You can purchase a PDF of the artwork from our website if you want to make the board. But have you considered that there are pink noise apps for smartphones? That really seems like a more convenient solution, unless you don't want to use a smartphone. Large LCD panels for the Explore 100 I'm currently building the Explore 100 project (September & October 2016; www.siliconchip.com.au/Sesiliconchip.com.au ries/304) and have a query regarding the LCD panels that are suitable. On page 79 of the September 2016 issue, under display size and in bold print, it says that the East Rising panel uses a non-standard interface pin-out. Does this only refer to the 8-inch panel or the 5-inch and 7-inch panels as well? I would like to use the largest panel that has the standard interface pin-out. (I. T., Blacktown, NSW) • Geoff Graham replies: East Rising is a company that does not necessarily follow established standards, so you need to have a good depth of knowl- edge and flexibility when using their products. The article mentioned the East Rising 8-inch display as that is the only 8-inch display that we could find and that we tested. If you are considering 5-inch and 7-inch panels then you would be better going with more standard eBay products that will plug straight into the Explore 100. These two examples look OK (note that we have not tested them so we cannot guarantee anything): http://siliconchip.com.au/l/aad1 http://siliconchip.com.au/l/aad2 SC July 2017  103
