A new installment on my long-running telescope project is provided here.
An Arduino MEGA2560 is combined with a GPS receiver and additional support electronics to slave an old-style pendulum clock to GPS.
One of my clients had need for a small 3-axis fixed positioner and nothing could be found on the market to serve the needs in the time frame needed. Based upon my telescope work, I cranked out two 3-axis positioners. The fixed positioner was completed whereas the computer-controlled positioner is still in work and more a side project of my own more than anything else.
I’ve been rather slow in up-loading the last installment of my photogrammetry project. The write-up can be found here. This segment is largely focused on optical encoders and related topics.
Part III of my Photogrammetry project has just been uploaded to the site.
