Science stencils
property testing
an illustration of property testing algorithms one-sided error two-sided error
Proteins and cells parts
Antigens, hormones, cell components and other various components I use to build diagrams for immunology, oncology etc.
Pyramid for hierarchical structures
Two pyramids in a 3D-like view with separated levels. You can name the different levels.
RF Components
Here is a stencil for RF/microwave circuit diagrams. These symbols represent signal flow in radio-frequency circuits. They could be used in conjunction with electronics components from the "Electronics Components" stencil, also on Graffletopia. These symbols are based on a combination of symbols in common use. There is a bias...more
SADP
Stencils for drawing Self-aligned Double Patterning.
Satellites
I needed some satellites for some simple network diagrams. They had to have the appearance of floating in the sky, so perspective was important. I set about creating these in Cinema 4D and dropping them into Omnigraffle.
Science apparatus
A selection of science apparatus used in a post 16 class room
Semantic Web RDF Graph Symbols
Symbols used when creating RDF graphs, including classes, object and data properties, as well as RDFS and OWL primitives
sensors, switches, etc. elements electronic circuit symbols IEC 606007
This stencil includes the mainly used sensors,switches and more useful electronic circuit symbols in IEC 60607 standard. The IEC is the International Electrotechnical Comission (IEC) and prepares standarts for all electrical, electronic and related technologies. These Symbols are used in nearly all countries over the world....more
