| Freeple <Freeple@Freeple.com>: Aug 04 06:16PM -0700 Any thoughts would be appreciated. Jazzy Select was driven into a hole and then it just quit. Controls light up but will not go. Wheels locked up. Could not push. Yes, the release was thrown on both wheels to allow easy pushing. Circuit breaker on the front to the Jazzy was not popped but tried to reset anyway, several times. Jazzy Select was loaded on a furniture dolly and given a good shake on the asphalt road while getting it home. When home, the wheels turned freely and was easy to push. What happened here ? Engaged the wheels but the electronics on the arm rest throws a 9 blink error code. Means a bad connection to a motor. Let it sit a few days while I researched and found nothing helpful. Opened the Jazzy, disconnected the batteries and pulled the controller box so as to get access to the tight connectors. One to the control stick on the arm rest and two more, one for each motor. I inspected the connectors, both sides and found absolutely nothing wrong. Clean and almost like new. Plugged it all back together and, the darn thing started working. Seems to be normal operation. Any idea what might have happened and what fixed it ? Just re-engaging the connectors ? Maybe ? |

Maybe ? As it happened during violent action, (driven into a hole) and you got a bad connection error code I'd say the bump caused a bad connection that was fixed when you disassembled and reassembled the unit. It has happened to all technicians, take it apart, put it together and it works. It's working, you can't trouble shoot it. If you are a repair shop, the question is, do you charge high expecting you will get it back and have to repair it free. Or charge a low fee and then have the customer pissed that they have to pay twice for the same repair. Damned if you do and damned if you don't! Mikek |

The PROBLEM is that customers regularly fail to understand that ALL defects with their equipment BELONG to them !!! Ownership does not change when they present the item for repair. Same goes for anyone offering to help someone, like Doctors and Lawyers. Neither if these guarantee to fix your health or legal issues - all they need do is make a reasonable effort. You pay for their time regardless of the outcome. ..... Phil |

Yes, the release was thrown on both >wheels to allow easy pushing. Some chairs and scooters have tilt sensors to disconnect and lock the motors if the chair is in danger of toppling. The newest models will go up or down and incline as much as 15 degrees from vertical, and about 10 degrees to the sides before killing the motor. The user manual recommends 6 degrees (10.5%) maximum slope. The chairs with a very low center of gravity can tilt more before shutting off. Some also include anti-tip wheels and forks. What I don't know is if your unspecified model Jazzy Select has this feature and exactly how it works. I couldn't find anything definitive in the manuals or on the web. >Jazzy Select was loaded on a furniture dolly and given a good shake on >the asphalt road while getting it home.

Ok, loose connection. >Seems to be normal operation. >Any idea what might have happened and what fixed it ? >Just re-engaging the connectors ? Maybe ? Congratulations. By unplugging the battery, you reset the alarm and the electronics. My guess(tm) is the shock of driving it into a hole set some kind of alarm condition that required either a manual reset or a power disconnect to restore operation. That's why I asked if someone unplugged the battery before transporting. I would not suggest driving it into another hole to test if it's fixed, but dipping it over (being careful to not dislodge the battery) might be a worthwhile test. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Maybe ? There is a micro switch on some models that will go intermittent that is located by the back axle. We had one that went dead and then started working where this switch was the culprit. The rubber boot doesn't adequately keep crud out of it. |
| N_Cook <diverse@tcp.co.uk>: Aug 05 04:56PM +0100 Firstly for anyone else playing with these neat cheap laser diode measuring devices. I'm initially playing with a (Lidl) Parkside PLEM 50 (50m range), to eventually use a Lomvum LV 120 (120m range) coupled to a pc via Pi/Arduino. Both have 4 line 7segment LCD plus annunciators display with a "chip on glass" look-up page chip for decoding and driving the LCD. Made by SZYCLCD.COM and ident YGFB178004-A1 on the .5mm spacing ribbon and I know by swapping between each, they are compatible between both devices , completely different external and internal appearance, but same STM micro. 14 way ribbon to LCD , 2 w for backlight, 2w for power to chip on glass and a number of apparently inactive lines in measurement mode anyway . So d0 clock , d3 and d4 used for SPI update principal lastline of LCD and d2 +d3 active during power-up/first page but not in measure mode. Breaking-out at the ZIF ribbon socket and using Hobbycomponents "matchbox" pulse analyser and Sigrok/Pulseview and pairs of readings on the lower line of the LCD, ie switch unit on, then just pressing "measure" once initiates the SPI clock pulses. The LCD is updated from switch-on display in 0.5 to 1 seconds , so the data must be contained within the first 2 or 3 frames of data. Short duration bursts of clock then various amounts of dead space , as much as 400mS between frames, highly variable duration. I was hoping the same as https://www.mictronics.de/2018/02/laser-distance-meter-hack/4/ LookupTableLcdLastLine.pdf , on link https://www.mictronics.de/?wpfb_dl=156 on seeing 17 4 bit words per frame (mainly, sometimes 13, sometimes 16) The first frame seems to have only 4 variants and is re-used for totally different last-line readings. Whatever I set sampling speed, clock polarity or phase etc I cannot avoid the "smearing" between frames ,eg 348-384 : 05 378-403 : 00 403-428 : 04 429-1961499 : 0C 980976-981002 : 0D 981001-981026 : 00 981026-981051 : 04 how to tidy up word apportionment ?. And then for pairs of metre/mm distance readings I cannot get any sense of pertinent words to decode/look-up (redundant 0's removed here for linwrap) and only frames 2 and 3 including the "smears" B1820 sequence looked promising as an ident but non appearance in one dataset. 00012080049008B180208010400A200 =6.345a 8B18020400108A000001208004900 =6.345b 8B180200010400A4000044041002101 =5.085a 000120A000504CD0401048082004202 =5.085b (B18020 sequence not appearing in any succeeding frame, well beyond 1 second) 00012080049088B180208010400A404 =1.564a B180200010400A400008010400A404 =1.564b -- Monthly public talks on science topics, Hampshire , England <http://diverse.4mg.com/scicaf.htm> |
