Today we finished building latest revision, and started testing the secret project firmware. We found a couple of bugs in our latest PCB design. The ‘DIR’ pin of the 74xx245 transceiver was connected to GND instead of being pulled high, and the ‘R/W’ pin of the LCD was left unconnected. We also organized in-progress projects […]

Workshop Update for July 5th, 2012
Today is Workshop Video Thursday so we spent a lot of time in filming and editing. We still haven’t found a great solution for the screen capture software. Firmware development took a hit today, as we wasted most of the time following wrong assumptions. While implementing the final “menu activated” function, we somehow broke the […]
Workshop Update for July 4th, 2012
UPS package finally corralled, and will be delivered tomorrow. A 74HCT245 will complete a long-delayed final revision of a certain secret prototype. We prepared for tomorrows workshop video on serial port interfacing. We arranged a giveaway for a coming week, and perhaps the first sponsor of the 2012 Open 7400 Competition. Today we continued contacting […]
Workshop Update for July 3rd, 2012
We finalized part kit materials, and made a round of updates to Seeed sales pages, and the wiki. We also photographed some missing parts for the master part list wiki. Code for the secret project is close to first full function testing. Only one large function is left to be implemented. Today we mostly […]
Workshop Update for July 2nd, 2012
Today we added the ATX breakout board v1.1, and an earlier draft to the free PCB drawer. We ordered a second batch of the ATX board, thanks for making it a success. A DigiKey order with some CPLDs is stuck in UPS, we’re trying to figure out how to dislodge it. Little wire giveaway tomorrow […]
Workshop Update for June 28th, 2012
Video editing, and filming ate most of our day. We did get some time to finalize our part kit list. We found a few eBay suppliers offering good wholesale prices. SMD transistors, and diodes are a bit harder to find. We also made some tweaks to our partlist to accommodate easier-to-source parts. Secret project firmware […]
