Testing the TPS61092 boost converter from LuckyResistor: For my current project I searched for a good boost power converter which is able to deliver continuous 400mA power for various sensors. There are an endless number of good boost converters around, but not many can be hand soldered to a board. I would really like to […]
Marko Pavlin has published a new build: Testing of sensors with RS485 using PC without proper interface is not possible. Since RS232 interfaces are very rare, the interface should be hooked to USB. The interface between USB and RS485 can be soldered with one of the many FTDI interfaces with added RS485 driver, or bought […]
Bogdan of Electro Bob wrote an article on using the WS2812 level translator: Although the data sheet states that you would need at least 3.5V for them to recognize as HIGH level(70% of 5V), many seem to have no problem being driven from a 3.3V micro. With the signal regeneration that each does, it is only […]
Tom posted picture of his I2C Logic level converter project in the forum: A very easy logic level converter to translate I2C signals from, say, a 5 V Arduino to a 3.3 V slave device. Via the project log forum.
