This is example how to interfacing Nokia 3510i LCD to a Microchip PIC16F84.Both LCD supply pins are tied to the output, which is around 3.0V. the connections are made by soldering standard IDC ribbon cable directly to the glass substrate.All four signal lines have 10K resistors in series, to protect the LCD inputs from the 5V signalling of the PIC.[more]

This is a bench power supply with regulated DC outputs -12V, -15V, +5V, +12V, +15V, and variable and one +35VDC unregulated output. This bench supply almost exclusively upon Andrew Kilpatrick’s design. [more]

If you want to interface an LCD panel read this article wrote by Andrew Wiens.He build from a vintage 486 Compaq Contura 420cx to the VGA port at 640×480 resolution with 3 bits of color (one bit per color — RGB) for the purpose of displaying data from his upcoming ENSURE-2 near-space project.

The major disadvantages of usual linear power supplies are high power dissipation, the size and the appropriated weight. When looking for an alternative solution and the result of designed is a switch mode power supply (SMPS). The efficiency of such power supplies is around 70 % to 90 % at a power density of 0.2 W / cm³. Because homebrewing was out of the question due to lack of time[more]
