Are 1um masks that expensive (compared to the rest of setup)? Or is it has more to do with turnaround times?<br><br>Can you share details of a light source and resist? One important thing will be to pick light source that will not burn the LCD matrix, and will not be absorbed by the glass much. Making a custom made LCD with special materials might not be that cheaper that sticking with masks for the beginning.<br><br>It will be truly great if one can just replace the mask with LCD with no extra work<br><br>Sent from my Huawei Mobile<div class="quote" style="line-height: 1.5"><br><br>-------- Original Message --------<br>Subject: Re: [Libre-silicon-devel] [OT only slightly] STEAM Camp<br> OpenSourceEcology 22jan2020 for 9 days<br>From: David Lanzendörfer <leviathan@libresilicon.com><br>To: Libre-RISCV General Development <libre-riscv-dev@lists.libre-riscv.org>,Linux on small ARM machines <arm-netbook@lists.phcomp.co.uk>,Libresilicon-developers@list.libresilicon.com,fosdem@lists.fosdem.org,libresilicon-developers@list.libresilicon.com<br>CC: Alasdair G Kergon <agk@fosdem.org>,Marcin Jakubowski <marcin@opensourceecology.org><br><br><br type="attribution"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi<br>My idea was to use an LCD plus a lens system in order to build a mask less<br>stepper unit for manufacturing semiconductors.<br>This way the costs for the mask sets would fall away and you would suddenly<br>be able to provide something like a pooling service for semiconductors.<br><br>What do you think?<br><br>Something worth combining your brain power over in those said 9 days?<br><br>Cheers<br>-lev<br><br>On Tuesday, 31 December 2019 4:42:10 PM HKT Luke Kenneth Casson Leighton <br>wrote:<br>> apologies for the cross-list post, the topic is very likely to be of direct<br>> or indirect interest, please do share elsewhere, however for questions<br>> please do reach out directly to Marcin from OSE rather than crosspost<br>> replies!<br>> <br>> the OpenSourceEcology Project is running a hands-on real-time collaboration<br>> and training course for 9 days that happens to have one of its camps in<br>> Ghent, Belgium, only around an hour by train away from FOSDEM and running<br>> up to overlap with FOSDEM only on its last 2 days, Feb 1st and 2nd, 2020.<br>> <br>> https://www.opensourceecology.org/steam-camp-january-2020/<br>> <br>> Marcin's Ted Talk is here:<br>> https://www.ted.com/talks/marcin_jakubowski_open_sourced_blueprints_for_civi<br>> lization?language=en<br>> <br>> it is the beginning of a practical real-world bootstrap process for a<br>> modern civilisation and actually uses and puts into use everything that we<br>> love about FOSS and FOSH.<br>> <br>> participants will get to actually *make* a 3D Printer, a CNC milling<br>> machine, then use those to fabricate an Arduino PCB which... you get the<br>> idea.  a battery operated welder will also be one of the hands-on projects.<br>> <br>> Alasdair, an idea just occurred to me: can we discuss privately, they are<br>> doing "remote" collaboration: is there room / time for OSE to book a<br>> workshop by remote link, for two reasons: one in case FOSDEM attendees are<br>> interested to see what is going on, but secondly, if anyone who attends<br>> STEAM would like to keep in touch whilst attending FOSDEM?
