Here we go, it’s the W day again. Seems like the previous one was two infinities ago. During that infinite time we had plenty of opportunities to pick the interesting stuff floating around internets, and bring it to you: Headphone Light Show EL (electroluminescent) wire is a cool thing. Add it to the headphones and […]

Continuing in the tradition of mixing up the previously purely on-topic posts, we have a few things to announce today, other than bringing you still-brand-new-cool product. First off, the announcement from our Chief Geek: Make Something Useless Useful At Solarbotics, we put in substantial effort in creating kits for people to use to fulfill a […]

Got a new kit for you - the K SMD L293D Motor Driver. No, no, the SMD isn't "surface mount" - it's the Secret Motor Driver! This L293D-based motor driver fits secretly inside most standard servo cases like the Futaba S3003/S148, and our own GM4 gear motors. It replaces the low-voltage original electronics with LED-indicated, […]

What we have today are not Fairly Expensive Tortillas or Fortunately Edible Theremins,  but Field-Effect Transistors. If you know what it is, I will leave you to explore: 1RFZ44N N-Channel FET $2.50 The IRFZ44N is a very powerful useful N-Channel FET, with only 0.0175ohms resistance pushing 20 amperes at 5V! FQP27P06 P-Channel FET $0.95 A […]
