ALL ABOUT BATTERIES! on “Ask an Engineer” Saturday 10pm EDT 7/3/2010. This is going to be a POWERFUL show! Batteries, power supplies, solar charging and more! – if it’s moving electrons we’re going to talk about it!

Pt 10187
On Batteries, How to decide which batteries will run your project best. – From the column DIY: Workshop By Limor Fried. MAKE 11 page 151.

What is “Ask an engineer”? From the electronics enthusiast to the professional community – “Ask an Engineer” has a little bit of everything for everyone. If you’re a beginner, or a seasoned engineer – stop in and see what we’re up to! We have demos of projects and products we’re working on, we answer you engineering and electronics questions and we have a trivia question + give away each week. Mosfet the cat stops by too.

Chat details!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. I had a question that is a little bit long to explain, but I was wondering if you guys had any experience with this kind of problem.

    So say you are trying to reverse engineer some particular device that connects to the host pcb via a wide bus. Surely you can capture the sequence of signals going back and forth, but how do you know which side does the talking?

    It is especially important for bidirectional signals. Say the direction changes somewhere in the middle of transaction.

    So the question is, is there a simple circuit that will allow capturing not only the voltage on the bus, but also the direction of the current flow. Inserting a diode seems like one possible solution, but it is very intrusive and has limited potential. What I’m looking is something that can capture both the level of the signal and directionality.

    Thank you for looking into it!

  2. @Oleksiy – stop by the show and ask this – or you can also post up in the forums, thanks!

  3. Any way we can catch up with these if we missed out on the live stream?
