⚠️ – Some ICs (e.g., TDA series, certain CMOS chips) are obsolete. Modern equivalents may need substitution. ⚠️ Scan quality – The PDF is often a scan of an old book; some pages may be fuzzy or skewed. ⚠️ No index/search (in many versions) – You’ll have to flip through or make your own index. ⚠️ Safety – Some circuits involve mains voltage (transformers, power supplies) with minimal isolation guidance. Not for beginners without supervision. ⚠️ Missing updates – No surface-mount or Arduino-era designs. elektor electronics 304 circuits pdf
