A smaller and much cheaper version of the automaton motor controller.
A mistletoe decoration for a new years party, the balls are made from beer can widgets and the leaves are made from flattened plastic tube, the whole thing illuminated with white LEDs salvaged from a cheap LED headlght.
Tools for the job - pallet breaker
Pallets are a great source of free timber, unfortunately the nails used in their construction makes it difficult to dismantle without smashing the wood, so I made a tool..
Needing a simple way to make a small motor do a sequence of motions I made a controller using my favourite
microcontroller the PIC10F322 and an h-bridge IC.
It seems I'm not the first to discover that 0.68mm diameter pogo pins fit perfectly into a Pickits connector, obviating the need for an ICSP socket on the target board.
Tools for the job - plastic case cutter
One of the most useful skills for a maker is the making of tools.
Even though tools exist for most tasks it is often easier to make a tool for a specific job than finding a commercial product which can often take longer and cost more.
It is common these days for many products to be contained in glued together plastic boxes, though these
boxes generally have an obvious seam where the two halves are attached no amount of prying will separate them,
the only option is then to cut them apart.
So I made a tool... More here.

DC Motor Controller
A recent project required the control of a sizeable 12 Volt DC motor, the resulting
PWM motor controller was somewhat over-engineered, but useful lessons were learned in the process.
A friends need for somewhere to hang the dinner triangle gave me the ideal opportunity to make use of
a recently aquired anvil to bend some iron.
A cheap alternative for lightweight Arduino projects using an Atmel ATTiny44 and making use of the
MIT high-low tech programming ATTiny with Arduino
1.0 to allow the use of the arduino development environment.
Tabbed Box Maker
After making a box with tabbed contruction for a home theatre keyboard,
I realised that a tool was needed to make the tabs accounting for the width of the cut to
ensure a tight fit of the joints.
Small Crate Storage
Years of scavenging materials have left my workshops congested, I needed a compact storage
system in order to sort the parts. A local discount store was selling cheap small plastic crates
(30cm x 20cm), so I decided to base a storage unit on them.
Five Bar Gate
A lightweight gate made of pine and steel tubing with hand made hinges and latch.
