Precautions Never work on a live circuit! Please post back with your results. Any other locations where the prog can be found? November 12, Update Several good, inexpensive, purpose-built USB to serial modules are now available on eBay for around five to six dollars. When attempting to program, the DTR pin does go low, but it stays low, keeping the Arduino in reset instead of actually resetting the Arduino. But HyperTerminal is also very nice, but not free.

December 19, at 1: Make sure none of the other wires are touching one another! Views Read View source View history. Any chance you could send the driver to me or post it somewhere? Does any one have an idea if there is a cble cable that uses 5V for the Rx and Tx pins?
Ex-Link Cable for C/D/E Series and BD players
One is for audio and the other is for “service”. They are really cheap and if you have the oportunity to order more than one at once, I suggest you to do it because this cables are really useful for lots of projects. It is only the Serial drivers which may look for a feed from the phone end, depending on which clone cable you have got.
If you release the button too soon the bootloader will timeout before the vku gets a chance to be uploaded and you will get an error. Newer Topic Older Topic. I love big hard drives…dig around enough and you can find the cruft of ages.
Thanks for sharing how to do it. November 12, Press several keys on the keyboard. Guys By far the cheapest way to make a USB to Serial cable is to buy in the cheapest USB mobile phone data cable that will do the job and crop off the phone end. If you want to power your board from the Host you need Vcc whatever Vcc is for your board ie 5v or 3.
How Can you Make a USB to TTL cable for Sanguino?
The 10k and 15k resistors on the Tx pin form a voltage divider to reduce the 5V output to 3. The CA was not available from anywhere at the local market went to 4 stall holders and only one had cagle DKU Outside of that it is only a couple of capacitors to ground and two series resistor to Txd and Rxd.
Studying a picture on your computer beats the hell out of using the magnifer on a Helping Hands. SO are not suitable.
November 28, at What cabel worked for me was to fill the via with solder, tin the wire, then place the wire over the via and the iron directly on the wire. You could try it and see, but you might smoke it. It was a bit of a headache.
I’ve had good luck with this Co. Larry Pfeffer, My blog about building repstrap Cerberus: But it’s out of the specification Necessity hopefully becomes the absentee parent of successfully invented children. I picked up 2 DKU-5 Nokia Data Cable Clones and they gave the following results after testing using dmesg on linux, with no phone connected.
IDEAS: USB-UART console using old nokia DKU-5 datacable. (v TTL)
This may or may not cause a timing problem when uploading. Hi, I got here via hackaday too, although the comments say that this has been done before your article has introduced me and doubtlessly others to this technique and I think its a great tutorial.
Serual need a bluetooth module for this job.
