This notation is designed to be relatively easy to write. This is achieved by not drawing ultra complex ASCII art boxes of every component. It would be slightly more readable if we did that, but prioritizing the writer here.
Two wires are only joined if
but the following are:

is given. E.g. the following two wires are not joined:

Simple symmetric components:

and|
: wireA
: AC source. Parameters:e.g.:Hz
: frequencyV
: peak voltage
A_1Hz_2V
G
.C
: capacitorG
: ground. Often used together withD
, e.g.:D_10---R_10---G
L
: inductorMICROPHONE
. As a multi-letter symmetric component, you can connect the two wires anywhere, e.g.---MICROPHONE---
| MICROPHONE |
SPEAKER
R
: resistorX
: Josephson junction
Asymmetric components have multiple letters indicating different ports. The capital letter indicates the device, and lower case letters the ports. The wires then go into the ports:
aDc
: diodeSample usage in a circuit:a
: anode (where electrons can come in from)c
: cathode
--aDc--
| a D c |
D
:--cDa-- | Dac-- | Dca-- | --caD
pDn
: DC source. Ports:E.g. a 10 V source with a 10 Ohm resistor would be:p
: positiven
: negative
+---pD_10_m---+ | | +----R_10-----+
G
. We can also omitp
andm
in that case and assume thatp
is the one used, e.g. the above would be equivalent to:D_10---R_10---G
sgTd
: transistorSample usage in a circuit:s
: sourceg
: gated
: gate
---+ | --sgTd--
| g --sTd--
| --Tsgd-- |
dIs
: electric current source. Electrons leave froms
and go intod
pVn
: Voltmeter. Ports:If we don't need to specify explicit positive and negative sides, we can just use:p
: positiven
: negative
---V---
Optionaly, we can also add the sides as in:
Numbers characterizing components are put just next to each component with an underscore. When there is only one parameter, standard units are assumed, e.g.:
means:Micro is denoted as

C_1p R_2k

+-----+
- a capacitor with 1 pico Faraday
- a resistor with 2 k Ohms

.Wires can just freely come in and out of specs of a component, they are then just connected to the component, e.g.:
means applying a voltage of 10 V across a 10 Ohm resistor, which would lead to a current of 1 A
