Page 4: Introduction
INTRODUCTION TO THE RB1 RAT BLASTER This is a practical project for people with problems with furry intruders in their yard, not just rats. The Rat Blaster is useful in repelling all kinds of wildlife. The list includes deer, dogs, cats, all rodents, and even some insects. This is the safest, most effective way to repel animals from eating your shrubbery or burrowing in your carrot patch. -
Page 5: How Does It Work
HOW DOES IT WORK? Here is where we get into a little circuit analysis. If you just want to plug it in and start scaring off critters, you can skip this section. Otherwise here is some insight into why and how this RB1 works. We will use the schematic located at the center of the manual to analyze the circuit. -
Page 6: Learn As You Build
NOTE TO NEWCOMERS: If you are a first time kit builder you may find this manual easier to understand than you may have expected. Each part in the kit is checked off as you go, while a detailed description of each part is given. If you follow each step in the manual in order, and practice good soldering and kit building skills, the kit is next to fail-safe. -

Page 9: Construction
CONSTRUCTION OF THE RAT BLASTER: Sort out your parts to begin with, making sure you have all of the parts required. You can use old egg cartons to hold various parts to make them easier to find. We will begin building the kit starting with the lower profile parts to make it easier for us to mount them. - Page 10 11. Install D1, the 1N4002 power diode. This diode prevents the possibility of someone using the incorrect power supply and inadvertently connecting the power backwards. Make sure the banded end of the diode (cathode) is installed in the same direction as shown in the parts layout diagram. 12.
- Page 11 25. Install C2, the last .1uF disc capacitor (marked .1 or 104). 26. It is time to install the transistors, starting with Q3, a 2N3904. Transistors have three legs and must be mounted correctly. Notice that the part has a flat side. Orient the flat side as shown on the parts layout. To install, slide the legs through the circuit board and push the component as close to the board as possible without straining the leads.
- Page 12 smaller of the two switches and has six leads. Press it firmly into the board and solder all six leads. 36. Install S2, the 3PDT power setting switch. After pushing firmly into the board, solder all eight connections. 37. It is now time to install the hookup wire that will connect your completed board to the speaker.

Page 13: Initial Testing
INITIAL TESTING: Connect a suitable 12 volt supply to J1- either 12 VAC or 12 VDC ( positive tip). Set the frequency range switch to LOW. BEFORE turning on the power, please read the WARNING below (also on the back of the case) WARNING TO ELIMINATE ANY POSSIBLE RISK OF HEARING LOSS, AVOID NEARBY EXPOSURE TO THE “RAT BLASTER”... -
Page 14: Troubleshooting
TROUBLESHOOTING GUIDE: If your RB1 does not work at all, recheck the following: correct orientation of diodes, electrolytic capacitors, ICs and transistors. resistor color codes; 2.2K and 22K resistors are easily confused. The orange and red color bands look the same under certain conditions. This is also true for 4.7K and 47K resistors. - Page 15 USING YOUR RAT BLASTER: Certain animals are affected by different frequency settings and other factors that you can change to repel the pests that are bothering you. The information below should help you get the best results from your Rat Blaster. DOGS: Dogs respond best to the low frequency setting.
