The DIY Mini Digital Oscilloscope Kit (with shell) is an easy-to-build kit for a tiny digital oscilloscope. Besides the power switch, it has only one other control, a rotary encoder with a built-in pushbutton. The kit's microcontroller comes preprogrammed. The 0.96" OLED display has a resolution of 128 x 64 pixels. The oscilloscope features one channel that can measure signals up to 100 kHz. The maximum input voltage is 30 V, the minimum voltage is 0 V.
The kit consists of through-hole components (THT) are surface-mount devices (SMD). Therefore, assembling the kit means soldering SMD parts, which requires some soldering experience.

An illustrated chronicle of Teknology for collectors and restorers
Oscilloscopes have made a major contribution to the advancement of human knowledge, not only in electronics, but in all sciences, whenever a physical quantity can be converted into a timerelated electrical signal.
This book traces the history of a crucial instrument through many Tektronix products. This is the company that invented and patented most of the functions found in all oscilloscopes today. Tek is and will always be synonymous with the oscilloscope.
In nearly 600 pages, with hundreds of gorgeous photos, diagrams, anecdotes, and technical data, you'll travel through the history of Tektronix in a superb collector's edition with a technical point of view. The author is not afraid to get his hands dirty restoring his own Tek equipment. The journey starts in the early 1950s. It ends in the '90s, after exploring the ins and outs of the most interesting models in the 300, 400, 500, 5000, 7000, and 11000 series, from tubes to advanced hybrid technologies.

Understanding and Using Them Effectively
What happens in electronics is invisible to the naked eye. The instrument that allows to accurately visualize electrical signals, the one through which the effects of electronics become apparent to us, is the oscilloscope.
Alas, when one first ventures into electronics, it is often without an oscilloscope. And one is left fumbling, both physically and mentally. Observing an electrical signal on a screen for the first time is a revelation. Nobody wishes to forgo that marvel again. There is no turning back.
In electronics, if one wishes to progress with both enjoyment and understanding, an oscilloscope is essential. This marks the beginning of a period of questioning: how to choose one? And no sooner is that question answered than a whole string of others arises, which can be summed up in just one: how does one use the oscilloscope in such a way that what it displays truly reflects the reality of the signals?
Rémy Mallard is a passionate communicator with a gift for making complex technical subjects understandable and engaging. In this book, he provides clear answers to essential questions about using an oscilloscope and offers a wealth of guidance to help readers explore and understand the electrical signals behind electronic systems. With his accessible style and practical insights, this book is a valuable tool for anyone eager to deepen their understanding of electronics.

An Illustrated Handbook of Vintage ‘Scopes Repair and Preservation
Tektronix oscilloscopes are true masterpieces of electronics and have helped mankind advance in every field of science, wherever a physical phenomenon needed to be observed and studied. They helped man reach the moon, find the cause of plane crashes, and paved the way for thousands of other discoveries.
Restoring and collecting these oscilloscopes is an exciting activity; it is really worthwhile to save them from the effects of time and restore them to their original condition. Many parts are quite easy to find, and there are many Internet sites, groups, and videos that can help you. Much of the original documentation is still available, but it is not always sufficient. This book contains a lot of information, descriptions, suggestions, technical notes, photos and schematics that can be of great help to those who want to restore or simply repair these wonderful witnesses of one of the most beautiful eras in the history of technology.
Component layouts included!
This book includes a nearly complete component layout plan of the original 545 oscilloscope, with relative reference designators. Not found in the original Tektronix manuals, this layout should prove invaluable to the repair technician.

The MicroMod DIY Carrier Kit includes five M.2 connectors (4.2mm height), screws, and standoffs so that you can get all the special parts you may need to make your own carrier board. MicroMod uses the standard M.2 connector. This is the same connector found on modern motherboards and laptops. There are various locations for the plastic ‘key’ on the M.2 connector to prevent a user from inserting an incompatible device. The MicroMod standard uses the ‘E’ key and further modifies the M.2 standard by moving the mounting screw 4mm to the side. The ‘E’ key is fairly common so a user could insert an M.2 compatible Wifi module. Still, because the screw mount doesn’t align, the user would not secure an incompatible device into a MicroMod carrier board.
