outdoor/indoor humidity temperature and solar radiation sensors.Hacking the infrared codes gives you endless possibilities: Using a micro controller you can built an universal HVAC controller which can map the desired indoor temperatures and control all devices like air conditioning units, ceiling fans, heaters etc. In a modern house, most electronic devices are controlled by an infrared remote.

Important !! Last two commands are not implemented at the official Fujifilm remote control. "1" (pause ) duration is 1620us, "0" (pause) is 600us and signal (38KHZ) duration is 580us.Īfter last bit we have a pause of 40.6ms. Here is a video of the discharging sequence :įujifilm Finepix S2000hd infrared remote control hackĪt first a pulse of 9,2ms (of 38khz) must be send followed by a 4.48ms pause Night vision is enabled on TRV-22 because most of the process took place at night. Battery number 3 is the best because its charging begun 2h 45' after no's 8 and 9 (by examining the EXIF metadata in every pictures file). In the following time- lapse video you can see that batteries 8 and 9 are the first to begin charging (that means that are the first to discharge - the ones with the less energy) because their leds lite steadily first of all the others.

The fist discharged battery is the weakest and the last one has the maximum amount of energy.

When a cell is being discharged a red led flashes slowly and when discharging is over it lights steadily until full charge when it finally becomes green. TRV-22 can take photographs every 1, 5 or 10 minutes in memory stick (120 photos 640x480 resolution on 8MB memory stick) I fully charged the batteries and then discharged them, photographing the charger's leds every 10 minutes. I used my intelligent 10-cell charger and my Sony TRV-22 DVR in photo mode and its simple intervalometer. Well, I used a different - and faster approach. We could also program some kind of Processing script to display the results graphically on the computer.

It has 6 analog ports, so we can take a six battery holder, cut all inter-cell connections (they are connected in series), put a resistor in series with each cell (it we are keeping it simple - a current source would be much better) and measure and log the voltage as it drops through the resistor. Let's take my favorite Arduino for example. Using micro-controllers one can easily (!!!) make an intelligent rechargeable battery monitor in order to check if his NiMh or Nicads are in good condition. Set up as Alt/Az or Polar mount status and when typing #:GVF# it should respond with its identification string, including the word Autostar and a time and date (when that firmware version #:Qn#:Qs#:Qe#:Qw# Stop movement after above commandsįOCUS CONTROL - there isn't any focuser on the scope - we will talk about it later.Īfter reading the excellent info on I learn that : " when typing a single control-F on the terminal the Autostar should echo an "A" or "P" depending upon whether it's

A much more elegant solution to taping the cable is to duplicate the controling serial port using a serial to ip server, and open a teminal (like TeraTerm) at 9600N81 to view and log the traffic.After all my finds were :

A lot of info is written about Meade's serial protocol but the best way to learn about it (exactly as I did) is to tap the serial cable and spy on the data when controlling the telescope with a proper software such as Drsoft 's Meade control panel, Carte des Ciels or Stellarium. All you need is the optional 506 cable set from Meade which is actually an RS232 to I2C adapter that connects to the AUX port of the microscope. Barlows 3x lens was also used that deteriorated the resolution but I wanted to push it to its limits.įrom the point of view of an electronics engineer the most interesting feature of the ETX-90, is the precise guiding mechanism which can be controled by the computer's serial port. C, a sea area existed between the scope and the target and atmospheric conditions far from perfect. At this case the distance to the subject (the Mi-8 Helicopter) was about 2.5 kilometers, temperature was about 27 deg.

Even though the USB video adapter has a resolution of just 640 x 480 pixel, it is very good for land surveying as shown on the following video. When Lidl sold its Bresser microscope (another 60 Euros welll spend), it supplied it with a USB camera that fits not only to the microscope, but via an (supplied) adapter to the 1.25' eyepiece holder of the ETX-70. That telescope costed a mere 200 Euros at Lidl and in my opinion it isn't just a fine little telescope for the beginer, but it's also perfect for land surveing. These fine nights of September when Orion rises early the morning above the horizon, and Jupiter dominates the sky, its a pleasure to use the small ETX-70 telescope guided by its Autostar 494 controller.
