Noisy Cricket Amp
PCB design for Beavis Audio Research's Noisy Cricket Amp. Designed to be an onboard amp for an instrument with a speaker in the body. JFET buffer replaced with op-amp buffer from Jack Orman because JFETs are currently hard to find. LED is dimmer than the original because my eyes are sensitive. ☀️ http://beavisaudio.com/projects/noisycricket/ https://electrosmash.com/noisy-cricket-analysis

Pedalboard Headphone Amp
Stereo headphone amp meant to fit in a pedal enclosure for use on a pedalboard. Buffers the signal, then splits it to an output meant to go to a mixer and a headphone out. The headphone amp circuit is applied to the signal before the headphone jack. Originally designed to give the ability to run effects after an amp simulator pedal with no effects loop. Example chain: amp sim > wet effects > headphone amp > mixer.

FG28
The TDK FG series of Multilayer Ceramic Capacitors (MLCC) with dipped radial leads are designed for commercial-grade applications, offering a halogen-free and RoHS compliant solution. These capacitors are available with lead pitches of 5.0mm and 2.5mm, and come in various dimensions ranging from 4.0x5.5mm to 8.5x11.0mm. The FG series includes types such as FG28, FG24, FG26, FG20, FG22, FG23 for the 5.0mm lead pitch, and FG18, FG14, FG16, FG11 for the 2.5mm lead pitch. These capacitors feature a voltage rating of 10V to 630V and a capacitance range from 1pF to 47uF. They are suitable for applications including noise reduction in motors, bypass and smoothing capacitors for switching power sources, snubber circuits, and PFC input filters. The components are characterized by various temperature coefficients including C0G, X5R, X7R, X7S, and X7T, with operating temperatures ranging from -55°C to +125°C. The FG series is available in both bulk and taped packaging styles, designed to meet the needs of general electronic equipment such as AV equipment, telecommunications, home appliances, and industrial robots.
