Piddler (Project by Markus Dohr and Bernhard Heine, HTL)

hello everyone!

First of all: Maybe the word Piddler puts up the question, what is that?
If you want to know look at the following page 🙂

Here is a short list, which contains the tasks of the school- project “Piddler” :
(adapters: Dohr Markus, Heine Bernhard)

1. The main task is to build a stroboscope. This will be realized by programming a microcontroller (with C),
which actuates LEDs.
Besides the frequency should be displayed on an LCD.
The flash power and the frequency will be varied with a potentiometer.

2. Another important task is the ciruit design. According to point 1 we are trying to
work with a 24V power-supply (and an additional power-supply for the necessary pumps).
This means that there are no special safety measures to consider.

3. Construction: for the frame we are using defined tread elements from the company Bosch.

4. Two pumps are designated, which are in charge of the watercircuit.

All this should happen in the following weeks. We have planned to finish the work at the project in the first week of March.

Programming: 15th of January
circuit design: 30th of January
Construction: 15th of February
Assembly: till March

best wishes,
Markus Dohr

  1. The expression high speed film gives the wrong impression. You only need high speed film when there is very little light available. With enough light a high speed photograph can be taken on slow film (small ASA number). High ASA numbers (high speed film) is only needed when light levels are low.

    Single flash strobe is also a strange combination of terms. A single electronic flash works better for me. The word strobe originally meant to do with seeing. It has unfortunately become a word describing electronic flash. My father finallt gave up and used it that way himself in his book Electronic Flash, Strobe.

  2. Hi Bob! Good to hear from you. Where did you catch the phrase high speed film in the HTL students article?

    Thanks again for the strobe clarification, people outside of the field usually dont know this. Your father mentions the correct explanation once in the lecture videos (also viewable from the interactive DVD) from MIT.
