Listen to your favorite music using your iPhone, iPad, or Android device through the 3.5mm AUX audio input or using the built-in digital AM/FM radio with 20 station memory. Set two separate wake times with the dual alarm feature for you and your partner.You can also choose to automatically disable the alarms on weekends, allowing both of you to set your alarm schedule once! and forget it! Restores your alarm settings and automatically adjusts for daylight savings time. All you need to do is specify your time zone and it will always be accurate, even after a power outage. This smart alarm clock is preconfigured with the correct time. The adjustable focus allows the projected time to always remain crystal clear. This feature also allows you to tilt a full 180 degrees, so you can project the time or even the temperature. Find the time difference between several cities with the Time Difference Calculator. It will always be in full view from anywhere in the room even when you are lying in bed. This alarm clock also displays the indoor temperature (C/F) and the current day/month/year. If you need calculating time for some city that is not present in our. Note: We have more than 600 biggest cities of the world in our app, that cover ALL possible world time zones. Use the world clock to see the current time around the world. The dimmer options (high, low, off) let you reduce the screen’s brightness for those sensitive to light. Calculate exact time anywhere in the world across time zones. View the time/date & temperature clearly on the large 3.6” blue display. Plus, with time projection display, dual alarms, temperature display, a large backlit LCD with dimming options, and the ability to play your smartphone, tablet, or MP3 player music, this is the only alarm clock you’ll ever need. This advanced clock radio automatically sets the time and date and saves all your alarm settings when the power goes out. For help setting the time on your clock, visit this link to find the manual for your product: Manuals. or if you want, else use them to your advantage by modifying or examining their bits in their respective input and control registers &H379, &H37A.Convenience, reliability, & modern design come in the form of the EAAC601 Projection Alarm clock by Electrohome. There are several reasons your clock could be displaying the wrong time. You can forget about all the other control lines like *ACK, *Busy, *Strobe etc. Explore Ljubljanas sunrise and sunset, moonrise and moonset. Get Ljubljanas weather and area codes, time zone and DST. (Assumes parallel port LPT1 is the port available on your PC). Current local time in Slovenia Ljubljana. With PORTTALK22 and QBX QBASIC no fancy QBX code or amu other Windows configuration is necessary, you simply use simple commands like: OUT &H378, byte 'where byte is a 8-bit value byte=Inp(&H378) 'Hardware Port Address of LPT1: 8-bits of I/0 immediately available. PORTTALK22 also enables Microsoft Visual C and Visual Basic access to the Parallel Port. I also use the powerful, but super-legacy full-screen DOS "IDE", with the DOS Prompt compilable programming language QBX(QBASIC 4) to create quite complex programs that make use of the PC parallel port to communicate I/O easily with MCUs or any other hardware devices. Use PORTTALK22 and you get complete Parallel Port Input´Output control from Win XP. Can't you just use an optocoupler, like MIDI has always used and a transistor inverter circuit to convert the output of a serial port to something useable with 4xxx or 74xx ICs? This is of course ignoring the task of setting up software to do this, I'm just interested if it's possible hardware-wise. This got me thinking, Is it practical to use the serial port of a computer to send data to shift registers like that, or even old 4000 series stuff like BCD to 7seg ICs? I see that the RS232 ports on most PCs swing from -13V to +13 V and use negative voltages to represent 1 and positive for 0. Plus, with time projection display, dual alarms, temperature display, a large backlit LCD with dimming. I've never used a serial-in parallel-out shift register before (or any shift-register) but I see how it works. Convenience, reliability, & modern design come in the form of the EAAC601 Projection Alarm clock by Electrohome. I was looking at a 40 pin MM5451N LED Display Driver I got from an old General Instruments/Electrohome satellite receiver and from the datasheet I see it's basically just a 35bit shift register that can sink current from the cathodes of common anode 7 segment displays.
