PCB mod boards are useful for a whole range of applications and scenarios from production to upgrades, repair, and hacks. Dave shows you several examples and talks about creating manufacturing panels for them, along with castellations, V-Scoring, routing, and manufacturability. Forum HERE Podcast: Download

A look at the dual bipolar transistor zener clamp circuit, and it’s usefulness as a fast low leakage overload clamp. The first part is lifted from video #1000 with 12 minutes of extra commentary. Interview with Dave Taylor, designer of the famous Fluke 8060A multimeter Forum HERE Podcast: Download

Circuit building block time. The capacitance multiplier and how it gives almost negligible power supply ripple compared to a voltage regulator. Whiteboard theory and then some bench demonstrations and experiments. Plus a twist at the end that proves that the “Capacitance multiplier” is perhaps one of the most mis-named circuits …

An in-depth practical visualisation of how bypass capacitors work at both high and low frequencies. Bulk decoupling capacitors vs bypass capacitors. Capacitor placement and types are tested and the results examined. How package inductance can have a large effect. Loop area and what is means, it’s impact on EMC emissions, …

Dave explains and demonstrates how out of phase digital signals can effectively double your voltage. The magic of moving your reference point. And how you can verify this with a differential probe. A question bought up in the comments of the previous LCD driving video. The HVP70 High Voltage Differential …
