Sequence Indexer, Episode 18: TIS-100

Published on Sep 20, 2017

Basket starts the Sequence Indexer over, fights the order a stack memory node gives values back, and gets every test to pass after about an hour.

Sequence Indexer Part 3, Episode 17: TIS-100

Published on May 10, 2017

Basket rewires the Sequence Indexer's signals, squeezes a line out of the lookup, and steps through a test until the bug turns up: the lookup never reads from below.

Sequence Indexer Part 2, Episode 16: TIS-100

Published on May 8, 2017

Basket tries to turn Sequence Indexer's stack around by pouring it into the second stack, adds a wait signal, and is still arguing with a zero when the video ends.

Sequence Indexer, Episode 15: TIS-100

Published on May 5, 2017

Basket starts the Sequence Indexer, fills a stack memory node with the sequence and writes a lookup that counts down, then finds the stack hands the numbers back in reverse.

Signal Divider, Episode 14: TIS-100

Published on May 3, 2017

Basket divides by subtracting over and over, gets Signal Divider to pass in seven nodes, then rebuilds it in six after a storage node listens to the wrong side.

Signal Window Filter, Episode 13: TIS-100

Published on May 1, 2017

Basket tries to keep a rolling window of values in stack memory, starts over, and gets both sums out of a chain of nodes once the three-value sum is sent down twice.

Histogram Viewer, Episode 12: TIS-100

Published on Apr 28, 2017

Basket trims Image Test Pattern 2 to two lines, then builds Histogram Viewer from borrowed drawing code, chases bars that come out with gaps, and passes it by guessing the height.

Exposure Mask Viewer, Episode 11: TIS-100

Published on Apr 26, 2017

Basket borrows code from two solved puzzles to draw rectangles from four numbers, runs out of room in a node, and gets the picture to print after one wrong direction.

Image Test Pattern, Episode 10: TIS-100

Published on Apr 24, 2017

Basket learns how the image panel takes coordinates and colors, fills Image Test Pattern 1 with white from one node, then draws the checkerboard of Image Test Pattern 2 with two.

Signal Multiplier, Episode 9: TIS-100

Published on Apr 21, 2017

Basket learns the stack memory node on Sequence Reverser, then builds Signal Multiplier from a loop of additions and finds out the hard way that the inputs can be zero.

Sequence Peak Detector Part 2, Episode 8: TIS-100

Published on Apr 19, 2017

Basket rebuilds Sequence Peak Detector around two storage nodes, chases a zero and a stray -1 through breakpoints, and gets it passing with a 999 trick.

Sequence Peak Detector, Episode 7: TIS-100

Published on Apr 17, 2017

Basket starts Sequence Peak Detector from an empty grid and spends the episode writing min and max code, running short of lines before ever pressing run.

Signal Pattern Detector, Episode 6: TIS-100

Published on Apr 14, 2017

Basket builds a detector for three zeros in a row, gets it passing with six nodes, then rebuilds it with four after fighting a jump that will not land.

Interrupt Handler, Episode 5: TIS-100

Published on Apr 12, 2017

Basket gets Interrupt Handler to pass after rereading what the puzzle asks for, then trims the program from 65 instructions to 54.

Differential Converter, Episode 4: TIS-100

Published on Apr 10, 2017

Basket goes back to passed segments to cut their cycle counts, halves the Signal Amplifier's time, then starts writing the Interrupt Handler.

Sequence Counter, Episode 3: TIS-100

Published on Apr 7, 2017

Basket passes two segments in one video: Sequence Counter, after one wrong line eats a value, and Signal Edge Detector, after it trips on a change of exactly 10.
