README
README.mdTime Sleuth
A cheap and easy to build HDMI lag tester. Through hole components were chosen to aid in assembly. Resistors and Caps are still surface mount but a larger 0805 package size.
An altera USB-Blaster is required to program the board. Firmware was created by Chriz2600 and can be found on his Github https://github.com/chriz2600/time-sleuth
For convenience the V1.1 PCB is shared on OSH Park. Please order in 1.6mm thickness. https://oshpark.com/shared_projects/Jw3gMtl8
A 3D printed case is also available but not required for the unit to function. The STL file can be downloaded from here: https://www.shapeways.com/product/DRHQ8MRWT/time-sleuth-top https://www.shapeways.com/product/R2SNB5DNT/time-sleuth-bottom

Questions
How big is the Lag tester PCB?
It measures 72 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lag tester use?
56 parts, built around the 10M02SCE144I7G, TFP410PAP and TC1264-3.3VDBTR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lag tester KiCad files?
From the citrus3000psi/Time-Sleuth repository on GitHub, at the commit this page was made from: the board is Kicad_ProjectV1.2/lag_tester.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lag tester design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
