There are a lot of Dupont crimping tools to choose from, some sold for Dupont connectors are not even the correct type! Frustrated with my old crimper, I went hunting for a better one and found these. So far it looks like it was a good purchase and I am already getting MUCH BETTER crimps.
Make LED Task Lights for Your Shop Equipment. Perform your tasks with better visibility and see details better. The task lights shown in this video are specifically for the paint booth project on this YouTube channel, however, the methodology is the same for other LED task lights too. Chris DeHut walks you through the process with plenty of details and tips.
NOTE! During the video the MAX Voltage and Current were used in the examples for the Resistor value selection. In practice, you should use a current value 10~20% less than the max current shown in the LED's specifications. For example if the max current rating for the LED is 350mA use a value that is 10-20% less than that for calculating the resistor value. For voltage, use the mean value specified in the LED specs.
OH NO! The batteries leaked in the remote! This video shows a possible solution to the problem of leaked batteries. A few minutes with a screwdriver and some household chemicals in the right proportions might fix your battery operated device.
