Search should be working again now. Sorry for the inconvenience.

Ok, added a ssi server date in the static html maintanance page.

Also purged the cloudflare cache in case something got trapped over there.

That's strange.. I cannot reproduce here and the web server does not report any errors that could explain it.

Anyone elese experiencing the error message?

I think the error has been fixed now. Thanks for notifying!

Thanks for reporting, got it back up and running again.

Do you know how the brave browser identifies itself?

This is the last 30 days browsers that has hit the site:

@NeverDie

Hehe, I think we will continue our self isolation. The good thing with IT jobs is that it allows you to work from home. Just hope the teenage kids won't drag it home from their tri-weekly school-visits.

For "young" people like me in their 40-50, it seems we'll have to wait a few months more in Sweden.

Ok, could not find the root cause for why the embedded forum thread on openhardware.io couldn't detect if user has a valid session/is logged in to the forum.

Did a workaround by adding a "Comment" button which redirect user to the thread on the forum.

@BearWithBeard
Good!

Still investigating the comment problems on openhardware.io. Might need to do manual restarts of the forum to test things later on.

Fixed the rate limit when fetching data from github (now 5000 requestst vs 60 per day). Should fix the fetch problem we saw on the main site @mfalkvidd.

No forum crashes/restart for 2 hours. Seems fixed.

Yeah, noticed that as well an hour ago. It was actually caused by an exception/crash of the forum. I think I pinpointed the problem and fixed it. Need to keep an eye on the logs over the day.

@mfalkvidd

I fixed the raspberry article, the updated markup-parser seems a bit more picky about newlines before/after headers and code-blocks for some reason.
Edit: Correction, the bare <br> html-elements all over the article needs to be separated with newlines

Hmm.. something seems to be broken (for me as well). The "Login" button should not be present if you are logged in to the forum. Clicking it seems to generate a js-error.

This all might be triggered by some new cross-site security feature of chrome and it could take some time for me to figure out a solution.

@Yveaux

You're always welcome!

Just finished the last bits of my automated pergola project I've been working on during the summer.
My Automated Pergola – 04:20
— Henrik Ekblad

The roof/screen motors is Somfy IO based so I would have to do some remote.hacking or getting a KLF 200 unit from Velux to integrate it into my NodeRed automation.

The lights is controlled by a Shelly RGBW unit.

Hi @mrhutchinsonmn,

Yes, it is possible to contribute your own tutorial by creating a project on openhardware.io (it shares the same database as mysensors.org) and submit it for review. After publishing, I can "move" it to the mysensors.org site and you can continue editing it.

For long time contributors we can offer full editor rights which means you can update any article on the site. It's a bit scary to hand out this right to anyone so you'd have to prove yourself first

If something is wrong in the current articles, you can of cause pm us the error to be corrected.

Thanks.

Yeah, PayPal are blood sucking leeches. I hope more merchants will boycot their service for other alternatives and let them die.

Hi @TRS-80,

We have no problem beeing open with the financial situation. The revenues has declined the last couple of years. Both donations and affiliate/ad vise. But I have tried lowering our monthly costs by consilidating servers and making backups of forum/openhardware.io db to my home NAS. The total cost of running things is now ~$100/month excluding domain/mailgun fees etc.

We had a short burts of donations in April this year from some germans that added up to almost $60.

The monthly google ad revenue is ~200/month so we're floating without me having to use my companys as a sponsor.

The MySensors community will not shut even if revenue goes below income (unless I go totally bankrup ).

@GertSanders, dxf should be recognized now.

I would have to add dfx to the valid list of formats for design files. I'll let you know in this thread when it has been deployed.

The page seems to work for me. Could it have been a temporary glitch?

@NeverDie
Here in Sweden many supermarkets open an hour earlier only for the elderly or people with preconditions.

Quick and Easy

• Ethanol (96%)
• Aloe vera gel
• Tea tree oil

Mix 3 parts isopropyl alcohol to 1 part aloe vera gel. Add a few drops of tea tree oil for the smell.

Advanced

• Ethanol (96%)
• Glycerol
• Hydrogen peroxide
• Distilled water

Less sticky than the previous recepie and the recommended mixture by the WHO.

Mix 2.5 dL ethanol with 30 millilitre of glycerol (keeps the alcohol from drying out your hands).
Mix in 15 millilitre of hydrogen then another 60 millilitre of distilled or boiled (then cooled) water.

These proportions will give you a spray that can be applied to hand towels for wiping of hands and surfaces. Use less water if you want a more gel-like substance.

@The-Grue
The page does not require internet to work (once it has been downloaded).

It has always been like this. In order to do like you propose, you'd have to send in a pointer for the light variable into the function to be able to update it. This would be a bit awkward and none standard for simple scalar values.

Do

lights = loadState(10);

Yes, I've noticed a small change in the font as well. We should probably switch to Roboto which is used on the other part of the site.

Forum has been upgraded and migrated to a new database. We are investigating a couple of issues.

1. Search is currently not working. Fixed
2. Article/project comments from openhardware.io / mysensors.org is not shown. Fixed

Let us know if you run into any more unknown issues.

@Fumée-Bleue
Maybe you could add an image and description to the project?

Wow, you've got an market place for plugins already. Cool! And great looking website!

@mfalkvidd, I think he doesn't have permissions to update the mysensors.org page.
UPDATE: Hmm, I now see it's owned by user2684... so I guess he CAN update it using the login on openhardware.io.

@user2684, just PM or email me new screenshots and textual changes on hek@mysensors.org and I'll update the page.

Woa, congrats on posting project #400 on openhardware.io!

@sundberg84, I will try to solve this with @kiesel over PM.

From the author:

The main reason for deleting the project is that new OpenTherm specifications are coming out with different voltages etc. and this PCB has not been tested with them. As such, someone making or purchasing the PCB may run the risk of damaging their boiler and I do not currently live somewhere where I can play around with making new circuits in line with these new protocol standards. Of course, if I ever get the opportunity to develop a new circuit and create a PCB, I would be happy to make a new project for it.

Thanks a bunch @alphaHotel, incorporated now!

@franz-unix
What keeps you from having it open source and still sell assembled boards? I truly believe 90% of the audience would buy it pre-made from you, if the price in resonable. Ordering a pcb, all components and then soldering it is quite a barrier for "ordinary" people.

You will also be able to receive bug fixed/pull requests from other community members if you keep your project on github/openhardware.io.

Here's an example for the MySensors Micro: https://github.com/mysensors/SensebenderMicro/pulls?q=is%3Apr+is%3Aclosed

Great work @alowhum!

Page added. Please get back to me for any changes/additions you'd like to to.

https://www.mysensors.org/controller/webthings

The error says "Invalid Home". Please check the home page setting a little higher up on the settings page.

@mfalkvidd, I took the liberty to move the forked discussion from "OpenHardware" to the "Hardware" category.

Yes, as long as you distribute the source code for your device.

But the Swedish tax authority wants their taxes (even for a hobby income)

Hi @kalina,

Yeah, thought about it. Would have been fun to do something like this together with the manufacturers. e.g. They offer a price of board X assembled if we reach 100/1000/10000 orders.

What stopped me was the payment fees and hassle of handling/holding peoples money during the kickstarter period. A lot could go wrong... and as a hobbyist project, I don't have the resources to make any losses when things fail (people withdrawing etc.) or handle customer support.

I've found something similar on the market though, https://www.crowdsupply.com/, maybe you could check it out.

Yes, selling boards (none commercially) is ok.

@mfalkvidd
Sorry, can't find any way of setting default options this this for the Solr forum plugin.

Sure!

henrik.ekblad@mysensors.org

.. and any updates you want to see in the text as well.

Yes, maybe we could add a more prominent link in the article to the auto generated documentation. Right now the link easily missed in the ingress.... and it does not link directly to the overview documentation here:
https://www.mysensors.org/apidocs/group__MySigninggrpPub.html

I don't think we should scrap the page entirely as it contains the none API technical parts as a good overview.

The documentation at the time of the created revision is actually included in the zip as README.md (markdown).
You should be able to view the file properly formatted in an md-editor or online using I.e.. https://dillinger.io/

Uploaded images was never included in the revision dumps unfortunately.

Hmm.. That's exceptionally strange. I haven't heard of any other project losing uploaded files.

Have you seen anything similar in any of your other projects? Sure you really published them a year back?

Eh, not that I'm aware of. What files were missing?

Thanks for reporting @dakipro. It seems to have been a caching issue in the service. Should not appear again.

Ok, revisions now available. E.g:
https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors#tabs-revisions

Zip files with old revisions get stored on openhardware.io but is not exposed in any good way for the end user today. They're only accessible for the manufacturers.

I will see if I can show it somehow. Maybe a new tab on the project page listing old revisions with download links.

@sundberg84

Could you give it another try try uploading the files. They should work now.

Yes, should be possible to allow those file extensions. I'll take a look at it tonight.

You can also press the cloud+up-arrow like icon in the composer to get a image file upload dialog.

Just drag and drop the image in the composer.

Impressive @Kokosnoot!

This thread contains comments for the article "Air Humidity Sensor - Si7021" posted on MySensors.org.

Thank you for the warming post @Soloam.

I've tried to keep the monthly costs to run the community as low as possible (~150 USD/month for hosting, domains and email services).

The paypal donations is a welcome income, but as you say it's very sporadic. The last 12 months , we received 18 donations with the total sum of $369. From what I've seen, many of them is from reoccurring donors.

The community wouldn't be able to cope with the costs solely on donations. But luckily the google ads gives ~2-300 USD/month. (even when ~50-70% of our techie user base have ad-blockers enabled, rendering us nothing).

So my suggestion is that everybody who enjoys this community makes sure to whitelist it in their ad-blocker.

And of course... I hope everyone wants to be added on the hall of-fame! (let me know if you want to use your forum handle instead of real name in the support page)
You can also choose "reoccurring payment" when doing a paypal donation if a $1-month-model suits you better.

Yeah, openhardware.io is dependent on the https://github.com/tracespace/gerber-to-svg / https://www.npmjs.com/package/pcb-stackup-core project. I use it to generate an svg which then is converted to png with alpha channel which is feed into some three.js magic hack on the frontend to "cut the holes" using alpha in the png.

Some gerbers seems to render a bit funny. I have tried tweaking it and have sent bug reports to the author a few times. But pcb-stackup is a slow progressing project. The outline have been disables due to even worse rendering in many occasions. Not sure what triggers faulty renderings. Kicad/Eagle gerbers seems to work better for some reason.

In this specific case I guess the problem is because you're using a none-standard naming of the gerber files. Check some other project on openhardware.io that renders fine to see the correct naming of the different layer-files.

@monte said in Interactive KiCAD BoM:

https://hackaday.com/2018/09/04/interactive-kicad-boms-make-hand-assembly-a-breeze/

Nice project! Might be hard to integrate on openhardware.io though, as it looks like a KiCad plugin.

@John-Oliva, nice! Added it to the MySensors collection:
https://www.thingiverse.com/mysensors/collections/mysensors

@mfalkvidd
Ok, didn't know that these two had a special thing going. Thanks.

@mfalkvidd
I think they can actually.

Maybe you should do some tests to see if it is looks resonable.

This guy:
https://pi.gate.ac.uk/posts/2014/01/25/raingauge/
have calculated it to 0.2794 mm per tip.

The gist has now been updated to the lastest running on mysensors.org

Hi @TomG,

It's current not possible to combine orders (more than changing the 10x multiple of the same board). Adding combined orders would complicate the integration quite a bit with the manufacturers. Nothing I have in the todo-backlog at the moment.
But I agree with you that the shipping cost becomes a bit high when doing two separate orders (that later manually gets combined by the manufacturer). They all got their own way of calculating shipping cost. When testing, they seems to add $2-5 when increasing quantity by 10 on a single PCB order.

You can probably add a udev rule in /etc/udev/rules.d/

Move the MySensors include below your defines...

You should also have a look at this thread on how to modify a commonly used motion detector to run off 3v3.

@NeverDie, yes, and to have a small project to learn app development.

I've been busy this week building my first native android app in (nativescript-vue). It will control my new car charging station (HALO Wallbox). The charging port will automatically turn on when I'm closing in to our house and turn off off when leaving the area.

@sundberg84

Nice, maybe add a diffuser? I've found that greaseproof paper (smörpapper in Swedish) works pretty well.

Thanks @fredswed, updated.

I did some development but it has been "on ice" for over a year. The idea was to offer something running in the "cloud" for quick testing and sharing sensor readings with friends and family. But (as always) it quickly grow out of proportion (storing historic data, dashboards, mail triggers etc) and I realised other projects does this much better. I.e. a hosted NodeRED would do the trick (e.g. https://fred.sensetecnic.com/).
Another issue would also be how to handle the hosting cost for the service (which would require a few more cpu cycles and storage than the current site).

Not sure what will happen with the code, it was pretty tied to the main site with users etc. Maybe I will pick up the work some rainy day.

Bare copper should reflect light. What about sending off ir light (with some dampening material on opposite the other side). And a shielded ir sensor next to the sender to detect the reflected light?

You could perhaps try with one of these:
https://www.ebay.com/itm/5X-IR-Infrared-Obstacle-Avoidance-Sensor-Module-Detect-Distance-for-Arduino-DIY/142649289652?hash=item21368f6bb4:g:nAQAAOSw-4RaUyOd

@rodaman said in Door, Window and Push-button Sensor:

http://www.mysensors.org/build/binary

I don't get the buttonPin array thing at all?

Why not just:
pinMode(i + FIRST_PIN, INPUT_PULLUP);

@rodaman said in Door, Window and Push-button Sensor:

What is the purpose of the buttonPin-array?

E.g.

pinMode(buttonPin[i + FIRST_PIN], INPUT_PULLUP);

This will fetch a random (probably 0-initialised) value from the array and set pinmode on that value...

I had a good laugh when examining the other board. Is this a normal solution for remote-in?

@NeverDie, well, I started my trouble shooting with a lucky google search. For old devices like this, you are often not the first person experiencing a problem.

My old Yamaha YSP-1100 soundbar just decided to die.

After some searching I found the problematic capacitor. A 22uF 600V had dropped to 6uF....

!

Thanks!

Had to disable board outline mask as it sometimes messed up the rendering. Managed to extract dimension (and hopefully number of layers) from the gerbers which gets filled into the form.

I've created a new service for comparing prices on PCBs and assembly.
https://www.openhardware.io/quote

It's still in beta phase and more manufacturers will be added as soon as I can figure out how to quote their online systems.

You can also use this page to do fancy 3D renderings of your board. Just drop a zip with gerbers in the Upload box.

Open for feedback and improvement ideas.

P.S. The historic price graphs will build up over time. It will be empty until we've had at least one query for the same specification earlier.

I can see the email address used when registering here. It'll arrive in just a sec.

@dbemowsk

I can send you the svg via mail if that is ok?

@ricorico94

From the NRF24 datasheet:

https://www.sparkfun.com/datasheets/Components/SMD/nRF24L01Pluss_Preliminary_Product_Specification_v1_0.pdf

So, you should probably choose address a bit careful.

To change base address just add a define in your sketch like this (before including MySensors.h):

#define MY_RF24_BASE_RADIO_ID 0x00,0xFC,0xE1,0xA8,0xA8

@ricorico94

Besides channel, you can also change the MY_RF24_BASE_RADIO_ID for nrf24. This will give you the possibility of a huge number of networks on the same frequency if the traffic is low.

https://github.com/mysensors/MySensors/blob/development/MyConfig.h#L418

Nice, any links/pictures?

@wes
If you create a project/page on openhardware.io about the temp sensors, we can embed it on mysensors.org.

16 versions! Impressive iterative work to get the perfect result.

You could also try moving the node further away (5-10 m) from the gateway.

Thanks, updated.
