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. It is also a great help at keeping little surprises out of your lawn left by the neighbor’s pets. I

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. We will begin with the IC marked NE555, U1. This is a simple, free running oscillator circuit which is used to generate the lower frequency warble rate of the signal. This rate var

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. If a problem does occur, the manual will lead you step by step through the troubleshooting guide until you find the problem and are ab

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. You will want to use the parts layout diagram to assist you in finding where the components go. For each part, our word "install" always means these steps: 1. Pick the correct part valu

❒ 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. Install R16, a 2.2K ohm resistor (red-red-red). ❒ 13. Install R1, a 22K ohm resistor (red-red-orange). ❒ 14. Install R12, R13, R14, and R15 all 6.2 ohm resistors (blue-red-gold). ❒ 15.Install R1

❒ 23. Install C3, a .1uF disc capacitor (marked .1 or 104). ❒ 24. Install C8, another .1uF disc capacitor (marked .1 or 104). ❒ 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

Bend the capacitor over so that it is lying down on the board and solder both leads (with the cap lying down you should have plenty of room to solder it in). ❒ 35. Flip the board back over and locate S1, the SPDT power switch. It is the 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 th

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” SOUNDS. THIS UNIT CAN CAUSE PERMANENT HEARING DAMAGE. ❒ Turn on the power. The LED should light and you should hear an annoying, high pitched whine. If so,

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. ❒ soldering; solder bridges and cold solder joints are two of the most common problems we see on kits returned for repair. You shouldn’t need a mag

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. This is due to the fact that as they age, domestic dogs lose some of their high frequency hearing. (That’s why Old Yeller doesn’t seem to hear me when I whistle for him!?!) CATS: Cats are
