 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

exactly so.  SIN() also provides a gentle approach to the target by reducing the power more and more as you approach. There is a "nudge" value based on the demanded and ambient temperatures so that you don't get caught in a never-ending insufficient-power-input-to-achieve-demand position (it isn't linear). There is a bit of that visible in the plot as it stabilzes around 60W, but as it is <2% from the target °C and on the cool side, I can live with it. If it ever gets to the point that I can't then I can tweak the nudge just to provide a bit more, but risk over-shooting because now you can't back the power off enough before you get to the target. I really don't like that and the little bit you see in the plot where you approach the demand (100°C) early on at full power then back off irks me, although that is because I don't start PIDing early enough. This is all tied up in some horible complex ambient Vs demand Vs power algoritm, which to be honest is already to complex for what it's doing. Part of getting this right, is knowing when it is "right enough" and then leaving it alone before what is left of my hair bails too.  This is backed up by local hot-spots as well. no point fighting over this when the temperature varies by about 6° or more depending where you measure, e.g. right over the heaters or at the corners of the plate. |

G'Day Capt & Phil I never did understand control systems. I managed to avoid them until late in my career and then I was saved by a tutorial from Inland Torque Motors. However, I would have thought that there was enough in PID to do all that but as I said, I never did understand the things. Peter |

G'Day Peter. Yeah I am still pottering about, Thanks for me, process & control is a love/hate relationship It can be really infuriating but when it works it's a real buzz. Even simple requirements tend to become quite complex once you start breaking it into steps. I am minded of Mahler's response to the question in Max Headroom "how does it work?" to which he replied "You just turn it on and key things in" - if only it were that simple.  A few yers ago I built a garage controller, inside & outside lights, door automation, pipe heater for the winter etc. all controllable via Bluetooth and an app I did using the MIT app builder for Android. works nicely... but even just opening the door mushrooms into a number of steps and a ton of flags and timers so I know the state of the whole system at any one point. I did a sneaky thing with that too... the outside light is a mains strip of LEDs over the curtain - very bright, but I only want it on when it's dark and the door is open/ing/closing. So now time becomes a factor, and so does time of year as the daylight moves about... so now I need a clock in a system that doesn't have an RTC. What I ended up doing was in the Android app, every command is preceeded by the epochtime (unixtime) from the phone and the controller sets its date/time from that each time it gets a command and before it interprets that command - so called "Just In Time". So now when a door movement is demanded, I can tell whether the light is to be used too. I love control systems Edited 2024-05-13 18:07 by CaptainBoing |

Unfortunately not, though I have archived your links for future reference (thanks). I've talked about wanting an MMBasic Lode Runner clone in the past and I think @vegipete may even have posted a screen or two, but I haven't seen anything more.

Would love to see a good version of Lode Runner. It and it's sequel Mad Monks Revenge are among the few games I've played from beginning to end. I've placed it on my programming projects wish list. Unfortunately it is near the bottom of the list since I have none of the skills required to write the game.😞 --Curtis Edited 2024-05-14 05:24 by Justplayin I am not a Mad Scientist...

Hi Curtis and others, I have never played Loderunner, but many seem to have good memories of this game. Which makes it a very unrewarding project to do. It is hard -maybe impossible- to satisfy these nostalgic memories from so many people, and each one has it's own memories of the game. Graphically the game is simple, so the fond memories must come from game play, complexity, puzzles, speed, levels. And it will be hard to make that satisfy for everyone.

I have written a couple of games in the past and do know you need to have a real passion for games you write. My Pyramid Solitaire game took me a couple of years to find a bug which crashed the game if all the cards were cleared on the first pass through the deck. I'm still not 100% sure it's fixed since a perfect game is so rare. Anyway, a couple of months ago, I did download a bunch of different versions of Lode Runner. Since I'm not artistic, my hope was/is to be able to "borrow" some graphics if/when I decide to attempt my own version. I would worry about creating my own graphics once I got the core game working. --Curtis I am not a Mad Scientist... It makes me happy inventing new ways to take over the world!! |

Can't say I've sensed any clues but I do feel it's the calm before a matherp storm Personally, I couldn't be happier....Recent developments (thanks again, Harm) have opened-up all kinds of possibilities. Just need to clone myself.  |

@Curtis, This is by no means complete, but see this tread. The basis is there... Just need to finalize it... LodeRunner Regards, Volhout PicomiteVGA PETSCII ROBOTS |

I've done a lot more work on LodeRunner since then. Don't put effort into that demo. I'll post an update if desired. Visit Vegipete's *Mite Library for cool programs. |

Even though Lode Runner is a low priority for me right now, I would love to see your current update. My current high priority projects are my garage door monitor and my new MAX7219 matrix LED modules. Effectively I'm retired now and it still seems there is never enough time for all the things I want to do.🤔 --Curtis I am not a Mad Scientist...

Hi Pete, We are interested in the LodeRunner progress... If you feel you are at a level where you can share it with us, I will definitely look at it. Volhout PicomiteVGA PETSCII ROBOTS |

I have a few projects on the go (doing a round robin between them). Project #1. Recently I've come to think that part of the fun with retro stuff is being able to handle and touch things rather than just scrolling through menu's of stuff (music/games etc.). To this end I've built a little RFID reader hooked up to an ESP-32 - which in turn pretends to be a USB keyboard. I've hooked this up to my arcade machine and made a bunch of little plastic tags (one for each game). And now when you want to play a game, you have to dig out the tag and insert it into the arcade machine - like a disk or ROM from the old days.  I'm really happy how this has turned out. It really does give a new feel to playing the arcade. Oh - yeah - I also had to write a custom front end for MAME to interface with the new reader. The only thing left is to 3-D print a case for the reader. Project #2. Every year we have a pub crawl on our street where we change our garages into themed pubs. Last year my kids and I did "Barbie" and one of the neighbours very kindly made me a huge Barbie photo booth. This year, he's doing a Star Wars themed pub, so I thought I'd return the favour by building him a sit in Star Wars arcade cabinet (out of wood and cardboard). But for the internals, I'm using an old Nintendo Wii (one of the early ones that could read Gamecube disks) and a copy of Star Wars Rouge Leader that I got off E-Bay. The Gamecube controller is a bit small and fiddly to use in the arcade, so I found an old PC joystick (with the 15-pin D connector) in a thrift store. The problem here is that the X-Y pots on the PC joystick are 100KΩ, but the Gamecube controller pots are 30KΩ. So I'm building a little adapter board using an ESP32 that reads the 100KΩ Joystick pots and then outputs (via a programmable variable resistor chip) 0-30KΩ directly into the Gamecube controller. Now, the PC joystick should look like a Gamecube controller to the Wii. There's probably an easier way of doing this, but I'm having fun mucking around. Project #3. With the CMM2 I am working on a new game. I'm quite excited about it - but it's a long way from completion. |
