This is a mini UPS battery backup based on Linear Technology’s LT3652HV. The HV is a high voltage version that can charge upto 4 cell Li-Ion batteries. Other chemistries are also supported. This one supports charging using a solar panel…
A laser cutter/engraver is an incredibly useful tool and the things you could do with them are limited to your imagination. I tinker with a lot of electronics and build boards that mostly have a lot of SMD components. I…
I needed a dual output power supply that could power a hard-drive. I later realized that today’s newer hard-drives use a single supply of 5V. However by that time I had already designed this one. So I thought I’d build…
This is a high efficiency voltage regulator with more than 90% efficiency in real-world tests. It is based on TI’s TS54331 chip. This is a switching regulator and is configured for 12V at 2A. However, any other output voltages can…
