This video explores the effect of DC Bias on Class II MLCC Capacitors and why once you’ve deployed a ceramic capacitor in your circuit, the capacitance may not be the same as the specified value. https://www.youtube.com/watch?v=HMNwBKOIGfs SDGEE #066 – MLCC Capacitors Schematic for the Capacitor Tester Above is the schematic…
Here we have a nice high power soldering station for those that want something a little more professional for their electronics work. It’s essentially the same as the popular JBC soldering station but at around half the price. The unit I obtained from Banggood unfortunately had the Chinese UI, but…
This video describes a DIY Vacuum Pick-up tool for picking and placing parts from an SMD component tape. The basic design for this tool involves using a vacuum pump and a solenoid to control the vacuum to a handpiece under control of a foot pedal. https://www.youtube.com/watch?v=1FnGqH_WkL4 By applying vacuum to…
A Stereo Microscope for SMD Rework – Worthy of a look if you’re looking for a low cost microscope for your lab. I found this have excellent optical properties and amazing working distance.

I’ve recently been working on a Trailing Edge Dimmer for controlling AC powered LED Lamps. The progress is documented in the YouTube video below: https://youtu.be/QHQGl3KQhGU Schematics for the dimmer circuit can be found here: dimmerdemoMULTIFETDownload
https://youtu.be/bGkbXPUzcmE A look at a 16MP CMOS Camera that can record direct to SD Card, output to HDMI and also USB interface. This one is from Banggood: https://www.banggood.com/custlink/KmDmyuomIKAnd is coupled with a 180x Lens is from Lapsun on eBay: https://bit.ly/2DRBIlT
I thought this was an interesting device, a calculator kit that also has a few electronic functions – resistor colour code calculator and LED current limiting resistor calculator. Take a look here: https://www.banggood.com/custlink/mDKDhu0ZKT
