Part of its purpose is a micromouse-robot control. Part of those reasons are for motor control, so I am an interested audience for Crenn's motor controller. I'm also interested in extending Raspberry-Pi.</p> <p>As I wrote, I am more interested in learning from others, than awards. IMHO, encouraging folks to share what they are doing with Maple/STM32 is a 'good thing'. I am a bit concerned that rather than encouraging new talent, awards might get dominated by "The Usual Suspects". The old adage about only getting what you measure suggest the choice of awards and the process is critical.</p> <p>I am happy to recognise what has been done. I am all for helping folks get into making, solving problems, creating products, learning, experimenting, and having fun.</p> <p>Could we also try to support each other more concretely in doing new things? </p> <p>If we are able to 'incubate' new projects the forum might attract as much energy, interest and knowledge sharing around new projects, as reports of what has already been done. (I haven't thought this through, just 'running it up the flagpole')</p> <p>I feel that there aren't many places for folks to get good help and advice on low-level development (there are extremely helpful folks like clive1, my hero, on ST's STM32 forums, however they seem to be exceptional). There seems to be little guidance on the net or in college (that I can find) about how to test and debug 'close to the hardware'. IMHO Stackexchange is uneven, but does have good mechanisms to help the process along. I think we try to get some of those ideas across, and there are enough eyes+brains reading threads that people usually get high-quality help. </p> <p>Summary: Awards seem to be fine for people who are likely to succeed anyway, however I am not clear how awards help people collaborate, improve, help others, and improve our quality of life, which are my stronger interests. That might be my cynical old fuddyduddyness, tainted by watching the Academy awards, or similar dross ;-) </p> http://forums.leaflabs.com/topic.php?id=10143#post-22128 Sun, 27 Jan 2013 10:32:13 +0000 StephenFromNYC 22128@http://forums.leaflabs.com/ <p>@crenn,</p> <p>When I first made the suggestion for a project (or thread topic) award I wondered if @gbulmer would win every time.

First off is my Raspbian Rover, all of the motors, sensors and displays are driven by a Maple Mini r2 which is a slave SPI device of the RPi, nothing too exciting really. I'm also working on making an alarm clock and temperature datalogger using a 3.2" TFT display, I'm looking at later making a 3D printed case for it and integrate a LiPo battery charger into a PCB that utilises the STM32F1 (or F3 if it's cheaper, means a little more work though to port libmaple to the F3). I'm also working (loosely working more like it) on libraries to drive the TFT display more easily using adafruit's libraries, although I know others on the forum have done this previously although I need a custom library due to the fact I'm using a 16-bit port expander (MCP23S18) to drive the data lines, I'm actually writing a library for that as well. Trying to make writing data to the MCP23S18 as easy as writing to an internal register (it's going to be interesting if it actually works).</p> <p>I'm still toying with the idea of making a brushless DC controller, although this will be possibly based around a PIC or AVR depending on the form factor. I'm thinking of trying to make a stepper motor replacement using a brushless DC motor, mainly for 3D printers.</p> <p>You shouldn't forget about nully's work making a 3D printer driver board: <a href="http://forums.leaflabs.com/topic.php?id=10140" rel="nofollow">http://forums.leaflabs.com/topic.php?id=10140</a> Although it's more recently, I'm impressed by the simiplicity of the design and wanting to play with it myself when I finally build my 3D printer. </p> http://forums.leaflabs.com/topic.php?id=10143#post-22119 Sat, 26 Jan 2013 08:37:41 +0000 gbulmer 22119@http://forums.leaflabs.com/ <p>I think there are all sorts of interesting, helpful and useful things where we have some inkling of the outcomes.</p> <p>Xavier did an FM Synth using Maple (Mini) <a href="http://forums.leaflabs.com/topic.php?id=665" rel="nofollow">http://forums.leaflabs.com/topic.php?id=665</a><br /> ala42 has done some lovely work, ported libmaple to STM32F4, and designed a 'copter controller<br /> Siy did several great boards mentioned initially I think here: <a href="http://forums.leaflabs.com/topic.php?id=1284" rel="nofollow">http://forums.leaflabs.com/topic.php?id=1284</a><br /> xpomvid made a quadcopter using Maple: <a href="http://forums.leaflabs.com/topic.php?id=2239" rel="nofollow">http://forums.leaflabs.com/topic.php?id=2239</a><br /> Cren has worked on several parts of libmaple and SD cards<br /> bubulindo has worked on making the built-in RTC usable<br /> feurig &amp; co. have made all those healthy Maple alternatives :-)</p> <p>I am sure I am forgetting lots of other contributions, but these easily spring to mind.</p> <p>However there may be many more projects that we never hear about. </p> <p>I remember questions about brushless DC control, controlling a real engine, decoding Manchester encoded signals, how fast can pins be toggled etc. I don't know what eventually happened, and I am curious. </p> <p>I am more interested in understanding what people have made than trying to identify 'favourites'. If folks will give more feedback to the forum because of 'favourites' bake-offs, then that is helpful to me.</p> <p>(Full disclosure: I am not a member of LeafLabs staff.) </p> http://forums.leaflabs.com/topic.php?id=10143#post-22106 Fri, 25 Jan 2013 17:48:59 +0000 feurig 22106@http://forums.leaflabs.com/ <p>I dunno @joeferner has done what most of us should have done a while ago.

This could be done once a year, or maybe two or three times a year if there are enough "nominees". It would be a simple way to give recognition to the users whose questions, topics, or projects have provided the most momentum to the LeafLabs class of microcontroller boards.</p> <p>Any thoughts? </p>
