Especially the parts I couldn't have thought of or executed myself! --- End quote --- Thanks mate, I've been looking at your curvy little marvel in particular your use of materials, in some ways similar to my approach to some of my cabs. Great use of materials and methods..Look forward to seeing more. I have a lot of fiberglass work on my horizon. It's hard work but the results are very nice. I know the apparent transition from rough wooden box to coated enclosure looks a bit unreal. It's just me being a bit cheeky and sparing you all the finishing work that went on in between. The wooden box had added to it sheet metal 'grills' that are slightly set into a rebate, worked over with Bondo fill and then Primer/filler coats. That last process is repeated several times to achieve the smooth looking finish prior to applying actual black paint. These days I only use my spray gun and compressor to paint with. In addition to the grills (and using the same process) I added the metal bezel for the display. The enclosure is thin and vented where it needs to be and thicker and sturdy over the rest of it. It's a system that I've refined more and more over the years but it all goes back to my arcade cabinet building adventures. @ Zebidee - very observant! Yep, that is a genuine Singer sewing machine manufactured in 1928. It has been in my family since new. It was my grandmother's originally and is now my youngest daughter's. It just needs a belt from the foot pedal, otherwise works fine. @ fablog - The phone, a Samsung Galaxy Note 3 underwent various hacks. Firstly I replaced the standard OS with LineageOS, rooted and minimal app install including the Kodi remote app Yatse. I removed the battery and replaced it with a dummy blank that provides the phone with power from a regulated supply I built for the purpose - using a variable regulator and other parts: This fools the phone into thinking it has a near full battery that will last for EVER. The final hack was to solder a switch cable under the main board of the phone to allow a power switch for the phone on the rear of the enclosure: The phone only needs to be switched on once when the Media server is plugged in. Thereafter it just sleeps when the unit is powered off. Hit the on button on the remote and everything just switches on. Just some fun before the serious business of arcade cabinet building resumes... 8) |

Is there a couple of resistors to set the voltage and a cap on that breadboard in addition to a power button? I want all the gory details of course. --- Quote ---The phone only needs to be switched on once when the Media server is plugged in. --- End quote --- There is a "trick" that might work so that the phone comes on when the media server is plugged in, all at the same time. You put a capacitor across the phone switch terminals (paying attention to polarity) to simulate a button release. As you power on, the capacitor will be initially closed and circuit pass current, like you are pressing the button. Once you power up over "some milliseconds" the capacitor will charge up and circuit becomes open, like you have released the button. The fun part is to find what capacitor to use. Around 1 - 10uF is good for PCs (you can also set this in BIOS for most modern PCs so not always useful these days). For the Loewe TV I have in my vertical cab, I use a 100uF cap. This works because the larger the caps the longer to charge, you just need to choose appropriate value to give the supporting control system enough time to wake up and thus recognise the (fake) button press. |

Master of fit and finish as always. :cheers: |

I don't think I need one of these but man that looks so nice. I just upgraded my phone and have a spare Samsung Galaxy S9+ laying around too. My problem is I don't think I want to re-watch the hundreds of DVDs I have lying around. I usually stream new content from my Tivo. But that looks fun to figure out and build. |

@ Zebidee - You are pretty close with the regulator tuning method. I don't have the circuit diagram handy but yeah it's just the variable regulator, one resistor, one variable resistor and a couple of caps. The var resistor provides the adjustment for voltage. I like your capacitor/momentary switch idea. I think if I did use that, I'd take it one step further and use the cap to open and close a relay for the switch instead. Again finding a suitable cap for the duration which is quite long for this phone. That way I'd isolate the cap from the phone altogether and it can just discharge through the coil. @ Badmouth - Hey buddy, we're still here and still building stuff! :P @ Gilrock - Thanks, yeah streaming the latest stuff is most peoples choice for movies (which this unit does also). I really like Kodi and it's various incarnations in particular the LibreElec version which combines a very minimal Linux OS with Kodi - boots fast and is very configurable. Video codecs are pushing into HD territory with H.265 requiring a bit more processing power than H.264. The other main reason for this is to store my music in one place instead of all my CD's, with good quality audio playback options. |
