FindDay #4

Every Friday I share the five coolest things I’ve found on the web in the last week.

1 – Mooshimeter Wireless multimeter

This might sound illogical at first, but how many times have you had your scope, meter, etc. connected to something but then had to walk away from it to trigger the system you’re monitoring? The most obvious example to me is when you’re working on a car, but the same thing is true for anything big enough to block your vision (HVAC, washer/dryer, etc.).

This little device lets you use your phone as the display for a basic multimeter/Oscilloscope. It’s not the most high-performance device available, but it’s inexpensive ($100) and looks pretty durable.

2 LitePlacer


While researching DIY pick-and-place machines I came across LitePlacer. It’s the first sort of professional-grade device of it’s kind aimed at the (large) desktop market that I’ve seen. What I’m looking for is something smaller and open-source, but I was impressed with the quality of the LitePlacer device, documentation and non-obnoxious website.

3 Feather 32u4 FONA


I’ve been looking for something like this device for a long time. I’ve made several different runs at designing a device to replace my smartphone but all of these projects run out of gas because what I’m able to cobble-together out of discrete boards and modules ends up being more than I want to carry around in my pocket. This leads down the road of designing custom boards (with surface-mount parts) and while there’s nothing wrong with that, so far I haven’t made it through the other side of that tunnel.

So when I came across the Feature 32u4 FONA I was very excited. The device combines a SIM800 cellular module, an ATMega 32u4 microcontroller and a lithium-ion battery charger into a single integrated board with all of the necessary circuitry to glue it all together. These three things make up the bulk of the parts necissary to make a phone-like device, minus the input/output components and any other specialized bits.

The ATTMega 32u4 might be a little under-powered for some of my previous designs, so I’ve started an entirely new design that is centered around being the minimal viable replacement for my smartphone. I’ve got a couple other projects in-progress that I need to wrap-up before I dive into smoething new, but I’ve been waiting a long time for something like this so I’m hoping to get started on it soon.

4 Retrofuturistic arcade cab


I ran across this while researching cabinet designs for the Charity Arcade project. The design wasn’t right for my project, but it was so cool that I wanted to share it.

5 Hangprinter

This is the most exciting thing I found this week. Every since I built my first 3D printer, I’ve wanted to build another one. I’ve started a few, but for various reasons I never seem to finish them. I think the biggest reason is that in the amount of time it takes me to build one, the technology improves and I loose interest in building whatever I started.

The Hangprinter strikes a balance between simplicity (at least in terms of construction) and capability that I think will easily remain relevant long enough for someone like me to finish building it.

With potentially unlimited build volume, the Hangprinter is unlikely to run out of build area even for the largest jobs. Paradoxically, since the entire printer is housed in the “print head”, it’s incredibly portable as well.

The design isn’t ideal for everything (fine details are not its strong point) but in terms of building large parts and doing it on-site, it would be hard to beat. It’s also exciting to see some innovation in the 3D printing field as opposed to just evolutionary improvements on previous designs.
