Most of us, who are too queasy to try an implant right now, might have our own ideas about the future, and about what's possible. <br /><br />But you and Paul are involved in this more concretely. I'd rather here 'armchair philosophers' who are actually involved, than individuals like myself.<br /><br />Counting the months till the documentary is finished, can't wait.Dan Campbellhttps://www.blogger.com/profile/08382517923175638300noreply@blogger.comtag:blogger.com,1999:blog-4667295582801858613.post-43320305965101863142017-06-03T15:22:36.358+01:002017-06-03T15:22:36.358+01:00I don't understand about 70 percent of this, b...I don't understand about 70 percent of this, but that's some detail.

Pretty much all of them have IIC/TWI interfaces which are used in modern magnetometer chips. <br />Two of the more famous series I'd recommend are the MSP430 series from TI and pretty much the entire attiny/atmega range from Atmel (now Microchip).<br /><br />The MSP430 doesn't come with the same nice open-source easy to use toolchain the attiny/atmega can be used with. However the MSP430 demands a bit less power. My personal recommendation due to simplicity and ease of use would be an attiny861. One of the reasons being I already have working C-code for atmel chips to interface at least two different magnetometers. It also comes with a number of analog input pins which come with an input-buffer that can be disabled and allows you to build a cheap and fast DAC for driving electrodes.<br /><br />As for energy storage I'd either recommend some very pricy medical/space grade lithium based ones. Or , if you'r on a budget, go with rugged NiMH such as the 1/V40H coin cell from varta. They are small, available, rather cheap, easy to handle (if you don't care about fast-charging) and they will take quite some abuse before causing serious trouble (unlike cheap lithium cells which are basically explosives waiting to go off).<br /><br />You may also need a small boost converter to bump your voltages up from the low NiMH cell voltage but that's no big deal. MCP16251/2 will do just fine and you can adjust your desired output voltage on the fly (like upping it in case you need some extra headroom for electrode drivers)<br /><br />Since you are probably going with output electrodes at some point you may need some analog circuitry, namely op-amps. MCP6421/2/4 should serve you well in terms of low-power demand, frequency response and operating voltage.<br /><br />Delivering power for charging the battery is best done via resonant inductive coupling but that's pretty much obvious. I'd go with off the shelf smd inductors and build the thing from a few discrete components instead of using sophisticated IC's for things like Qi.<br /><br />There are a couple of more interesting and potentially useful parts out there, depending on your needs. I also have an experimental electrode-driving circuit which works pretty fine at least on my workbench. Stimulation parameters can be adjusted in software in case it's required.ThomasEginoreply@blogger.comtag:blogger.com,1999:blog-4667295582801858613.post-37405025368463374652017-06-03T11:08:03.179+01:002017-06-03T11:08:03.179+01:00have you considered getting an account on patreon....have you considered getting an account on patreon.com?<br />might be helpfulAnonymousnoreply@blogger.com
