Come on! This is the 21st century, whipping up an Arduino based datalogger is just as much "Making" as building a super regen receiver using tubes, carbon resistors and a solder gun were back in the day. > Well, sometimes it does happen!

You can make a bomb without a clock, but you can't make one without explosives. You'd think that the cops would have noticed that, but, then again, maybe not. I hope those cops never come around to my house, they'd probably think that it was a terrorist bomb factory, what with all the circuit boards and wiring lying around. |

And do you think the CIA won't inspect that "clock" closely when it arrives at the White House? Hey Mister president, "can I bring my clock? Um, your not worried that I would bring a bomb are you? On entry to the white house, we need to check your clock, "why, it's a clock! But we need to verify that. "You mean like my teachers?" I'm sure the reaction would be severe if I tried to carry that (clock) into the white house. Mikek |

No one has ever said the kid had a bomb. The first teacher he showed it to said that it looked like a bomb and to put it away and not show it to anyone else. The kid took it to another teacher and plugged it in the wall so it would alarm during class. He was questioned by teachers and by the police about whether he brought the clock in to make it look like a pretend bomb, which is still a crime. https://www.youtube.com/watch?v=pzUtR5TvuzQ Here is the mayor saying that law enforcement and "numerous" teachers are receiving death threats over the incident. I have yet to see a single report about death threats on the news. It seems that death threats from the "religion of peace" do not fit the MSM narrative. https://www.youtube.com/watch?t=198&v=weTqNxXHLRk |

bitrex <bitrex@de.lete.earthlink.net>: Sep 28 03:06PM -0400 Here's the service manual for reference: http://www.loscha.com/scans/Korg_MS2000_Service_Manual.pdf I replaced C109 with a 100uF electrolytic temporarily, and also found that the power and ground planes were shorted together. Common mode choke L10-L12 had apparently burned and shorted, so I've temporarily replaced it with jumpers. The +7 and +5 rails are up and running now, but the 3.3 volt rail is still down. I measure about 8.6 volts from positive to negative across C109, but I'm also seeing about 8.7 volts from the ground terminal of C109 to the ground fin of regulator IC7. |

There's no continuity between the top of C25 and where C50 would have been. Guess L13 is smoked as well.. :( |

Guess L13 is smoked as well.. :( The schematic shows that L10, L11, and L13 are NU (Not Used). L13 is replaced by a jumper. Is the schematic for your unit accurate? |

I believe it's accurate, I was just being dumb. The common mode choke was just 2 windings - it was scorched and shorted. I cannot find L13 anywhere on the board. Still, there seems to be a continuity problem somewhere as the buck switcher is not getting an appropriate input voltage. I think I'm first going to take the other poster's suggestion, disconnect the switcher completely and see if I can get the logic working off a bench supply, as if I can't get it operating that way then this exercise is really for nothing. |
N_Cook <diverse@tcp.co.uk>: Sep 29 10:39AM +0100 Unusual package, I can get hold of the usual 1.25mm pin spacing SMD 8 pin SOIC IC . I might be able to find an exact replacement if I knew the SMD style code for .75mm spacing, normal width of SOIC IC body but not so long. May be about .75mm pitch , not exactly .75, only ruler measurement. At a pinch I might be able to twist 90 degree each pin axially and realign for the smaller pitch, and/or grind back the pin width with .5mm dremmel discs, but very constrained space and an exact replacement would be a lot easier. |
N_Cook <diverse@tcp.co.uk>: Sep 29 11:26AM +0100 Oddly its wider than normal SOIC. Tried grinding and bending pins of a practise 8pin SOIC and that will work, but I'd like to obtain a proper footprint replacement, if anyone knows the style, something like QSOP. |
N_Cook <diverse@tcp.co.uk>: Sep 29 11:36AM +0100 perhaps TSOP type II, .8mm pitch. |

Smarty <nobody@nobody.com>: Sep 29 05:18AM > He was asking questions about using his Apple computer for video > editing. > That doesn't really add up to me. Blindness is not a binary condition. There are a wide range of deficits including a somewhat arbitrary "legally blnd" state which differs from one country to another. There are those whose blindness may be principally in color perception, night time vision, peripheral vision, etc. The bottom line is that video editing and many other tasks which rely on vision can be performed by those individuals whose medical and / or legal situation is accurately described as blind. |

The big question is will they be compelled by the state or > feds to do this or will this be be treated as just another recall. You won't be able to ignore it. The EPA has a LOT more power than the NHYSA does. They will simply blacklist the VIN numbers of all the vehicles that are not in compliance with the regulations. Owners will probably get a letter telling them that they have XXX days to get to a dealer and have the fix done. If they don't they will get a letter from the Feds telling them that they are driving a non-compliant vehicle and that the registration has been suspended. -- Steve W. |

Since September 2013, 2000 and newer vehicles no longer get tested on the dynamometer and no longer get a probe shoved up their tailpipe. The whole test is done via the OBD-II port (as well as a visual inspection). For diesel vehicles you can see the details here: <http://www.smogtips.com/diesel-smog-test.cfm> So clearly VW was not just looking at wheel rotation, they probably turned on the emission controls whenever they detected something reading the sensors. I wonder if an ELM327 transceiver or a Progressive "Snapshot" would have any effect. |

The way I see it, it's just another recall and the feds should just grant an exception for the victims of this scam. I think that's an easy solution to this problem. |

It seems CA has portable roadside emissions checkpoints that measure the emissions as you drive. I wonder why they haven't seen a major problem with VW vehicles as they pass these checkpoints? Maybe it is a minimum difference between a properly working system and a VW in the fuel economy mode? Like someone else said - is the nominal emission near zero and 10 to 40 times worse is still an extremely small amount of NOx. |

But they should be 6uF caps. Back to back, they will test out at 3uF. If you screen them carefully, you should be able to get very close to the 2.7 you need. Or, use 2.5uF caps as electrolytics tend to run 'fat' rather than 'lean'. Or, use a film cap, full stop. http://www.mouser.com/ProductDetail/Cornell-Dubilier/DME1W2P7K-F/?qs=GfXtfMhyVhhkUS5OI4XuCw%3D%3D&gclid=CjwKEAjwyqOwBRDZuIO4p5SV8w0SJAAQoUSweNlsFGU9403jEo7URCsx-ZcaR5IPgoCvR4HfbhMJjxoCKrrw_wcB&kpid=3343101 Polarity will not be a problem.
