Made a new application for the Red Bokito. The Red Bokito is checking email for every 2 minutes. By sending an email it is possible to switch ON/OFF/TOGGLE the four relays of the board. And after succesfully switching receive a confirmation email. Used 2 socket of the WIZ810MJ, socket 0 is for receiving the commands with POP (PostOffice Protocol), and on socket 1 the confirmation email is done by SMTP. Sample code can be found here: Emailswitcher

The complete stream of commands can be followed by PRINT-statements.

This is the USB controlled Atmega8 microcontroller based power supply. Starting with the Visual Basic and IOCOMP software. FT232RL for the USB connection.

Central Board in it’s case with two Field-devices on their DIN-rails.

“The Making Of” Field-devices. An impression.

After a few proto-types, made an bottomplate for the Red Bokito. This combination called Field-device is used in a

8 opto-couplers are monitored from within a Central Board. This Central Board is capabele of monitoring a maximum of 100 of these Field-devices. An alarm is seen within a few seconds. Top of the Field-device is the Red Bokito, with a special made bottomplate with 8 x PC817 optocoupler and a LED for the heartbeat.

Working straight out of the box… WIZ-iStorage. On the CD a free FTP-program, documentation and some examples. Putting a USB-stick or USB-drive in my network.

First small steps with the Wiznet W5300. Checking the differences between W5100 and W5300. The module used on the Wiz200WEB evaluation board has a Atmega128, 32 Kbytes external RAM, 512 Kbyte external ROM. A few nice examples on the CD, but sometimes you get a bit lost what software to use. Examples in C, using WINAVR and AVR Studio. 6 pin ISP connector on the base-board. Have made an adapter for my 10-pins Kanda programmer to the 6 pin ISP programming socket. Did a recompile of the software and a reload of the microcontroller. All working well. Uploaded a new webpage, running very well.
