Yep, you get what you pay for. I think Futurlec is actually based in Australia but a fab shop is in Thailand. Either way, poor service, the product is decent. I got AVR boards and schematic was wrong. Had to waste a week with them in an attempt to get the Protel file so we can edit the changes and c...

Nibble Mode of parallel port? How to initiate a transfer
Does anyone have experience with nibble mode on parallel ports? http://www.fapo.com/graphics/nibfig1.gif From reading the doc I see that the PC actually has to pull the device meaning there is NO WAY for the device to initiate transfer to the PC unless the PC is pulling the device all the time? My r...

I got a board some time ago for $99 from a Chinese company on eBay. The board looked cool and I could not resist the price. Development was via Quartus (this was an Altera Cyclone 2 FPGA) and that is easy but the product of your hours of hard work is not comparable to what a Parallax board, for exam...

In an article this month Servo revews the uDrive mini SD logger. The specific device was reffered to as The uDRIVE-uSD-G1. It seems to be a cute board made by an Australian comapny - 4D systems: http://www.dontronics-shop.com/files/d_954.jpg I looked at the spec and it seems pretty easy to read/writ...

There are cheap 7 segment LED boards on eBay from some Chinese place. The board has 4 digits and you can dasiy-chain the boards for as long as 16 boards I think (that is 4*16 total lenght) All drivers and memory is integrated, you just shift digits via TTL interface, SPI-like with clock and data. Ve...

Try to find a generic modem program with an autodetect modem function. Even if the program cannot use your modem, it may be able to find it. Still no go but I figured why not call the modem and see if it will send RING to the serial interface. Well it does but I can't make much of it. Here is the w...

Check your COM ports using device manager to make sure they are OK first. After that the modem might be dead. Check its serial connector for damage, maybe look inside for solder joint failure at the serial connector or just check with DMM for continuity. Is the SIM card properly installed, Not clea...

Wavecom GSM modem WMOD2A-G1900 WM11725 series WMOD2
Hello, Does anyone have experience with WMOD2A-G1900 WM11725 Wavecom modem? How does one reset the modem to factory defaults. The reset pin DOES NOT do that. It simply executes power-on reset which is no different than powering OFF and then powering back ON. Unfortunately that procedure does NOT res...
