Welcome - Please Read

Welcome. I wanted to provide stripboard layouts I've made to help people new to electronics and even the more experienced get into different aspects of electronics.

I verify the layouts before I post them.

MXR Hot Tubes Stripboard Veroboard Layout - Craig Anderton Tube Sound Fuzz Variant

I couldn't find any information on this circuit - I found the original schematic on the free info society website but literately 5 minutes ceaseless searching on google brought up nothing about the MXR version. Anyway I redrew the schematic because the original was terrible, then laid it out and built it.
it sounds pretty cool. unfortunately I ran out of space to upload a sound sample to "soundcloud" but I imagine it sounds similar to the Craig Anderton version.

anyway enjoy.

Onboard Guitar Preamp Drive Stripboard Veroboard Layout

This is a little preamp to go inside your guitar rather than as an external pedal which is why it has no controls - feel free to add your own of course!
in the sound sample I recorded the same thing a few times - 1st with the guitars volume at quarter way 2nd halfway and 3rd full way up.

last of all - this is the 88th stripboard layout which is a special number to me cause I'm a big back to the future fan !

PCB Silkscreen Designators

this isn't a stripboard post for a change (though one is coming soon). however it is useful to know what I'm about to write if you salvage parts or want to fix electronic items.

on PCBs (and other electrical installations) you will often be confronted with silkscreen designators like shown below (the white writing on the board)

here is a list of what each abbreviation stands for.

A - Separable assembly or sub-assembly (e.g. printed circuit assembly)
AE: Aerial, antenna
AT - Attenuator or isolator
BR - Bridge rectifier
BT - Battery
C - Capacitor
CR: Diode (see D)
CRT: Cathode ray tube
CN - Capacitor network
D - Diode (including Zeners, thyristors and LEDs)
DL - Delay line
DS - Display
DSP: Digital signal processor
F - Fuse
FB or FEB - Ferrite bead
FD - Fiducial
FL - Filter
G - Generator or Oscillator
GN - General Network
GDT: Gas discharge tube
H - Hardware
HIC - Hybrid Integrated Circuit
HY - Circulator or Directional coupler
IC: Integrated circuit (see U for link)
J - Jack (least-movable connector of a connector pair) | Jack connector (connector may have "male" pin contacts and/or "female" socket contacts)
JP - Link (Jumper)
K - Relay or contactor
L - Inductor or coil or ferrite bead
LA: Lightning arrester
LS - Loudspeaker or buzzer
LCD: Liquid crystal display
LDR: Light-dependent resistor
LED: Light-emitting diode
M - Motor
MCB: Miniature circuit breaker
MK - Microphone
Mic: Microphone
MOV: Metal oxide varistor (See RV for Link)
MP - Mechanical part (including screws and fasteners)
Ne: Neon lamp
P - Plug (most-movable connector of a connector pair) | Plug connector (connector may have "male" pin contacts and/or "female" socket contacts)
PS - Power supply
PLC: Programmable logic controller
PZ - Piezo Buzzer
Q - Transistor (all types)
      FET: Field-effect transistor
      JFET: Junction gate field-effect transistor
      MOSFET: Metal-oxide-semiconductor field-effect transistor
      BJT - Bipolar Junction Transistor NPN PNP HBT

R - Resistor
RL - Relay
RN - Resistor network
RT - Thermistor
RV - Varistor
S - Switch (all types, including push-buttons)
SCR - Thyristor
T - Transformer
TC - Thermocouple
TH - Thermistor
 - types of thermistors are..
   PTC - Positive temperature coefficient - the resistance rises with increased heat
   NTC - Negative temperature coefficient - the resistance decreases with increased heat

TUN - Tuner
TP - Test point
U - Inseparable assembly (e.g., integrated circuit)
V - Vacuum tube - Or VALVE!
VR - Variable resistor (potentiometer or rheostat)
X - Crystal
Y - Crystal or oscillator
Z (or ZD) - Zener diode
IEC Mains connectors (image from unknown - if you know let me know so I can cite)
