Does anyone have experience using an ARTS-2 with M-Tek matches, and in single battery mode? I've used the 2-battery setup just fine, but wondering what others have tried in single-bat mode?
I saw this battery on Sparkfun. 2x power capacity over standard or NiMH versions. Max current of LiPoly is at least 2C, so this battery should be able to put out 1A short term.
I've had dozens of successful dual deployment flights with ARTS-2/M-Tek/Single Battery conbination. Just follow these two rules:
- Configure the ARTS-2 in two battery mode (to defeat the current limiter), then wire the +9v from the battery to both positive terminals on the ARTS. A single ground connection to the negative battery terminal is sufficient.
- Use a fresh (and tested) battery for each flight. A fresh battery should test out to at least 9.3 volts. Remember one battery; one flight.
I also exclusively use Duracell batteries.
Yep....a 9 year old thread....Hopefully this might help other ARTS user
I like the ARTS(2) altimeters. I use them mostly for "student" projects. At this past LDRS at TCC I had a group of students coming out to fly their STEM projects. I wanted to test fly the altimeters prior to using them in the students projects. I have a rocket that I use to test altimeters or GPS trackers in. I did two test flights and could not get either of the two ARTS2 units to fire it's charges. I was using a single battery like I always do. Yep it was a fresh battery and my normal matches. I did one more flight with two brand new ARTS2 units and neither of them fired either.
This past weekend I went out and flew them again. Two flights with 2 different units. Still nothing. Came home and played around with them. I could not get any of my ARTS to fire any charges in either the one battery or Two battery configuration via the "DataAnalyzer" program - Altimeter- Diagnostic.
I found this thread the other night and last night and gave it a try. It worked!
In the photos..
Hook up a "good" single battery to -Bat+
remove the "1Bat" jumper
add a switch (grey wires in photos)
the 'new bypass wire' is the red wire with the black stripe. It goes from the Bat+ to the Pbat+

You may notice the 300mah Lipo. I wanted to find out what was not a "good" battery. That battery was used in 2 dual deployment flights on Saturday. It's at 8.04v and seems to work just as well as the 'good" 9v battery I was doing most of the testing with.
I have not test flown this configuration yet! I'll report back once I do.
FredT - thanks for posting the above. I was pulling out the little hair I had left. I was close to get rid of all the ARTS I have. Hopefully my test flights go well too.
Thanks for tip!
I think I'm just going to go 'complete old school' and use a 9V
By the way...awesome flight awhile back!
For some reason if you don't use an XP machine; you get weirdo Chinese styled characters in the Notes section where your good flight info was under XP.Cheers Tony! Means a lot coming from you.
Old School....feels like just the other day these things were state of the art!
Btw, JD I feel you on the computer issues. After years of battling away, plugging things in at a certain time, holding my tongue the right way....I gave up and now just have an old dinosaur PC running XP set up just for these.
Old School! Using 2 batteries with the ARTS2 was really a pain. Now that we have the single battery solution so clearly defined (I really like the LIPO) I wonder if I can get my old ARTS2s back. But I can't remember who I gave them to. Anyone know?
Whats the stick for?
I have an ARTS2 and the GPS module. I've been considering offering both up for sale. Since there appears to be still quite a following, is there a market for them used?
