Hello thanks for the advice you can pass the project to order the PCB

Hello thanks for the advice you can pass the project to order the PCB

Here you have download link for the PCB files - https://drive.google.com/open?id=17fn7bGRfCZOl3Ork7gRJEK2GKQiRCXMd
This latest revision i have not tried myself, but i only swapped the Wemos D1-mini model to a new one, since the old one did not work with printing on the PCB. This new one should.
The pictures showing the board in the sub folder not updated with latest model but it doesn't matter. Also BOM is still the same.

bigdaddyale ordered boards with these latest revision i think, so he will probably be the first trying them.

I used the original files w/o the correction.

Here is the image of the new silkscreen Version 1.11

 

[Bigdaddyale]

Version 1.1 The pads and drill holes are there under the white bar just not visible in this image

 

[RollE2k]

Damn i see that the text is alot "wider" when pulling the prints than when editing in eagle.. the "compact" output terminals does not have text straight above each pad (GD A3 A2 A1 A0 GD). Shouldn't be any trouble for most people i guess!

 

[pbezza]

I received my v1.1 boards same day as Bigdaddyale. Still waiting on many electronic parts before I can put it together. Have spare PCBs if anyone in Australia wants one.

 

[toadyus]

My boards turned out nice and the d1 mini sits nicely. If RollE2k is ok with it I might be interested in building people boards if they want a fully populated one.

 

[toadyus]

Surface mounted. It's the only part that is surface mounted on the whole board. For cooling purpose, and I think most people can solder such a chip even if you are not used to smd soldering.

I tried make the board as much through hole as possible, so everybody can solder this themselves. If I did it only for myself, smd would have been good.
And for those not used to smd soldering, just tin the large pad first, then put the regulator there with tweezers, while still keeping the pad hot.

Is this the correct part for the voltage regulator?

I have tried importing recipes from Beersmith but no information gets displayed. I renamed the recipe to .xml but the recipe still wouldn't import.

I imported recipes that I downloaded from https://www.brewersfriend.com/homebrew-recipes/ and they work perfectly.

Has the beersmith beerxml format changed? The 2 files are formatted very differently.

 

[pocketmon]

"BSMX" is proprietary format of BeerSmith. BeerSmith does support BeerXML, and you have to choose the option when exporting.

[QUOTE = "RollE2k, post: 8509633, membro: 234389"] Qui hai un link per il download dei file PCB - https://drive.google.com/open?id=17fn7bGRfCZOl3Ork7gRJEK2GKQiRCXMd
Quest'ultima revisione non ho provato da sola, ma ho solo sostituito il modello Wemos D1-mini con uno nuovo, dato che quello vecchio non funzionava con la stampa sul PCB. Questo nuovo dovrebbe.
Le immagini che mostrano la scheda nella sottocartella non sono aggiornate con l'ultimo modello, ma non importa. Anche BOM è sempre lo stesso.

bigdaddyale ha ordinato schede con questa ultima revisione, penso, quindi sarà probabilmente il primo a provarle. [/ QUOTE]
thanks for linking them

That is no problem for me, I have no commercial interest in this project.

That regulator should work fine, yes. But if people are running 5v input, regulator is not needed.

Oh, okay. I don't see an option to download as any other format. I am downloading the recipes from https://beersmithrecipes.com/ as I don't have a license for the BeerSmith3 program.

 

[Bigdaddyale]

RollE2k, can you break down the parts needed for BrewManiacEX and for BrewPiLess? A lot of the guys are receiving their boards and I'm sure there are going to be questions.

 

[Bigdaddyale]

That regulator should work fine, yes. But if people are running 5v input, regulator is not needed.

Why would you not run 5v? to protect the esp8266 running BrewPiLess?

 

[RollE2k]

Why would you not run 5v? to protect the esp8266 running BrewPiLess?

Because you may run 12v relays, or other 12v hardware in the same box, which means you can still use same PSU for the board, as the other stuff. Also most PSUs are quite noisy, so filtering the PSU to the board does not hurt.

Regarding components:
if you have 5v input, you can hard-wire D4 and "REG-BYP" Also JP1 can be hard-wired to either 12v or 5v in that case, since the 12V option is really "input voltage", while the 5v option is 5v from secondary of the regulator.
If running 12v then put a diode in D4 and wire JP1 depending on if you use 12v or 5v buzzer.
I should also say D4 is for protection, so if running 5v psu with trimmer, i would perfer to keep D4 and increase voltage to approx 5.7v instead. You can also skip a few of the input caps (C3/C1) if you run 5v input, but they do no harm there, you get a bit better filtered voltage.

If not using "piggyback LCD" (but external LCD) then you can skip IC3, Q5 , TR1 and pins for the LCD.

Then what components you need depends on what outputs you are using.. Say you are not using SHTR/ACT(which is sparge heater in brewmaniac), then you can skip D3, Q4, R12, R11, R15, and the terminals for those outputs. You can do same for all outputs you don't use, it's quite easy to see what resistors/diode/transistor is used for each output if you just look at the board.
Since BrewPiLess is possibly to configure different things to different outputs, and some people use only cooler, while others also use heater it is impossible for me to say what components are used to what configuration.

BrewManiacEx with full functionality and piggyback LCD is pretty much all components, except LCD-I2C output pins, and possibly 5v regulator and diode mentioned above, if running 5v input voltage.

 

[RollE2k]

Since i got a question regarding powersupply input in PM i take it here... to clarify it even more.

*If you have 5V power supply then: Jumper "REG-BYP" and D4 (you can use D4 if you can increse power supply to 5.7v), Don't install regulator, and possibly skip some of the input caps.

*If you have ~9-12v PSU then: Install D4, Regulator and input caps. Also DO NOT jumper REG-BYP, doing so will fry your Wemos.

Chinese new year is delaying some of my components. Very annoying.

 

[RollE2k]

Chinese new year is delaying some of my components. Very annoying.

I usually buy almost all my components from Mouser electronics, because they have pretty much everything, and they are super fast if they have it in stock. The problem is that you have to order for at least 50eur to get free postage. But that free postage is FedEx so it is fast. They also take Swedish import taxes directly at checkout, so I don't get any customs fees, and it doesn't get stuck in customs either.

 

[pbezza]

I would have sourced the LCD I/O expander from RS Components Australia but they didn't have the correct IC. Found a couple of other companies that stocked them but the postage was rediculous. Ended up ordering through Aliexpress. I tried to cancel the order because they were and still are taking so long to process the order but they said to be patient and wait until after Chinese New Year and denied my cancellation request. Atleast I can still make beer with my current setup.

 

[mojonojo]

Ok this is going to sound crazy but is there anyway that a BPL instance running on sonoff can control another sonoff (whether running BPL or tasmota)? - im starting to build a glycol setup for multiple fermentors and want to control a solenoid (cold side) with one sonoff and a silicone heater (hot side) with another the idea is to pair the sonoffs (th16&basic) per fermentor?

 

[zipfly]

RollE2k have you got a complete list of parts needed for your pcb please. Have ordered pcb and just need to get parts sorted.

Good Morning.
I have a question and would like everyone's help.

I am trying to build my system in the HERMS method and would like to use more than one pump.
In the HERMS method you use a pump to recirculate water in the HLT pan, one in the MLT that is also used for BK and another pump in the chiller.

Could someone help me by telling me where I can modify the program to use more than one pump?

Thank you very much in advance

Samuel

BMex is designed for E-BIAB. You can sure use it whatever you want, but there are some fundamental design concept that might hinder it.

I had thought of supporting a second agitation deceive, like a stirrer.
The design of user interface, display and button operations, stop me.
There are only four buttons available, so combined keys is inevitable, which complicates the whole thing. I don’ even remember all the key combinations currently available . BTW, I preferred UP+ Pump to toggle the second agitation device.

I do write better C language than English. It is simpler for me to code instead of to explain. Should you have patient, I might finish the function some time later.

 

[toadyus]

I created a new pcb design that should work for both Brewmaniac and BrewPiLess. I'll hopefully get it tested tonight. I went with 12v input but I'm thinking I'll remove this as I can run this easier with just 5v.

 

[gonzalito]

Is´nt it better to use modules instead of making a fully integrated pcb? ALso you´d have less soldering.

At least that's how I made my newest brewmaniac. Pcb only holds sockets and a darlington array. Then everything goes out to different modules.. Also avoided using relays. I think it gave me EM interference.

 

[programinjo]

Hi,

I think I found problem

Version of PCB is 1.11 (BrewController(final).sch)
R14 - 470K is on the scheme, but on PCB is 1K
R10 - 1K is on the scheme, but on PCB-u is 470K

What is right?


Does anybody have issue with turning on or off heater?

When wemos D1 mini is connected to PCB and heater is ON there is no voltage on D7 and GND pin.

Wemos D1 disconnected from PCB and connected only using USB,
when I turn on heater I can measure voltage between D7 and GND pin.

 

[RollE2k]

I think only the silkscreen of the resistor marking is moved wrong on the board. The lower resistor is connected to GND, and it should be 470K as said on the board. The upper should be 1K. I have only picture above to go after right now, but that should be correct. Let me known if it doesn't work.

 

[RollE2k]

I have double checked the files in eagle, and correct - i have moved the resistor markings the wrong way.. so just go after the value printed on the board - R14 is lower and should be 470K, R10 is the upper one and should be 1K.

 

[programinjo]

Hi,

RollE2k thank you for the information.
Again, I soldered to the PCB, R14 is 470K and R10 is 1K.
I ordered new wemos D1 because the current one no longer works. He may have been faulty. I'll report later when wemosi D1 comes.
