PIR Circuit board with photo resist washed off the area to be etched
(I didn't actually end up using this one as it was a little over exposed)
my 1st roll of film developed with CAFFENOL-C. a combination coffee, sodium carbonate & vitamin C.
The recipe I used was
15g instant coffee (6 'rounded' teaspoons) mixed with 150 ml water
8g washing powder (4 'level' teaspoons mixed with 200ml water)
then both combined & 1gm (1/4 tea spoon) ascorbic acid (aka vitamin c) added.
I devloped a roll of lucky100 for 9 min @ 20 deg c & fixed with agfix. Although it worked It was underexposed; mainly because I pushed the lucky film 1 stop & failed to compensate when developing.
Still the results are interesting enough to have me try devloping with CAFFENOL-C again.
thanks to www.caffenol.org for the great recipes.

I used a craft knife to scrape the cabbage tree leaves so I was left with stringy fibres. When I grouped all the fibres together I found it had quite a springy quality to it.

Natural arch developed in chalk & impure chalk in the Cretaceous of Kansas, USA.
This western Kansas landscape consists of chalk badlands and chalk pillars and a natural arch. The rocks are chalks and impure chalks (e.g., argillaceous chalk and chalky shale) that range in color from whitish to light gray to yellowish. Chalk is a biogenic, calcitic, marine sedimentary rock composed of numerous coccolith microfossils (see: www.soes.soton.ac.uk/staff/tt/eh/pics/lith2.gif). Coccoliths are individual calcareous plates that covered a single-celled photosynthetic marine organism called a coccolithophorid (a.k.a. coccolithophore) (see: upload.wikimedia.org/wikipedia/commons/d/d9/Emiliania_hux...). These beds were deposited in the ancient Western Interior Seaway, a section of ocean that existed during parts of the Mesozoic Era in what is now the American and Canadian Great Plains.

Rock arches are rare erosional features - those developed in chalk beds are even rarer. If a stream goes under an arch, it is known as a natural bridge. If no stream is present, the feature is a natural arch. Along lakeshores, they are called lake arches. Along oceanic coastlines, they are called sea arches. The highest concentration of natural arches on Earth is Arches National Park in eastern Utah.

What's Up?
The cavern formed along fractures that developed as the Capitan Reef was growing. The weight of the reef caused pull-apart fractures: one set parallel to the reef and one set perpendicular. You are standing inside the reef at the junction of two perpendicular fractures. From here, you can see about 1,150 feet (351 m), from the Lower Cave overlook to your left to the Bottomless Pit to your right. Tall ceilings usually develop at fracture junctions, as here, where the ceiling is over 250 feet (76 m) high.
Look up at the fracture junction in the ceiling. You can see a dome leading to the Spirit World-about 800 feet (244 m) of passage above the ceiling,
