Turisar Even though the Sceptre offers lots of peripherals, it only has fifty pins, which means that certain functions are obliged to share pins. Thank you Thank you so much, it was a fantastic job. Some of the projects are almost unbuildable. The other diodes D2, D5, and the other D2 uuni the Sceptre take care of the rest. We opted for male connectors to ensure compatibility with PC serial ports.

Bragrel If unity gain is all you need, you can omit these and connect the inverting inputs directly to the outputs. Power supply and battery During application development, the Sceptre will be connected to a computer via a USB cable connected either directly to the Sceptre, or via the InterSceptre.
But the information and the descriptions of the circuits and how they function are a very practical way to see the real world of electronics after learning from the textbooks. Each of the signals leektor protected by a small current-limiting resistor.
This can be handy where the Sceptre is being powered from a battery. Thank you Thank you so much, it was a fantastic job. Elektor Magazine Item Preview. Even though ele,tor Sceptre offers lots of peripherals, it only has fifty pins, which means that certain functions are obliged to share pins.
As already mentioned above, the InterSceptre itself does not produce the 3. The Internet module is powered from 3. Treasure trove of electronics information I first dipped my toes into electronics engineering via Elektor and I have profited greatly from it over the years. The chip itself adds the missing four MSBs, hence its address is xxx, where xxx represents the position of the three switches 0x20 to 0x27 in hex.
This IC is compatible with 3. Well, quite a lot, actually: So take care how you fit the regulator! I collected Elektor for nearly 20 years but sadly I had to give them away due to space limitations. For applications where no USB connection is possible or necessary, or if more power is needed than can be supplied by a USB port, a 5 V supply is available via the InterSceptre. Note to that InterSceptre does not offer a 3. The InterSceptre extension board circuit diagram is available in the downloads below.
The MIDI port consists of just an input and an output. Now I can access them again on-line — how good is that? Elektot minor drawback with the Sceptre is the absence of the battery voltage on the extension connectors — but it does have its own battery. Like the Sceptre, InterSceptre is also an open-source, open hardware project. Paulo Morgado — favorite favorite favorite favorite favorite — February 27, Subject: We have made provision for two possible regulator types a or a low-voltage-drop stylewhich, for some unknown reason, do not have the same pin-outs.
One issue I did retain for posterity was Elektor Book 75 which I could not locate in the English archive listing https: Given that the InterSceptre can operate from 3. You can connect a switch to JP9 to let you turn off the Sceptre power. The gain is adjusted using turn presets.
In this situation, the USB port can provide all the power. Given the number of ports implemented, the circuit is pretty huge, but easy enough to follow. Detailed description The InterSceptre extension board circuit diagram is available in the downloads below. For microcontrollers with more UARTs, the ports are available elektof them.
This terminal strip is opposite a little area with mounting holes where you fit a few components to create interface you need. In this way, InterSceptre has four analogue outputs, available on the way sub-D connector K Follow project Add a comment. Note that it is highly inadvisable to hot connect or disconnect equipment to this port.
The InterSceptre PCB has been designed to fit into a case which, in addition to providing protection, also lets you use the unit directly within a final application without its looking like a bodge.
The InterSceptre operates from 3. In any case, there are very few applications that would require everything to be used at once. Thanks for the effort it took to get this all together. The shells fix together using a pair of screws. The other diodes D2, D5, and the other D2 in the Sceptre take care of the rest. I lost most of my collection to water damage when I last moved so this is so appreciated.
Not all of the information is current. One important detail not to be overlooked: Related Posts
