Hi,

I don't know the second one, but for sure the first one is widely used by hobbyists.

I have this and i'm satisfied.
Construction of air ducts is not the best, but for this price...

On some italian forum it's possible to find some modification for use it all day every days, but if you use it 3-4 hours a week like me, you not need to mod anything.

Temperature tune is good and is reached very fast.
With a 0,5mm solder tip you need a little more high temperature, 440-460C.

SuperCool!!

I have business trip to China in the middle of May, so I can take the PCBs directly from dirtypcbs!

Many Thanks for your work!!

I check on the website and shipping to Shanghai will take on 2 days.

So 6days of preparation+2 days is good.

Thanks

Hi all,

at the beginning of May i will travel to Shanghai for a business trip, and I really want to take this opportunity for buy MySensors components.

Can You help me to make a list?

PCB:
what is essential to order from mydirtypcbs (i can collect it at Shanghai office)?
I funded MySensors 110-230V powered: http://dirtypcbs.com/view.php?share=11495&accesskey=9a4200ea5d04f2725b5bf0a93925ed8c

Components (i will made a complete e detailed lists):

• Arduino nano and mini + Uno
• PIR, temperature, light, humidity, etc. sensors

Other particular things?

Many Thanks

The house at the moment is completely without the electrical system, so for me the price, at the end, will be the same of a traditional system.
Also today i decided to not use a drywall with electrical pipes inside, but to use external electrical system like this just for idea:

So all is more easy (installation, maintenance and price).

I think to never resell this house in future, but if this will happen i can convert it to a traditional system in a relatively easy way.

It's true that is more simple and secure to use a commercial system, but in this way i will loose the taste to realize the whole system

@TRS-80 : In Italy we have 220V mono-phase for civil installation and 380V tri-phase for civil/industrial installation (usually for industrial machine or for a farm like mine).
And wire size usally are 1,5mm for lights (10A) and 2,5mm for sockets (16A).

Many thanks!

So the best solution is 12V for arduinos and for other thinghs the 220V line, or 12V line for arduinos with 24V line for lightings with one power supply for every floor and 220V line for outlet, correct?

Thanks

Hi,

many thanks for all your replies and sorry for my english!

I think that one ethernet cable for every switch is too much voluminous because the house have three floor of 90mq/968sqft, and with only 15 switchs/floor i will have 45 ethernet cables.

After all your suggestions and internet search i think to start with four corrugated (diameter 25mm/1inch) from the main box at ground floor for every floor:

• one for 5V (arduinos and USBs in the outlet)
• one for 12V light lines with common ground (big size cable for the ground from central box to a little box at every floor)
• one for 220 V outlet
• one for ethernet cables (centralized wifi)

As power supplies i plan to use two like that one (one for 5V and one for 12V), that not have fan and have protection for short circuit, overload, overtemperature, etc

3D print some of this DIN clip for the lights PCB relay:

And light lamps somethings like that:

For the WiFi AP a used Cisco POE Switch 10/100.

For the law is possible to run the DC line in a separate corrugated, and also i want to cover the actual brick walls with a low profile drywall on all perimeters with insulation, and electrical/ethernet corrugated inside.

I try to find the max length that i can use for 12V and 5V cables without loosing too much V and in future for sure i want to install solar panels.

It's good?

Thanks!

Hi,

my name is Bruno and i write from Italy.

I'm in process to renovate an old three floors farm house that currently not have electrical system.

From your experience is more best to have a main electrical box at ground floor for example, and from here starts directly with the lights lines, power line and with the 12V lines (arduino power source) for every floor with some PBCs relays inside, or to have one electrical box on every floor with the same lines?

it's a stupid idea think to have only 12V/5V lines inside the wall switch for power the arduino+wifi or to not have completely the wall switch?

Many thanks for every suggestions.
