[product] comparison of programmable bus devices from glasgow interface explorer
https://www.crowdsupply.com/1bitsquared/glasgow it’s a new greatfet/buspirate device. i originally found the goodfet when i was opening free device samples to repurpose the chip, it used the same controller (but the fuse in the sample would have needed voltage glitching). the glasgow is apparently fpga-based and supports dynamic voltage and multiple device cascading. this was a fun advertisement for a crowdfunded tool that crowdsupply emailed me. they do sadly hilight a commercial centralised service for data logging. i attached the comparison as txt but the columns are not aligned.
here is the chart as html. my device stopped glitching around pasting it after i sent the previous email.
