I think it is better to leave the thermometer out. I wasn’t able to correlate temperature indicated by the thermometer to the stones temperature or the oven inside temperature. There are too many factors that affect temperature measurement by the thermometer. The user is better off to use an IR gun. Even if you don’t have an IR gun you can tell the stone is ready by simply sprinkling couple of drops on the bottom stones, if it disintegrates immediately, the oven is ready for baking.
I n regards to the logo, I may not be able to add on for the first 2 to 300 ovens due to minimum requirement to custom a logo. Plus I have not found a good source to make them. My plan is to have premade whole for it (will be covered) , and send the logo later to owners to install.
My original plan was to use kickstarter to fund minimum order for the oven and couple accessories (stones, peels, cutter…) . But all these accessories require minimum orders in thousands. It will allow me to offer these accessories at lower price than the one available in the market. But there is a risk of my project failing if not funded. So I am thinking to delay launching the oven / accessories on kickstarter till January or February and start small , by placing a small order (100) for the oven / stones. This should give some momentum going for the oven at least before launching on kickstarter.
By placing small order my cost will be much higher (material cost, shipping etc..), regardless, I am planning to set my introductory price for the first 100 ovens so it will be equal or less than the introductory price on kick starter. My profit will be less than 50% for the first couple of hundred ovens, but I think it will be more conservative way to get started.
