* A PICAXE-14M2 microcontroller is used in conjunction with 74HC595 shift registers and TD62783 transistor array drivers 16 of them are always on,įor general illumination, 16 are for animating the thermometer, and one to flash the tower. * 33 warm white "straw hat" LEDs running on 12V regulated "wall wart" power supply. Here are the front and back of the lightbox. When it was removed to make room for a neon sign for which I had made the This was part of the decor at the bar until July 2019, In January 2016, which is reflected in the score digits (printed on cardstock, not using actual score reels),Īs well as their star logo in the credit window. ![]() I made this for my friends who opened the North Star pinball bar in Montreal Then the thermometer decrements back down. When it reaches the top, the tower flashes faster and faster, Yellow printed on acetate and compartmentalised LEDs. Instead, I used a gradient of dark red to light Would crawl up by increments each time one hit certain targets. The original machine had an electro-mechanical animation for the thermometer, which consisted of a red ribbon that This is an electronically animated lightbox I made from the backglass of aĬentigrade 37 pinball machine made by Gottlieb in 1977. Here is the Octa Consequencer demo video. The square windows for the LEDs were made by hand using a nibbler tool, and then behind, isolator boxes with colored gels. It behaves erratically/randomly and responds sometimes to moving one's hands near the box. This basically makes the up/down pin on the counter chip floating, and ![]() The clock, direction, preset load and preset valueĬan all be set by external gate signals for extra madness.įor the direction, an "antenna" mode can be selected. Thus one can control the direction,Īs well as reset the counter to a specified binary value. Instead of the CD4029, I used the similar CD4516 CMOS presettable counter with a CD4051. Offset'sġ6 step Up/Down sequencer, and then the details of the schematic filled in from other designs like like the Baby 10, MFOS. Has 2 flavors, either ANDed with the clock thus appearing at every step or remaining on whenever a step is on. Other outputs are raw CV, CV with adjustable glide (portamento) and gate/trigger. With a separate glide control and output. The clock speed can be adjusted and there is a hold button. It's got the usual step on/off and oneĬan set the CV value for each step. The Octa Consequencer is an 8-step analog sequencer that outputs a control voltage (CV). I was thinking of somehow making some knobs that looked like cow udders, but got lazy because I have many other projects on the pile. Through the eye of the cow, a white LED indicates that the power is on (9V battery). On the back, the on/off switch, the range switch (high, low), and the output jack. Two potentiometers on the left control the oscillator rates, two 3-position switches on each side to control the wave shapes of each (sawtooth, triangle, reverse sawtooth), plus frequency and volume controls. It uses CMOS 4069 to generate waveforms which feed a 4046 VCO. I loved the container artwork, so after finally finishing the contents (which took several years), I decided to put in a little sound-making circuit, which is a slightly tweaked version of the Space4069 schematic by Synaesthesia on.
