💬 In Wall AC/DC Pcb for MySensors

[sundberg84]

@carthique - You need a 110 v varistor maybe something like: http://www.ebay.com/itm/321024816822?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT&rmvSB=true. Fuses and other components is the same.

@sundberg84, when I go to the order form, the revision there is M.Rev3. Which version of PCB does that manufacturer revision correspond to - 3.1 or 4.1???

[sundberg84]

@ashway - this is correct/latest version. The manufacturer rev 3 equals the latest 4.1.

Excuse the possibly silly question but the buy options is PCBs only? Or does it come with the housing too?

[sundberg84]

@shabba - PCB only.
I recommend using 3dhubs.com and find a local 3d printer for the case.
Files (.stl) attached in the project.

[shabba]

@sundberg84 thanks - I had a look in the design files and I think I covered the comments but could not find a .stl file.

[sundberg84]

@shabba - sorry you are right.
If i remember right I removed it because I wasnt 100% sure it would be ok going from 4.0 to 4.1 on the pcb.
Let me have a look and post it asap.

Hi sundberg84,
I bought 10 of these PCBs. So can I use this PCB, add a relay and fuse and use it inside the wall to control light switches? or should I go rather go for the other PCB "In Wall AC/DC Pcb (with Relay) for MySensors (SMD)" ?

Thanks
Bob

[sundberg84]

@bmokena - if it fits, that should be ok. This PCB is made a more generic pcb so you can add any sensor/accuator to it including a relay. Use the MysX i/o and you can controll your relay through D3 for example.

Hi, do you have any local Swedish printing services to recommend?

Ps. Got the PCBs from Pcbway yesterday and man was I surprised how small they were. Looks great and hope to get some nodes up and running soon, once all components get here.

[sundberg84]

@johmei - sorry, I wish i had any good recommendations for local PCB service.
The only research I have done leads me to that they are VERY expensive compared to these 10x10 chinese.
Good luck with your build! Images are always appreciated! ;)

[johmei]

@sundberg84 - Thanks, but I was thinking about 3D printing services for boxes, cases and mounts in very small series (maybe even singles)?!

Regarding images we'll see if I manage to get any AC stuff going anytime soon. I have a lot of respect for AC and probably want to get to know the Arduino platform a bit more first. Got my first couple of regular DC nodes running yesterday and they have been running really well for 12 hours now (impressed of the small nrf24+ radio range). So many ideas to explore. =)
Actually ordered a set of your newbie PCBs a few days after my In wall AC PCB order so there will be a lot your autograph around my house..

[sundberg84]

@johmei - haha, I hope they will help you some in your quest for HA. About 3d printing I use 3dhubs.com and have tried different once and been satisfied. Go for one at your location if you want to pick up. I use one in Kalmar with shipping I can recommend.

[johmei]

Can't help myself but have to see if I can get a AC node going. question regarding capacitors: C1 is specified as 10uF in the circuit diagram but the BOM states 0,1, 1,0, 4,7 uF capacitors. What is the recommendation from the creator? Thanks

[sundberg84]

@johmei - you are right and the BOM is updated.
C1 should be a 10uF in my schematics, but its optional. Its recommended to have one higher and one 0.1uF capacitor with the voltage regulator since they can help avoiding spikes and drops.

[smilvert]

@sundberg84 Which housing are you using to this project? Can't find the stl-file. Does the 3dBoxWRelay.stl from the smd-project work here as well?

[sundberg84]

@smilvert - No, Im not sure.
I have not made a 3d box to the new version - let me have a look at that. Im working all weekend but i will look into it asap.

[johmei]

Looking at the images and schematics(V4.1) it looks like the 18B20 and LE33 are soldered in the wrong way?! old images or am I looking at this wrong?
Still waiting for slow blow fuses so not ready to test yet.

[sundberg84]

@johmei - some parts was supposed to be soldered from the bottom side, so it depends :)
Keep it in mind when you are building. I might have to make this more clear somehow on the PCB as well.

[johmei]

Ok, I was reffering to the pictures of the assembled board. My half done Node (no AC) works well with the two components "the other way". confised Traced the PCB connections before testing with 5VDC. =) As long as everyone double checks what they are doing it is no problem.
