The ERP software we wrote to manage inventory and synchronize web orders with QuickBooks has been working pretty darn well. It certainly has its issues but for the most part it keeps us 100% on top of inventory. We actually have not taken physical inventory for a very long time. We did formally take inventory last week, and we weren’t too far off. We’ve updated the inventory counts (such that it matches what we actually have on hand) and we’ll take inventory again in a month and see how far off we are then. We made a spreadsheet that in principal should make taking inventory pretty painless – mostly by weighing the various boxes.
Saleae Logic 16 – 16-Channel USB Logic Analyzer! A logic analyzer is a device that lets you watch digital signals in your electronics project. You can watch them real-time or log the data for later perusal. Unlike an oscilloscope, its not good for measuring analog signals – but also unlike an oscilloscope, you can track 16 signals at time! So its a good complementary tool. This logic analyzer plugs into a computer and has easy to use cross-platform software. This makes it small, portable and inexpensive. If you ever have to to debug SPI, i2c, serial, CAN, 1-wire, Manchester, biphase or other digital protocols, this tool is essential!
