The DC-DC converters are effectively a small switching power supply.? Back in the day Meade supplied a small DC-DV boost converter when the LX200 called out 18vdc.? The AC power supply was

West Mountain Radio sells battery boxes that can be customized with various switches and meters. You might find something useful there. I believe they also offer batteries but please don’t hold my

Glenn, Excellent, thank you! I was eyeing that converter but had not seen the battery box. And the battery is on sale! -Mario

I’m using a DIY custom battery box from Amazon with a 12v 100ah LifePo. ?You can run a 12-19v step-up. <img src="https://i.ibb.co/sJ1JFWq/IMG-4667.jpg" alt="IMG-4667" border="0"> <img

Chip, Thanks — this looks like a great approach. Was there a particular brand of DC-DC converter you used? -Mario

I went the DIY route several years ago with a $15 heavy duty Craftsman tool box loaded up with a 28ah AGM battery, a smart charger that allowed the battery to supply power while plugged into utility

Thanks for the reply. The reason I ask is that when I first got my G11 (20 years ago!) the goto performance of the servos using 12V was awful -- many stalls. 18V fixed that. So I want either (a) a

Depends on what power bank you get. I got a bluetti type a while ago to deal with frequent power outages at home and have yet to try it with my mount. Those types come with AC outlets, 12V car lighter

Is anyone using a Lithium portable power bank for a G11-Gemini1? If so, are you providing 18V as well as 12V and if so, how?

Thanks Brendan, ...I had actually seen this useful page when I searched.....but the appearance of -5v as well as +5v on another pin made me think mine might not be like the one in the diagram for some

Oh one thing. I ment that you may need to lower data out rate to 4800 bps as most are 9600bps. Usually easiest to do this with USB or USB/Rs242 converter and terminal program like terraterm. There

Hi Brendan Thanks for the info. The GPS is a Globalsat BR305. By examining the USB adapter it came with, I managed to determine which pin on the PS2 connector is +5v. Strangely(I thought) there is -5v

Without knowing the GPS unit no one can tell. I mean it could use +/-12v rs232 not 5V or even 3V. Though I doubt it. It might have a buffer IC driver which protects things like cross connection If it

Hi There, I'm replacing my GPS unit because the old one suffers from the GPS rollover issue. However, the PS2 connector is wired differently on my replacement unit, but I still wish to use the 4 pin

Good evening, Have you sold your Gemini 2? Is the hand controller included? I may be interested. Mark Whittier, CA

Years ago I published this document about making a Gemini GPS from an inexpensive GPS module. ?My unit is still in operation on my Gemini 1 after all this time. ?Hope it helps. - Bill

I've miss connected Rx/Tx ...it shouldn't cause any problems.? But that was different chipsets!?? You can use the mini USB and import GPS data thru Gemini ASCOM...FWIW Cheers -- Brendan

Thanks. I had the power pins down. It was the Tx and Rx pins I was not sure of. I know I have a fifty fifty chance of getting it right. But like I always say a fifty fifty chance of being right means
