        Hello Element14 community and others!

        I'm Nelson, as you may have guessed, and I'm really excited to be getting in to this whole world of making things do what I tell them to. I'm a novice when it comes to writing code, though I have a fair hand at a few scripting languages (bash and sh mostly, to be honest), and I think I might have once held a soldering iron briefly when I was a kid, but it wasn't on.

        I've ordered myself an Arduino starter kit, as that seems like a good place to start learning. It's really neat to see that there are so may other players in this community though. I look forward to learning the differences between them, and discovering what applications each platform may excel at, as well as discovering the projects that I find most fascinating.

          My name is Don.  I am retired, so my math and EE degrees are way out of date.  I was a programmer and analyst for 40 years, mostly in super computers.  Now I am interested in 3D printing.  I need to learn how to program these printers.  I tried cad-cam several years ago, but the learning curve was a little steep without a purpose.  Maybe I can learn from some of the members of this group.  By the way;  I understand there is a Yahoo 3D printing group, but I could not find it.

                Hi Don,

                 

                You will find a number of us old dogs hanging around the site.

                There is a lot of interest here about 3D printing and a number of them with good experience.  You should message Nate Chapman as he appears to be the most experienced.

                 

                Meanwhile, welcome to Element 14.  I look forward to interacting with you in the future.

                      Hi from Robert.

                       

                      Retired. Amateur Radio (KJ6HFR).  Self taught in electronics and programming. About 30 some years ago bought an S.D. Systems Z80 single board computer and stared at it for 6 months as I slowly taught myself assembly language.

                       

                      I’m more of a slow dabbler than someone who designs and builds “real” things (some of my projects are at: https://www.youtube.com/user/robrlstn/videos). Other than blinking LEDs, I did complete these 3 “substantial” learning projects:

                       

                      1. Test jig (“ClickerMedic”) where solenoids tap out a specific key sequence on a laptop. This device saved me from tedious manual testing of an RF audience response system when I worked at UCD. The hardest part was to mount the solenoids just right.

                       

                       

                      Both projects below are notes about “bit-banging” PIC registers, as learning exercises.

                       

                      Both use a PICKit2 Microchip programmer and its standalone application. Some code is hand-assembled using no compiler;  the remaining code uses the free version of Swordfish BASIC. Some experiments use a minimal breadboarded circuit while others use the HamStack platform from Sierra Radio Systems, although all experiments could be breadboarded without using any commercial board.

                       

                      Both projects were a result of learning to read the voluminous Microchip data sheets (400-500 pages per chip), to understand in a basic way the memory architecture, configuration bits, special function registers, and so forth.

                       

                      Both sets of notes are available on the Sierra Radio Systems / Project Gallery site (http://www.hamstack.com/project_home.html). (I’m not employed by Sierra Radio, just happened to buy their board at Pacificon).

                       

                       

                      2. 18F4620 CookBook Hands-on Experiments, to learn about the chipʼs hardware and software architecture: oscillators, resets, code protection, User IDs, Device IDs, watch-dog timeouts, memory layout, and specific control registers (SFRs).

                       

                      Surprise: all PICs I’d previously used wrap around from the end of on-chip program memory to the beginning, the reset vector. But this chip, at the end of on-chip program memory, advances the program counter through all of the unimplemented user memory space, all instructions executed as NOPs, before wrapping to the reset vector (details in the CookBook) !!

                       

                      These approximately 968k NOPs provide a visual delay when implementing a blink-a-LED Hello-World program with 2 instructions.

                       

                      These notes include a 12 instruction (using the WDT) cylon eyes “homage” to Smiley Joe Pardue, a Nuts and Volts writer, where I first learned about cylons.

                       

                       

                      3. PIC PWM with forty+ experiments including basic PWM generation, varying duty cycle and period, enabling multiple CCPs, enhanced functions such as half-bridge and full-bridge, slew-rate limiting, steering, and servo control.

                       

                      I was building a “Dial-a-Color” board: 3 rotary encoders would control the PWM drive to an RGB LED through a PCA9685

                      (16-channel, 12-bit PWM Fm+ I2C-bus LED controller). In wasting 13 channels, I kept wondering if the 18F4620 or 18F46K22 had enough hardware PWM capabilities to do this, resulting in the PIC PWM experiments.

                       

                      Future projects might include studying the ADC peripheral in the PIC, building something better than my YesNoBox using the ISD1932 voice recorder from SparkFun, and maybe finally trying to learn C and the MPLABX IDE.

                        Welcome Robert. My name is Devin. Im sort of new to this side of computers. Ive been building PCs for years for gamers. I have met some of the nicest people here that work for element14/Newark. Im sure you will have a good experience, I know I have. They are great.

                          Thank you Devin.

                           

                          Since you build PCs for gamers, is it fair to say that the primary concern is to have a video card with enough processing power?

                           

                          Having seen the very first video cards in IBM XTs and such, it surprised me to hear about GPU and the enormous compute power on graphic cards.

                            That would be top 3 for sure. Right along with overall RAM and a good CPU. I have found that AMD is much more suited for gaming than Intel. They are more easily overclocked and to me seem to produce less heat.

                              Hi Robert,

                               

                              It sounds like you are on your way to learning the wonderful world of micro controllers.

                              If you did any custom builds for your amateur radio days, then you should find the transition pretty easy.

                               

                              Plus you will find all kinds of people here at Element 14 who are willing to help, so ask questions and you should find all of the help you need.

                                  Hello Daniel, Im Devin. Im jyst a member here, I dont work for element14 but I like to welcome foljs because I was made to feel welcome when I joined. I dont even qualify as a novice yet but I am very excited about learning. I was brought to the community by watching Ben Heck, I love his builds and hope to use his luggage build to design my own astromech. I just got my first Raspberry Pi in the mail today and have been playing with it already. I hope you have fun here  and remember to ask questions and join groups and use the knode for research.
