Remote Control

I first thought of building this, because I printed a quad-copter frame, and bought a flight controller, motors and propeller to go with it. I thought I would connect a Wemos D1 mini to the flight controller. Then if I wanted to fly it, I'd need a WiFi remote control.

I had two thumb joysticks and Spark-fun breakout boards I bought a long time ago, and never used, so I set about designing something. I also had various ESP 8266 modules to choose from. Having designed and printed something around a NodeMCU V2, I realised I'd made a silly mistake: There's only one analog in. You can often work around this by connecting and disconnecting the power from the various inputs, but that's not possible with these breakout boards. I got a cheap ADS1015 breakout board, and squeezed it in the corner of the box.

It's all a bit of a squeeze: I should have made the box a bit bigger. I always underestimate how much room wires take up. I also thought I'd made it for 30mm screws, and it's too thin. It all fits somehow anyway.

Anyway, I'm planning to use it with the robot arm now. The quad-copter can wait.

3D Printer ramblings

 I have a Prusa i3 mk2.5 in storage. I used to use it in my shed I used not to worry about it's harmful emissions: I just didn't share the space with it. I had, however, added an enclosure, and was planning to add a HEPA filter too it. Once it's in an enclosure, it's massive. Even if I had added the filter, there's no where to put it. I'd like a small printer that has an enclosure or is easy to enclose. I figure I could get by with 150x150x150 build area: I was rarely patient enough to wait for my i3 to print bigger models. 200x200x200 would probably actually replace my current printer, so that would be a bonus. Not many printers have HEPA filters, which is really a shame. It seems just to be the result of a misconception about HEPA filters, and about filtration in general. Read this . E.g. I was looking at a used Lulzbot mini, and there are ready made enclosure s for it, however . In this particular case, it's no big deal: opportunities to buy a Lulzbot min

Balance Bot V2

My current balance bot sort of works, but it's surprising it does: it's centre of gravity is actually only about 60mm above the motor axis. The whole thing ways 320g. The 6 AAA batteries only weigh 70g, so despite being right at the top, the don't affect the centre of gravity much. 6 AA batteries would weigh about 180g. That would add a 34% to the overall weight, and move the centre of gravity much higher. Seems like a dramatic increase in weight: it would be nice to be a bit more incremental. More AAA batteries isn't really worth considering: they only weight 12g, vs 30g for an AA. 4 AA would deliver much less power/torque, so that's no good. There's no middle ground, in other words. I'm also going to make the whole thing a bit taller: I need more space to add more sensors in any case. Last time I made the frame, I needed an elaborate jig to get it square and it actually didn't work that well. This time, I decided to use some short bits of a

Robot arm

Image
I 3d printed this robot arm I original found on Thingiverse, but the Instructable is recommended. There's a MK2, and also a delta style arm, both of which look like good alternatives, but this will do for now. Here's a video of it moving: I've attached it to an STM32F4 Nucleo board, via a prototype shield: In the video, I'm sending commands from a python script that runs on my desktop, communicating via USB serial. I've written an implementation of canonical s-expressions in c++ that doesn't require memory allocation, as well as a python version to talk to it. It's the main reason I haven't posted for so long, and of course overkill for just controlling some servos, but should prove more generally useful. Here's the code . It uses platformio for the build, and mbed rtos.
