  • How to Desolder Electronic Components From Circuit Boards - 7 Tips & Tricks | Free Parts for Projects!

    A few things that I might add here:1. Heat Gun. Your blow torch idea is good, but I find that a heat gun will also do the trick, and with a lot less smoke! Just invert the board so the components' weight encourages them to drop out of the board, mount the board in a holder, and apply the heat gun on the back. You can use a long-nosed plier to encourage parts that still won't drop out. Heat guns are cheap - in the US you can get one for around $10 at Harbor Freight.2. Solder Wick. It takes some practice, but you can do a good job with solder wick. Sometimes you have to add a little more solder to the joint to get it to work, and you definitely have to frequently move to another, clean, section of wick as you work. It's also good for cleaning up a PCB after removing a bad component that y...

It's also good for cleaning up a PCB after removing a bad component that you intend to replace.3. Solder Sucker. These spring loaded suckers are great if you can't afford the cost or the space of a desoldering station. Just heat the joint, place the solder sucker over the melted solder and pull the trigger. Sometimes it helps to put the sucker tip around component lead on the back of the board, and then heat the lead of the component on the top side - when the solder flows, pull the trigger. It will suck the solder out of the hole.

  • The Best Bluetooth for your Boat (v0.1)

    Great build! I've got a suggestion to upgrade your installation: Install a Raspberry Pi (3) based OpenPlotter system, and then install a slimserver and Squeezelite. It would probably already fit in the box you have. I've got a 250gb hard disk on the system on my boat, which stores my 34K song music collection, and stores charts for Openplotter. So, with a single $35 computer (plus a few add-ons), For not a lot of money, you can have:A chart plotter (it displays on a tablet via VNC) with inputs for a cheap SDR-based AIS receiver and NMEA inputs from sounder, log, wind, GPS, etc.A WIFI hot spot and repeaterA huge music library with integrated music playerHave a look at these links:OpenPlotter: http://www.sailoog.com/en/openplotterSqueezeserver and Squeezelite: https://www.instructables.co...

    Happy to help, and perhaps I'll do an instructable when I'm done with everything. I'm also a Navionics Boating HD user, and I'm also interested in potentially streaming depth and log data to the tablet. So, I'll be using OpenCPN and Navonics on the same tablet. I sail in Mexico, and the charts are not as good, or easy to obtain, as the great NOAA charts in the USA. Have fun and good sailing!
