Dave debunks the marketing claims of self-charging Nano Diamond Batteries in the first 10 minutes using their own material. The rest of the video is cream on top. NDB Inc supposedly have a nuclear nano diamond self-charging battery that will revolution...

Review of the BattLab One open source battery life estimator tool from Bluebird Labs. A tool that allow you to measure the current and power consumption of your product in active and sleep modes and do “what if” analysis on estimating product battery l...

Part 3 of designing a better uCurrent series. Measuring the noise and consumption of the OPA189 compared to the MAX4239 using a dynamic signal analyser and an oscilloscope. Forum: https://www.eevblog.com/forum/blog/eevblog-1328-ucurrent-op189-measureme...

Three ways to get your PCB design rejected by your PCB manufacturer. 1) Imperial/Metric conversion 2) Unexpected Trace/Space specifications 3) Goofing the Gerber resolution. Forum: https://www.eevblog.com/forum/blog/eevblog-1327-3-ways-to-fail-at-pcb-m...

Two almost identical complex designs published at almost the same time? How does that happen? Let’s go back to 1996 and see how similar Dave’s PC Logic Analyser design is to one published in Elektor Electronics magazine. Forum: https://www.eevblog.

Part 2 in designing a better uCurrent. A datasheet shootout between the Maxim MAX4239 and the TI OPA189 A deeper dive into the datasheet specs from the previous video, looking at gain bandwidth product, noise, supply current and voltages,

Dave shows how to use reference waveforms to capture, compare and time correlate more then one signal at a time on your oscilloscope when you just can’t hold all those probes at once. Forum: https://www.eevblog.

Dave analyses a PCB layout from the EEVblog forum and covers all sorts of tips for SMD layout, component placement, routing, layer stackup, controlled impedance traces, supply planes and power bypassing. Original forum thread: https://www.eevblog.
