Berth Posted June 23, 2014 Share #22 Posted June 23, 2014 I guess I'm a lucky guy, otherwise I'd still be waiting. Link to post Share on other sites More sharing options...
dant Posted June 24, 2014 Author Share #23 Posted June 24, 2014 I wonder why they thought it useful to tell us that the battery was 80% charged but left it rather vague as to when it was fully charged. Yes that and the blinking lights are confusing. I am used to simple chargers. Link to post Share on other sites More sharing options...
Berth Posted June 24, 2014 Share #24 Posted June 24, 2014 Blinking light if charging. Solid light if fully charged. Complex? Link to post Share on other sites More sharing options...
Exodies Posted June 25, 2014 Share #25 Posted June 25, 2014 Blinking lights are very annoying, just as blinking text is. If your glance isn't long enough you can think it's off or on. Nobody is saying the current signals are impossible to interpret; they're simply badly designed. Link to post Share on other sites More sharing options...
paulsydaus Posted June 25, 2014 Share #26 Posted June 25, 2014 It is a poor design and had me confused the first time too. For something as simple as charging a battery you'd think it should be immediately obvious without even plugging the thing in or reading the manual. With the premium they charge on that thing it's not like an extra led couldn't have been included... Red, charging, amber, 80%, green 100%. Simple. It's amazing hour poorly some things are designed from a human factors viewpoint. Link to post Share on other sites More sharing options...

It's amazing hour poorly some things are designed from a human factors viewpoint. Perfectly confusing to me. Should be: Green=running. Red=stopped (charged). As in traffic lights. :-) BTW, they did include an extra LED light. None of my other chargers sports two lights. I have attached a sticker with the number 29 to my M. I have taken to numbering the bloody battery chargers so that I find the matching one quicker. Some of them flash while charging and light steadily when charged. Some light steadily when charging and flash when charged. Some flash when charging and are dark when charged. Some ... So what. Either put a sticker on the charger which reminds you how it indicates what. Or simply watch what it's doing when you plug it in and presume it's done when it does something else. Or wait for eight hours (i.e. overnight) and use the battery. Or delegate the charging of the batteries to your valet. Link to post Share on other sites More sharing options...
paulsydaus Posted June 25, 2014 Share #28 Posted June 25, 2014 I don't agree but each to their own. I do this stuff for a living and those a standard colour schemes used widely throughout electro-technical industry. I.e. Red used for power on, the device is charging/active/on load. Green for healthy normal condition (fully charged, no longer charging) and Amber or yellow for alert or informational condition. I agree, consistency is better regardless of what colours you choose.

farnz Posted June 25, 2014 Share #32 Posted June 25, 2014 It shouldn't make any difference as long as the driver can tell a lit aspect (lamp) from an unlit one because the message is also communicated by the aspect's position on the signal.

farnz Posted June 25, 2014 Share #34 Posted June 25, 2014 … except that it is because that's the system that's been used in every national railway system throughout the world since semaphore signalling was superseded. Are you suggesting that railway signal aspects or road traffic signals are insufficient on their own to safely control the movement of traffic? Pete.

Exodies Posted June 26, 2014 Share #35 Posted June 26, 2014 No. Both rail and road coloured signals also include a clear positional element together with mandatory training in reading them. A traffic light with one bulb which changed colour would be unsafe. Link to post Share on other sites More sharing options...
pop Posted June 26, 2014 Share #36 Posted June 26, 2014 However, in street signals the amber light may be on or flashing, which means something different, at least here in Switzerland. Link to post Share on other sites More sharing options...
farnz Posted June 26, 2014 Share #37 Posted June 26, 2014 No. Both rail and road coloured signals also include a clear positional element together with mandatory training in reading them. ... Regrettably your premise doesn't hold true throughout most of the UK railway because 4 aspect signals are used (colours read from top to bottom) Yellow-Green-Yellow-Red. There are two Yellow aspects that indicate to a driver whether the section of line after the section protected by the signal is clear or the section after that is clear. If a positional element was allowed then the driver would not know when one of the Yellow aspect bulbs had failed and there would be a possibility of the wrong information being imparted to the driver, which is an unacceptable risk. Signal aspect bulbs are continuously monitored and when any bulb fails the signalling system sets the signal to danger (Red). But all of this is getting a little away from the chargers' LEDs. Pete.

Exodies Posted June 26, 2014 Share #38 Posted June 26, 2014 Dearie me. Sorry for the confusion; it was someone signing themselves as "farnz" who suggested that positional data was present in railway signals. It shouldn't make any difference as long as the driver can tell a lit aspect (lamp) from an unlit one because the message is also communicated by the aspect's position on the signal. Pete.

swamiji Posted June 28, 2014 Share #40 Posted June 28, 2014 Colours are a bad signaling method for a human audience. Just think of all our friends using the colourless camera. Hmmm, A flashing white light for charging, and solid grey light for 80% and a solid black light for charged. Link to post Share on other sites More sharing options...
