![]() ![]() Getting the chip and a few other SMD support components onto breadboard-compatible breakouts proved to be challenging, and getting it working once it was there was even more work.Ī lot of the trouble was down to simple breadboarding errors, but the big problem was the input capacitance, which had to fiddle with quite a bit to get the converter to 14 volts. And it would be, except for the fact that his chosen chip, a MIC2288 switching boost regulator, is only available in an SMD package. The project is a scratch-built programmer for old-school ROM chips, a task normally farmed out to a dedicated programmer, but where’s the sport in that? Besides, this is the future, and generating the 12 to 14 volts needed should be a snap. ![]() So we often just forge ahead, plugging in our parts and hoping for the bestĪ recent veteran of the breadboard battle is, who kicked off a new project by prototyping this high-voltage boost converter on a breadboard, with mixed results. All that stray capacitance can play hell with circuits, especially high-speed stuff, but they’re so darn useful that avoiding them in favor of some other prototyping method can be really hard. We all know that solderless breadboards have their limitations. ![]()
