Before I go building my own board to do this, anyone have a spare #Sparkfun "EL Sequencer" board*, or similar, that they'd be willing to sell/ship? My kid wants to do a project with #electroluminescent wire.

It looks somewhat simple to duplicate what I need on protoboard, but I'd rather not have to build my own.

(*product number COM-12781, or the #Arduino shield COM-10878, would take a substitute) #electronics #maker #diy

SparkFun Retired Products Archive Reference

In late 2024, SparkFun Electronics relaunched their website. They deleted roughly 20 years of archived product information, along with all associated datasheets, schematics and tutorials. Luckily, the Internet Archive's Wayback Machine has good records of the site, and I was able to recover links to 5934 deleted products. So here's the list:
https://scruss.com/blog/2025/03/13/sparkfun-retired-products-archive-reference/

SparkFun were great at keeping all of the product details for their retired products on their website. But that's all gone with the redesign.

If you've got some old SparkFun kit, you're going to be relying on the Internet Archive a lot now.

40 years later, still enjoy tinkering. #electronics #maker #raspberrypi #waveshare #sparkfun

Anyone have an old #SparkFun RED-V board collecting dust in a drawer?

I'd be happy to pay you for it (including shipping). Feel free to DM me.

TIL about the SparkFun SerIO board. This now-discontinued product is an even-simpler-than-Arduino physical computing device. When connected to a USB port, it appears as a serial device. Send it simple commands at 57600 bps and it will read/write pins for you. For example, this configures Pin 13 as an output, and sets the value high:

> C,13,1
Pin: 13 Input/Output: 1
> W,13,1
Pin: 13 Value: 1

Yesterday was bad freaking ass. I've started mentoring my kids' high school robotics team. (while wearing an N95) Last year, they invited my then-8th grader to be a full-fledged team member, so since she's a freshman and now I have two kids on the team, I thought I should offer up my time. Plus, my oldest is the team captain. Yesterday was the first meeting with the veterans and the kids who want to join this season. I love quirky high school nerds! They are sweet and kind. They're curious and excited. And that was just watching the slide deck full of typos and mistakes. And kids who made the slides with mistakes laughed at themselves, making the whole room laugh. I defy you to hold a straight face with 50 neurospicy laughing teenagers. It was a delightful afternoon. I know less than nothing about robots, so it will be an interesting school year. But sometimes, it's good for kids to see adults learning and making mistakes alongside them. So that'll be my job, I think. That, and ensuring everyone is fed, gets on the plane, and is in their assigned hotel room at lights out. ;) Today, we are building XRP bots to eventually play full-contact soccer (football) as practice for building our big FRC bot in January. Wish me luck!

Look at these beautiful little RP2350 jewels.
Can’t wait to start hacking on them!
Looks like they run the Pico2 build of #CircuitPython just fine!

So I've got a #SparkFun weather module I've been running #MicroPython on for a couple of years. It's almost perfect and I'd leave it alone except that:

* MicroPython doesn't support power management *facepalm*

* MQTT has been the Achilles heel on this project, and when something goes wonky in a few places it utterly misses what's going on and can't reset itself against @homeassistant so it juat kinda disappears.

Sooooo close

So I'm doing a quick rewrite into #ESPHome and accepting that I was only mostly successful on the original code.

TIL about #SparkFun's MicroMod ecosystem of carrier boards, feature boards, and processor boards. If it works as advertised, it could be a pretty sweet prototyping tool.

Finally, I've created a #RISC-V #Assembly code which works! https://gitlab.com/vazhnov/native-blink_asm_sparkfun_red-v_thing_plus/-/blob/main/Blink-all-GPIO_asm/src/gpio.S
Thanks to #PlatformIO, #SiFive and #SparkFun.

This new "Dynamic NFC Tag" board from #SparkFun looks pretty neat. Acts like a programmable NDEF NFC for use w/ iPhone & Android and has chainable Qwiic / StemmaQT I2C connectors https://www.sparkfun.com/products/21274
