Diode–transistor logic (DTL) is a class of digital circuits that is the direct ancestor of transistor–transistor logic. It is called so because the logic gating function (e.g., AND) is performed by a diode network and the amplifying function is performed by a transistor (in contrast with RTL and TTL).
The DTL circuit shown in the picture consists of three stages: an input diode logic stage (D1, D2 and R1), an intermediate level shifting stage (R3, R4 and V−) and an output common-emitter amplifier stage (Q1 and R2). If both inputs A and B are high (logic 1; near V+), then the diodes D1 and D2 are reverse biased. Resistors R1 and R3 will then supply enough current to turn on Q1 (drive Q1 into saturation) and also supply the current needed by R4. There will be a small positive voltage on the base of Q1 (VBE about 0.3 V for germanium and 0.6 V for silicon transistors). The turned on transistor's collector current will then pull the output Q low (logic 0; VCE(sat) usually less than 1 volt). If either or both inputs is low, then one of the input diodes conducts and pulls the voltage at the anodes to a value less than about 2 volts. R3 and R4 then act as a voltage divider that makes Q1's base voltage negative and consequently turns off Q1. Q1's collector current will be essentially zero, so R2 will pull the output voltage Q high (logic 1; near V+).

In this video, I discuss DTL family, its features and disadvantages.
A few shots from the 2015 Krieghoff DTL. A short video taken from the shoot to give you a flavor of this year's shooting. Thank you to everyone who came this year and for your continued support, plus a big thank you to our co-sponsors Hull Cartridge. We had a fantastic time. Congratulations to Ian Mullarkey on winning the title for the 2nd successive year and the 3rd time overall.
The Krieghoff DTL 2014. Held at Mid-Wales Shooting Centre over the 22nd - 25th May weekend where Ian Mullarkey took the title after a shoot-off with reigning champion Richard Greenlaw. For 2015 shoot date & information please visit http://www.krieghoff.co.uk.

14.11.09 Been lucky this week, 3 days of cross-off Lyall Bay! This is on one of the later days with the monster groundswell still around. More wind today. Some footage I took of the early birds before my session. Enjoy. Music is Shooting Stars by Bag Raiders.

A film by Davide Calafa telling the story from David Trubridge's 'Dream Space' installation at the Milan furniture fair in Italy. Dream Space features a large dome that acts as an internal ‘break-out’ space for quiet contemplation, an external gazebo as a garden sanctuary, or a light-weight frame for an attractive shelter. Seed System by David Trubridge is also a major part of this installation.
This is a hyperlapse of the 70-year flood in Calgary Alberta. It is a 170 frame hand-held shot taken while balancing on the concrete median. Step by step, the camera was centred on Calgary Tower while zoom was incrementally reversed so the Calgary skyline would appear to shrink away to reveal the magnitude of the flooding. This was a once in a lifetime shot, and may be the first hyperlapse shot in natural disaster.
The 2nd Seminar “Developing New Literacies In Cross-Cultural Contexts” was held at the University of São Paulo, Brasil, from September 14-17, 2010. blog do Projeto Nacional de Formação de Professores, Educação Crítica, Novos Letramentos http://projetonovosletramentos.blogspot.com/2010/07/ii-seminar-developing-new-literacies-in.html There are three debates framing work in English language and critical literacy teaching today that are important for the national project and to which our project can contribute. These debates are occurring within specialized disciplinary and interdisciplinary contexts and within the public sphere, fanned by politicians, the media, and concerned citizens. They are 1. debates within globalization and education studies about the nature and purpose of knowledge...
Underneath her skin and jewelry,
hidden in her words and eyes
is a wall that's cold and ugly
and she's scared as hell.
Trembling at the thought of feeling.
Wide awake and keeping distance.
Nothing seems to penetrate her.
She's scared as hell.
I am frightened to.
Wide awake
and keeping distance from my soul.
