Evolution EAA Computer Mount

Due to the horrible light pollution here in San Jose, CA I decided to try out EAA- Electronically Assisted Astronomy. Traditional astro photography (AP) is actually really hard and time consuming. EAA is a lot easier and lot faster, although the results aren’t as nice as you can get

ESP-DSC: Making it work

So my initial testing of an ESP-12E showed that it couldn’t reliably keep up with two 10K PPR encoders (40K count). I discussed this project a great deal with my fellow astronomers on CloudyNights. After doing a lot more research and testing I’ve determined that the ESP8266 even

ESP-DSC Works Not Well!

So yesterday I was all happy that I got my prototype ESP-DSC working. This ended up being short lived as I realized this morning that while it does technically work, the ESP8266 can’t keep up with two medium resolution (2,500 CPR) encoders. Ironically, I found out that the

ESP-DSC Works!

Spent most of my post-St. Patricks day writing code for the ESP-DSC. The big question was always does the ESP-12E have enough horsepower to handle both the encoders as well as doing all the WiFi/communications. So far, I’ve bench tested a pair of 2.5k CPR encoders which

New low cost digital setting circles: ESP-DSC

So a few years ago, I announced TeensyDSC, project that brings telescope digital setting circles to the iPad and Android devices using WiFi. I’ve been using my TeensyDSC successfully with my telescope and SkySafari on an iPad for a few years, but one thing always bothered me about it:

A working basic TeensyDSC board

I recently got my first generation PCB in the mail from OshPark and I’m happy to say that the board works just like I had planned! I was able to do some basic testing using 10,000 step encoders, but due to the power of the Teensy 3.1
