STAR Firmware by JonnyC - Source Code and Explanation

Yes, it will work. My first SOIC clip came with a breakout board similar to that and I have done it before. The SOIC clips seem to wear out pretty fast...I can usually get around 300-500 flashes before the plastic starts to get funny. I can usually clean them up and get a little more life out of them but I always keep a spare programmer and clip around.

You can also stick the chip in the clip before reflowing; even the buggered up SOIC clips usually work well for that.

Cool…well in that case

Hopefully this will help someone

P.S. This is the first board I made 100% by myself…yeah…ultra stupid simple…but I’m learning :slight_smile:

And thanks for the tip RMM, I will have to pull some of the ATtinys on my boards I can’t seem to get flashed and flash them with my bum SOIC clip until either these come in or a new clip from Digikey arrives
(I might be able to sneak $1.60 past the wife vs $10~ she put the kabosh on my flashlight spending :frowning: )

Great idea. Thanks WarHawk. Ordered a set.

Dude cause of what I mentioned in that PM last night my flashlight spending is pretty much unquestioned by the wife right now, if you didn’t already order them don’t. I’m ordering a set, I’ll get 6 and send you three, I’m ordering now so if you didn’t already don’t.

Interesting board and idea WarHawk! Thanx! If the press-hold method is not so reliable (dunno), you could use that pencil thingy on the contacts, maybe? Maybe conductive grease?

This is a great alternative to the clip problem... I know my first eBay clip was problems - the metal tabs between the plastic fingers are retracting - they are loose and work their way up (retract), so now I have to push them down manually every couple of times I use it.

Someone does temperature measurement using pure ATtiny13 (frequency vs temperature relation)

Could be nice addition - thermal protection for flashlight.

Good work. The boards like this I normally see are actually ment to be soldered to, they are known as breakout boards and meant for prototyping. They are available for all popular SMD package sizes and pin counts, you use them to hookup hard to work with parts for easy hand wiring or breadboarding. I don’t see a problem using them in the way you describe though, + RMM already said it works ;-).

Another option for this type of flashing is a SOIC ZIF socket such as this one at Adafruit. That might be good for those who have unsteady hands as well.

I’ve actually been thinking about making a board similar to yours, but setup for pogo pins such as these. It would be for in-place programming w/out a clip.

I’ve used a pogo pin programming adapter with the attiny. Pins aligned to press onto the top shoulders of the attiny leads.

Question about these off-time cap’s… If I was planning to run a Zener modded BLF driver off 3 cells (with 3s emitters) would it be better to get 16V cap’s or is that not needed cause with the Zener diode it’ll never see over 4.5V?

It will not see over the zener voltage. EDIT: so the ones comfychair recommended are fine of course.

I am testing whether the 2mm pin header are durable for in circuit programming.

Nice!

What is the part # from mouser/digikey on that SOIC ZIF and the Eagle .lbr file…and I will whip up a nanjg board with that ZIF socket. $15.95 ain’t bad…but why do that when you can DIY right :wink:

Well only place to get that module is adafruit…so might have to go that route…but too ’spensive for my blood at this time…

Maybe try looking up Yamaichi on mouser/digikey, I’ll try and take a look myself later.

What does nanjg have to do with this though?

Speaking of which…most cool

All I know is I’m down for the count…it’s so hard manually holding the SOIC clip and having to have my kid hit the enter key to flash the chips…then if they slip not sure if shorting and possibly frying the ATtiny :frowning:

This one is $5.95 much better price and is 150mil which is the SSU footprint!

This price can’t be right (oh nm…it’s bid only…bleh)

Mouser only seems to carry the 16-pin version. The 8pin version is of course a 16 with 8 pins blocked off. The 16 pin Yamaichi on Mouser costs as much as an 8 pin random-brand already mounted on a PCB costs on eBay.

EDIT: closest product I can find on Digikey is this 3M Textool socket. It costs $25 but looks even easier to operate for those with limited dexterity!

EDIT2: if you are absolutely determined to make a PCB for something, here is the cheapest I see the cheap SOIC-8 socket for - $7.18. I’m not sure why they called it OTS-16-1.27-03 in the listing, maybe they are just reading the marking on the device. The actual part # of the device in their pics is OTS-8(16)–1.27-03 according to the datasheet.

our boards are based off the Nanjg design (more or less) so that’s what I put on the board…just something to put on the tDocu layer so OSHPark would render it

So you want to build a driver board and put a giant 20x18x17mm socket on it?

I see you beat me to the punch with that 2x socket auction. Looks like a good deal, those sockets have the same markings as the enplas sockets I was referring to [OTS-8(16)–1.27-03]. I’m tempted!

Edit: I’ll see your cheap auction and raise you one. The markings on that socket do not seem to be the same as the others however.

Oh nice!!!
(I think I can sneak that one :wink: )

I broke down and “snuck one” myself just now. I ordered mine from here since the listing I linked to before is done. Good luck to both of us with this cheapest of programming sockets… :wink:
