I think the picture may be a piss take. :
Read the first 3 posts again then look at the pic.
Theres no way a popper is going to be the heat source for a corretto.

maheel please confirm.

I am with Thundergod on this one If I am wrong all I can say is you have a DEATH WISH..

Re: Mega Popper

sorry team TG is right, it was just a mock up i was fooling around with a while ago........ it was never even turned "on" it does sort of look like i could have with the wires running down the back ......

I agree 240 should not be fooled with and this would be very dangerous and illegal even (?)

i would not run anything like that, i pulled the popper apart as the plastic had a very weird smell (like some one had put cardamon spice in it and run it?) its in the "parts cupboard" in case i am looking for spares or something

please do not try something like that at home, sorry for taking the thread OT

that said a breville crazy popper fits very well on top of the BM here is a much safer idea......


whats that lurking in the background.......... the beginings of a KKTO?

Re: Mega Popper

to take it back on topic i reckon that if you have tried popper roasting and are considering "upgrading" you should either
1. build a cheap Corretto
2. build a KKTO (maybe a few $$$ more than a BM maybe not?)
3. buy  a gene cafe
4. buy  a hottop
5  buy  a Behmor

i have tried popper and could not get any real control on the heat. option 2 & 3 give you good / great control for possible cheap entry $$$

when Andy lets us know they are "in stock" i reckon option 5 might be very popular for new roasters......

Re: Mega Popper

The reason I wanted to go down this path was that I wanted to DIY a roaster, so buying any of the last three options is not what I am looking for.

The popper I currently have has been modded to have accurate temperature control and fan speed control, so is absolutely able to achieve any roast profile I want, its just a little too small.

The other driving force behind this project is that at the end I wanted to build an attractive stand alone roaster that can be just plugged in and used. I dont want to assemble a whole bunch of bits and pieces help together with sticky tape and cable ties which is what most correttos end up looking like.

Not too sure what a KKTO is, Ill have to do a search on that one.

My biggest concern with this project is if you assemble some kind of DIY heating element, how do you work out how much power to send to it?

I agree with the Corretto being a bit "cobbled together" looking. I am using one now. Reason i suggest is entry cost is low if you can scavenge the parts.

KKTO is very close to a stand alone roaster going to the 800gram+ roast level (i think), only extra is a cooler but any home made roaster kind of needs one IMO. KK has just about sorted his KIT for a "buy it nearly built", but still can be built DYI without major work.

I guess part of my thoughts are how much do you spend on personal development before you buy a gene, hottop etc or bigger?

controlling your heat is the big thing, scratch building with elements and fans is going to need some better understanding of electronics (triac controllers / PIDS etc?) and of course thermodynamics to some degree. I am not sure a popper style element will work and you might want to switch to a solid "oven" style element so you can get some thermal mass in it for temp control.

but i am rambling with my ideas now, keep us posted on your ideas and any trials

If its only a little too small, why not double up on your current arrangement? That would give you 300g capacity. Probably not ideal but still very cost effective and with judicious attention paid to mounting them, etc you could still end up with quite a tidy setup.... 8-)

Re: Mega Popper

Why do threads of this nature always turn into a p*ssing contest?

Dont think this is the case at all Jon.... :-?

Just qualified people ensuring that unknowing, unqualified people dont try to replicate what theyve seen. Posters have to be very careful of what they include, as without suitable addendum or comments, there is no indication that this wasnt a working contraption. Pays to be very careful.... 8-)

Maybe.

I expect that the life of the popper would be super short... a lot of heat is going the wrong way and things like the fan might last for minutes I would guess... unless it just bursts into flames.

I disagree Mal, what I see are a few guys who may or may not have the appropriate qualifications trying to prove they know best.
As far as Im concerned all posts discussing hands on 240 volt electrical work should be banned.
A coffee forum is not the appropriate place to seek or offer advice on DIY home electrical work, dont think I need to elaborate.

In principle... Maybe...  Some never read stickies and many play at home or on another forum and can not wait to post their "achivements"and or "problems".

Besides ...  240V is not the issue...  The voltage that are covered by law, are alot lower than that..  And include DC voltages.

Further more... If the unit is not powered on... The law alows any one to play...  The issue here is that prior to connecting.. It must first be deamed safe an tagged by a Licenced person with teh correct certification for the testing required.

Thus when I see people providing advice as to wiring etc my usual responce is a warning and advice to get a qualified person to do the work / check.

Even so nubes, often read one post and never scroll up or down...  Thus I also diss like it when people miss quote or copy only parts and thus ealsy taken out of context; by others...  But a great way to push ya own perceptions...

IIf we were to actually follow the Legistation and the national laws on this...

NO user ( unless qualified and with a saftey observer) would even be allowed to take a lid or side panal off, with the unit running...  That would be defined under teh act as "working LIVE".

In addition, even if the unit was powered off, and an anti-vac valve replaced (non electrical) the law sitll requies the system to be checked; before powering back up....  Wires can be knocked / uncovered or bumped and cause a un safe stiuation...

I gould go on and on...  But I think ya get my drift..

1: In effect NO user should make changes/ service / renove a panel on any equipment; unless they are qualified to perform all the required testing.... (OH... The act also required a document to identify the risks and what you found, after maqking any mods)

Thus lets shut down just about every topic and post wehere access to parts internally may be required...

From my i-brick.. Speelings included.

[edit]In addition most roaster posts and all the bread maker ones would be suspect...  One reason I have supported the KKTO...  All ELV and thus safe to build at home...

Even GWs  gauge could be a No NO as people have to open up and adjust internals..  Off or on, it breaches the containment requirements, thus the system is required to be re tested, or the work done under the requirements for working live...

Even Mal, regardless of his quals and experience.... Is not allowed to perform some things; unless it is part of his role as defined by his employment conditions etc....

For me, I am a Qualified Contractor and hold restricted tickets... But I can not install or run wiring... Only repairs that are covered by level 1 restrictions and to Tag and test...[/edit]

Reckon youve pretty well covered it AM, if ya aint qualified dont mess with it.
Im sure your not suggesting Coffee Snobs condone or turn a blind eye to illegal electrical work

Re: Mega Popper

Thats all well and good but very few post in this thread are even relevant to my questions. One of the most frustrating things about this site is that there are a few very vocal members whos standard response to any roasting questions is "get a corretto" no offence to anyone who has posted on this thread, but I have read this response a million times on this forum. while this may be the flavour of the month at the moment with out anyone trying something different how are we to ever know what other options may be out there?
I have a fairly simple idea, and I decided to post it here to see if someone had any insight into weather it would work or not. So far I have had very few posts that even address the design.

One last thing - as far as all the electrical safety posts go, I can understand the worry with liability from the mods of the sight but honestly - if you are so stupid that you do not know that 240V electricity is dangerous and can kill you then you deserve what you get. In my opinion the constant posting is the same as if when someone posted that they were going down to Bunnings to get parts that a hundred people should warn them about how dangerous a car can potentially be.

I dont mean to piss anyone off with this post, I just wanted to point a few things out in a constructive way. I hope everyone will forgive my rant and have a merry christmas

Re: Mega Popper

Gday Aaron....

Have a search on this forum and on Google for a "Fluid Bed Roaster". This is really what youre talking about and there are some very effective and intriguing designs to be found and used by home roasters here and overseas.

All the best mate.... 8-)
