The Logic Pirate is an inexpensive yet capable open source logic analyzer. For just 30 bucks it can sample 8 channels, 256K samples per channel, at a blazing (overclocked!) 60 MILLION samples per second! It’s designed to support the SUMP logic analyzer protocol on Jawi’s open source software that works on most platforms.
Its big brother the Logic Sniffer is great, but this little one looks more appropriate for simpler sniffing of all digital things, and more portable (always appreciated for hackers on the move).
Dave at EEVBlog receives Doug Ford, former head designer at Rode Microphones, who explains the basics of how microphones work, the different types – carbon, dynamic, ribbon, condensor/electret, and how the omnidirectional pattern works.
Tymkrs created a component-level modular analog synth platform based on solderless breadboards and a 25 keys keyboard. This setup should make synth prototyping (and transport) so much easier! Good work!
