@sundberg84 one of the 0.1uf caps that i use has short leads and wouldn't fit that hole spacing. They are higher voltage capacitors that i bought years ago for another project that i am trying to use up. I do see your point though.
@nca78 They have a youyue 858D and it is $92 and another for $63. The ones I am looking at are these for $30 with free shipping:
858D Hot Air Gun Rework Station SMD Solder Soldering Digital 220 /110V 700W New
Epilog: I ran the brushless spindle unloaded continuously at its maximum speed and monitored its temperature using a DS18b20 temperature sensor beneath the holding bracket (so, getting the least amount of circulated air onto it). It reached an equilibrium temperature of around 31C. Also, it turns out that it actually does have pretty good air flow. So, I’m no longer worried about this spindle getting too hot.
the modified SWR is a good idea I'll follow up on it.
The scanning of the antenna input ports will show me if there is an antenna on that port or not.
Yes I will know were the antennas are connected at any one time but the scan will allow me to know if the antenna is up or shorted and if not move the transmitter to a dummy load on boot up of the system.
all the other auto tuners I have seen just move the antenna from one input to the next with no way of knowing if there is or is not an antenna on that input and what can happen is that you may end up keying to nothing.
And could damage the finals in the amp or transmitter.
With this scan on booting can move the transmitter to a safe spot .
This tuner will be total auto . I want to be able to boot up the tuner and transmitter and have the tuner not only tune to the frequency but check and correct any antenna problems from the start.
I still will be able to turn on or move any antenna on line that I want to use and I will be able to see from the from panel just witch input I have antenna on at that time.
If you do a search on You Tube for ZT-1000 auto tuner you will get an idea of what I am building,
I will be using most of his design but coding it myself, he is not letting the code of build out to the public.
I have figure out from his video just how he has build the tuner .
I can write the code and by doing so I can change how he treats the antenna and transmitter input ports.
@donny152 You should try OpenLuup. works great with mysensors and vera plugings and is very stable and you can use your vera as a zwave controler. http://forum.micasaverde.com/index.php/board,79.0.html
@bjornhallberg said in Best CNC for milling/routing wood?:
I think the mechanical stuff is ~$1400 and then ~$600 for steppers and spindle and a few other things.
Seems like a very good price for the rigidity and such a large format, at least compared to other offerings.
@alowhum I've heard of geophones being used to detect footsteps outdoors. Cost was around $60/sensor IIRC.

@nca78 I'm still deciding what to use. Pro Mini if I don't find anything better.
I'm interested in where you buy your BME680 breakout boards, there are not so many around
I think I bought them here: http://www.watterott.com/de/BME680-Breakout
I'm located in Austria
I already had a Fluke 72 (old one with no current range below 10 Amps).
So for better accuracy, I purchased an HP 3478a digital multimeter on eBay for about $140. It gives me all the accuracy I want (but probably don't need) and has 1 µA resolution (accuracy is somewhat less but for tweaking battery usage stability makes it usable.
Of course it is not as portable as it needs mains power.
Mysensors has a "savestate" function that can be used to save variables in eeprom without too much hassle, but in your case it since it is a mains powered node you could just report every pulse and have the controller save the data and when node boots it will just asks Domoticz the last pulse count (look at energy pulse meter example in library) but I think that will work only if using mqtt gateway as for the ethernet it will just miss the retrival of the pulse count because the controller takes some time to connect to the ethernet GW. As an alternative there are other solutions like ESPEasy that have already some built in funtions easy to use without need to do lot of coding.
@wes Maybe your resistors don't have a high enough power rating for the current that's running through them? i.e. holding down the button heats them up and therefore changes their resistance? That might explain the slowness to react as expected after the button is released. After release, they cool off and eventually return within their expected resistance tolerance, at which point the expected behavior finally happens.
First attempt playing with the logo. I did a manual filament change from yellow to blue. Didn't have any black PLA, only ABS, otherwise I would have used black. This is more of a lithophane style which didn't do the best, but is still okay. I want to try to figure this out using paths in inkscape and exporting them to OpenSCAD. Having some trouble with that though. I'll figure it out in time.
The picture is next to a soda can so you can get an idea of the size.
