I’ve been fortunate in being able to borrow expensive equipment like an oscilloscope and photometer from helpful colleagues. 

When	What	Where	Details/Quantity	How much (£)	Why
2005	Matrix 2500 SXGA LCD projectors	Christie	2	2950	to project experimental stimuli
2005	2.0-2.6:1 zoom lenses	Christie	2	2150	to project experimental stimuli
2005	PC	Dell	Precision workstation 670 with two Xeon 3.2GHz processors and 3Gb RAM, running MS Windows XP x64.	2525	both to run neuronal simulations, and to display experimental stimuli (ultimately I hope to have separate computers for each of these tasks)
2005	graphics card	Dell	NVidia Quadro NVS 280, PCI-Express interface, dual output	came with Dell PC	to drive the two projectors
2005	graphics card	Dell	NVidia GeForce 6200 128Mb, PCI interface, single output	45	to use as display interface with computer
2005	optics equipment	Elliot Scientific	2 glass linear polarising filters, both mounted in lens mounts and posts, one in a rotary mount, plus an optics breadboard	400	to carry out accurate measurements of polarisation
2005	ST-Prof-DC black-tinted rear projection screen	Screen-Tech	1m x 80cm x 3mm	290	to display the stereo images on
2005	4 plastic linear polarisation filters	Screen-Tech	4, each 20cm x 20cm x 0.8mm	280	to separate the two images
2005	cardboard passive stereo glasses	Screen-Tech	50	31	for informal viewing and checking
2005	used shelving	Used Storage Systems	8 5-foot uprights, 4 1m x 60cm shelves	30	to put the projectors on
2005	DMS to dual DVI cable	Stuff-UK	1	30	to connect the dual-head graphics card to the projectors’ DVI inputs
2005	retort stands and clamps	Nicholl	2 bases, 4 bossheads, 4 clamps	100	generally holding photometer heads, light sensors, screen samples etc in place
2005	VGA-5BNC cables	Maplin	2	40	connecting graphics card output to oscilloscope
2005	oscilloscope probe	Maplin	1	20	monitoring voltage across photodiode as a crude lightsensor
2006	UHCOTech HeadSpot headrest	UHCOTech	1	250	support observer’s head in a stationary position during experiments
2007	Leica Disto A3 laser distance meter	LaserLevel	1	200	accurate measurement of distances
2007	laser digi-angle measure	LaserLevel	1	190	accurate measurement of angles
2007	Laserliner Autocross Laser2 marker and mini crank tripod	LaserLevel	4 of each	670	to project a crosses onto the screen (automatically aligned with gravity), thus providing vertical and horizontal references for accurately aligning images.
2007	Dell Poweredge 840 servers	Dell	2, each with 4 processors and 4Gb RAM	2600	simulation machines
2007	Dell Poweredge sc440 server	Dell	1	2600	lab fileserver
2008	Stereo projection system	Virtalis	2 F20 sx+ DLP Projection Design projectors, 2 polarising filters, Stewart Filmscreen 150 screen 2.7m wide x 2m high, installation	18000	for stereo experiments where I want a wide field of view, and/or because the subjects would find using a mirror stereoscope harder than 3D glasses.
2009	big chunky coloured AbleNet switches plus interface boxes	Inclusive Technology	8 switches, 2 interfaces	328	for psychophysics experiments with small children
2009	mirror stereoscope	Elliot Scientific	2 mirrors, 2 beamsplitters, 4 holders etc	350	for stereo experiments where I want the pixels to be as small as possible
2010	touchscreen	telboy1505 on ebay	15 Inch Touchscreen LCD Monitor with VGA, Model CVJU-E38	170	for small children to indicate their responses
2010	DATAPixx	VPixx Technologies	DATAPixx lite video display system	1045	to obtain 16-bit control of contrast
2010	RESPONSEPixx	VPixx Technologies	RESPONSEPixx 5-button response box	515	to record subject responses with micro-second precision and be able to light up buttons to give cues
