-##Sketching through the machine
-
-Finding the elements of the machine through sketching. We started at the bottom and started constructing the machine in our imagination and on paper, thinking through all the problems we could foresee, and trying to draw out conclusions for each.

-Literally getting on the same page. Just not Bea's if you have heavy handwriting (;-) love you girl, amazing tech drawings you do).
-
-##Measure everything
-
-Your measurements are belong to us.
-
-* Measure ~screws, I mean rods~, I mean bolts!
-* Measure sheet materials
-* Measure energy, fresh air and vibe in the room, brew coffee, take walk or burn palo alto if necessary.
-
-We found more problems and questions! Can we – roughly – cut all the pieces we need out of the wood and acrylic we have? 
-
-##Settling on shared terminology & toolology
-
-They might not be correct, they might not be technical terms, but they work for us until they don't. 
-
-* Absolute base layer
-* Profiled base layer (inner and outer)
-* Rods, pipes or bolts
-* Length - Width - Height (OR thickness!)
-* Walls!
-* Escape hatch
-* Closing wall
-* Wiper thingy or squeegee
-* Acrylic wiper-height-adjustment-strips
-* Screw holes
-* Rubber ducking
-* Caliper
-* Decoupeerzaag
-* Straight angle (rechte hoek)
-* Diameter symbol
-
-##Inching in on sizes and settings
-
-* Precise sketch of 2D elements, *softly* drawn...
-* Thinking desired workspace and construction needs in tandem. We want 50x100cm workspace, and reverse-engineered was of assembling from that. 
-* Tests to find the perfect width of the profile in the bottom layer to support acrylic walls.
-* Testing screw, I mean rod, I mean bolt holes (shaft diameter vs. screw wire diameter!) > 5.65 mm for 5.7 mm bolt diameter.
-* Finding settings to laser cut 4 mm acrylic. Finding the safe zone that works across the bed, testing with pieces big enough to let the laser catch up to the set speed (min 10 cm test pieces). Speed 18 power 100. 
-* Tips for resizing array of 7 holes in Rhino file
-* Tools have sizes and limits too: succesful and unsuccesful tools to saw a 200cm acrylic sheet in two to fit it into the lasercutter (which also has sizes).
-
-##Analog is boss: improvised and accidental precision is still precision
-
-* Finding out that the wooden bottom + acrylic bottom equal the height of your outside frame by accident = precision <3
-* Pressing two wooden sticks together with a 4mm thick piece of acrylic in between is a perfectly fine improvised way of achieving a nice and tight 4mm profile. It's snug alright. Boom.
-
-##The main work: communication and patience
-
-Expressing what you mean and making sure the other person understands it the same way and can respond is incredibly complex and time consuming. Considering that we are building a machine and with all talented and capable improvisers but we don't have an engineering background or shared lingo to fall back on! We took up sketching, drawing, note taking, doing build tests and demonstrating with stand-in materials as tactics to turn to when talking and listening were insufficient or too energy consuming for the amount of brainpower we had left. But we also talked a lot of course, about what the words we agree to use, division of tasks, checking in on each other, asking for help, giving compliments and cheering along. We also shut each other up quite a few times, hahahahaha.  
-
-We brushed upon each others limits here and there. Emotions might have been expressed too. But nothing crazy and lots of cookies. And coaching by Bela :)

 We built a prototype for a sheet casting tool to accommodate our needs and desires to produce large and evenly flat sheet materials made of bioplastics such as the gelatine and agar-based ones, and the alginate plastics we made last week. We tested the machine by casting a sheet with alginate plastic. So far, the machine functions and we made a lovely 2mm sheet with it (which shrank a bit)l but could be improved by finding a better solution for keep the walls together – the silicon glue didn’t hold. And also the wiper or squeegee could have a deeper wiping edge so the strips can act as walls. Excess liquid will creep up, and could be contained if the wiper sinks a little deeper by default. Anyway, details details. Here's our working prototype! 
 
+The machine might need some iterations but has potential to allow us to research shrinkage, cast the exact same kinds of sheets, comparing recipes etc etc. Even do small batches of production.

 The process of creating the machine was challenging at first (see below), but as soon as we were on the same page and had a shared understanding of the goals, the technical nitty gritty, and names for things, we took off like a rocket and had a lot of fun even though loads of stuff of course went wrong (and got fixed) along the way. 
 
+##Feedback
+
+Mar: precision thickness was an issue for acrylic even just a few years ago, so nice idea to try this for bioplastics!
+
+Mar: suggested to put a railing to keep the height precise. In the industry they control sheets by iterating and improving the methods for standardizing, so good start. And you're trying different things like textures and stamps so lots more to explore. 
+
+Anastasia: suggested to also include more technical drawings, maybe imagining how this machine might work in industry (more automated). 
+
+Response: Yes! We're working on an IKEA-style construction manual based on our Rhino files. It's taking a little longer though.
+
+Question: How do you put calcium chloride below?
+
+Answer: We don't, it dries very nicely with a beautiful gloss. It takes a little longer to cure because it only cures from the top, but the results are much nicer. It shrinks more than when you cast on top of a fabric though, this is true. But dat shine doe!

 ##Brainstorm
 
 After seeing the many interesting machines during the lecture, we were of course inspired and a little intimidated. We explored these questions: *when is something a machine?*, *when is something a tool?*, *how important is it to us as a group to create a CNC tool this week?*. In order to come to answers, we studied some machines in the lab and how they worked, how they were similar and how they were different. Which parts are interchangeable and which aren’t?
