12:04 AM Jak_o_Shadows: on another note, why didn't I make this a 3x3 block of connectors?
12:10 AM Jak_o_Shadows: rather than 3 1x3s?
12:10 AM Jak_o_Shadows: with odd gaps in the middl
12:16 AM Jak_o_Shadows: Through now I'm thinking I could make it 4 channel instead
01:10 AM mrdata-: doh
01:11 AM mrdata-: i miscalculated above
01:11 AM mrdata-: you want the RC cutoff much closer to the switching frequency not he transient's frequency
01:12 AM mrdata-: but use the same formula
01:13 AM mrdata-: so the cap would end up larger
01:14 AM mrdata-: maybe 0.5 uF
01:15 AM mrdata-: (assuming 10 ohm is okay for R, tho)
01:16 AM mrdata-: whats the voltage drop across the LEDs?
04:39 PM Phrkd is now known as Phreaked
06:03 PM Coldblackice|4 is now known as Coldblackice
08:18 PM mrdata-: yes i think it does
08:19 PM mrdata-: so then all you need is a cap with good enough ripple current rating
08:20 PM mrdata-: i learned that the hard way
08:20 PM mrdata-: turned a small tantalum cap into a volcano
08:21 PM mrdata-: because i exceeded ripple current.. by quite a lot
09:36 PM rue_mohr: https://twitter.com/RueNahcMohr/status/1330712703988494338 <--- lvdt anyone?
10:09 PM mrdata-: "lvdt"?
10:10 PM mrdata-: Linear Variable Differential Transformer?
10:17 PM rue_mohr: yes
10:28 PM mrdata-: fun
10:28 PM rue_mohr: working quite well
