4-Oscillator Synthesizer
For this project, build a slightly-different square wave oscillator on each of the CD4093's Schmitt Trigger circuits. Then, send them all to an operational amplifier - and onward to an output jack.

Charge Pump
With this charge pump (DC pump, volt pump, power pump...) you can have -9V and +18V from a +9V voltage source. Use the -9V output to get a dual power supply or power up effects with positive ground (Fuzz Face, Tone Bender...). Use the +18V output to give headroom to an overdrive. POWER SUPPLY CHAIN WITH POSITIVE GROUND PEDAL A positive ground pedal cannot be directly connected to the power supply in chain with your other negative ground pedals. You can use this PCB to build a voltage inverter and power your positive ground pedal in chain with the rest of your pedals. PCB

HC-SR04 ULTRASONIC RANGE SENSOR
How to set up the Hc-SRO4 Ultrasonic Range Sensor I got 2 of these a week ago there great but there not much on how to set them up so I figured I share how I did it. First off you have to wire it up which from what I have read people was doing it wrong more then once. So here is how I got it to work . I added the serial file so you can use the Serial Monitor to get reading in cm. The zip file has all you need to get this work. Pin 9 is used for trig pin 10 is used for echo. Vcc to 5 volt pin on the arduino. And gnd to gnd on the arduino. Here a picture to make it easy Great little range finder at great price The files you need to add to the arduino ide are here http://sites.google.com/site/be80be/be80be-pic-ing-howto-s/hc-sr04-ultrasonic-range-sensor/HCSR4DemoArduino.zip?attredirects=0&d=1

Mailbox Alert
This is a simple two transistor latching switch that turns on a 555 timer circuit to flash an led. The entire circuit including the battery pack fits perfectly inside an Altoids tin. I mounted the tin in the back of the mailbox with the reset switch and led mounted thru the back of the mailbox. The triger wires were siliconed to the top inside of the mailbox with the trigger switch attached to the inside front against the mailbox door. When the door is closed, the door pushes against the lever on the switch and opens the trigger switch. When the door is opened, the switch closes and trigers the circuit. The circuit can be trigered over and over without reseting the circuit. With the door closed and the reset switch puished, the circuit returns to the standby state. The current draw in the standby state is only a few microamps so battery life will be long. It's cheap, simple and could serve many purposes. Attached are pics of project, circuit and parts list.

Modular PSU
This is a simple power supply with little distribution board, which gives you +/-12 (or even 15, if you want to) and +5 (optional). You can brake the board, if you want to place PSU and distr. board on distance. Also you can connect souces to CV and Gate buses. It is not very useful for most modern modules, but if you creating your own stuff, you can really improve commutation. LM3x7 have to be on the heatsink, 7805 may be in thermal (not electrical) contact with ground plane.

Remote control checker
It would be hard to find a project with less components than this one. Sometimes infra-red (IR) remote controls develop problems with the keypad. When repairing them, it is hard to tell whether or not it is transmitting because the IR light is invisible. This tiny little project responds to the IR light pulses and blinks a red LED as they are received. All that is required to complete this project is to solder all the components onto the circuit board. Please be careful to ensure that the red LED is on the left-hand side, and the black phototransistor is on the right. Leave their leads about 5mm long. The "flat" parts of those devices must face each other. To use it, point the remote control down at the phototransistor from about 50mm away. The LED will blink brightly each time it receives an IR signal. When not in use, keep the project in a dark place and the coin cell will last for many years.

Stratoblaster
This classic DIY pedal is the Stratoblaster, a simple and effective booster. It is perfect to drive a tube amp or give presence to the solos. At high boost levels, it will give a nice and warm saturation. PCB

VibroPunk Sequencer
VibroPunk Sequencer This is an intermediate level electronics project. You have to be able to read a schematic and transfer it into real world components and connections. There is no premade circuit board, it uses a blank experimenters circuit board which you have to lay out yourself using the schematics and my pictures. You also need decent soldering skills. That said, it's not too hard if you take it one connection at a time and double check your work. If you can read a schematic and solder, you can build this. Let's look at the parts list...

ZEN
Effect type: overdrive Pedal description Rated as one of the best guitar overdrives, this DIY project is the ZeN and is based upon the famous Zendrive. The board of this project is designed to fit in a 1590A enclosure or similar, but if you haven't previous experience we recommend to build the project in a 1590B or 1590BB enclosure. Controls
