What did you build today (Pictures) ?

@petewill said in What did you build today (Pictures) ?:
Question for you all... what are you doing (if anything) to vent the fumes from soldering? I haven't really been worried about it in the past but it makes me nervous with my son doing it with me.
I have a Hakko 493 clone, it has a carbon filter to absorb the smoke (or most of it) so it doesn't smell too much in the room when I need to solder for a long time and I can't open the windows. I don't have a link because I bought it in my local shop (it was cheaper than AliExpress + shipping), but you can easily find similar models or clones of the FA400 by searching "smoke absorber" on AliExpress.

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....
! -
Today I made and assembled a board which instantiates the schematic I posted above two days ago on this thread:
Basically, it sends a wireless signal as soon as the CNC machine finishes its work. -
@neverdie could you achieve something similar with a sonoff pow measuring the whole cnc power consumption?
-
It's a very good suggestion. If I wasn't already done, I'd try it. If it works, the Sonoff would be simpler and less effort.

Another hour on my... whatever it is.
Anyone that can recommend a open source router (hardware) or cheap hardware for pfsense which isn't that big and draws that watt amount.

@gohan it's a pc with my intention to run pfsense (open source router) but it is old and draws to much power for my taste.
-
How much power does that pc draw?
Mine:
Asrock Q1900B-ITX + pico 12V to atx psu + PCIE Intel Nic 2/4 Gbit ports + SSD can run on 20W or less, but I believe the J1900 Celeron lacks AES for VPN if you care about it.HP DL 380 G7 2xL5640 hex core, 144GB Ram, 4xGbit Nics, SSD, 90W at idle (99.9% of time) and pfsense is only one of the VMs I constantly run, besides OH2, Ubiquity controller, Nextcloud. The ability to snapshot a development VM, or fork (clone) it is a killer feature for me.
Another DL 380 G7 in standby is drawing 15W.
Phu*ck I have some old shitty switches that draw 30-40W, not to mention security cameras, 300-500Wh during the night for all my crazy home automation&security.

@sundberg84 not cheap but 15W (at max load): https://www.aliexpress.com/item/Pfsense-Hardware-Qotom-Barebone-Mini-PC-Nano-itx-Core-i7-4500U-Fanless-Mini-Computer-X86-Router/32799048185.html

https://www.netgate.com/solutions/pfsense/sg-1000.html 2.5W idle -
the little netgate looks cute, but wondering if it would be enough powerful (for streaming etc.)
@sundberg84
when you already have parts laying around, like ram, hdd etc, you could also use intel J3355 or J4205 cpus, maybe better than J1800. J3355 boards are not expensive. Then add a pcie NICs or a simple usb to gigabit..
I would choose micro atx board because often cheaper, same for ram (more compatible ref vs itx boards sometimes are restrictive), and it may be more flexible for pcie slot. That is, if size is not a concern.Or maybe a more powerful cpu, if you plan to factorize lot of things in VMs etc.
In both case it could also allow you to save power by decreasing number of rpis for example. But an interesting math would be pros&cons between features, power consumption saving, cost of a more expensive setup vs years for ROI about power savings (if that is the point)
Maybe we'll see new mini pc router in future with new sbc and mcus..

@sundberg84 you could have all the rpi's running on the pc hardware, and save a couple of pennies on the electricity bill..
I exchanged my HA rpi with an atom based machine, as it had 4Gb ram. Now I'm using docker to containerize the different parts of my setup (influxdb, grafana, domoticz, nodered, moquitto, etc.). Ok, it uses a bit more power, but not that much compared to the flexibility that I have now. So now I have a lot of "machines" for handling the different parts.. I can even spin up an experimental domoticz in seconds (I'm playing with mqtt for backbone in my HA setup, instead of mysensors serial protocol, and a lot of http calls to different parts of my system.
