Best trick to strip wire in the middle (to connect elements in the middle)

I have a simple 22 AWG wire that needs to connect to multiple elements. Every connection is a solder joint. I would rather not cut up small wires, as it's for a batch run. Normally I'd love to use daisy chained wire harnesses (google it) to connect…

Powering ws2812b led strip with ATX power supply

So, I'm planning on doing a little project. I have 8years old ATX power supply from an old PC, and I want to use it to power my LED strip (ws2812b). It is a 300 led strip (5m strip). I know for that length I will need 5V/18A of current but my PSU is…

Will this MOSFET be suitable for driving a 12V 1-2A Load from an Arduino?

I have an Analog 12V RGB LED strip (which only requires 1-2 amps at most) that I want to control using an Arduino Uno. I looked into how I could go about doing this and saw that i could use several Logic Level MOSFETs to control the RGB pins on the…

How does one properly strip coaxial cable to nonstandard strip lengths?

For my job, I need to put SHV connectors on a couple lengths of RG-59. I have the cable, the connector, and the crimping tool, but I've hit a snag: I don't have the slightest idea how to properly strip the cable! The datasheet gives me some lengths,…

Connecting a 12V LED strip to a 7.4 2s Li-po battery in addition to two motors

I know this is going to be a completely stupid question, but since I'm working with a Li-Po I want to make sure I get this right. What I am building is a modified Nerf blaster that has two motors connected in parallel drawing 20A each (40A in total)…

How is a 'ribbon controller' called in electrical terms?

On some synthesizers, there is a strip called ribbon controller, to wipe your finger over and it detects pressure. It's a bit similar to a mobile phone's LCD touch panel, except that it is one-diagonal (horizontal only) and the accuracy is…
