HAPPY HOBBYIST Your February 06 issue was great. It had everything I look for in an electronics hobby magazine: interesting circuit projects, microcontroller articles, and new electronics technologies. I especially like T. J. Byers Q&A section. In some of the past issues, there has been too much mechanical construction and workplace psychology articles for me. I hope you continue with this format. It would be good if you printed more of the software listings for the microcontroller projects rather than require the reader to get them online, even if this required the use of tiny print. Bob Lacy Scotia, NY FIGURE FAUX PAS I just wanted to thank all the staff at Nuts & Volts for publishing my "Monitor Indoor/Outdoor Temperature and Relative Humidity with One Device" article. What a terrific job! In checking over the article, there was a "faux pas," and that is on the Figure 5 schematic. Just below the arrow head pointing away from the 1N4001 cathode, the label "+V Supply" got left off. I'm pretty sure READER FEEDBACK your readers will figure it out, but if not, and they ask, you will already know the answer. I caught another error in Figure 5. Somehow, the Visio drawing I sent you is missing a ground connection to the Lcl SHT15 sensor. Definitely my fault! I apologize. Chuck Irwin A corrected schematic file of Figure 5 is available at www.nutsvolts.com WRITER FEEDBACK As a columnist, I always read with interest any published editorials/ letters that are related to my column. Getting feedback from readers, good or bad, is always useful. I never respond because everyone has an opinion and I know that I can never please everyone. However, when words such as "misogynist, prejudicial, and hateful" are addressed to me by "Anonymous," I am compelled to reply. A personal attack is not simply an opinion. To review, the December 05 column of “In the Trenches had a section concerning male and female differences. For the record, in addition to nearly 30 years of experience in engineering design (hardware and software) and engineering management, I also have a BA in Psychology and have taken over a year of graduate (Ph D) courses in the subject.
