-HLK-RM04 is a new low-cost embedded UART-ETH-WIFI module (serial port - Ethernet - Wireless network); This product is an embedded module based on the universal serial interface network standard, built-in TCP / IP protocol stack, enabling the user serial port, Ethernet, wireless network (Wi-Fi) interface between the conversions; Through the HLK-RM04 module, the traditional serial devices do not need to change any configuration, data can be transmitted through the Internet network; Provides a quick solution for the users serial devices to transfer data via Ethernet

this seems cheaper than CC3000 but i have no idea

Project development, ideas, and suggestions / OSTOC(Open source toaster oven controller)
Hi guys,



After seeing the part tester/transistor tester project i felt there is need for many opensource lab
equipments like the famous bus pirate,opensource logic sniffer and so on...

i got an idea of opensource toaster oven controller for many SMD soldering. yup there are many opensource
controllers but some are difficult to build or simply less info to build one yourself,i am really impressed
by arhi's soldering station controller almost similar to a oven controller but there is a need for a compact,opensource,specific,
easily hackable,easy to build like transistor tester project with minimal parts.so just an idea for someone to
build it,sorry guys i am not an geek but in serious hobby :-) just check the attached file n sorry for my english.
posting here in DP forums because i found oly site with serious electronics...

Below some suggested features:-

*all in one built around a case to protect against high voltages involved in input supply for oven.
*2*16 character lcd for temp readings.
*USB for datalogging and control from a pc.
*protected socket for oven power supply.
*no need to hack an oven just plug in power and install temperature sensor.
*opensouce software for soldering profile setting and temp monitoring.

if anyone interested can start a project around it..



Thanks

Project development, ideas, and suggestions / DIY ultrasonic range finder
Hi guys,

 i have been trying this project  low cost diy ultrasonic range finder i came across this (sorry guys i cant insert URL DPforum does not allow )
i want to build in house for my friends in a college starting a robotics projects but limited
money but have components from lab if anyone can help simplfy this would be really helpfull
and can the PIC chip replaced with an attiny?


thanks guys find the attachments below...
