You can easily use a PC's printer port for serial-EEPROM programming. You can use a device-programmer circuit used to program the MicroWire serial EE-PROM 93CXX (Figure 1). The circuit is so simple ...

Behold this ATtiny85 based EEPROM programmer. It seems like a roundabout way of doing things, but [Quinn Dunki] wanted to build to her specifications using tools she had on hand. What she came up w… ...

There is a fan underneath the EMP-20 programmer that must have proper clearance to prevent overheating. Please make sure all four feet under the programmer are sitting flat on the shelf.

We all know that solderless breadboards have their limitations. All that stray capacitance can play hell with circuits, especially high-speed stuff, but they’re so darn useful that avoiding t… ...

UV erasable devices can not be erased by the programmer. Therefore they have to be blank before programming. Now look at the Programmer window to see if the Family Module matches what is physically in ...
