If SDA is at 3. We opted for male connectors to ensure compatibility with PC serial ports. Like the Sceptre, InterSceptre is also an open-source, open hardware project.

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 elsktor final application without its looking like a bodge.

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. The level shifter used comes from a Philips or NXP application note. Each of the signals is eoektor by a small current-limiting resistor.

Some of the projects are almost unbuildable. Given the number of ports implemented, the circuit is pretty huge, but easy enough to follow. Thanks for the effort it took to get this all together.


I collected Elektor for nearly 20 years but sadly I had to give them away due to space limitations. This terminal strip is opposite a little area with mounting holes where you can fit a few components to create an interface you need.

Now I can access them again on-line – how good junl that? One issue I did retain for posterity was Elektor Book 75 which I could not locate in the English archive eleltor https: An important addition to the Archive An important addition to the Archive. Given that the InterSceptre can operate from 3. Framan – favorite favorite favorite favorite eelektor – September 9, Subject: This can be handy where the Sceptre is being powered from a battery.

In any case, there are very few applications that would require everything to be used at once.

In this way, InterSceptre has four analogue outputs, available on the way sub-D connector K Well, quite a lot, actually: 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.

The shells fix together using a pair of screws. The gain is adjusted using turn presets.


The MIDI port consists of just an input and an output. The InterSceptre extension board circuit diagram is available in the downloads below.


For microcontrollers with more UARTs, the ports are available to them. 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.

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.

If unity gain is all you need, you can omit these and connect the inverting inputs directly to the outputs. Advanced embedding details, examples, and help! So what has InterSceptre got to offer?

For software please refer to the Sceptre page. In this way, it is possible to connect a 3.

Search the history of over billion web pages on the Internet. Topics ElektorMagazineCollection. Treasure trove of electronics information I first dipped my muni into electronics engineering via Elektor and I have profited greatly from it over the years. You can connect a switch to JP9 to let you turn off the Sceptre power. Note that it is highly inadvisable to hot connect or disconnect equipment to this port.
