Looks really nice!!
March 809 DC pumps use 1A or 0.55A depending on if it is 12 or 24V.Curious if anyone knows the max current requirement for the DC pumps typically used in brewing? I think the solar / tan pumps are about 2A @ 24 VDC. What about the TopsFlo?
Also, can the TopsFlo accept a PWM input or does its own controller cause PWM inputs to choke?
speaking of the newer td5, does anyone know where I can buy replacement pwm boards for these? one of the ones I bought from brewpi last year failed and they are not responding to my emails inquiring to purchase another. I send 2 the first over a week ago.TopsFlo TD5 2 wire version (older model) is 2A @ 24VDC. Newer versions of this pump have 3 wires, the blue wire being the PWM input wire.

Those are the mppt power regulators designed to buck or boost power to the pump depending on varying power from the solar panel they were designed to run off of. The black plastic topsflo pumps some use had the same chip. the brew pi topsflow pump I have is supposedly the first one topsflo designed for brewing.March 809 DC pumps use 1A or 0.55A depending on if it is 12 or 24V.
There is a version of the topsflo with PWM input, but other versions cannot be controlled remotely due to the internal micro that regulates speed. Those versions have a lame 10 position rotary encoder for the 5 speed settings it supports.

Try a VNC program. I use tightVNC. Unlike RDP you can connect from multiple PCs simultaneously. It also doesn't lock out the local display when a remote connection is present.what are the options for viewing the complete workspace at multiple locations? I find that I am pulling my hair out having to re-RDP in from three different places in the shop while the system is running...
Yes, we're hearing more requests for multi-screen support. I don't know of any way to do it with RDP, but perhaps there is another screen sharing system like TiemViewer that does it.
That said, this will come natively once we roll out the browser front end. We should have 1.1 out shortly (will be issuing the RC in the next day or so) then will begin work on the web browser capability.

Thanks. I hadn't even considered using the old panel and hardware. But there is no reason I couldn't. I'll have to ponder that.I suppose you could use the pressure sensors to calculate a rate of change over time. Not sure how accurate they would be. I personally use these to create an "electronic autosparge". The bigger question is... how will you control the flow? Measuring it is one thing, but makeing control changes is another. I personally use a proportional valve, which allows for fine tuning of the amount of flow entering or leaving the vessel. You could also control pump speed if DC, or cycle the pump(s) on and off to change flow rates, too. I do have a flow sensor (the adafruit one) and while it may not be accurate, it is repeatable. You can calibrate it that way.
Looks like I jumped ahead and now I'm too lazy to go back and edit... so yes, you need some way to control the flow.
With respect to not using the old panel... why not just repurpose your existing hardware. Simply replace the dedicated PID with the output on the MEGA... good to go!

But having two separate panels for the high and low voltage stuff with two MEGAs would be okay?
I am trying to get the network feature up and working. I have got to the MAC Address on the Termite Interface. I cannot find a MAC Address on the RobitDyn Mega with on board W5500 Ethernet. I generated one and when I enter it, it says "Mac Invalid" I tried a couple of different ones. Any suggestions?View attachment 611348

Correct me if I'm wrong, but you do need to keep sensors and outputs on the same device if you want to use feedback control elements due to the fact that the PID and histeresis control is implemented in FW. For example if you are going to use the PID element for your heating elements then you need to have you temp sensors connectected to the same micro controller. If they are connected to different devices then the only way to tie them together is with a script as far as I know.You can put everything in one panel, or two... your preference. Keep in mind its best, whether in one panel or two to keep high and low voltage devices as separate as possible to reduce EMI.

What's the preferred method to interconnect two separate panels?This is correct @crane. Sorry I was loose with the comment - I was thinking high voltage in one and low in another, but some interconnection between the two will always be needed.
I ran into the same issue make sure you use capital letters and try a few. Such as A1:B2:C3 ect.I am trying to get the network feature up and working.

anyone else updating the BC download page multiple times a day waiting for 1.1?
