It sounds like you have an incorrect serial port referenced... so it is attempting to send the commands, but not to the correct location. If you are using BASCOM, then try looking for information on the BASCOM forum.http://www.mcselec.com/index2.php?option=com_forum&Itemid=59
Hello. I'm new in programming. I used a sketch I got from an instructable that used BASCOM. I always seem to have this error when I click the program button:stk500_2_ReceiveMessage(): timeout:-1and ser_send: port not open or ser_read: port not openI'm using Arduino Uno r3 (328) and WIndows 10. Hope you can help. Thanks.
Yup... drip only... the PVC is not pressurized, with holes drilled in it at regular intervals... strings carry the water to the ground. I don't live there anymore... but it has been in continuous use since about 2001 or so. (I think that's when I built it... LONG time ago,)
HVAC condensate is an excellent source of relatively clean, chemical free water for non potable use. However, I caution you against spraying the water. It is possible for the water to pick up microorganisms when it comes in contact with the AC coil. Legionella is a particular threat. Spraying the water can release these into the air where they can be breathed in. If used for irrigation, the water should be used in a subsurface or drip system.
Perfect timing... I need to get my car inspected this week... so tomorow... off to the auromotive store.

You may want to look at the Tiny-26 processor which has 4K of memory. I have been using BASCOM for decades as my compiler of choice... I have an instructable on that as well. MY BASCOM INSTRUCTABLE (The demo / free version goes to 4K) If you are not limited to 4K of memory, try the Mega-328 chip which has 32K of memory. Have fun... it is very interesting to work with microprocessors!Jerry
Please be careful .that water has high amounts of lead in it.if your teeth are turning black your poisening yourself.a test kit and fiktering may help but be dilligent and careful it may be building up in you
Ok... I'm an electronic tech (CET), I've been doing computer in one form or another since 1978, and I'm a bit of an all-around geek. Never heard of a switch tester before today. Seriously. So I researched... and found out they were for testing the feel of the Cherry MX type switches... I saw a whole bunch of different colors and thought, "What's up with that?"So... I finally found out about the differences: CHERRY MX SWITCH TYPES.Now I got it... and I've learned something for when I go looking for switches in projects... so thanks for that! Overall... great instructable! I like the ability to hit one key and have it type some text. Could be useful for other things like frequently typed commands, logon names, or similar things.
This is probably the most professional Instructable I have ever seen. Your photography is excellent, the text is well thought out, and everything is very well organized. The project its-self is great too. Outstanding job overall!
Hypertufa is a great material to work with... you can be very creative in your design.
Sandblasting works very nicely for rock and/or concrete. My wife has done sandblasting in different materials... and it comes out very nice. While the masking material is still in place, spray paint a contrasting color into the marks. When the masking is removed, it comes out very nice. Likely there are places that do sandblasting nearby and it should not be overly expensive.
Thank you for the tutorial. It is very helpful for a newbie to sandblasting. I didn't see the length or size of air hoses you used for the foot pedal...I assume they are 3/8"? What length did you use & did you also buy them at Lowe's or similar DIY store? Thanks!
Thanks Jerry. Just one more question- what is the minimum size air compressor needed for this system? Do you recommend any particular compressor?
