Notes & Errata Touch Lamp Dimmer, June 1989: As noted in the article, the revised version of the SLB0586 does not require diodes D1 and D2 but they will not affect circuit operation if they are left in. However, now that the revised chip has been released, as SLB0586A, it has been found not to work in the circuit as published. To make it work, two components must be changed. The 680k0 resistor must be swapped for a 0.33µF capacitor while the .0022µF capacitor should be swapped for a 1ookn resistor. These components will fit without any modifications to the PCB pattern being required. If your kit has the original SLB0586 IC, no circuit changes are necessary. Studio Series 32-Band 1/3 Oct- ave Equaliser, March, April 1989: one of the four 220µF electrolytic capacitors shown on the main equaliser in the wiring diagram (Fig.1(b} on page 48 of the April issue} is reversed in polarity. The capacitor in question is connected to pin 4 of IC2. Ultrasonic Car Burglar Alarm, July 1989: the wiring diagram on page 63 shows one side of the siren connected to chassis. It should connect to + 12V, as shown on the circuit on page 61. Garbage Reminder, August 1989: the .047 µF supply bypass capacitor shown between IC6 and IC7 on the wiring diagram of page 50 is shown as 0.1µF on the circuit of page 49. The value is not critical though and either 0.lµF or .047µF is OK.

SILICON CHIP is a great magazine. I like the Vintage Radio section and the Serviceman's Log. What happened to the Technology Letters? (A.R., St George, Qld}. • Tunnel diodes have become very rare. In the 1960s they were regarded as the wonder diode but very largely they look to have been a solution looking for a problem. Their special claim to fame is that they have a "negative resistance" characteristic which enables them to be used as amplifiers or oscillators right up to microwave frequencies. Now, most of the applications for tunnel diodes appear to be fulfilled by more conventional devices such as microwave transistors and Gunn diodes. General Electric was at one time the major manufacturer of tunnel diodes but this is no longer the case. However, we have been in contact with the agents for General Electric, GEC Components, and they have indicated that they may be able to source tunnel diodes, depending on the type number and quantity required. If you want to make further enquiries, you can contact GEC Components by phone on (02} 887 6222 or by fax on (02} 805 0272. Remote Control ctd from page 8 secure and military designers are constantly searching for better ones. Some of the more complex included frequency hopping, chopped chirp, exotic encoding and above all else, making the vehicle as intelligent as possible, so that it can perform its task with as little outside assistance as possible. All of this and more will be discussed in columns to come. There'll be simple explanations covering the installation of the equipment into models, care and feeding of nicads, and the correct use of servo arms, plus the exotic. It should be a lot of fun. See you next month. ~ The Way I See It ctd from page 90 ly turned up in disposals stores for 50c each or three for a dollar!

Does one protest that the $300 miracle healing machine is just a con and refuse to proceed any further with the farce? "Knowing the lady as I did, I replaced the crunched diodes with three new ones and assured her that they were a close equivalent to the originals. And of course, as soon as she turned it on, she noticed the difference!" K.W. observes that "thousands of electronic enthusiasts have pulled apart discarded computer boards. How many can claim that they've actually repaired one?" ~ OCT0BER1989 111
