Fishing is generally thought of as a relaxing and laid-back activity, but it still requires a certain amount of physical strength and dexterity. This can be a problem for older anglers or those with physical disabilities. To bring back the simple joy of fishing to those who may no longer be able to hold a rod on their own, [Ozz] has been working on the FISHBOT.
The FISHBOT looks like a miniature crane, complete with an electric motor and winch to pull in the line. But there’s a bit more going on here than meets the eye. Anyone who’s tried to land a large fish knows you have to be cautious of snapping the line, so [Ozz] has added a load cell to the system that can tell when its being pulled too tightly. In the future he hopes to make this feature a bit smarter by taking into account additional variables, but for now it should at least keep the more energetic of your quarry from getting away.
[Ozz] is controlling the beefy 400 watt motor with an IBT-2 H-bridge module connected to an Arduino Mega. The electronics can communicate with the user’s smartphone over a HM-10 Bluetooth module, which allows for more advanced features such as gesture controls that utilize the accelerometer in the phone. Long term, it sounds like he hopes to use the microcontroller in conjunction with the load cell to pull off more advanced tricks like weighing the fish and sending the data off to the user’s fishing buddies to show off.
In the past we’ve seen a drone used to get a lure out where the fish are, but catching one and reeling it back in is a very different challenge. It looks like [Ozz] still has some work to do on this project, but so far it seems things are going well. Being able to return a simple pleasure like this to those who thought their fishing days were behind them will surely prove worthy of the effort.

For those of us who can’t get enough vicarious machining, YouTube is becoming a gold mine. Intricate timepieces, gigantic pump shafts, and more and better machine tools are all projects that seem to pop up in our feed regularly.
With all that to choose from, can a series on building a fly fishing reel actually prove interesting? We think so, and if you enjoyed [Clickspring]’s recently completed pedestal clock, you might just get a kick out of what’s cooking in [JH Reels]’ shop. Comparing any machining videos to [Clickspring]’s probably isn’t very fair, but even with a high bar to hurdle, [JH Reels] comes out looking pretty good. The challenge here is that this is a saltwater fly reel, so extra care with material selection and machining methods ought to make for some interesting viewing. Also of interest is the range of tooling needed to produce the reel. From lathe to mill to waterjet cutter, a lot goes into these parts, and watching them come together is fascinating.
You wouldn’t think a seemingly simple mechanism like a fly reel would be so complicated to build. But there’s a lot more to it than meets the eye, and with a reel that’s clearly destined to be an heirloom piece, [JH Reels]’ attention to detail is impressive. The series currently stands at 10 videos, and we’re keen to see how it turns out.
The first video is posted below to whet your appetite. But if machining and fishing don’t do it for you, maybe you can try drones and fishing instead.

Whether it’s a new rocket, your latest quadcopter, or [Charlie Brown]’s kite, it always seems like there’s a tree waiting to catch and eat airborne projects. Sometimes you get lucky and find a way to climb up the tree to retrieve your wayward build, but most times you’re reduced to looking for rocks or sticks to fling up there in an attempt to shake it loose. But if you want to improve your chances of getting your stuff back, [U.S. Water Rockets] has a build for a retrieval tool made mostly from scrap bin parts that will help.
All you need is some PVC tubing, an old fishing reel and line, some latex surgical tubing, and a few dowels for projectiles. You can tell everything about the build from the BOM and stills, but the video after the break gives detailed instructions and shows it in action. Adding some fins to the dart or even substituting a cheap arrow from the sporting goods department of your favorite retailer might help with your aim. Even without fletching, the accuracy of the launcher is pretty good, and the range isn’t half bad either. Once the fishing line is over the branch that ate your quad it can be used to haul up successively stouter ropes, and pretty soon you’ll be shaking the tree like a boss.
Even if getting stuff out of trees isn’t on your immediate to-do list, this little hack could be put to other uses. Hams will use it to loft antennas up into trees, and tag-line placement for tree removal could be simplified with this tool. But if you still find yourself needing to retrieve stuff, you might want to be proactive and make your aerial robot tree-proof. That still won’t eliminate the need for drone-on-drone rooftop rescues.

Need some gears? Got a timing belt?
[filespace] sent in a neat build he stumbled upon: making gears with plywood and a timing belt. Just cut out a plywood disk and glue on a section of timing belt. There’s some math involved in getting all the teeth evenly placed around the perimeter, but nothing too bad. Also useful for wheels, we think.
Huge chess sets are cool, right up until you try to figure out where to store the pieces when they’re not being used. [Jayefuu] came up with a neat solution to this problem. His pieces are cut out of coroplast (that corrugated plastic stuff political campaign signs are made of), making it relatively inexpensive and just as fun as normal giant chess pieces on a tile floor.

[Randy]’s son is in the cub scouts. Being the awesome father he is, [Randy] helped out with this year’s pinewood derby build. It’s a car shaped like a portal gun with the obligatory color-changing LED. The car won the ‘Can’t get more awesome’ award, but wheel misalignment kicked it out of the competition during qualifying rounds. Sad, that. Still awesome, though.
These people are giving you tools for free
Caltech professor [Yaser Abu-Mostafa] is teaching a Machine Learning class this semester. You can take this class as well, even if the second lecture started last Thursday.
Turning an Arduino into a speech synthesizer
[AlanFromJapan] sent in this product page for an Arduino-powered speech synthesizer. We’re probably looking at a relabeled ATmega328 with custom firmware here; to use it, you replace the micro in your Arduino Uno with this chip. The chip goes for about $10 USD here, so we’ll give it a week until someone has this proprietary firmware up on the Internet. There are English morphemes that aren’t in Japanese, so you can’t just ‘type in English’ and have it work. Here’s a video.
Six things in this links post. We’re feeling generous.
What would you build if you had a laser cutter? [Doug Miller] made a real, working fishing reel. No build log or files, but here’s a nice picture.
