Figure 3a shows a NE555-based dc-dc converter, while Figure 3b uses the LM386. The circuit with the NE555 provides less total output current and power compared to the circuit using the LM386.

Surprise at what appeared to be a flaw in the design of the NE555 led to an interesting experiment and to the even more interesting history surrounding the chip and its designer.

One-shot circuits are popular choices for the on/off control circuitry. You can interface the programmable one-shot design in Figure 1 with any intelligent system, such as a PC, a µP, or a µC. The ...

[NE555]’s work is a excellent example of this technique using a fine enameled wire (you can find this on eBay as “magnet wire”), wirewrap board, and careful hand soldering.
