Radio Shack may be history, but there are still outfits selling simple and cheap kits. If you’re a radio ham or interested in becoming one, check out QRP Labs:
Como NeoTeo nunca descansa, te invitamos a ti a tratar de hacer funcionar algún elemento que esté preparado para ser alimentado por otras fuentes de energías, con tan sólo tres baterías doble A. Ya que el MC34063A comienza a ser eficazmente operativo a partir de los 4V, creemos que con baterías frescas y una tensión de entrada de 4,5Volts podemos lograr interesantes salidas de tensión y aplicarlas a diversos circuitos y/o equipos.
The point I really wanted to get across is to be cautious when considering rules of thumb type advice. Question the sources of information, and do not be afraid to measure for yourself what you can when you can if in doubt. Above all else ask the question, “How do you know?”.
It turned out Caddock, Vishay and others could supply resistors with very high voltage ratings OR with low TC, but not at the same time, at least not in this extreme form. (They do offer extremely impressive components, though.) After considering quite a number of alternatives, the designers settled for a series of 60 resistors of a low-TC type with a reasonably high voltage rating (hundreds of volts). The cost was 30 EUR per resistor. To achieve the overall voltage rating a zig-zag layout had to be used, so adjacent pins (after one zig-zag) are at most 500 V apart. It took the technician two days for the soldering. He took his time to make sure each solder joint would be perfect, and quickly soldered. The whole thing had to be potted for safety. It got nicknamed “shoebox”. Potting was risky, possibly reducing the performance of the resistors through heating and mechanical stress. But it turned out fine, as week-long measurements confirmed.
Right, probably very hard to design such a board with all the RF components and layout black magic. And I guess the jitter of the FPGA wouldn’t allow to use it to generate the trigger impulses for the sample and hold circuit, even if I maybe could create signals with phase shifts in the picosecond range by manually placing the LUTs with the FPGA floorplan. Interestingly the samplingrate of the CSA803 is only 200 kHz and the ADC has only 8 bit resolution. So if someone would manage to build such a frontend, the rest would be easy and such an instrument could be even done with the integrated ADC of a modern microcontroller.
Ha! That’s really cool. I love Easter Eggs like this and having you pop in and share the story of your Dad being the one behind it makes me smile. Bil, you should play the Easter Egg as and outro for a future video

Even though no electric device can be 100% efficient, maximizing the output and performance remains a challenging task, and power transformers are no exception. Complexity in the designing process continues to be one of the major challenges in power transformers. High cost associated with the high power consumption of power transformers, larger size and complexity in design may undermine the market potential.
