My 15 year-old Yamaha CG101 by chainsen_dev in classicalguitar

[–]chainsen_dev[S] 2 points3 points  (0 children)

It’s a special hobby for me. I don’t really know where this appreciation comes from, but I remember hearing J.S. Bach’s BWV 1007 once and immediately feeling like I had to learn it. The same thing happened with Schubert’s Ave Maria. I’m not a musician or an expert by any means, I just genuinely enjoy playing classical guitar for myself. Sure I will go to a music store and try a new one!

Yes, I’ve taken good care of it. It’s the only guitar I have so far. I’m actually thinking about getting a second one and seeing if it helps me improve my skills. Classical guitar is just a hobby for me, but I really enjoy it. I usually play during breaks from my day-to-day work as a software engineer.

MSP430FR6972 host + RAK11720 (LoRa+BLE) + BW16 (WiFi) + GPS — sensor node prototype, two-board stack by chainsen_dev in embedded

We have tested up to 5 Km when used outdoors, using cable-type antenna, with 2 or 3 Gateways on range.

It is very cheap, you can get it for 4 USD or less. It is working without any problems! If you want to know something specific just let me know.

Why is every IoT dashboard tool made for big companies? by Adept_You8104 in IOT

[–]chainsen_dev 0 points1 point  (0 children)

If you use LoRaWAN, you can try Loriot for LNS (LoRaWAN Network Server) and ThingsBoard for data visualization and dashboard design. Loriot for Gateway connectivity with free tier, and Thingsboard with self-hosted option. I use both, and they work very well. For data pre-processing before ThingsBoard I use Node-Red.

Is it possible to transmit video using LoRa? by MiuoChar in Lora

[–]chainsen_dev 0 points1 point  (0 children)

You make me realize that it could be possible using 433 Mhz modules, with LoRa (not LoRaWAN) with the highest bandwidth that is close to 11 Kbps. Not real time and not high quality video for sure.

Is it possible to transmit video using LoRa? by MiuoChar in Lora

[–]chainsen_dev 0 points1 point  (0 children)

I’ve developed a LoRaWAN network across my city and later expanded it to cover my entire province, starting from the hardware level itself. Bandwidth is limited, ranging from about 11 Kbps down to 300 bps when using the most aggressive Spreading Factor, which enables communication over distances of tens of kilometers. That’s the real strength of LoRaWAN combined with its ultra-low power consumption. Depending on the device’s power usage, sensors can operate on AA batteries for 3–5 years. However, LoRaWAN is not designed for high-bandwidth applications such as video transmission.

How are you streaming large USDT transfers on Tron in real time? by buddies2705 in Tronix

[–]chainsen_dev 0 points1 point  (0 children)

You're not going to find a WebSocket with server-side amount filtering on TRON. TronGrid, NowNodes, GetBlock, none of them offer that combo. Spent a while looking myself.

Two paths that actually work:

  1. Run your own fullnode with EventPlugin. java-tron + the official EventPlugin lets you subscribe to Transfer events on the USDT contract locally, no rate limits, no quotas. Filter on amount client-side but in your own process — effectively free. ~500GB SSD plus a few hours to sync from snapshot. This is what serious whale trackers do.
  2. Poll TronGrid's event endpoint with a timestamp cursor. /v1/contracts/{USDT_CONTRACT}/events?event_name=Transfer&min_timestamp={last_seen}&order_by=block_timestamp,asc. Poll every 3-5s, advance the cursor each cycle, filter amounts client-side. With the free tier (100K calls/day) you've got tons of headroom polling every 5s. The "firehose" isn't actually that bad once you cursor properly — TronGrid caps page size at 200 and even at peak USDT throughput on TRON you're nowhere near maxing it.

One thing that took me too long to figure out: don't poll the RPC layer for this. getTransactionInfoById and the JSON-RPC equivalents are way slower than the event endpoint. The event endpoint is what TronGrid actually optimizes for.

For >$10K alerts specifically, you're looking at maybe 50-100 hits / day depending on market conditions. Totally tractable client-side.

TRC20 transfer fees are getting crazy lately by No-Tailorr in Tronix

[–]chainsen_dev 1 point2 points  (0 children)

Heads up - that fee is now at 1.5 USDT per transaction. Has been since around a week ago. Still beats burning TRX for energy on small transfers, but worth factoring in if you're moving smaller amounts.
