Notes & Errata Problem with SiDRADIO & CLASSiC DAC cases Stereo LED Audio Level/VU Meter, June & July 2016: in the circuit diagram on page 36 of the June 2016 issue and the overlay diagram on page 77 of the July 2016 issue, the 12kΩ and 1.5kΩ resistors associated with REG2 are swapped. This error has been carried over onto the PCB silkscreen as well. Install these resistors in each other’s marked positions to get the correct 11V output, otherwise the unit will not power up. I’ve ordered all the parts off your website to commence construction of the SiDRADIO Project (October/Nov­ ember 2013) and hence have already committed to spending nearly $100 on this project, only to discover this morning that the ABS instrument case no longer exists on the Jaycar website and a good Google search this morning on Altronics and RS Components and other search results reveals that there is no case that is 225 x 165 x 40mm available anywhere. The closest I can find for a reasonable price is www.altronics.com.au/p/ h0312a-ritec-220lx165wx60hmmip65-sealed-abs-enclosure/ but it is 220mm x 165mm x 60mm! If you’re going to advertise and promote this kit in the current edition of SILICON CHIP and continue to sell the kit on your website why then have you not made the case available to order from your website? Surely other people have experienced this problem to source the instrument case. (C. C., Mendooran, NSW.) • The case is actually available from Altronics, Cat H0474 – see www. altronics.com.au/p/h0474-40x225x 165mm-abs-grey-black-instrumentcase/ The same case was also used in our CLASSiC DAC project from the SC February to May 2013 issues. Touchscreen Appliance Energy Meter, August-October 2016: in the parts list on page 33 of the August 2016 issue, an incorrect part number was given for the Yunpen YF10T6 mains filter. It should be Jaycar Cat. MS4000. Ask SILICON CHIP . . . continued from page 103 that there is no risk of turning it on! In fact, it might be easier to tap into the serial bus between the GPS receiver and processor and simulate the NMEA data from the GPS chip. It would probably be rash to state that it could not be done but if one was to indulge in such an exercise, we would want a somewhat more useful application than trying to find Pokemons. Mind you, your suggestion would at least have the advantage of avoiding the situation whereby people wander across pedestrian crossings while totally fixated on the image on their smart phones, thereby risking death or serious injury. Next Issue The November 2016 issue is due on sale in newsagents by Thursday 27th October. Expect postal delivery of subscription copies in Australia between 27th Octber and November 11th.
