Art Cart

Scrap wood challenge for myself. All the wood was offcuts from previous endeavours. Made to fit snuggly under my desks out of the way. @ Tainan, Taiwan https://t.co/VoGSyJlZyU

LEGO Mini Caravan Cars
Some demo cars I made for an activity I did with my students. The idea was to give every student a common base to build from then all the cars could be linked into a train or caravan at the end. https://t.co/CDTKQqAqx9

LEGO Atomic Spinny Thing.
Saw something similar on LEGO Ideas and felt like replicating the concept with the pieces I had available. @ Tainan, Taiwan https://t.co/jrZahY4cXy

LEGO NAND logic gate. #almostsuccessful
Based on differential gears. Besides having one state not accounted for in the truth table, the thought of link several of these together for a full adder was… https://t.co/Sxq6hnTu9U

Rotational NAND gate. #fail
Full analog nand gate. Everything works except for one state where both inputs are on. Built around four differential gears.

Transistor and NAND gate prototypes. #fail
Most of this batch used a weight acting against an input force and gravity to function a switch.
Not great but at least some ideas were played with to introduce powered… https://t.co/Gq98nGe73f

Failed attempts at an absolute directional drive shaft. #fail
Acts in the following manner..
Bidirectional input is converted to two single direction outputs. @ Tainan, Taiwan https://t.co/6xMISU423N

2-bit Adder #fail
Chained two full adders together. This is where friction really became too overwhelming. Need to redesign to include a buffer or some other gate or mechanism to reintroduce power into the… https://t.co/WL4MK0UTUM

Rotational full adder. #fail
For the last year I've put a lot of time into building components for an analog Lego computer. I've made many different components with varied success and failure. I am documenting all… https://t.co/cYjtqsJagw
