This page is a list of some of the gEDA symbols and footprints that I have found it necessary to create - either due to custom requirements/parts or because I could not find such a symbol in an existing library. I make no warranty as to their correctness or their conformance to any gEDA Good Practice guidelines. I have made these symbols to meet my own purposes and to fit into my own designs, and am publishing them in the hope that somebody will find them useful - perhaps even a building block for their own symbols.
I tend to make a fair few of these things, so will upload a couple every now and then when I remember or get some spare time.
For a much more extensive list of gEDA symbols/footprints, I suggest that you take a look through the library at http://www.gedasymbols.org/.
Symbols for gschem.
| Part | Notes | Image |
|---|---|---|
| SCART Connector (21-pin) | Basic 21-pin SCART connector. |  |
| NE602 Mixer | Uses nets Vcc and GND for implicit power supply
connections. Uses label prefix of XU to enable SPICE subcircuit
integration. |
 |
| LF412 Dual Op-Amp | Uses label prefix of XU to enable SPICE subcircuit
integration. |
 |
| L7805 Voltage Regulator (TO220) | Uses label prefix of XU to enable SPICE subcircuit
integration. Ties net GND to pin 2 and also the metal TO220
case - this is expected to be pin 4 by the PCB footprint. |
 |
| LM1881 Video Sync Separator | Uses nets Vcc and GND for implicit power supply
connections. Uses label prefix of XU to enable SPICE subcircuit
integration. |
 |
| Varicap / Varactor | Basic varicap / varactor diode symbol. |  |
| 74390 Dual 4-bit Decade Counter | Uses nets Vcc and GND for implicit power supply
connections. Uses label prefix of XU to enable SPICE subcircuit
integration. |
