Note: I am no longer selling these scopes and kits.
No plans to resume selling them either.

Ever wanted to have your very own oscilloscope for your hobby or schools projects,
but didn't have the money and/or space for one?

Ever wanted to provide each student in your class an oscilloscope of his/her own?

Ever wanted to build your own test instruments?

Many people who do electronics as a hobby or in education (where funds are notoriously tight) don't need
a super-high-end instrument but rather want something that is very affordable yet highly usable in practice.

DPScope II - our brand-new, top-of-the-line model (comes fully assembled)
DPScope - the classic, now still available as a self-assembly kit
DPScope SE - entry-level kit geared towards education

The oscilloscopes on offer here are just that - simple to use, yet have a full feature set like you find on
professional instruments. They are all PC based so you get to use the processing power and the large
display of modern computers. They are a great introduction into this area, and are designed to be of real
use in practical applications - after all, scopes are a big part of my day time job as well, so I think I have a
pretty good grasp of what is important and what is not.

Scopes and other test equipment are my passion, and I am always glad to hear about new uses for the
instruments I design. Also if you have any questions related about oscilloscopes feel free to
contact me.

I make a point of putting the full circuit schematics along with description online (along with description of
the circuit design), similar to how Tektronix did it in the "old days" (though I would never dare to compare
my little creations with Tek's works of engineering brilliance!). That way every user can really understand
how the hardware works and get a better idea what the instruments do "under the hood".

For questions, suggestions, feedback etc. please do not hesitate to
contact me.
What is this site about?

The oscilloscopes shown on this website are not intended for high voltage applications. Use proper
precautions when working with high voltages (anything exceeding 20V peak).
You do so at your own risk and
we cannot be held responsible for damage to life or property resulting from such work. Attempt such work ONLY if
you have the necessary knowledge and training. Observe all required and recommended safety guidelines. Make
sure the probes are set up to the required division ratio before probing. Never apply any voltage exceeding 24V to
the oscilloscope inputs. Note that the peak value of an sinusoidal AC signal is approx. 40% higher than its rated
effective value.

The author of these pages does not assume any responsibility whatsoever regarding the design, construction or
use of the described circuits and instruments. The author cannot be held responsible for any damage to persons
or property connected with the described designs. This includes (but is not limited to) damage to you or your
computer, fitness for a specific task, and specified performance. If you decide to build the oscilloscopes or use
them, you do so at your own risk. Observe safety guidelines when soldering and when working with electricity.
Never apply any voltage exceeding 20V to the oscilloscope inputs.
