mini Sparkle Motion prototype - a tiny, fully-featured WLED board ✨🔌📏💡🌈

We're doing a lot of serious testing with our WLED mega-board, code-name Sparkle Motion .

While doing some holiday lighting projects, we also wanted something slim enough to slip into any design. It still uses an ESP32 for the best support, with USB-serial programming, 5A fuse, 5V level shifting + 100 ohm series resistors for pixel drivers, user/reset buttons, a user LED and onboard neopixel, JST SH analog/digital connector, QT I2C connector, 4 GPIO plus power/ground breakouts, and USB type C power/data input.

However, this version is made simpler and less expensive by dropping the DC jack and USB PD support: it's only for 5V strips if you want to power them directly (you could still drive 12V or 24V pixels, but you'll need separate power for them). Instead of a full set of terminal blocks for 3 signals, we only have two outputs, and they have to share the power and ground pins. It could also be used for a single two-pin dotstar LED setup. We kept the built-in I2S mic but dropped the on-board IR sensor - if you want an IR sensor, you'll be able to plug it into the JST SH port with a simple cable or solder it into the breakout pads.

The trade-off is that it's much smaller and slimmer, especially when no terminal blocks are soldered in by default: only 1.2" long x 0.785" wide (~1 sq in) x 0.3" thick vs. the original's 2" x 1.3" (2.6 sq in) x 0.55". To get it that small, we went 4-layer to give us a nice big ground and 5V plane in the middle and double-sided assembly. Coming soon.

I can't believe I haven't asked this earlier; but have you ever seen a port like this before? A while back I researched everywhere to try and find a replacement for the speakers on this CD player and I'm at a loss when it comes to even finding a name for this type of thing. It's from this brand called AudioLogic which I can find next to nothing about, so I can only assume they're defunct and have been for a long time. One of the speakers is broken, and the other is missing, so unfortunately I can't really demonstrate them actually plugging into this.

I'm not really all that knowledgeable in audio, but those look like JST 2-pin connectors. Given that they say "IMPEDANCE USE 3 OHM", it sounds like they're just being hooked directly up to some speakers. Like, stereo systems like this usually have speaker terminals, but I think they just used JST connectors to make it a little easier to connect.

So you should just be able to get a set of passive speakers, approximately match the impedance, and get some JST connectors to use as speaker wires.

Moisture sensor development - 2022/23

Multiple sensors have been running over winter 22 to summer 23 and some problems have arisen:

One temperature sensor stopped functioning but in a way that eluded the error detection. The symptom was that the two sensors showed exactly the same measurement. This turned out to be a configuration issue, where both sensor were mapped to the same temperature.

Battery life was too short on a couple of sensors. This may be because of poor quality batteries, poor connections in the battery holder or due to excess drain somewhere. After experimentation with better quality batteries (Samsung 25R rated at 2500 mAh) it seems the main problem is poor quality batteries.

Moisture sensors losing discrimination. On a new sensor the range from wet to dry is typically 900 but this reduced to 270. I found that cleaning off the old silicon sealant, cleaning the board and resealing brought the readings back to normal.

Moisture sensor connection. The waterproofing with silicon and the JST connector are a poor design. Securing this connector with a zip tie helps to secure this connector.

Rusty main board. One device failed due to rust getting into the pins and socket on the main board connector. This is evidence of moisture in the device container. The sensor cable entrance is sealed with a large amount of silicon sealant which often fails. However when a second device also failed, having drained new , quality batteries very quickly, it seems that the idea of using socket strips on an outdoor device, however well sealed, is a mistake. In any case the board and the chip are really the only significant components so they may as well be soldered together.

One sensor on a public Tiny Forest was stolen. This despite being well - hidden and having a notice inside the box explaining the scientific purpose of the device.

I had considered changing the design of the PCB to avoid the use of a ground plane since I found this made soldering to ground terminals difficult and poor connections created problems. On reflection, my problem is probably insufficient thermal inertia in my small iron and the use of a better, temperature-controlled iron would solve this issue whilst retaining the benefits of a ground plane.

Labels printed on a label printer fade very quickly in sunlight.

An error in the code for the test phase meant that sleep time could be negative with odd results.

It has been suggested that over-the-wire updating of the code should be implemented but I am concerned about the current demand,

Improvements

Have a working set of all three sensors which can be plugged into a device to check the cause of a failed sensor.

Replace the cheap 18650 batteries with Samsung 25R flat top batteries.

Solder the chip directly to the PCB instead of using a socket strip

Develop a better sealing system for the cable entry.

Use a chinagraph pen for labeling

Reconsider strategy for protecting devices in public places

Design 2 & Extension board design

After ordering and examining my design, I decided to swap around the extension connector and the IMU slot, as it increases the clearance for the battery JST connector.

This design ends up simplifying the traces too, so it's better overall. I also made a simple Extension board, inspired by the official SlimeVR extension board for BNO-Style slimes. It's a very simple design, designed with holes to fit in a case that I'd make if I had the time.

Here is what it looks like along with the schematic. One of the pins connects to nothing to make it compatible with the official SlimeVR extension cables, although cheap ones from aliexpress can also be bought. I made a massive mistake when I first made this PCB though, as I hooked up all of the traces backwards and ordered them like that, so I now have 5 almost-useless PCBs. This design flaw has been rectified but if i want to use those PCBs I will have to custom make some cables that go from connector 1 to 5, and so on.
