The Most Beautiful Homemade Device I’ve Ever Seen

I covered British electronics hobbyist Rupert Hirst’s lovely freeform headphone amp back in December, when it was still “just” a skeletonized circuit. Now he’s finished up by casting the meticulously-constructed electronics in clear resin, with equally meticulous care. He built a custom mold from 1.5mm cardstock, carefully sealed the jacks against resin infiltration, and mounted the wire frame inside the mold. After pouring the resin and allowing it to cure, he squared up the block on a belt sander, chamfered the edges with a router, and finally polished everything up with wet/dry sandpaper and Brasso. Rupert’s aesthetic—doing relatively simple things with extraordinary attention to detail—is always inspirational to me.

TCPIP and WIFI over a simple serial interface

April 4, 2012 in Chips by DP | comments

Sjaak tipped us to the MCW1001A, a TCP/IP stack and WiFi management IC with a simple serial interface. It stands between your project and a MRF24WB0MB WiFI module so you don’t have to mess with a full TCP/IP network implementation.

MCW1001A is a companion chip to the MRF24WB0 802.11 module. It provides simple socket based method of sending and receiving data from the MRF24WB0 802.11 module. The MCW1001A has an on-board TCP/IP stack and 802.11 connection manager to simplify the connection between a wireless network and the TCP/IP stack management. After the initial configuration is set, the MCW1001A can access the MRF24WB0 802.11 module to connect to a network and send/receive serial data over a simple UART interface from the Host controller.
