Rush DIY, Timmy



yung rush mo, malinis ko nang gawa yan HAHAHAHA

Pasensya na sa shameless plug. I was once part of this group building my own pedals. Unfortunately, creating pedals wasn't really my forte kahit gusto ko man ibalik ung hobby na un.
Shout out to this group and especially to cacophony for teaching me.

Pasensya na kung epal ako ngayon, pero gusto ko parin mag stay sa grupo na ito. Hindi man sa pag gawa ng pedals. Pero sa pag supply ng DIY parts bilang pasasalamat

Sana tankilikin niyo! My store is opening soon. Isa isa nang dumarating supplies ko. At isa isa ko narin snshoot

Ive been developing e-commerce website for years now.. And for the past 5 months, I have been building one specifically for this one.
A modern built online store for DIY pedals is coming your way. Hope you guys will like it once I launched

hey pao! hope you'll carry the ICs and components na hard to find :) loads of luck brother!

stay away lang sa mga contact cleaners na may "silicone residue".. after a while gamitin, sure tutunawin ng liquid-based material yun mga dumi.. kaya in an instant magiging ok ang connections.. but after days matuyo yun liquid material.. matitira is yun gooey silicone compound akala mo gel.. then after how many days magiging matigas ito.. mistulang asin.. next thing you know may noise na sa audio line mo..  :-(

so i would prefer cleaning it with a contact cleaner na walang silicone residue.. kasi from the word itself "CONTACT CLEANER".. it was really meant for things with frequent contacts like "hinges" "gears" etc.. now silicone is a good absorbent of "heat".. so contact cleaners tend to leave silicone to avoid friction after the liquid material cleans all oxidized dirt such as rust etc..

now sa mga connectors and switches, most especially dumadaan ang signal (audio line).. silicone are not a very good conductor.. in fact insulators sila.. so they will act as dirt between connections.. and so it may or always introduce cracklings or electrostatic noises..

so it is best to use alcohol-based cleaners because it evaporates easily aside from a good cleaner too..

try denatured alcohol..

awesome bugg fx.. i opened your photo in another tab/window and zoom in to find an inscription "PedalPCB.com" their pcb templates resembles that is yours or bugg fx as you were saying.. ganda bro thanks for these, very tempting!

good thoughts!

Ano pong use ng Vcc at diodes sa output ng pedal? Salamat po.

Vcc <-----|<---------●---------|<----------- Gnd

Vcc refers to the voltage connected to the collector of a bipolar transistor (npn).. not unless you mean Vc which refers to voltage relative to the ground..

though mukhang diode bias but usually nasa input yan ng isang class ab or push-pull amplifier and medyo baliktad ang symbol or polarity..

it's quite new for me  :-(

incase that's a diode biasing.. check mo each diode's current leakages or voltage drop.. pareho dapat if you want a perfect bias..

I've seen that being done near the input jack, but not the output. At certain boost settings of an overdrive, the diodes kick in to make sure the level stays at a certain range, and not any more than that, kind of like clipping diodes.

the purpose of bias if it were the purpose (class ab/push pull amp) → is to cut gain current.. now gain current on input signals would mean a high transconductance and so distorted output signal.. so it was meant to clean output signal of the amplifier.. every electronic parts has it's capacitance, inductance & resistance.. just like this diode say that is 1N4001 having 0.05mA to 1mA leakage current at 50V is 1MΩ to 500KΩ.. where as → if both diodes are at it's peak leakage current it will yield 25V @0.025uA

as to diode clippings → without the other diode connected to Vcc.. puwedeng negative diode clipping.. diode clippings are limiters.. as to negative diode clipping it will limit the negative half cycle of the sinusoidal waveform of the output signal..

I see, thank you for the explanation. I first saw that when I was reading my amp's effects loop schematic, and mistakenly thought it to be a way to prevent the signal from going over a certain level.

for biasing, aside from keeping a quiescent point to make bjt active, efficient & clean.. it's also a way to establish input impedances..

Hopefully mas luminis pa ang wiring ko sa future!
