EYE on NPI – MicroCare TidyPen 2 #EyeOnNPI #DigiKey #Adafruit @MicroCareNews @DigiKey @Adafruit

In keeping with the holiday themes for EYE on NPI, this week (video), we’ve picked up some MicroCare TidyPen 2’s – great for removing sticky residue on PCBs from protective tapes or adhesives, or even price-tags from gifts!

These are great for rework desks, crafting, or prototyping when you have a sticker you’ve removed and it left some gunk on the PCB. They work a lot better than isopropyl alcohol (that just seems to smear the glue around) and comes in a handy little pen.

Since we use no-clean flux solder, sometimes we have some flux deposits left over after through hole soldering. This works pretty well there as well. If you really just want a flux remover pen, and not for general adhesives, there’s a special product they make just for that.

We especially like the solid felted nib. You can press it down to get some more fluid into the tip, and it’s firm enough to act like a little scrubber brush.  After wetting the area and giving it a little scrub, I use a dry tissue to wipe it clean. You can also order more nibs if they get kinda dirty or smooshed, although I think you could probably cut the nib with diagonal cutters to get a fresh tip. It’s kind of magical, we had way too much fun cleaning off sticky tools like our scissors which had a bit of goo left over from cutting some tape.


  • Dissolves and lifts away labels, glues and adhesives of all kinds
  • Great on almost any sticky residue
  • Zips away adhesives, tape residue and pressure sensitive marking tags
  • Works on paper labels, stickers, EPROM labels, Kapton® tape residue, barcode labels, chewing gum, tar and price tags
  • Removes corrosion from the gold fingers of PCBs
  • Compliant in all 50 US States

The TidyPen 2 is available right now at Digi-Key in single pieces and multipacks, toss it into your cart and next time you get your order in, you’ll thank yourself for the gift.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
