In case it isn't, it must be a privacy thing at my side.
I can see the pic with a full firebox and matches box
BTW. Can you see my 2 pics of the DSR implementation in a cook stove a few post earlier ? They are linked from google photos which supposedly offer ssl certificate thus they shall be displayed if the solution Trev's found is the cause.
Jura, I can see your pictures earlier in the thread, no problem. My pictures are on an old website, not https as Trevor (thanks!) rightfully assumed. I asked my provider whether it would be safe to use Cloudflare to solve this issue.

I managed to fix mine by getting a free SSL cert from here: www.sslforfree.com/ I followed the youtube tutorial linked on that page to create and install it. It has to be re-done every 90 days, so probably easier to pay the 30 euro a year to have it done by your website host.

Peter what's your opinion on making the top box wider to make it a more suitable oven without changing the exit? Sorry if this has already been asked. Perhaps this would have adverse effects on the air frame with added drag around corners for a larger top door.
I'd think it wouldn't make any difference making the top box wider. The air frame should be the same and the top door separate from that air frame somehow. I'm only guessing here, based on what I know about Yasin's BatchBlock.

Here's a link to a sketchup(v8) of the top box of the DSR2 widened to a better oven width. The center tube is connected open to the lower door frame to act as the "balancing pipe". The upper frame is not open to the center tube. This is drawn as a 7 inch system.
OK guys, I think I solved most of the picture problem. I've mirrored the old site on one that has a https predicament and used a good part of the past day to amend links. Being a moderator has its advantages, I am allowed to edit every and any post without a problem. Some pictures in older threads are linked to pictures in another, Dutch forum which hasn't an SSL at the moment, so those pictures aren't showed (yet).

No plans for another experiment season as yet. I assume size of the gap between cooktop and top end port should be something between 10 cm (4") and 15 cm (6"). Not sure of that one, the upcoming workshop in Belgium could be done with a 15 cm top gap without problems.
Hi Orange If you open side of the top box, then it will be very very close to the design of the batchblock. Just a straigth version of the batchblock.
It seems to me that it doesn't work as well as the DSR2 in term of stability under 13,0 % O2. I use to think that the downdraft part would have the same effect as the second port, but my last session of experiments led me to think the opposite.
Regarding the combustion during all the other phases of the burn, it seems to be quite the same : excellent.
Since Ronyon asked about the possibility to have an object inside the top box, I placed two bricks on top of each other in the top box/oven. There's no point having an oven while there can't be anything in there, don't you think? I loaded it up to 2/3, same end port, same fuel, no wind and foggy outside ... and lit the fire. And I sat down to wait for the thermal runaway to appear. And it didn't, much to my surprise. Even the fireball wasn't as pronounced as I expected.
Given how well this worked, I'm puzzled as to why all the experiments mentioned after that used a block (or tripwire) fixed to the ceiling: there's no mention of any further experiments with floor-only obstacles.
I imagine that in most ways of building, it would be easier to make the system with the block on the floor rather than on the ceiling. The final DSR2 has the "stumbling block" in the ceiling though. (Maybe Peter tried them on the floor and found they weren't as good, but didn't write about them...)

(Maybe Peter tried them on the floor and found they weren't as good, but didn't write about them...)
There's a reason for all this. In order to have the floor of the expansion box/oven available at all times I tested this setup with a number of blocks at the ceiling. Also, a combination of stumbler and bricks on the floor has been tested with very close to equal results. So the design is usable as an oven but the block, tajine, römertopf or whatever on the floor isn't necessary for the functionallity of the thing. So now there's a choice: either you use it as an oven all the time, now and then or not at all, the efficiency and stability of the burn is still the same.
In case the floor block should be there at all times you'll need to take the bricks out in order to shove the food in. In my opinion, this is a very cumbersome arrangement, prone to mistakes. So I chose to build this important functionality in the design in a different way.
