📄️ A Tiny VU Lander
I have previously designed and build VU meter sculptures based on the classic LM3915 and the Adafruit Trinket M0 (which uses the Atmel ATSAMD21). Both of these sculptures are powered over USB. With this version, I wanted to build one in the lander form-factor that I’ve been very drawn to lately, and power it with a CR2032 coin cell.

A solar powered temperature monitor based on ATtiny85 and BME280 sensor.
📄️ Atiny85 LED Lander
This is a minimalist 8-LED circuit sculpture built around an ATtiny85 and a 74HC595 shift register, powered by a CR2032 coin cell. It began as a small handheld box design, but I later added lander-style legs to give it a more sculptural presence. Pressing the button cycles through a variety of blinking modes and scrolling LED patterns.
📄️ Attiny861 Temp Lander
I wanted to further explore the idea of using an 8-LED array in a sculpture. In my previous build, I used an ATtiny85 + 74HC595 combo to drive the LEDs and run simple animations. This time, I switched to an ATtiny861, which allowed me to drive the LEDs directly. Along with basic animations, the sculpture can now display temperature in BCD format using a BME280 sensor. It’s powered by a CR2032 coin cell, and for this build, I used 20AWG copper instead of brass. It began as a simple box frame but evolved into a lander with added legs and a central body.
📄️ Bubbly
While browsing through the electronics section of the Ax-Man surplus store, I came across these beautiful vintage seven segment displays. The tiny dome lenses on them were designed to make the digit appear bigger than they were. These were made by HP back in the 70s and commonly used in calculators. I had seem them floating around on eBay and at one point on Sparkfun's website but were too expensive to purchase. ( I was able to buy 50 of them for $10!)
