They started off more as...

    For a spoke magnet system you need to make sure that the #poles setting is at 1, and not the default value of 23. Can you confirm if this was the case? It is protected by a PTC, so feel free to trip it as much as you like! One small detail to note is that higher currents in the DC jack do...

    Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

    But the best part is how well all the solar system came together. I had set my plans for our end of August summer vacation to be a sailboat trip from Vancouver to my family home in Sooke, which is about 160km away and double the range of the electric drive. So the hope was to install enough...

    Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

    Hey Guys and sorry about the seriously long lack of updates, and of that there has been plenty! As you can see in this video we finally updated the controller to the ASI BAC2000 device to run up to 5kW and as expected this brought the boat right up to hull speed but also got the motor right up...

    Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

    Oh nice, I like that they provide pretty meaningful consumption statistics. In this case it's a 1800kg boat and with enough motor power to get on a plane. Here's what I extrapolate for their wh/km consumption data as a function of boat speed: I managed to get our sailboat running at 5kW...

    Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

    PS, we finally finished editing the video from last fall showing the boat running at 72V earlier this week 4kAsdIiD8d4 I'll have pics and details to share soon with a new ASI BAC2000 motor controller installed that will let us run up to the 5000 watt power levels, and hope to do water tests on...

    Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

    I mean the math is pretty straightforward with the number's I've published earlier. If there wasn't a sail and then no need for a weighted keel either then the boat would be lighter and have a lower power requirement for a given speed. This sailboat has about a 5000lb displacement of which...

    Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

    Wow, I can't believe I didn't come across this project yet! That is a mighty purpose build solar boat of there ever was one. But it's surprising to see that in spite of that and with so much solar and what should be such a fast cat hull it looks like it was still only averaging 4-5 knots. I...

    Shamrock, 25 foot sailboat electric conversion with an ebike hub motor

    Yeah it's a great thing to wonder about. Part of the later phase optimizations was going to be seeing how much we could change this wh/km vs speed curve with different propellers, and using a CNC mill to machine prototype aluminum props that would at least last long enough in the salt water for...
