What's the rough total build cost for one of these things fellas?

Hi Guys,

I've got about 20 kits available from the last order which will be my last. I've also managed to source the buttons and power sockets and 2 pin and 3 pin connectors, which should save you about $35 compared to getting them from Jaycar. Total build cost is around $160 or so if you get those parts from me. I think last time I did the sums it was about $200 for a controller by the time you add it all up.

Quick math - $80 for kit and arduino delivered, $25 for switch buttons and power sockets from me (delivery with the others), 20 for case, 8 for heatsink, power supply and ssr from ebay for 15 or so plus miscellaneous like heat compound, wiring connectors. so looks like 150/160 is about right.

PM me if you want a kit and I'll send instructions.

For anyone who is looking to get one of these kits - I've sourced the buttons, 2 pin and 3 pin connectors, and power sockets for about half what you can get them at Jaycar ($25 vs about 50/60). I've attached an image for anyone who gets a PM and wonders which parts I am talking about. You can choose between red and green buttons or swap them out for black. Red and green match the led's for heat and pump respectively.

sweet. So 75 for the kit and bits without the arduino?

Hey lael any chance/benifit of supplying the buttons and sockets etc seperate to those who have purchased off you previously

Of course! Its not exclusive, but better value as I can put it in the same package. The aim is to make as many people get a kit as want one. The pieces are a little bulky, so shipping might not make it as good value by itself. I'll need to put them in a package so 10express post is best. I think the buttons are 5ea, the sockets are 6ea, the connectors are 3/4ea at jaycar. total about fifty. I can ship them for about 35... So not that different. Unless you are getting multiples or with a shield kit.

 

[lael]

I'm still trying to find good plugs for the pump and heating element to match the sockets. The ones from jaycar are 7ea from memory.

Yeah, 80 as I need to add 5 for postage that was in the arduino price. But postage is only once for the multiple kits. I can fit about 4 kits in one express post bag I think.

How far off are you to sending them out? I'm keen as for a whole kit (the weather is crap here in adelaide, need something to do other than drinking beer ).

 

[lael]

Hi eresh,

I have the kits ready to go. So it's just getting time to go to the post office. The last month I've been away on holidays so some people's have been delayed, but I should be able to send this week pretty easily if you send money through. Cold weather is definitely good brewing weather!

Anyone got a picture of what is included in the kits and maybe one of the finished product?

I've got some bits including an arduino clone lying round at home want to see if i can make it work.

Just transferred the money lael. Buy now and worry later people. Lael has put everything together for you in these kits at a great price you couldn't match without a lot of research and time. Could be your last chance to get one. I just bought three. The new firmware from the open ardbir flashes right onto these and gives you heaps more options and settings. Not to mention counters between steps and snappier button response. There is a tonne of advice on here to build a braumeiser and troubleshoot. You will be kicking yourself if you miss out. Not affiliated etc. Regards dave

 

[lael]

Just an update - I've sent out kits for people who sent me money last week (excepting djar - holding them for when you're ready). I've got 15 kits left. I've got two kits with buttons etc ready to go, and waiting on some parts to arrive for the other 13. This is the last batch I'm doing, so if you want a kit, get one while they are going. You can certainly get all the parts yourself - but as Dave has pointed out - it is cheaper to get them when one person does a bulk order.

(not going to lie... I'm going to be glad to not to be thinking about it / have the parts lying around any more... )

I've had a number of people asking about where to get the temp probe - so I've updated the list and made sure everything is linking to updated / working links.

Thanks Lael I got the kit delivered with everything intact, soldering iron is out of the shed ready to go

If I want to run a 3600W element do I only need to swap out the SSR for a larger unit and obviously the plug on the unit, everything else as is? I'm concerned with mash strike temp and boil times but if 2400W is suitable for others perhaps I should just run with that. Also given the instructions are written for 10amp load so following them is one less thing to cock up.

Regards,

Nate

Hi Nate,

Glad it all arrived safely. yep - pretty much. The SSR is run by the arduino side, and the other side connected to the AC current. What batch size are you doing? 20L will be fine with 10Amp, Double batches need more. I use an over the side element for mine.

 

[eresh666]

20-25L batches are more than enough for myself. I dont have a 15amp spare in the garage and the power board is from the early 80's so I will give the 2400w element a go

Everything is soldered onto the board. I get power to the LCD however blank screen (theres a few joins that look rather amateurish which I will redo later today and see how it goes).

thanks for the help.
