He was at home, surrounded by family and loved ones. Roddy passed away on Sunday, December 5th, 2021. It is with the greatest and most profound sadness that I write to inform our community of the passing of Gerard (Roddy) Creedon. To honor the contributions to the study of the built environment of Paul Groth, professor emeritus of geography and architecture at the University of California, Berkeley - and mentor to several of PLATFORM’s editors and authors - PLATFORM has organized a News - DecemIn Memoriam: Gerard “Roddy” Creedon (Nov. Downey, AIA will serve as the inaugural Lifchez Professor of Practice in Social JusticeĪn architect of universal design who specializes in spaces for blind and low-vision individuals, Downey brings decades of experience to teaching students justice, advocacy and accessibility as it relates to the built environment.

The American Institute of Architecture Students (AIAS) announced Monica Lamela Blazquez (MS.Arch 21’) as one of the winners of the 2021 AIAS Honor Awards for her thesis “Rave Assemblages: Itineraries of Leisure in Post-Franco Spain." News - Febru2022-2023 Branner, Stump, & Beckerman Fellows Announced You can vary the pulse width from minimum to maximum by changing the bit pattern at the DAC’s input from 00 to FF.News - FebruMonica Lamela Blazquez (MS.Arch 21’) Receives Prestigious AIAS Research Honor Award The maximum on-time of the one-shot is a function of the R and C values. You can send the required 8-bit word to the DAC via a PC’s parallel port or from a µP or ♜. The 8-bit DAC, with its MC 3104 op-amp buffer, provides programmable control of the one-shot’s pulse width. In other words, by selecting the voltage on this pin, you can control the pulse width of the output waveform of the timer. The control voltage on Pin 5 of the 555 can change the threshold of the comparator in the timer IC, thereby changing the on-time of the one-shot’s output. The timer IC is connected in a one-shot configuration with an on-time transfer function of t=1.1 RC.

The design uses a low-cost NE555 timer and an 8-bit AD7524 D/A converter.įigure 1 An 8-bit code applied to the DAC determines the on-time of this one-shot circuit. You can interface the programmable one-shot design in Figure 1 with any intelligent system, such as a PC, a µP, or a ♜. One-shot circuits are popular choices for the on/off control circuitry. More and more, the Internet is playing a role in control operations in industrial and R&D endeavors and in household appliances.
