In recent weeks a number of ESP8266 devices have become available offering more than the previous defacto maximum of 4MB of flash memory. Wemos’s D1 mini pro offers 16MB of flash, and the ESP-100 claims to offer 8MB. To put this in context, the original ESP8266 modules (such as the ESP-01) offered 512KB of flash, […]

The June 23, 1988 issue of EDN included a Maxim Design News insert where we asked “Who in their right mind would choose a computer interface standard that uses ±12V supplies, requires expensive connectors, works over a limited distance, is error prone, difficult to network, and has no current loop isolation?” Yet, here we are

Arthur English’s group at Emory has developed a custom device that they have used for stimulating peripheral nerves optically in anesthetized mice using a standard optical fiber. The device is compact, rechargeable battery-operated, and controlled either manually or by computer using analog input. Essentially, laser LED illumination is coupled to an optical fiber by a
