Re: 555 Ticking Sound - How to clear it up?? [SOLVED]

Re: "Murder One" Submini Tube Guitar Amplifier

Resize to 48% should be correct. Those electrolytic look huge. What size are they? I used 11mm x 5mm.

Re: "Little Angel" - Super Simple PT2399 Mini Chorus [documentation]

When I was breadboarding using the PT2399 with delay set very short, I noticed that the delay time 'swooped' down if I disconnected power to the PT2399. Plugging an LFO into the chip's vref pin simulates power being disconnected/reconnected very quickly. It's cheating really.

Re: frequencycentral OHP Transparency Graphic Technique Tuto

The graphics look great, but I don't think I understood everything correctly. I mean, what do you do after cutting the graphic? You just place it on the enclosure with the ink side facing the metal? And that's all? No pressing down? Leave it for how long? Next I give the enclosure a spray of clearc...

Re: LED blinking with LFO causes spikes on power lines

RGB? Colour changing LED? Known to cause nasty spikes. Replace it with a red or green and you're good to go.
