Return of the Jedi

Freezing cold

A pair of surface heating plates, dew heater band, temperature sensors, humidity sensors and three Arduinos kept this equipment up and running.

Penguin goes space

New needs in image processing are met with this powerlaptop installed with Mint Linux.

16 GB of RAM and almost 10 TB of hard disk space:

Filter offsets made easy

This little program which I wrote a couple of months ago automatically calculates filter offsets for your filters. Very useful and a real timesaver.

Photometric UBVRI-filters are being measured:

Sometimes focusing fails and that's where the cumulative average comes in:

DS Buster

DS Buster is DIY dew heater controller based on Arduino UNO microcontroller, DS18B20 temperature sensors and 4-channel MOSFET PCB driven by PWM. In manual mode one can control output power of each four channels (P1-P4) separately. In automatic mode output power is controlled based on temperature sensor readings (still ongoing project).

Problem solver

I favor EXSYS and StarTech industrial grade powered hubs with external power exclusively. EXSYS operation mode defaults to that but in case of StarTech you have to open the case and remove one jumper on PCB.
