automotive lc filter
I am planning on building a filter/regulator in preparation for my project car. I am still in its first stage, which is constructing a filter/regulator, or voltage stabilizer for my car's electronics.
There are already a lot who have added a set of parallel...
74hc07 pic programer
it would still use all three transistors and would employ additional diodes...
referring to the schematic on the site... i had these thoughts... please comment on them...
- i will only use one transistor for vpp
- transistor networks of t4 and t3 would be eliminated...
propic2 is a good pic programmer. i have one made in a point-to-point wiring and its works great. the problem here is that it is not icsp yet. you have to program the pic the old-school way of remove it from the target app and place it in the programmer.
in the propic2...
the propic 2 (gold or not) does not do icsp. programming takes place the old school way - remove the chip, place it in the programmer and burn. the propic 2 icsp is obviously icsp capable - and it has NO sockets unlike the previous one.
the chipest microcontroller
price is dependent on several aspects.... among these very complicated dependencies is the dealer/source where you would purchase the device, another is the manner of purchasing, another is the brand, etc....
in my case i choose a microcontroller depending primarily...
at89s52 programmer max232
it would depend on the software.
however, if you want to have a max232 to program an 8051 family uC, then go for ds87c420/430/440/450. the process if fully discussed in the ultra-high-speed micrcontroller user guide in maxim/dallas website. they also offer a freely...

what's the real at89isp cable???
or this one:
