OK ... tell me how you'd get something milled or engraved on a student's budget? Of course, student budgets may be considerably larger in the U.K. and Europe than here in the U.S.


Not sure how it is in the US, but at the UK university I went to they had a Mechanical Engineering department with a complete machine shop. I'm sure I could have found someone to help me there if I needed and if I wanted to take that approach.

Student project idea?            01/01/70 00:00      
   Being German in Nature...            01/01/70 00:00      
   rather costly for a student project, isn't it?            01/01/70 00:00      
      not necessarily            01/01/70 00:00      
         Dont you think that would be too difficult for a student?            01/01/70 00:00      
            Why moving-message?            01/01/70 00:00      
               How can he display all the text?            01/01/70 00:00      
                  Then you've entirely missed the point!            01/01/70 00:00      
                     BTW: It actually does 1 minute resolution            01/01/70 00:00      
            Moving ????            01/01/70 00:00      
               Maybe you could be more specific            01/01/70 00:00      
                  Why so specific?            01/01/70 00:00      
                     but entirely too expensive ...            01/01/70 00:00      
                        who gives a friggin hoot            01/01/70 00:00      
                           and how does your 8x8 array apply?            01/01/70 00:00      
                        Up to student to decide cost.            01/01/70 00:00      
                           Other options            01/01/70 00:00      
                              Interesting ... how does the student do that?            01/01/70 00:00      
                                 I'm sure they'd figure that out...            01/01/70 00:00      
                                    Maybe you can enlighten me            01/01/70 00:00      
                                       Mechanical Engineering            01/01/70 00:00      
                                          Yes, that's the kind of thing.            01/01/70 00:00      
                                             I once had a complete machine shop too ...            01/01/70 00:00      
                                                what sort of engravers/routers do you mean? [edited]            01/01/70 00:00      
                                                   We keep forgetting about the costs            01/01/70 00:00      
                                                      Old news            01/01/70 00:00      
                                                         Apparently things have changed.            01/01/70 00:00      
                                                         eMachineShop.com ?            01/01/70 00:00      
                                                            Maybe            01/01/70 00:00      
                                                               Another option ...            01/01/70 00:00      
                                          Darn straight.            01/01/70 00:00      
                           look at the model again ... there is no matrix            01/01/70 00:00      
                              of course there is            01/01/70 00:00      
                                 but it's not the 8x8 LED matrix ...            01/01/70 00:00      
                                    One LED per character            01/01/70 00:00      
                                       If not cheaper than at least way faster            01/01/70 00:00      
                                       Gee ... I'm not sure I follow ...            01/01/70 00:00      
                                          Simple, simple, simple            01/01/70 00:00      
                                             Why multiplex ... there are so few words ...            01/01/70 00:00      
                                                Really is applicable            01/01/70 00:00      
                                                   Wait a minute ...            01/01/70 00:00      
                                                      I never did            01/01/70 00:00      
                                                         well, then, you should clarify            01/01/70 00:00      
                                                            proof of concept, not product            01/01/70 00:00      
                                                               Backpedalling on what?            01/01/70 00:00      
                                                                  Tiny budget for tiny clock            01/01/70 00:00      
                                                                     Now go to the next step ... the word arrangement            01/01/70 00:00      
                                                                        I did my best            01/01/70 00:00      
                                                                           I caught that only after I asked            01/01/70 00:00      
                                                                              Many, but quite simple steps            01/01/70 00:00      
                                                                              At last!            01/01/70 00:00      
                                                                                 I wasn't asking you , Andy ...            01/01/70 00:00      
                                                                                 I believe you overestimate the challenge, Andy            01/01/70 00:00      
                                                                                    Not a first-year project            01/01/70 00:00      
                                                                                       I'm not so sure ... maybe I'm out of touch ...            01/01/70 00:00      
                                                                                    RE: I believe you overestimate the challenge            01/01/70 00:00      
                                                                                       You'd be right ... except ...            01/01/70 00:00      
                                                                                          Trivial?            01/01/70 00:00      
                                                                                             Those may not be as important as you think            01/01/70 00:00

                                                                           have you counted lines and characters            01/01/70 00:00      
                                                                  Not spinning-arm display printing in air...            01/01/70 00:00      
                                                                     are you missing a critical word?            01/01/70 00:00      
                                                                        The word you require is...            01/01/70 00:00      
                                                                           Oh! OK ... that works.            01/01/70 00:00

                                                         This is where you should explain a bit more            01/01/70 00:00      
                                                            overly complex            01/01/70 00:00      
                                                               I don't see it as overly complex.            01/01/70 00:00

                                                            I don't see how multiple LED's per character help anything.            01/01/70 00:00      
                                                               That seems reasonable            01/01/70 00:00

                                 That looks like the most straightforward way to do it!            01/01/70 00:00

                              once again, who gives a hoot            01/01/70 00:00      
                                 Shouldn't a "proof of concept" demonstrate feasibility?            01/01/70 00:00      
                                    What nonsense!            01/01/70 00:00      
                                       Good project - relatively easy but much room for own ideas            01/01/70 00:00      
                                          what the hell is REAL company???            01/01/70 00:00      
                                             A real company            01/01/70 00:00      
                                             Not at all!            01/01/70 00:00      
                                 No matter how well it works ...            01/01/70 00:00      
                                    That would be a very bad professor            01/01/70 00:00      
                                       Unfortunately, you're wrong ...            01/01/70 00:00      
                                    What nonsense!            01/01/70 00:00      
                                    Look at some real examples - "Made In Brunel"            01/01/70 00:00      
                                       These items most certainly are well-finished            01/01/70 00:00      
                                          Exactly            01/01/70 00:00      
                     Not all the characters are used            01/01/70 00:00      
                        8x8 modules don't care about unused characters            01/01/70 00:00      
                           other arrays are cheaper            01/01/70 00:00      
                              Depends on expectations of total size            01/01/70 00:00

         Yes, designer niches allows very high prices            01/01/70 00:00      
      Do you really think that manufacturing costs are low?            01/01/70 00:00      
         That's why I was complaining about cost!            01/01/70 00:00      
            You forget the costs...            01/01/70 00:00      
               Not exactly ...            01/01/70 00:00
