Have to say, drag soldering is an amazingly effective technique. The few SMD chips I replaced previously were always a struggle, and I tried solder paste and soldering individual pins. Drag soldering

It’s actually not *that* hard using a drag soldering tip (the ones that have a concave end to hold some solder). I’ve done it myself a few times, and only needed to do a bit of cleanup with solder

I draw the line at 20-30 pin packages. Don't even want to think about replacing a 128 pin ARM chip :)

Yeah Paul has been doing his hand at some G2 ICs R&R and is doing well (another notch in his belt of skills)! David partridge, Michael and I and even others, Losmandy!. ?Many electronic repair places

For a skilled small electronics person SMD repairs are not a big deal. But you 100% need a good SMD rework station and some reflow materials to put them back together.? There are also some health and

David Partridge, in the UK can also do PCB repair work.

Fritz, Glad you got it worked out though you had to buy the replacement. The PCB components are machine soldered at the manufacturer and are extremely difficult to remove and replace by most people.

Alright, thought I’d close this out. New board installed and zero issue now with the mount. Swings the RC10 around easily and guiding last night seemed to be alright (bit of clouds and only initial

Hi Folks, An official new version of Gemini firmware Level 6.1 and Hand Controller firmware v1.63 are now available for your Gemini. A few ways to update to this version: 1. Use GFU app (

Thanks for that? Aliexpress link. I have ordered it. Roger

Hi Roger, Astro-Gadget sells a couple of these cables ( https://astro-gadget.net/gadgets/cables/losmandy-gemini-2-rj9-usb-pc-cable-7m ). The link gets you their 7m version for Gemini 2, but they also

That's worked great for me, reliably (running gemini 1 from mini PC). Bought 2, just in case chip dies out. https://a.aliexpress.com/_Ev6jse1

Hi Paul, Thank you for your clear response. Yes I am surprised to find so many cables with so many different pinouts. I am hoping someone who went through this process can make it less painful and

Ah, I see. You'll need an FTDI-based USB to RS232 adapter, usually with a 9 pin DB9 connector, such as this ( https://www.amazon.com/OIKWAN-Converter-Adapter-Chipset-Windows/dp/B08Q86PFV1 ). Then,

Hi Paul, I have not bought any FTDI or the cables.? That is why I am asking. Thanks, Roger

Hi Roger, what connector is at the output of your FTDI converter? Maybe share the model # so we can look it up.

Hi, I am requesting links to sources for the cable for connecting the Gemini2 serial port to USB with FTDI. I don't mind connecting 2 cables together to make one, but it is difficult to know which

Hi Wayback, Thank you for the good advice. I connected the Gemini2 USB to my laptop. Device Manager did not make any change. I tried with 2 different cables. So my conclusion is the Gemini2 must have
