 6piz7wk | is there a way to calculate it? | 23:31:50 |
| 6piz7wk | i want to do prototype PCBs | 23:31:59 |
 inv41idu53rn4m3 | Resistance is inversely proportional to cross-sectional surface area except not exactly but I don't know how the not exactly part works | 23:32:35 |
| 6piz7wk | o.o | 23:33:09 |
| inv41idu53rn4m3 | do some web searches :) | 23:34:48 |
| 6piz7wk | but i wanted to avoid doing that! | 23:35:32 |
 lispmacs | per the electronics textbook next to my bench, conductivity of a wire varies depending on type of material. Also, the longer the wire, the more resistance. Also, the greater the cross-sectional area of the wire, the less the resistance | 23:57:16 |
| lispmacs | also, most types of wire have more resistance at warmer temperatures | 23:57:44 |
| lispmacs | 6piz7wk: ^ | 23:58:30 |

| 6piz7wk | greater the cross-sectional area of the wire the less the resistance? | 00:00:06 |
| lispmacs | correct | 00:00:16 |
| 6piz7wk | So for prototyping i shouldn't have issues with using a thicker wire for traces? | 00:00:24 |
| 6piz7wk | ... as thicker is more managable by hand | 00:00:30 |
| * 6piz7wk wants to isolate the wires and lay them on a sticky surface | 00:00:48 |
| lispmacs | that is correct | 00:01:02 |
| 6piz7wk | thanks | 00:03:17 |
 CaptHindsight | 6piz7wk: thickness of the traces and their distance from one another and other layers also effects their impedance | 00:27:16 |

 Louwrens | Hi ! Does anyone have a pointer to good documentation / tutorial on Teensy (4) timers/counters ? Examples for beginner appreciated π | 14:03:21 |
