<div>I have been using this <a href="https://smile.amazon.com/gp/product/B00XK3ALS0/ref=oh_aui_search_detailpage?ie=UTF8&psc=1" rel="nofollow" target="_blank">https://smile.amazon.com/gp/product/B00XK3ALS0/ref=oh_aui_search_detailpage?ie=UTF8&psc=1</a> for the last 8 years roasting green beans.</div><div><br></div><div>That has the side vents, takes ~30 mins to roast. Works *really* well. I burned the motor out 2 weeks ago. It's discontinued. Thought I should migrate to an arduino based version, hence my questions and asking for advice on what parts I should purchase.</div><div><br><div>Yes, after the roast I dump the beans into a cooling basket.</div></div><div><br></div><div>I have one of these to replace it: <a href="https://www.gopresto.com/product/presto-poplite-hot-air-corn-popper-04820" rel="nofollow" target="_blank">https://www.gopresto.com/product/presto-poplite-hot-air-corn-popper-04820</a><a href="https://smile.amazon.com/gp/product/B00006IUWA/ref=oh_aui_search_detailpage?ie=UTF8&psc=1" rel="nofollow" target="_blank">https://smile.amazon.com/gp/product/B00006IUWA/ref=oh_aui_search_detailpage?ie=UTF8&psc=1</a></div><div><br></div><div>Given that new information, would it change the proposed design?<br></div><div><br></div><div>It will be much better if I can control the roasting process though. Without control I get a few over roasted beans.</div><div><br></div><div>Thanks for everyone's help.</div><div><br></div><div><div>Craig</div></div></div><div id="ydpea34199cyahoo_quoted_0933019641" class="ydpea34199cyahoo_quoted"><div style="font-family:'Helvetica Neue', Helvetica, Arial, sans-serif;font-size:13px;color:#26282a;">
