9-Pin Tube Pin Straightener and Pin Alignment Tool.
“A” logo on the back is for www.AustinMics.com, where I design DIY tube amplifiers and kits… and use this tool every time!
Print slow (20mm/s) for best resolution.
The pin holes are a tight fit for USA and other quality 9-pin “nonal” tubes (valves) with rigid pins. Your experience may vary with modern, cheap import tubes and their soft-metal pins.
Occasionally, individual pin holes can sometimes be too small due to imperfections in the print.
This straightener does not remove “kinks” from severely bent pins.
The tool re-aligns to vertical, and corrects the spacing on pins that have been bent or twisted due to rough removal or improper storage.
For best results, insert and remove the tube several times, forcing the glass base to touch the plastic.
BE CAREFUL – You can still break-off or bend pins with this tool.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
