@Osch Kind of hard to splice small gauge wires without soldering or terminals. A step towards wire splicing without soldering is to buy a wire stripper suitable for small ~20-28 gauge wires like this:
• Small wire nuts (probably the purple ones for 20-28 gauge or so). Requires wire stripper. Just cut jumper wires in half, strip, and twist up 3 or more for more grounds. Wire nuts make excellent connections, maybe use electrical tape to wrap them if there is any concern of tugging on the wires.
• No-strip insulation-displacement connectors aren't likely to work with the tiny stranded wire in your jumpers.
• Crimp splice connectors like used for telephone wire splices might work but then you need a decent crimper, although a pliers may do. May be too big for smaller wires.
• Screw terminal blocks can work well for wiring to sensors if you have a place to anchor the block.
Well I've had some success on my own. There's another thread from January where I've discussed a little bit withe the MySensors team.
Your dirty hack is beautiful in it's simplicity! I have been roving a round in the library files and wound up in MyHWAVR.cpp to change a little bit. And I think I have found a way which is also simple. But I have to offer the change up for review to have it incorporated in a future version of MySensors. Only downside that it's tied to AVR for now. Needs testing to get it going on SAMD as well probably.
For my tests I have been using the enableInterrupt library by the way. Found no trouble using that. And I have a little RC network on my switches to suppress bounce. Checked that on a scope and that worked like a charm.
Are you sure that is the best solution? I'd go with something like an esp8266 that transfers the log on a ftp server on your network, this way you are sure data is transferred, otherwise using mysensors over wireless you could have some messages lost or if controller is down for any reason you would loose all that day log
@LastSamurai thanks. Appreciate the feedback. I am going to test it on a samd device as well and if it looks OK, I'll have the core team review and approve it. Then I'll start looking at the simplified security option.
When you are planning to buy an oscilloscope the most important thing you should consider is the output signals it produces. I remember when I was in college it was the only equipment which was antiquated and outdated. Tektronix MSO2024B is a nice option I guess. Also, Tektronix MDO4000 is the best general purpose scope that is available today. Mixed signal oscilloscopes are also used these days.
1-wire doesnt do well with star wiring, linear is better, choosing the right pull up resistor is important, (4.7k is common, but not always the best), parasitic power? If so longer conversion time. Search "reliable 1-wire", there are some good wiring guides out there. It looks like you have 5000 millis fornconversion, should be long enough. Maybe too long? I dont know how 1-wire handles holding on to the reading, maybe combined with parasitic power they are shitting down before you get the reading. In parasite mode you have to cycle them enough to keep them powered up.
How many thumbs do you require to create one switch? Is there a good thumb to wheel ratio that makes for a good switch? Would you make the switch out of different wheels, say light passenger vehicle versus a late 16th century cart wheel? Would you be able to specify the amount of each type of wheel in the production of said switch? How about thumb types? Can I have one switch made from virgin female thumbs, and would it be more expensive than one made from 50 year old retired carpenter thumbs? I would have thought the carpenter thumbs would be more expensive than virgin female thumbs, as most retired carpenters have lost part of their thumb by the time they retire, so would be quite rare to obtain.
TL:DR, your products suck, and have been blacklisted from my stock ordering options too. So long!
With respect to the industrial light sensors: Is the problem related to people not moving enough around your office? Lack of movement causes these sensor not to trigger. In that case I think the use of a PIR sensor could probably not help you a lot (although they could be more sensitive, have no real experience with these sensors).
Have you thought about using a tactile switch in the chairs in your office? If someone sits on its chair, every now and then a pulse could be send acting as and presense sensor.
@VaZso i see 0-85 channel and i see most is silent , but my controller and gateway is 1m distance with router (because controller connect with lan cable to router)
anyway thank you. i think this is related to just chinese radio...
