![]() Wearers use the glasses by staring at text they can't read and blinking to trigger the glasses. That camera can detect blinking, while the other captures text. Half of the lens is a mirror that reflects the wearer's eyes back to the first camera, which tracks eye movement. Called the Oton Glass, the spectacles are meant to translate text into audio using two cameras and an earpiece, both fitted to its frame. I can also see if I can add an optional slot for a 5W resistor.A Japanese company is in the midst of developing a pair of smart glasses that can help those with visual impairments or comprehension problems to read written text more easily. Anyway, it will be easy to add a feature on the firmware to check (and shut down) everything if a severe crossload condition is detected (& the PSU is unable to handle it correctly). Modern PSU (especially DC-DC ones) are totaly immune to crossload at such low current. But even on Old or bad quality PSUs, that issue is unlikely to happen with 50W of power drawn. On old AT motherboards, almost all the power is drawn on +5V, so if a resistors is placed, it should be placed on the +12V rail. So you have to place a resistor on the "idle" rail to add some current consumption. On very low-end (< $35) or old PSU, you can see some voltage drop or overvoltage when the current consumption between 3.3/5V rails and 12V rail is unbalanced. The potential crossloads issues are interesting. In any case, great work, it should be a great tool for a test bench. Now, I don't know if that is really necessary, but have you considered including it in your design? One thing that may or may not be important, but I have seen that some of those passive ATX2AT adapters have a dummy load for the ATX 3.3V line since 3.3V is not used in AT units and the unbalanced load could cause problems with some PSUs. If we're only a few to want one, I'll assembled them manually, but if we're more than a few, I can consider having them built by a fab to reduce costs. Some friends in the CPU collectors' community already expressed an (unexpectedly) strong interest for that adapter, so maybe some fellow retro-computing addicts here might also be interested. I'll be happy to hear your thoughts and suggestions about this project. Much more technical details are available on this page: ![]() The project will ultimately be open-source and can be adapted for any other retro-platform that require -12/-5/+5 and/or +12V. I also added a small OLED display for monitoring purpose, a -5V regulator to regenerate that missing voltage (required by some sound cards) and some additional filtering capacitors. So, I created a "Smart" ATX2AT Converter, featuring fully-programmable electronic fuses. The motherboard was FUBAR by the time I noticed something went wrong and manually switched off the power (within 3/4 seconds). That short was not "short enough" to trigger the (very large) PSU overcurrent protection. Some capacitors were shorted and my ATX PSU, coupled with a regular passive ATX2AT adapter, led to massive damage (burnt traces). Some weeks ago, I fried a nice 486 motherboard I got in a scrap lot at first boot. These boards are now becoming outrageously expensive, so it often worth the time to fix dead ones (replacing caps, etc.) or at least to avoid ruining them when they're in working condition. They all works with the infamous P8/P9 power connectors. I have a lot of 8088/286/386/486 motherboards but I'm still trying to find some rare ones (EISA, SMP, etc.). As a CPU collector since 15+ years, I'm trying to keep at least a working platform (motherboard/memory/storage) for every CPU family.
